Moench] is important to improve productivity of this crop. Given that a breeder’s primary goal is production, it’s critical to understand the connections between the traits that have a direct and indirect impact on yield. Methods: 45 hybrids generated by crossing 10 diverse parents in structured mating design were evaluated to estimate the magnitude of their genetic variability and heritability in F2s. Mean performance across three replications were calculated for 21 traits and is assessed for their effect on yield. The recorded data were statistically analyzed at 5% level of significance by multivariate analysis using principal component and hierarchical cluster. Result: For all of the analyzed traits, the analysis of variance revealed a highly significant difference between population. A greater difference between PCV and GCV estimates for days to anthesis, days to 50% flowering and days to first picking indicates a greater degree of environmental control for these traits. Traits such as days to anthesis, days to 50% flowering and days to first picking shows low to moderate heritability. These findings show that there is enough genetic diversity in these parameters to support selection of better accessions. Using cluster analysis and principal component analysis (PCA), crosses were divided into groups based on their performance and the identification of the most discriminating attribute that accounted for the greatest variability. It revealed that yield per plant is highly associated with days to first picking, days to 50% flowering, days to anthesis, plant height and shoot length. Further, principal component shows 1000-seed weight and germination percentage followed by days to 50% flowering as the most discriminating trait. Hence, selection for any trait would favor future hybrids breeding programmes.","PeriodicalId":503872,"journal":{"name":"Agricultural Science Digest - A Research Journal","volume":"9 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140244424","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}

Nutrient management is an important approach for improving crop growth and productivity. Among all the nutrients, nitrogen helps in the overall growth of the plant. Nitrogen helps to synthesize chlorophyll and thereby supports building the protein units that enhance plant growth. As nitrogen is highly mobile, it is lost through different ways such as volatilization, leaching, nitrification, etc. Split application of nitrogen through proper scheduling is an important approach to reduce nitrogen loss as well as to improve nitrogen use efficiency. Hence, the investigation was conducted to find out how the scheduling of nitrogen is affecting pearl millet growth and productivity. Methods: The present study was conducted in kharif season of 2022 on pearl millet at Post Graduate Experimental Farm, M. S. Swaminathan School of Agriculture. The experiment was carried out in randomized complete block design with 3 replications and 9 treatments, namely, T1: control, T2: 50% basal RDN, T3: 100% basal RDN, T4: 50% basal RDN + 50% at 30 DAS, T5: 50% basal RDN + 25% at 30 DAS and 45 DAS, T6: 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 95%, T7: 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 90%, T8: 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 85%, T9: 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 80%. Result: The results showed that the application of 50% nitrogen as basal + topdressing @10 kg nitrogen/ha at sufficiency index less than 95% gave the maximum growth, yield, and income was also significantly higher with this application.

From GPS based soil survey and analysis by AICRP on Micronutrient, OUAT, Bhubaneswar, it was observed that boron deficiency was widespread in soils of Odisha (8-79%) and is a major constraint in light texture sandy loam soils under vegetable production. Growing of a shallow rooted crop like rice as direct crop followed by a deep-rooted vegetable crop can utilize leached Boron efficiently from subsoil thereby benefitting both rice and vegetable. Farmers in coastal Odisha generally grow knol-khol after rice and apply B frequently to both rice and knol-khol. Boron is one of the essential micronutrients required for the normal growth of knol-khol and plays an important role in yield of quality knobs. Till now no proper method and dose of boron is standardized for long term rice based vegetable cropping system regarding whether application of small dose every year is suitable or bulk quantity once or application in alternate years. Methods: A field experiment was conducted at E bock of Central Research Station, under AICRP on Micronutrient, O.U.A.T, Bhubaneswar to standardize the dose and frequency of boron application for rice-knol khol cropping system where boron is applied to first crop and knol-khol gets residual boron. In the present investigation residual effect of different graded doses of boron and its frequency of application on growth, yield, quality, post-harvest shelf life and economics of knol-khol for the year 2018-19 was studied. The experiment was laid out in a Factorial Randomized Block Design with three replications and four different doses of boron (0.5 kg ha-1, 1.0 kg ha-1, 1.5 kg ha-1 and 2.0 kg ha-1) at three different frequencies (application of boron once, alternate year and every year) were applied.

Better accessibility of formal seeds of fodder and green manure can ensure twin effects- productivity and sustainability. The present study throws the light in respect of the supply-demand gap of formal seeds, causes and seed replacement rates of fodder and green manure crops. Methods: The study was based on a survey conducted on a well-structured schedule during 2022 and 2023. Three stages of random sampling were adopted to select the Blocks, Villages and farmers. One bock with 06 villages and 60 farmers (10 farmers from each village) was selected randomly from each district for the study. So that study was comprised of a total of 05 blocks, 30 Villages and 300 farmers. Result: The study found that there was a gap in the supply-demand of formal seeds of fodder and green manure crops. The study further reported an inverse relationship between farm size and use of the formal seeds for fodder and green manure crops. The seed replacement rate (SRR) was less for all categories of farms. Farm size is negatively associated with seed replacement rate. Low SRR signifying the need to strengthen the seed supply systems. It was further observed the seeds from the informal sector were given less preference by formers, in terms of quality, over to formal seeds provided by public and private sectors. Despite this, the reason for the gap was that the formal seeds belonging to the public sector were not available in proper time and quantity. The availability of seeds of desired varieties through the public sector was also an issue of concern. Whereas, access to formal seeds belonging to the private sector was limited due to higher prices in comparison to the farmers’ saved seeds and formal seeds of the public sector causing a supply-demand gap for the fodder and green manure crops.","PeriodicalId":503872,"journal":{"name":"Agricultural Science Digest - A Research Journal","volume":"33 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140429464","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}
