Abstract
A field experiment was conducted at Organic Farming Research Centre, University of Agricultural and Horticultural Sciences, Navile, Shivamogga, Karnataka, India to study the Effect of of insitu green manuring on soil fertility, growth and yield of paddy under organic farming during kharif season of three consecutive years from 2013-14 to 2015-16. From the experiments it was found that the application of 100 kg N equivalent FYM for preceding dhaincha has produced higher green biomass yield of daincha (21035 t/ha) as compared remaining green manuring crops with or without manuring. Incorporation of preceeding manurings crop fertilized with 100 kg N equivalent FYM along with recommended dose of FYM (10 t ha-1) for succeeding rice crop has recorded significantly higher growth and yield attributes finally grain (50.49 q/ha) and straw yield (80.60 q/ha). The microbial population and final nutrient status of soil also found highest in the treatment which received 100 kg N equivalent FYM for daincha crop during sowing along with application of recommended dose of FYM for paddy (10 t ha-1) during incorporation of daincha. The continuous application of FYM along with green manure for four consecutive years has enhanced the soil chemical and biological properties.
