Effect of plant growth regulators on shelf life of Guava (Psidium guajava L.) under high density plantation in Jammu subtropics

Paper ID- AMA-05-04-2023-12164

Effect of plant growth regulators on shelf life of guava (Psidium guajava L.) under high density plantation was carried out at Research Farm, SKUAST- Jammu, Chatha during 2021-2022. There were 9 treatments comprising of foliar application of NAA @ 100 and 150 ppm, GA3 @ 75 and 150 ppm, applied individually, NAA 100 ppm in combination with GA3 75 ppm, NAA 100 ppm in combination with GA3 150 ppm, NAA 150 ppm in combination with GA3 75 ppm, NAA 150 ppm in combination with GA3 150 ppm and control (spray). During investigation it was observed that all physical and biochemical parameters of guava showed a decreasing trend with advancement in storage intervals. Application of NAA 150 ppm in combination with GA3 150 ppm recorded minimum mean physiological loss in weight of guava fruit (4.69 %), Highest mean rotting percentage of guava fruits (8.89 %) , Maximum mean fruit length (6.85 cm), Maximum mean fruit breadth (6.85 cm),Maximum mean fruit weight (140.28 g), Maximum mean fruit volume (134.29 cc), Maximum mean fruit firmness (6.75 kg/cm2),Highest mean TSS of guava fruits (10.66° Brix), Maximum mean ascorbic acid (173.39 mg/100g fresh wt.), Lowest mean titratable acidity (0.31 %), highest mean organoleptic rating of 6.87. Overall, it was concluded that NAA 150 ppm plus GA3 150 ppm resulted in longer shelf life when stored under optimum conditions.

Technological and Extension yield gaps in green gram in Thiruvarur district of Tamil Nadu, India

Paper ID- AMA-03-04-2023-12159

The technological gap between existing and recommended technologies of green gram crop was studied during 2018, 2019 and 2020. During the study period a total of 150 Front Line Demonstrations (FLDs) were conducted on farmers’ fields in Salipery, Vaduvur, Radhanallur, Alangudi and Needamangalam villages of Thiruvarur district. The findings of the study revealed that the improved technology recorded a mean yield of 9.73 q/ha which was 31.47 % higher than that obtained with farmers practice (7.29 q/ha). The study exhibited mean extension gap of 1.95 q/ha, technology gap of 2.57 q/ha and with mean technology index of 20.88 per cent. An additional investment of Rs. 2091/ha coupled with Yellow Mosaic Virus (YMV) resistant varieties, seed treatment with bioagents, recommended seed rate and need based plant protection measures resulted in additional mean returns of Rs. 14227/ha. Hence, higher effective gain of Rs. 12135/ha with incremental benefit cost ratio of 6.76 was obtained with improved technologies.

Market Participation of Smallholder Vegetable Growers: Concepts and Evidences from Different Agro-Climatic Zones of Himachal Pradesh

Paper ID- AMA-02-04-2023-12158

This paper investigates the factors related with smallholder vegetable growers’ market participation in different agro-climatic zones of Himachal Pradesh. A Stratified multistage random sampling technique was used to select 400 vegetable growers. The selection of sampled households was done from all the four agro-climatic zones of the state. Two blocks from each agro-climatic zone were selected purposively for the present study. Farmers gained market information via mobile phones and neighbors/relatives who had already sold their products since they are easily accessible and trustworthy. STATA version 16 was used to analyze the primary data by using a Multinomial Logistic regression model. The findings revealed that a farmers’ participation in nearby market is influenced by distance to market, road infrastructure, and quantity to produce. On the other hand gender, distance to market, market information, education, road infrastructure, and quantity to produce influence farmers’ participation in distant markets. Government intervention encouraged policymakers to enhance farmers' access to market information in order to improve their decision-making on vegetable market participation. There is an urgent need for the government to invest in developing road infrastructure, especially feeder roads that connect farms to major highways.

Millets for Global Human Health – A comprehensive review

Paper ID- AMA-30-03-2023-12156

Climate change, water scarcity, escalating food bills, population growth, and other social implications are probable to substantially endanger agricultural and global food security in the twenty-first century, particularly for the world's poorest residents who live in deserts and partitions. Scientists and nutritionists are challenged by these effects to look into the production, processing, and consumption of alternative food sources in order to eradicate eagerness and poverty. The world's main food supply and a large portion of the diet of the ordinary human are cereal grains. Millet, which is also a significant source of carbs and proteins for the locals, is a drought-resistant crop in Africa and Asia's semi-arid tropical areas. Furthermore, millet grain is gaining popularity among technologists, food scientists, and nutritionists due to its important impact on national food availability and potential medical benefits. To assess the possible health benefits and nutritional worth of millet grains, this report reviewed recent advancements in the research that had been conducted up to that point. As well as the difficulties, constraints, and prospects for promoting millet use as food for a vast and expanding population, processing technologies used to enhance the millet's edible and nutritional qualities are examined.

Effect of Seed priming with metallic nanoparticles on germination, growth and biochemical properties of citron (Citrus medica L.)

Paper ID- AMA-29-03-2023-12155

Exploration of nanoparticles (NPs) in the field of agriculture opened a great and remarkable attention because of its unique propensity and high surface reactivity. The efficacy of different metallic silver and copper nanoparticles were used to determine seed germination, growth and biochemical properties citron (Citrus medica L.). Citron seeds were treated with metallic AgNPs (<90nm) and CuNPs (50nm) suspension using stabilizing agents poly ethylene glycol (PEG) @ 6000 ppm to prevent particle aggregation and electrostatic repulsion and incubated for eight hours at 225 rpm in an orbital shaker. The seeds treated with AgNPs enhanced the germination percentage (98.33–100.00%), mean germination time (29.25–33.25 days), germination rate of seeds per day (1.89–2.10) and germination index (4.77–5.33) as compared to CuNPs and non-treated seeds. The seedlings kept under protected condition performed better than open condition. AgNPs @ 20 ppm showed the maximum plant height (13.94 cm and 14.20 cm under open and protected condition respectively), maximum root length (32.51cm in open and 33.67 cm in protected condition), leaf emergence rate (10.33 under open and 10.87 under protected) and maximum fresh weight (5.00 g) and dry weight (1.57 g) of seedlings at120 days after germination (DAG). AgNPs @ 5 ppm improved total chlorophyll content (0.80 mg g-1) in leaves. The highest total phenolics (8.59 mg GAE 100g-1) content in leaves was recorded in CuNPs @ 40 ppm.
