Assessing farmers knowledge towards Agri-Nutrition (A2N) in Uttar Pradesh and Telangana: A psychometric test development and impact analysis
Food environments improve the health and nutrition benefits of populations. Rapidly changing food systems, production and distribution patterns stress out to leverage the role of agriculture for nutrition. This requires enquiring the knowledge of farmers in both the fields of agriculture and nutrition for appropriate decision-making. The present study attempted to investigate Agri-Nutrition (A2N) knowledge level of 360 farmers from two agro-climatic regions of Uttar Pradesh and Telangana villages with a reliable and valid instrument development based on psychometric principles. The items with difficulty index (20-80), discrimination index (>0.2), point-biserial correlation (>0.2) were selected and administered to final sample. The findings indicate targeted efforts of providing nutrition education in model villages contributed to improved knowledge among farmers, which in turn positively affect nutrition security in the study area.
Amelioration of cold stress in marigold var. Pusa Narangi Gainda under North Indian plains
This experiment was conducted to investigate different strategies for alleviating cold stress in marigold for a period of two consecutive years (2021-2022 and 2022-2023) at the Centre for Protected Cultivation Technology (CPCT), ICAR-Indian Agricultural Research Institute, New Delhi. In this study, the marigold var. Pusa Narangi Gainda seeds were sown at three distinct sowing dates and seedlings were grown under two different growing conditions with the use of several treatments and their respective combinations. The parameters pertaining to growth and flowering were recorded and evaluated. Among distinct growing environments, the plants grown inside a low polytunnel were seen to exhibit superior growth compared to those under open field conditions. Whereas, in terms of the sowing date, October 15th recorded maximum in growth and flowering characteristics. In the context of various treatments, it was discovered that the combination of Chito Oligosaccharide at a concentration of 300 ppm with Arbuscular mycorrhiza showed favourable results as compared to control and other treatments. This study demonstrates the positive impact of utilizing low polytunnels under various sowing dates and treatments on the growth and flowering of marigold plants.
Influence of organic inputs and growing conditions on yield and yield related attributes of strawberry (Fragaria x ananassa Duch.)
Studies were conducted to evaluate the “Influence of organic inputs and growing conditions on yield and yield related attributes of strawberry (Fragaria x ananassa Duch.)” in the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat during the period 2020-2022. The field experiment was laid out in Factorial Randomized Block Design (RBD) with five treatments replicated three times under four different growing conditions with spacing of 30cm x 60cm. The four different growing conditions were rain shelter with insect proof net (S1) (top covered with 200 micron UV film and side wall of 40 mesh net), rain shelter without insect proof net (S2), net house (50% shade) i.e. S3 and open condition (S4). Treatments were FYM @ 180 g/plant (T1), rock phosphate @ 4.50 g/plant + microbial consortium @ 0.063g/plant (T2), T2 + vermicompost @ 45 g/plant (T3), T2 + enrich compost @ 45 g/plant (T4) and T2 + poultry manure @ 45 g/plant (T5).) .The yield attributes viz. number of fruit retained (19.33 nos), length (5.38 cm), diameter (4.26cm), volume (19.45 cc), average fruit weight (23.65g), fruit yield (457.88g/plant) was also found to be significantly higher in treatment combination T3S1 vermicompost @ 45 g/plant+ rock phosphate @ 4.5 g/plant + microbial consortium @ 0.063 g/plant in growing condition S1) in pooled analysis of both the years.
EFFECTS OF GENETIC AND NON-GENETIC FACTORS IN GROWTH PERFORMANCE OF THE SHEEP BREEDS
Genetic enhancement in livestock can be realized through selection and breeding systems in which the influence of genetic and non-genetic factors on productive traits is the utmost imperative feature for obtaining accurate estimates of breeding values. This study was carried out to analyze the genetic and non-genetic factors influencing the growth performance in sheep breeds. The data on the body weight of Kilakarsal, Vembur, Chevaadu, Ramnad White, and Mecheri sheep breeds at different ages were collected for a period of 10 years. The mean daily gains from birth to the weaning period (90 days) and from weaning to one year were estimated. Statistical analysis was performed using R software. The least-square means of birth weight of Kilakarsal, Vembur, Chevaadu, Ramnad White, and Mecheri were 2.4±0.01, 2.62±0.01, 2.37±0.10, 2.57±0.12 and 2.39±0.16 kg, respectively. The least-square means of one-year body weight of Kilakarsal, Vembur, Chevaadu, Ramnad White, and Mecheri were 19±0.16, 19.9±0.16, 21.6±1.62, 24.9±1.62 and 22.9±2.28 kg, respectively. The phenotypic correlations among birth weight and body weights at successive ages showed positive values and varied from low to high. This directed that selection for body weight at birth and or earlier ages would result in genetic improvement in successive ages. At birth, there is no significant difference among breeds. But as age advances breed differences occur. Ramnad White and Chevaadu are heavier than Kilakarsal and Vembur breeds. The effect sex of sheep on body weight was significant. In the selection and breeding programs, the consequences of environmental factors should be included.
Evaluation of antifungal effect of various organic and inorganic salts against Fusarium oxysporum f. sp. pisi causing wilt of pea
Pea (Pisum sativum) is leguminous plants used as food, fodder and vegetables for humans and animals worldwide. Harvesting peas is an important winter crop around the world, including India, which requires cool and moist conditions. The fungal root pathogen Fusarium oxysporum f. sp. pisi, along with other pathogens causes massive losses in pea. An experiment was performed during May-June 2022 at the department of Plant Pathology, College of Agriculture Jabalpur (M.P.) to evaluate the inhibitory activity of twenty organic and inorganic salts was evaluated in the study against Fusarium oxysporum f. sp. pisi at 1.5 and 2% (w/v) concentration. Sodium carbonate (5.00) reduces maximum radial growth of test pathogen at 1.5% (w/v) concentration and result 93.80% growth inhibition, also complete inhibition at 2% recorded. In both 1.5 and 2% (w/v) concentration, ammonium acetate, potassium sorbate, sodium benzoate, sodium metabisulphate and trisodium phosphate completely reduce the mycelial growth simultaneously all these salts results 100% radial growth inhibition. At 2% (w/v) concentration percent growth inhibition was also recorded good in many salts like ammonium carbonate (97.31%), ammonium molybdate (93.18%). MFC, MIC and ED 50 value of salts were tested and all of the salts tested had MIC values that were in agreement with ED50 values.
