Development of climate resilient home garden model for year round production for improving resource-poor household food and nutritional security in Eastern India Kumari Shubha, Anirban Mukherjee, Ujjwal Kumar, Tanmay K. Koley and Arbind K. Choudhary
ICAR RESEARCH COMPLEX FOR EASTERN REGION, PATNA
Abstract
Indian Government has long worked to improve food security and reduce poverty and hunger in eastern Indian states.The eastern states are facing malnutrition problems much more than other parts of the country. Vegetables are the sufficient and cheaper source of nutrition. Home gardens can play an important role in providing enhanced food supplyand increased diversity of food to some extent. A model of 100 m2 and 200 m2 were developed and established at ICAR-Research Complex for Eastern Region, Patna, India during the year 2019-20. In the winter season from 637g and 596g vegetables were produce per head per day from 100m2 and 200m2 models respectively. Similarly in the summer season 478.22g and 487g vegetables were produce per head per day from 100m2 and 200m2 models respectively. Home garden can provide a significant percentage of the recommended dietary allowance (RDA) for protein (35%), essential fat (25%), micronutrients like iron (26%), zinc (19%) calcium (20%) and essential vitamin like vitamin A (138%) and vitamin C (211%). Predominately solanaceous vegetables, cole crops and cucurbits were grown in home garden. But if majority of commercial vegetable could be replaced by climate resilience, nutri-dense, legume vegetables, availability of protein, iron and zinc will increase significantly from 35 to 60%, 26 to 55% and zinc 19 to 40% respectively.

Study of the use of True Shallot Seed ( TSS) that have been stored for 2 years and their production in the Sibolangit farmer group, North Sumatra Sortha Simatupang , Tumpal Sipahutar , Imelda Marpaung dan Evawati Sri Ulina
BPTP Sumatera Utara, Kementan RI
Abstract
The purpose of this study: To determine the decrease in vigor of seeds from the botanical seeds of shallots after being stored for 1 and 2 years, and the productivity of the consumable tubers produced.
This research was conducted in January - July 2020. The germination research was conducted at AIAT North Sumatra Medan. The study used a non-factorial completely randomized design with 10 replications. The treatments are: seed storage, namely:
S1) in the refrigerator, wrapped in plastic + silica gel, stored for 2 years- S2: in the refrigerator, wrapped in plastic, in a sealed can + silica gel, stored for 2 years S3): in an air-conditioned room, in Al foil, stored for 2 years- S4: in the refrigerator, wrapped in plastic without silica gel, stored for 1 year- S5) control: new harvest
Seeds that grew normally from each treatment were planted in the field as planting material for the production of bulbs for consumption of shallots. The location is on the land of the Arih Ersada farmer group in Sibolangit Deli Serdang, North Sumatra.
The results showed: The best treatment was storing the seeds in plastic in cans that were given silica gel and stored in the refrigerator. In this treatment the decrease in germination was lowest compared to other treatments. Field tests did not show any difference in plant vigor. The productivity produced by farmers from the treatment of stored seeds reached 15 t/ha, and there was no difference in storage treatment for storage time, packaging and storage. Production costs increase due to additional costs of purchasing seeds due to decreased normal germination. This means that the seeds are still suitable for use.

