Trichoderma viride is a promising biocontrol agent against major soil-borne plant pathogens like Macrophomina, Fusarium, Sclerotium, and Rhizoctonia sps, which are causing significant crop losses ranging from 25 to 45 percent. The availability of viable spore inoculum under farm-level conditions is a significant constraint for the effective management of soil-borne diseases. In addition to recycling crop residues to enhance soil health, there is an emerging need for crop cultivation. To explore the substrate for on-farm production of T. viride, an investigation was made into the effectiveness of maize shank for on-farm multiplication. The studies on the spawning technique for multiplication of T. viride using different sizes of shank such as 0.5, 1, 2, 4, 6, 8, 10 cm and powdered form of shank revealed that the powdered shank inoculated with talc formulation (20 x 106 cfu/g) of T. viride @ 10 gram in 200g shank-based spawn with 40 % moistened was found to be effective for the colonization of T. viride 28 days after inoculation.
Images of ten rice genotypes consisting of Chithrakar, Kuliyadichan, TRY 4, ADT 53, ACK 14090, ACK 15004, ADT 45, ASD 19, IR 64, Bhavani were selected and subjected to various image processing machine learning tool for vision based classification. Using Grain analyzer, morphological features of rice seed such as length, breadth, thickness, geometric mean diameter, sphericity, surface area, weight and area were estimated. The mean data were subjected to PCA analysis in STAR software to reduce the dimensionality. The trait such as length, surface area, geometric mean diameter, area and weight contributed significant variation as they possessed positive values in both PC1 and PC 2. The predicted variables of PCA and visual, textural, spectral characteristics of rice seed image obtained from Image Analyser (LEICA) were subjected to various image processing process. The processed images were fed into the machine tools viz., Partial Least Square Regression (PLS) and Support Vector Machine (SVM) for vision based classification. Totally 2000 images were taken and 80 per cent images were used for training the model, 20 per cent images were kept for testing the model. By comparing accuracy, precision, recall and F1 score of both the methods, PLS gives better performance than the SVM classifier. By using these classifiers, genotypes could be identified based on morphological features, visual characteristics and textural characteristics, as the accuracy and prediction are reliable.
Prolonged flash floods in South and Southeast Asia cause substantial crop yield reductions, but improved breeding techniques enhance resilience. The F2 population derived from the cross between ASD 16 and the NIL of CO 51 Sub1 was evaluated to study genetic variability, trait associations, and direct/indirect effects on yield. The Indel marker ART 5 revealed distinct segregation patterns in progenies (Homozygous:22; Heterozygous:72). The investigation unveiled high PCV, GCV and heritability, accompanied by high genetic advances, in pivotal traits such as the number of productive tillers per plant, flag leaf length, number of filled grains per panicle, number of chaffy grains per panicle, and single plant yield. These findings indicate the prevalence of additive genetic effects and underscore the substantial contributions of these traits to the observed variability within the population. The results of the correlation analysis indicated a highly significant positive correlation between single plant yield and four important traits: days to fifty percent flowering, plant height, panicle length, and number of filled grains per panicle. The path coefficient analysis indicated that the number of productive tillers per plant exerted the most substantial positive direct influence on the single plant yield. Similarly, spikelet fertility, number of chaffy grains per panicle, and plant height demonstrated significant positive effects as well. The findings indicate that the selection of specific traits viz., plant height, panicle length, number of filled grains per panicle and number of productive tillers per plant can enhance breeding outcomes.
Farmer Producer Organizations (FPOs) emerge as the near gateways for the small and marginal farmers of India. A Farmer Producer Organization represents the power of aggregation; many small farmers come together and form an organization that collectively purchases inputs required by them and/or sell their produce. Initially, only small informal groups of farmers are formed and gradually such farmer interest groups or FIGs are, then registered under the Company Act or Cooperative Societies and which ultimately turn or form into FPOs. A study on the dynamics of farmer Producer Organization in Manipur shows that the FPOs have been reformed from the various Farmer Interest Groups (FIGs), Self Help Groups (SHGs), Joint Liabilities Groups (JLGs) and Farmers’ Clubs (FCs) that was formed by the KVK and other rural development agencies in to formal organizations which are ultimately registered under the Company Act, 2013. Altogether, 195 groups from SHGs, JLGs and FCs are categorized into 3 clusters, pooled and formed the 3 FPOs as the Dairy-based, Poultry-based and Piggery-based Agro-Farmers Producer Company Limited by the Krishi Vigyan Kendra, Imphal West and taken under the formation, promotion and handholding mechanism of clustering small, marginal and landless farmers of the district. The group dynamics and governance of FPOs shows that the companies have elected Board of Directors (BODs) including 5 women BODs. Director Identification Number (DIN), Tax Deduction and Collection Account Numbers (TAN) and Permanent Account Number (PAN) for the BODs and the companies are created and they conduct regular board meeting and annual general body meeting too. It is also found that the 3 AFPC Ltd. conduct share mobilization, capacity building programmes of BODs and shareholders, financial literacy programmes and even the statuary company compliances too. Investigation on the Good/Best FPOs Practices followed by the Producer Organization Promoting Institute (POPI) shows that the promoting institute i.e the ICAR-Krishi Vigyan Kendra, Imphal west is also best in its business. Practices such as the innovation in mobilization of members, convergence, governance and business development along with share & care technique are followed by the POPI. A thorough investigation and analysis of the various problems and constraints perceived by FPOs stakeholders also some challenges such as the “Promotion & Handholding, Sustainability and Institutional issues in the formation, promotion and handholding of farmer Producer Organization in Manipur.
The present study was conducted at Kokowal, Majari, Jhunewal and Bhadiar sites located in Hoshiarpur district of Punjab, Northern India. The soil samples were collected from upper, middle and lower slope positions of each site and analysed for soil physical properties. Significantly higher soil organic carbon (SOC) was observed in Bhadiar compared to all other locations. The average SOC increased significantly with the lower slope positions. Among all the sites, the significantly lowest mean value of bulk density was observed at Kokowal (1.45 Mg/m3) and highest at Jhunewal (1.48 Mg/m3). Saturated hydraulic conductivity was significantly low on lower slope position than upper slope position irrespective of soil depth at all sites. At lower slope position significantly less infiltration rate was observed over the upper slope position. Soil moisture retention varied from 12.0 to 16.2, 14.7 to 16.9 and 16.3 to 17.9 percent for upper, middle and lower slope position respectively. The moisture content of soil profile increased with increase in soil depth irrespective of slope position. The total moisture storage was 20.0, 23.1 and 24.9 cm on upper, middle and lower slope position respectively.
