Effect of system of rice intensification on yield attributes towards enhancement of grain yield in rice

Abstract

The experiments revealed that effect of age old seedling, spacing, weed management by conoweeder, chemical weeding, manual weeding, nutrient management with organic and inorganic fertilizer and alternate wetting and drying on the yield attributes, (number of panicle m-2, number of grain panicle), was favourably influenced by SRI (use of 8-12 days old seedling, 25x25 cm of spacing, saturation of water, four times conoweeding only with inorganic) in both the cropping seasons. Subsequent high yield is obtained from SRI (use of 8-12 days old seedling, 25x25cm of spacing, four times of conoweeding, saturation water, use of 75% inorganic+ 25% organic). The least grain yield and straw yield was recorded in conventional method of transplanting.
