Abstract
A field experiment was conducted in Vertisols at Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya. Raipur (Chhattisgarh) to study the performance of rice straw management and nitrogen scheduling on yield and growth parameters of summer rice in Chhattisgarh plain. Results indicated that incorporation of rice straw 5 t ha-1 by MB plough once + disc harrowing twice fb irrigation at 30 DBT (T3) registered significantly highest grain and straw yields but it was at par to incorporation of rice straw 5 t ha-1 by + disc harrowing twice fb irrigation at 30 DBT (T2). Its harvest index (%) is non-significant and plant height, number of tillers, dry matter accumulation, number of leaves hill-1 and LAI was recorded significantly higher under treatment incorporation of rice straw 5 t ha-1 by MB plough once + disc harrowing twice fb irrigation at 30 DBT (T3) as compared to others. Although in number of tillers, dry matter accumulation, number of leaves hill-1 at par to treatments incorporation of rice straw 5 t ha-1 by + disc harrowing twice fb irrigation at 30 DBT (T2) and normal transplanting (T4) and along with in LAI was recorded at par to treatment incorporation of rice straw 5 t ha-1 by + disc harrowing twice fb irrigation at 30 DBT (T2). However among nitrogen scheduling, treatment 20% B +20% 15 DAT + 30% AT + 30% PI (N3) recorded significantly highest grain yield, straw yield and harvest index (%), plant height, number of tillers, dry matter accumulation, number of leaves hill-1 and LAI, but it was at par to 10% B +20% 15 DAT + 30% AT + 30% PI + 10% F (N4), although in grain yield, straw yield, dry matter accumulation, number of leaves hill-1 and LAI and in harvest Index (%) recoded at par to treatment 30% B + 10% 15 DAT+ 30% AT + 30% PI (N2) and 10% B +20% 15 DAT + 30% AT + 30% PI + 10% F (N4).