Spodoptera Exigua Pest Control Strategy on Shallots Through Intercropping with Aromatic Plants Lilis wulandari, Rika Despita, Gunawan
Politeknik Pembangunan Pertanian malang
Abstract
Spodoptera exigua is the main pest on shallot plants. The attack rate can reach 40% which results in a decrease in onion production. One way of controlling the environment that is environmentally friendly and reduces pest resistance is by intercropping using aromatic plants. This study aims to control the pest attack Spodoptera exigua. The research method used a randomized block design with 4 treatments, namely: monoculture (P1), onion and celery intercropping (P2), onion and mint intercropping (P3), onion and rosemary intercropping (P4). Each treatment was repeated 6 times so that there were 24 experimental units. In each experiment, the calculation of farming analysis was carried out. Observations of pests were carried out on colonization, attack area, attack level, and intensity of attack of Spodoptera exigua. Observations of plant growth and production were carried out on plant height, number of leaves, and weight of fresh and dry bulbs consumed. The results of observations of pests were analyzed descriptively and the results of observations of plant growth were carried out using ANOVA and DMRT tests at 5% level. The results showed that colonization, attack area, level of attack, the intensity of attack of Spodoptera exigua was the lowest intercropping shallot with rosemary. Plant height, number of leaves, fresh weight of tubers, and dry weight of tubers were best consumed by monoculture treatment, but based on the analysis of farming the most profitable was the intercropping of shallots with rosemary.

CHARACTER SELECTION OF SHADE-LOVING TOMATOES AND GENETIC INTERACTION X SHADE TYPE ON TOMATO PLANTS PRODUCTIVITY Dwiwanti Sulistyowati, Arya Widura Ritonga
Bogor Agricultural Development Polytechnic
Abstract
Low light stress causes a variety of changes in morphology, anatomy, and phenology, these changes are intended to capture more photons in low light. This study consists of two experiments, the aim (1) this study was to investigate morphology, anatomy, and phenology characters of shade-loving tomato genotypes at low light intensity- and (2) the genetic interaction and shade type on the yield of tomato plants. The experiment was carried out from January 2015 to March 2018, arranged in a nested design in the form of 2 factors (shade type and tomato genotype) with 3 and 4 replications. The first factor consisted of two types of shade, namely without shade (0%) and 50% shading (first experiment), added corn shade, and papaya shade (second experiment). The tomato genotypes used in the first experiment consisted of four shade-loving genotypes (SSH 3, Medan 4, Papua 2, Maros 3), four shade-tolerant genotypes (Karina, Tomat kecil 1, SSH 9, Bogor), and four shade-sensitive genotypes (Kediri 2, Brastagi 6, Marglobe, F 6005001-4-1-12-5). The second experiment consisted of a shade-loving genotype (SSH3), a shade-sensitive parental genotype (4979), five cross-breeding genotypes (370-1, 384-11, 326-4, 380-16, and 381-11), and three commercial varieties (IPB Tora, Karina, and Palupi). The first experimental results of shade-loving tomato genotypes at low light intensity showed an increase in plant height, leaf number, maintaining high stomata density, reducing leaf thickness and palisade height, and flowering time and harvesting time. The second experiment results showed that genotypes 370-1 and 384-11 were 50% shade-loving genotypes, had better production than commercial varieties. Genotypes 380-13, SSH3, and 4979 were shade-loving papaya genotypes, tomato genotypes 326-4, 380-16, and 381-11 were shade-loving maize genotypes- and has a production that tends to be better than commercial varieties.

Abstract
The cultivation of shallots with seed propagation (TSS/True Seed of Shallot) is one of the efforts to resilience and healthy diets. Therefore, TSS becomes an alternative material planting of shallot in Indonesia. Aplication of paclobutrazol after maximum vegetative fase in shallot planted from seeds will inhibit vegetatif growth and accelerate translocation photosynthate to shallot bulbs. This research was arranged in RCBD with two factors and three blocks. The first factor was cultivars (Tuk Tuk, Sanren and Lokananta), and the second was the paclobutrazol dosages (0, 15, 30 and 45 mg L-1) which was applied twice at 20 and 35 dyas after planting (dap). All Data obtained were analyzed for α-=5% variance analysis and followed by DMRT α-=5% test. The results showed the applications of 15 and 30 mg L-1 paclobutrazol effectively inhibited the plant height at 40-50 dap and the number of leaves at 30-40 dap, but increased nitrat reductase activity at 30 dap, total leaf chlorophyll content during plant growth, net assimilation rate, plant growth rate, total dry weight, bulb number and productivity compare to the plants with application of 45 mg L-1 paclobutrazol and untreated plants. Sanren, Lokananta and Tuk Tuk showed potential higher yield with formation of 5.50, 3.17 and 2.49 bulbs per plants, respectively. The optimum paclobutrazol dosage was 22.75 mg L-1 with a productivity increased by 29.07% compared to untreated plants.

