Maximization of groundnut (Arachis hypogaea L) yield by nutrient management practices

An experiment was conducted during kharif season of 2016 and 2017 at College of Agriculture, Gwalior. To optimise plant population and fertility levels an experiment was laid out in split plot design, replicated thrice in fixed plots and the test variety of the crop groundnut (Mallika) was used. The plant geometry of 30 × 10 cm, 25 × 10 cm and 20 × 10 cm was adopted with three fertility levels as 75, 100 and 125% recommended dose of fertilizers. The yield and economics were increased by optimization of plant geometry and nutrient management under kharif groundnut. Sowing of crop at 30×10 cm spacing resulted in 7.3 and 4.3 % higher pod yield over 25×10 cm and 20×10 cm spacing, respectively and 3.0 % higher haulm yield over 25×10 cm. Similarly, application of 125% RDF resulted in 3.0 and 9.3 % higher pod yield over 100% RDF and 75% RDF, respectively but application of 100% RDF resulted in 18.6% higher haulm yield over 75% RDF and was at par with 125 % RDF application. The highest gross, net returns and B:C ratio was obtained at the spacing of 30×10 cm with 125% RDF.

Arachis Hypogaea L

Background: Peanut (Arachis hypogaea L.) is one of the oil and cash crops in Vietnam. However, owing to the lack of appropriate management practices, the production and the area under cultivation of peanut have remained low. Mulches are the key factors contributing to promoting crop development and early harvest and increasing yields. Methods: The experiment consisted of three mulch treatments, viz., plastic mulch, straw mulch and no-mulch control. All the treatments were replicated thrice in a complete randomized block design. Result: In the conditions of mulch, the plant growth parameters (germination rate, growing time, plant height, number of branches per plant), leaf area index, the number of nodules per plant, dry matter accumulation, yield components and yield of peanut was much higher than that of no-mulch control. Among the mulches, plastic mulch was found superior to straw mulch in the pod yields and water-use efficiency and moisture conservation, thereby can be considered as a reliable practice for increasing the productivity of peanut on the coastal sandy land in Nghe An province, Vietnam.

Feed The Future

ABSTRACT New technologies combined with improved genetics and farmer access are important components required to improve productivity and efficiencies of cropping systems. The ability of the public and private sector to provide these components to farmers often vary considerably and can be challenging because of limited resource allocation and investment in institutions designed to provide these services. Partnerships among national programs where resources are limited and external entities can provide an effective platform to deliver improved cultivars and production and pest management practices that increase crop yield and economic viability of resource-poor farmers. In this note, we describe a partnership between the Council for Scientific and Industrial Research-Crops Research Institute (CSIR-CRI) in Ghana, the International Center for Research in the Semi-Arid Tropics (ICRISAT), the US Agency for International Development Peanut Collaborative Research Support Program (USAID Peanut CRSP), the Feed the Future Innovation Lab on Peanut Productivity and Mycotoxin Control (PMIL), and North Carolina State University (NCSU) that resulted in the release of two ICRISAT-derived lines as cultivars to farmers in Ghana. The cultivars Otuhia (Arachis hypogaea L.) and Yenyawoso (Arachis hypogaea L.) were released by CSIR-CRI in 2012 following evaluations of breeding lines beginning in 1999. This case study provides insight into the research focus and timeline that occurred with this partnership during the research and development process. A portion of the data obtained to support release of these cultivars is provided.
