The crop is infected by many diseases prominently fungal diseases which cause limitation in the productivity of the crop. White rust (Albugo candida) and Alternaria blight (Alternaria brassicae) are the most serious fungal diseases of mustard. Methods: The study was conducted to find out the resistant response of mustard varieties against these fungal diseases. A field experiment was conducted to screen the response of mustard varieties in Rabi season of 2021-22 at Research Farm of Amar Singh (PG) College, Lakhaoti, Bulandshahr (UP), India. In India, yield losses from 23 to 54.5% due to white rust and 17-48% due to Alternaria blight has been reported. Result: Among the tested sixteen mustard varieties, four mustard varieties like PT-305, PM-44, Kanchan and MYSL-203 were shown resistant against white rust. Whereas, twelve tested mustard varieties like Jagannath, Radhika, Hybrid-805, Dev-142, Nandi bull, Araurali, 45L46 Lohiya, Kranti, Pusa Mahal, PusaVijya, PM-31 and Rh-149 were susceptible to white rust. Infection of Alternaria blight was observed in all tested mustard varieties. Postules of white rust on lower surface of leaves were starting appear after 5th January (Temperature min. 7°C to max. 19°C). The highest incidence of white rust on leaves was observed from 16th January to 08th February (Temperature range min. 8-10°C and max. 20-22°C). Incidence of Alternaria blight was regularly increasing after 28th January.","PeriodicalId":7599,"journal":{"name":"Agricultural Science Digest – A Research Journal","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85507183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Result: Morphological characterization of 109 genotypes revealed that green yellow was the predominant seed coat colour. Seed coat pattern was absent in most of the genotypes and in rest of the genotypes, speckled type was predominant. The traits viz., bulk density, seed volume and hundred seed weight exhibited high heritability with high genetic advance as per cent of mean. Seed volume, seed thickness, bulk density, seed length and seed breadth evidenced highly significant and positive association with hundred seed weight. PCA analysis revealed that the traits viz., length breadth ratio, bulk density, hundred seed weight, seed volume, seed length and seed thickness contributed to the maximum genetic variability. In addition, it also earmarked the best performing genotypes for each seed related trait.

Genetic variability can be exploited to develop new varieties with higher yield. However, yield is complex and depends on multiple interconnected component characters. Diversity analyses, such as D2 analysis, are used to evaluate the diversity among genotypes and determine the traits that contribute the most diversity in a given population. These analyses are crucial for achieving the goal of developing new varieties with increased yield. Methods: In this study, 323 little millet genotypes were evaluated using an Augmented RCBD, focusing on ten quantitative traits. The experiment was conducted during the rabi season of 2020-2021, and good agronomic practices were followed. D square cluster analysis and path analysis were used to analyze the data, with the \"R\" tool and the \"biotools\" and \"agricolae\" packages, respectively. Result: In this study, 323 little millet genotypes classified into thirteen distinct clusters based on Mahalanobis's D2 statistics, reflecting differences in their phenotypic characteristics. The largest cluster (cluster I) included 243 genotypes, while the smallest clusters (Cluster IX, Cluster X, Cluster XI, Cluster XII and Cluster XIII) had only 1 genotype. The inter-cluster distance varied, with the largest value (577.7) between cluster V and XII.

Oyster mushroom (Pleurotus spp.) is suitable for most of the area and less expensive for cultivation with the availability of paddy straw. Increasing demand of paddy straw compels to search alternate source of substrate for mushroom production. Based on this information efforts were taken to compare many locally available leaf substrates for Pleurotus citrinopileatus production. Methods: Leaf substrates viz., teak, bamboo, maize, banana, coconut, mango, sugarcane bagasse and grass (Dactyloctenium aegyptium) were tested for the cultivation of P. citrinopileatus. Grain substrates viz., paddy, cumbu, bengal gram, green gram, sorghum, black gram, ragi and the above leaf substrates were studied for their effect on radial mycelial growth and dry weight of P. citrinopileatus. Result: All the leaf substrates were on par with each other for radial mycelial growth. Highest mycelial dry weight of 724.67 mg was recorded in paddy straw. Among the different leaf substrates used for mushroom bed preparation, banana leaf substrates showed highest yield of 115.00 g than paddy straw.

Methods: A field experiment was conducted during the rabi season of 2019 and 2020 at the experimental research farm, School of Agricultural Sciences, Nagaland University, Medziphema. The experiment consisted of six varieties of oat, namely, V1-OS-346, V2-OS-403, V3-WJ-8, V4-OS-6, V5-OS-7 and V6-OS-377, which were laid out in randomized block design (RBD) with four replications to find out the best suitable variety under rainfed condition of Nagaland.

Maintenance of germination and vigour requires new alternative method of storage conditions viz., packaging material and temperature conditions. Storage potential of groundnut seeds cv. VRI 8 and the changes associated with the seeds stored under different storage conditions were investigated in this study. Methods: The efficiency of modified atmospheric storage with different combination of CO2, N2 and O2 and vacuum packaging under different storage temperature (25°C, 5°C and -5°C) for maintaining the storage behaviour of seeds up to 8 months were evaluated and the gas mixture was checked in gas analyzer at regular intervals. Result: The seeds stored under modified atmospheric storage (MAS) condition with a gas mixture of 0% CO2, 100% N2 and 0% O2 at -5°C temperature condition, maintained germination and seed vigour above 70% with a minimum increase in seed moisture content even after 8 months of storage and even when these seeds kept under ambient condition also maintained germination above 70% after 8 months of storage while the seeds stored under ambient condition registered less germination of below 70% by 6 months of storage itself. Down-regulation of antioxidant defence system viz., catalase and peroxidase activity and the minimum accumulation of malondialdehyde and H202 content in the embryo indicated the less oxidative damage in the seeds stored under MAS compared to ambient condition. Thus, the study highlighted that the seeds have better storage potential under modified atmospheric storage condition with low atmospheric temperature through maintaining the seed quality by reducing their metabolic activity and storing these seeds under ambient condition could be a cost-effective method.\u0000","PeriodicalId":7599,"journal":{"name":"Agricultural Science Digest – A Research Journal","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90413087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