Abstract
Shallot (Allium cepa L. Aggregatum group) is an important commodity since it is used for spices, traditional medicines, and healty diet components. Growth and yield shallot plants from TSS affected by different transplanting ages were determined in the research in RCBD with two factors and three blocks. The first factor was the transplanting time (4, 6, 8, and 10 weeks after sowing), and the second factor was the TSS varieties, i.e., Sanren, Tuk Tuk, and Lokananta. Analysis of variance α- of 5% was performed on growth and yield data and continued with Duncan^s Multiple Range Test (DMRT). The results showed that transplanting 4-6 weeks ages. Seedlings provided higher plant height, leaf area, root, plant growth rate, and plant yield than those in transplanting 8-10 weeks ages seedlings. Seedling transplanted at 4-6 weeks ages could produce yield 20.07 to 23.03 tonnes. ha-1 while Seedling transplanted at 8-10 weeks ages produced yield 14.51 to 16.19 tonnes. ha-1. The treatment of varieties showed no significant difference in yield, which Tuk-Tuk, Sanren, and Lokananta had 21.20, 17.39, and 16.75 tonnes.ha-1, respectively. However, Sanren formed more bulbs per plant (4 bulbs) than Tuk-Tuk, which only formed two bulbs. We concluded that Sanren, Tuk Tuk, and Lokananta seedlings could be transplanted after 4-6 weeks of age.

Abstract
Banana blossom is a by-product of the of banana plants which limited utilization for human. It contains of anthocyanin that is potentially as natural dyes in the food industry. Anthocyanin from banana blossom can be extracted using Ultrasonic Assisted Extraction (UAE) method. UAE is a non-conventional extraction method with ultrasonic waves. In addition to the frequency applied during the treatment, UAE is affected by the duration of sonication for producing the high yield. Therefore, this study aimed to determine the effect of the duration of sonication treatment on anthocyanin yield in banana blossom extract. Experimental design applied in this research is randomized group design with five treatments namely maceration for 24 hour, sonication: 5 minutes, 10 minutes, 15 minutes and 20 minutes. Sonication was carried out at 40 kHz. Parameters determined were anthocyanin yield and color (L*, a*, b*). The results showed that the appropriate treatment for producing the anthocyanin from the banana blossom is UAE with 5 minute sonication treatment. This treatment produces a total anthocyanin of 87.31 mg/L with color parameters: L*, a*, and b* values of 28.67- 12.54 and 17.92, respectively.

Abstract
Garlic (Allium sativum L.) is a horticultural commodity of high economic value in Indonesia. Sembalun Highlands in West Nusa Tenggara Province is one of the largest garlic producing regions in Indonesia. Garlic is mostly grown in irrigated highlands therefore domestic production is very limited, only supplies 17.5% of domestic demand. One of the main constraints facing in post-harvest storage is seed-borne fungal contaminants. The objective of this research was to investigate fungal contaminants on garlic seeds in Sembalun Highlands. This research was conducted in October-December 2018. Samples (Sangga Sembalun garlic seeds) were collected from garlic post-harvest storage in Sembalun Highlands, whilst laboratory analysis and identification were conducted at the Biology Laboratory, Faculty of Mathematics and Natural Sciences, Mataram University using Blotter on Test method. Based on the laboratory identification, there were two main soil-borne fungal contaminants isolated from garlic seed samples. Observation under microscope with 400x and 1000x magnification indicated that those fungal contaminants were Aspergillus sp. and Fusarium oxysforum. Aspergillus sp. was identified based on it^s morphology especially conidia and conidiophores whiles F. oxysforum was identified based on microconidia and macroconidia. It is well known that F. oxysforum is plant pathogenic fungi on garlic worldwide.

