Effect of Integrated Nutrient and Weed Management of French Bean (Phaseolus vulgaris L.)

Abstract

An experiment on “Effect of integrated nutrient and weed management of French bean (Phaseolus vulgaris L.)” was carried out during the 2018-19 and 2019-20 in Rabi season at the college research farm of T. D. Post Graduate College, Jaunpur, UP. The experiment was laid out in split plot design with five weed management treatments and four nutrient management treatments with three replications. Herbicides viz., pre-emergence (Pendimethalin) and post emergence (Quizalofop-ethyl & Imazethapyr) and two hand weeding at 20 and 40 DAS under weed management with an objective to study the effect of pre and post-emergence herbicides under integrated nutrient management on weed flora and their growth in French bean. This investigation recorded minimum weed density, weed dry weight and significantly higher results received that plant growth in terms of plant height (cm), number of branches plant-1, dry matter production plant-1, LAI, grain and straw yield and biological yield under two hand weeding (20 & 40 DAS) plots. Among the herbicide’s application, Imazethapyr @ 50 g a.i. ha-1 at 20 DAS was significantly superior to all the other herbicide application treatments and nutrient application was recorded with 100% RDF which was significantly superior to all the other nutrient management treatments during both the years of experimentation.
