Effect of organic nutrient management on growth rate and crop productivity in sustainable rice-rice system
Abstract: A field experiment was carried out at Bhubaneswar during 2013-14. The soil of the experimental site was sandy loam in texture with 6.35 pH. Rice-rice sequence was taken for six consecutive years with seven organic nutrientrnmanagement treatments in Randomized Block Design. Organic nutrient management expressed significant effect on DM (dry matter accumulation), CGR (Crop growth rate), RGR (Relative Growth Rate) crop yield andrnproductivity. DM, CGR, RGR were highest in treatment T receiving Dhanicha+ FYM+Vermicompost in kharif 5 and FYM+Vermicompost in summer (75.99 and 75.80 g hill-1 DM). Maximum average grain yield of 4.47 and 4.26 t ha-1 were also witnessed in T5 during kharif and summer seasons respectively.