Abstract
Tomato is among the most cultivated vegetable crops worldwide, and bacterial wilt (BW) caused by bacteria of the Ralstonia solanacearum species complex (RSSC) is the most devastating disease affecting tomato impacting food and nutrition security in many areas. Pesticides used for controlling plant diseases are hazardous to producers, consumers, and the environment, whereas biological control is a sustainable and environmentally safe alternative for disease management. To identify efficient biocontrol agents (BCAs), twenty-five potential BCAs isolates were screened for control efficacy to BW on ten-day-old tomato seedlings of highly susceptible (L390) and moderately resistant (L180) varieties previously inoculated with R. solanacearum strain PSS4 (=Asian origin, Race 1, Phylotype I- Biovar 3). After ten days of incubation at 28C in the growth chamber, wilting (W%) and biocontrol efficacy (BE%) percent were evaluated. Of the 25 BCAs tested, four significantly reduced W%, with BE% ranging from 50% to 80% for both varieties. The four BCAs isolates were identified as Talaromyces sp., Trichoderma sp., Bacillus sp., and variovorax sp. The seedling method allows the rapid and cheap in vivo screening of many potential BCAs to reliably identify those with higher bacterial wilt control efficacy for further testing.

Abstract
Winged bean is a tropical vegetable crop that has the potential to be developed as legumes. Quality of young pod of winged bean can be determined by the age of harvest. This study aims to determine the production and quality of two varieties of winged bean pods with different harvest ages. The experiment was carried out from September 2020 to February 2021 at IPB experimental station, Darmaga, Bogor. The experiment used a factorial completely randomized block design with three replications, namely two winged bean varieties (Fairuz IPB and Sandi IPB) and harvest age (8, 10, 12, and 14 days after anthesis (DAA)). The results showed that the two varieties had different production and quality of young pods. Fairuz had higher number of flowers, the number of pods, total weight, and productivity of young pods compared to those of sandi. Sandi had high scores on pod length, pod softness, and anthocyanin content. The delay in harvesting caused the weight of young pods and productivity of young pods at the age of 14 DAA to be higher. Young pods harvested at 8 DAA were the softest and had the lowest thickness, and can be recommended to harvest the young pod.

Vegetable Ensures Nutrtion Security Prem Nath
Vegetable Science International Network (VEGINET)
Abstract
Food is main source of human healthy diet, which is composed of grains, vegetables and fruits, tubers and roots. Food or these crop plants contain nutrients, the consumption of which provides nutrition security to human. The present presentation will discuss about the food crisis, nutrient crisis and health crisis and illustrate the contribution of vegetables in challenging and mitigating those crises.
It is reported that about 821 million people suffer from hunger and malnutrition (FAO) whereas, over 3 billion people suffer from micro-nutrient deficiency worldwide.
Without consumption of vegetables, micro-nutrient deficiency cannot be evaded or controlled. Evidences ensure that immunity against both non-communicable and communicable diseases could be enhanced through consumption of healthy diet including vegetables and fruits.
The World Health Report 2002 indicates that about 2.7 million people could be potentially saved against non-communicable diseases by adequate consumption of vegetables and fruits. The recent literature indicate that healthy diet promotes immunity to diseases including the deadly Covid - 19 presently affecting human around the world.

