Association and Path Analysis of Yield and Its Component Traits for Yield Maximization in Green Gram: A Recent Study | Chapter 15 | Current Topics in Agricultural Sciences Vol. 8

In ten genetically diverse genotypes of green gramme (Vigna radiata L.) and their 24 F2 (segregating) populations, an analysis was done to determine the correlation coefficients among thirteen quantitative traits and to examine the direct and indirect effects of various yield contributing traits on grain yield. The results of the association study show that there is a highly significant and positive correlation between grain yield per plant and traits like number of days until flowering, number of pods per cluster, number of clusters per plant, number of pods per plant, and biological yield per plant (g), suggesting that these traits may be improved simultaneously. However, yield per plant for parents showed a significant negative correlation with primary branches per plant and harvest index at both the genotypic and phenotypic levels. The harvest index showed a negative connection with most of the features at both the genotypic and phenotypic levels. According to route analysis, biological yield per plant, harvest index, and seeds per pod all had a significant direct impact in the intended direction. Biological yield per plant, harvest index, seeds per pod, and clusters per plant may all be improved to maximise seed output per plant. High yielding cultivars can be created by using hybridization followed by direct and indirect selection for these features.

Case Studies on Promotion of Pulses through Seed Production among Farming Community | Chapter 03 | Current Topics in Agricultural Sciences Vol. 5

 The national government executed the NFSM "Creation of seed hubs for promoting indigenous production of pulses in India" in 2016-17 with the goal of increasing pulses production and per capita consumption among Indian farmers. The Krishi Vigyan Kendra (KVK) at Sirugamani, Tiruchirappalli district, is a pioneer knowledge resource centre, imparting the newest technology in agricultural crops, horticulture crops, and allied sectors to the Tiruchirappalli district farming community from seed to market. Tiruchirappalli promoted novel varieties including VBN 6 and VBN 8 in black gramme, CO 8 in green gramme, and CO (Rg) 7 in red gramme among farmers in Tiruchirappalli and adjacent districts as a seed hub centre, thanks to technical backstopping and interventions from KVK. From 2016 forward, farmers were encouraged to cultivate pure pulse crops through focus group talks, group meetings, field visits, off-campus trainings, and cluster frontline demonstrations. In the years 2017 and 2018, 72 farmers from the districts of Tiruchirappalli, Karur, Cuddalore, Perambalur, and Pudukkottai were registered to produce seeds under the Foundation stage I, Foundation stage II, and Certified stage. Farmers received a larger yield as a single crop than they did as a rice fallow pulse crop, with average net yields of Rs.75000/- per hectare. In the 2019-20 crop year, 95 farmers were registered to produce black gramme VBN 8 seed, indicating a growing trend in area and production. A young eager farmer experienced 832 kg per acre black gramme yield the same year. The rapid horizontal spread of black gramme seed production piqued the curiosity of a diverse range of farmers. Many successful farmers were able to achieve larger yields than their local counterparts. Farmers have produced 548 quintals of black gramme, 0.23 quintals of green gramme, and 4.81 quintals of red gramme through participatory farming. The value of cultivating pulses as a pure crop was pushed through mass media, newspapers, All India Radio and Doordharshan, TNAU agricultural magazine Uzhavarin Valarum Velanmai, exhibitions, campaigns, and trainings. Farmers in black gramme were able to achieve larger yields than local variety in two situations. Farmers have given positive feedback on the new varieties and the buy-back procurement policy used in this scheme. Under this initiative, a memorandum of understanding has been signed for the provision of seeds to the Department of Agriculture throughout Tamil Nadu.

Study on Standardization of Fermentation Time for Foxtail Millet to Blackgram | Chapter 5 | Cutting-edge Research in Agricultural Sciences Vol. 7

 Fermentation is a simple and cost-effective food processing system for preparing tasty and convenient foods. We tested instant or ready-to-use dosa mixes made from foxtail millet, rice, and pulses (black gramme and green gramme) fermented at 37°C for 6, 12, or 18 hours, depending on the pulse. Different combinations were created by combining these ingredients in different ratios, such as 70 percent foxtail millet, 20% black gramme, 10% green gramme, or 50 percent foxtail millet, 20% rice, 30% black gramme, and 10% green gramme, or 50 percent foxtail millet, 20 percent rice, 20% black gramme, 10% green gramme, and a control of 70 percent foxtail millet. The results revealed that for all combinations and controls, 12 hours of fermentation was needed to produce the best dosa. As compared to control, the first mixture produced better results, with percentage increases in appearance, texture, flavour, and overall acceptance of 3.66 percent, 2.41 percent, 1.18 percent, and 1.19 percent, respectively, with a 7.53 percent decrease in taste and no difference in sourness for both samples.

Agroforestry Practices among Farmers in Igabi Local Government Area of Kaduna State, Nigeria | Chapter 3 | Cutting-edge Research in Agricultural Sciences Vol. 7

 Farmers in the Igabi Local Government Area of Kaduna State, Nigeria, were interviewed about their agroforestry activities. A standardised questionnaire was used to collect data from 100 randomly selected farmers. The farmers' socioeconomic characteristics, degree of understanding and adoption of agroforestry practises, types of agroforestry practises adopted, factors influencing farmers' willingness to adopt agroforestry practises, common tree species retained on the field, and constraints faced by farmers in adopting agroforestry-based farming were all covered in the questionnaire. The frequency, percentage, mean, and probit model were used to analyse the data. The research discovered that males (78.00%) dominated farming activities in the study field, that the majority (96.00%) of the farmers are between the ages of 21 and 60, that the majority (87.00%) of the farmers are skilled, and that the majority (76.00%) of them have more than 5 years of farming experience. Farmers in the study region were aware of and practising various forms of agroforestry systems, including tree retention on the farm (33.00 percent), tree planting along with the retained trees (28.00 percent), taungya farming system (28.00 percent), and alley farming (28.00 percent) (20.00 percent ). The study found that agroforestry methods are widely used (79.00 percent) in the study areas. The most widely used agroforestry method in the study region was tree retention on farmland (31.0%), while shifting cultivation was the least widely used (5.00%). The probit model analysis revealed that farm size (1.1122), farming experience (0.0231), and access to credit (0.1103) were the variables that significantly influenced farmers' willingness to adopt agroforestry practises in the study region at the 10.00 percent probability level. The study also found that Parkia biglobosa and Vitellaria paradoxa were the two tree species most commonly retained on farmland by all respondents (100%), while Eucalyptus camadulensis was the least commonly grown or retained tree species on farmland in the study region (12.00%). However, constraints such as the high capital intensive nature of agroforestry practises (87.00 percent), weak extension service (80.00 percent), insufficient capital (77.00 percent), poor technical know-how of agroforestry practises (45.00 percent), land tenure system (36.00 percent), and lack of access to credit hindered the degree of adoption of agroforestry practises in the study region (13.00 percent ). Improved agroforestry extension services should be provided to farmers in the study region, according to the study; workshops, seminars, and symposia should be organised for adequate training of farmers to understand agroforestry techniques; and farmers should be encouraged to form cooperative societies so that they can have access to resources.
