Abstract

A field experiment was carried out to test the effect of various organic sources of nutrients on growth and yield of summer greengram during summer 2011 at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar on loamy sand soil. Among the different organic sources, combined use of vermicompost+soil application of panchagavya at 15 and 30 DAS improved all yield attributes as well as recorded significantly higher seed yield over either sole application or conjuctive use of different organic sources in summer greengram except application of RDN through FYM + soil application of panchagavya at 15 and 30 DAS and RDF. It also improved seed yield to the tune of 18.43% over control (RDF). Soil health was improved with respect to drastic increase in microbial population as well as improvement in available nitrogen in the soil after harvest of crop by it over use of inorganic fertilizers alone i. e. RDF