Farmer^s willingness to grow garlic, a high value horticulture crop, is one of the important factor to food self-sufficiency through production. The purpose of this study was to analyze the willingness of Sembalun farmers to grow garlic and its determinant factors using theory of planned behavior (TPB) approach. This study used a primary data from a survey of 157 garlic farmers in Sembalun sub-district, West Nusa Tenggara. Data were analysed using scoring and Structural Equation Modeling-Partial Least Square (SEM-PLS) analysis. The results showed that willingness of Sembalun farmers to grow garlic was at a moderate level with a score in between 33.34 and 66.66. Attitude, subjective norm, and behavioral control had a positif and significant effect on Sembalun farmer^s willingness to grow garlic. Meanwhile, Sembalun farmer^s willingness to grow garlic was not affected by knowledge of farmers, farm size, and age. This study recommends that increasing the willingness of farmers can be achieved by improving the internal factors such as attitude, subjective norm, and perceptions of behavioral control to grow garlic and external factors in the micro, meso and macro levels.

Rice to Rise: Development and Utilization of Rice Hull Paper Bags in Rice Retail Stores in Southern Leyte, Philippines Eden Vina L. Grate, Jolina S. Ladan, Rovic D. Oppus, and Pet Anthony L. Pascual
Department of Food Science and Technology, Southern Leyte State University-Main Campus
Abstract
Rice hull is regarded as one of the Philippines^ most abundant biomass resources and present an environmental problem concerning its disposal. Milled rice is typically purchased in small quantities and packaged in non-biodegradable plastic packaging. Hence, this project aims to develop a rice hull based paperboard packaging as alternative to non-biodegradable plastic packaging used in rice retail stores. The procedure involves alkali treatment to produce pulp from rice hull, bleaching with sodium hypochlorite, binding, sheet forming using a flat metal sheet compressor, and sewing. The result of this project will primarily reduce the ecological impact of open burning of rice hulls, demonstrate the feasibility of substituting wood chips used in paper-based packaging and thus reducing deforestation, and become a sustainable alternative to plastic packaging commonly used by rice retail stores in the Philippines.

VEGETABLES FOR FOOD SECURITY AND ECONOMIC GROWTH Idha Widi Arsanti, Henri Wira Perkasa
Indonesian Center for Agricultural Education
Abstract
The agriculture sector is one of the sectors that showed a positive trend during the Pandemic Covid-19 in Indonesia. This positive trend is partly contributed by an increase in horticultural products such as fruits and vegetables during the period. Vegetables are considered a highly-valued commodity recently because the demand for vegetables shows a steady increase in domestic and international markets. The growing number of middle-income class people in urban areas consider vegetables an essential source of nutrition for their dietary lifestyle. This is an opportunity for the agriculture sector in Indonesia to capture a larger market for vegetables both domestically and globally to contribute toward national food security and economic growth purposes. However, vegetable farming in Indonesia still faces several challenges, both in productivity and structurally, to gain a competitive advantage. Using secondary data, this paper aims to explore vegetable farming in Indonesia by assessing market potential, production, and supply chain issues. The paper finds that the domestic market is as potential as the international market for vegetable products. Yet, farmers are still experiencing low productivity and high production costs that impact their incomes- the structure of vegetable farming is still dominantly conducted by small-scale farmers- a long supply chain- and other environmental issues such as the high use of chemical fertilizers and pesticides- and the expansion of vegetable farming in protected areas. To overcome these challenges, some approaches could be taken: improving the quality of inputs, involving the youth, promoting good agricultural practices, introducing off-season technology, and improving financial access for farmers.

Abstract
Vegetable farmers in food estate area of Humbang Hasundutan are seeking new types of collaborations and economic opportunities in the new adaptation era. Market opportunities, however, have incurred demanding environmental, financial and labour requirements, and created trade-offs between expanding cash crops and maintaining livelihood security. There are different collaborative models between vegetable farmers and other social agents (suppliers, industries, markets, government, non-governmental organizations) have emerged. Local farmers are engaging in collective actions and pursuing different types of partnerships, which facilitate knowledge exchange and access to market niches, also helping them overcome the infrastructural and logistical deficiencies that have historically limited rural development in this area. We examine the challenges and opportunities these partnerships and social innovations have created for local farmers, who are part of heterogeneous groups with distinct roles, assets and contexts. The state, food estate program posed challenges to small-scale vegetable farmers who experienced asymmetrical relationships within their partnership with private companies. Farmers should be pushed to be more flexibility in deciding their production arrangements, developing new farming techniques, and pursuing commercialization pathways. Despite their limited power, small-scale vegetable farmers have been able to overcome some structural barriers through innovations, entrepreneurship, and renegotiation of contract farming. Thus, their ability to engage in food estate programs provides concrete examples of the potential of governance based on collaborative arrangements to support sustainable vegetable farming systems.

Jl. Sinarmas Boulevard Nomor 01, Situ Gadung, Kec. Pagedangan, Tangerang, Banten 15338. Indonesia
Abstract
As an important sector in Indonesia, agriculture is facing serious challenges in the middle of agri-food value chain transformation. This sector is dominated by smallholder farmers who occupied less than 0,2 hectares of farm area, have poor education and skills, and are in the middle aged-old group. Thus, it may hamper the development of agriculture as it is difficult for these farmers to improve their business capability. It can be seen from the Gross Domestic Product (GDP) that tend to decrease annually. Meanwhile, scholars argued that the agri-food value chain transformation led to a better opportunity for farmers to capture more benefit from the emerging value chain. On the other hand, the emerging value chain also present more barriers that may not be addressed by smallholder farmers. This situation led to a question, what are the options for smallholder farmers to capture value from the emerging value chain system and how? This paper presents and discuss findings from studies in the area of agri-food value chain, includes options for smallholder farmers to participate within the value chain system and how, so that they can capture more value from it. A combination of market upgrading, process upgrading, and upgrading value governance can be options for smallholder farmers to participate within the transformation. However, these strategies cannot be achieved by smallholder alone. It required intervention from the external environment such as infrastructures, financial access and legislation as well as external agents from government, Non-Government Organisation, research agency, and private sectors.

COMPARATIVE ANALYSIS OF ECO-FRIENDLY AGRICULTURE AND MARKETING INNOVATION ON SHALLOT FARMING (Case Study: Lestari Mulyo Farmer Group, Selopamioro Village, Imogiri Subdistrict, Bantul, Yogyakarta Special Region) Tri Martini, Kurnianita, and Hano Hanafi
Yogyakarta Assessment Insitute for Agricultural Technology
Abstract
The habit of farmers selling crops with sistem slash is a practice of buying and selling by the contractor by buying agricultural products before entering the harvest period. The practice of buying and selling without perfect exchange sometimes leads to the vagueness of the number of goods sold, so it can cause losses to one of the parties. Semi-organic farming is a form of soil processing and cultivation of crops by utilizing fertilizers derived from organic materials and chemical fertilizers in minimal quantities to increase the nutrient content of the soil. Semi-organic farming can be said to be environmentally friendly agriculture because it can reduce the use of chemical fertilizers to above 50%. Based on this concept, the purpose of this study is 1). Know the difference in production costs, receipts, and revenues from semi-organic and inorganic, 2). Know the difference in profit and feasibility of farming from sistem marketing slash and weight-based corporation. Sample determination using Non-Proposional Stratified Random Sampling method with the number of samples for semi-organic farmers is as many as 20 samples or respondents and inorganic as well as as many as 20 respondents. Quantitative descriptive data analysis as well as statistical tests (independent sample t-test). Analysis of shallot farming with environmentally friendly technology applied by farmers in Nawungan Bantul shows the profit obtained by farmers per hectare is Rp. 129,720,000 within +/- 50 days (1 season of planting shallots) compared to the inorganic system of Rp. 58,430,000. Production reached 15 tons/ha with an average price of Rp 17,000/kg (how to sell weight) with a total receipt of Rp 125,280,000. The average B/C ratio in shallot farming harvested by 1.03, greater than the slashed ratio of 0.952. The feasibility of semi-organic shallot farming (environmentally friendly) with marketing using corporate institutional innovations (weighing non-slash) showed the highest figure of 2.03.
