Author(s): RG Goswami and RK Bajpai
Abstract: A field experiment was conducted on a deep black clay loam (Vertisols) soil at research cum Instructional farm, Department of Soil Science and Agril. Chemistry, IGKV, Raipur (C.G) during Summer seasons, 2017 to study the Effect of nutrient management and rice establishment on Root CEC of rice under normal & delay planting condition during Summer. The experiment comprises various nutrient management as different source of N fertilizers and rice establishment method laid out in Strip plot design with four replications. The details of the treatments were; four level of nutrient management, seven level of rice establishment and two level of planting time. The result of the experiment revealed that, Root CEC at 30 DAT of T1N3-MBDS(L) + USG (42.75 meq 100-1g) which was statistically higher than all other interaction and T7N4-SRI + Neem cake coated urea (20.75 meq 100-1g) had the minimum Root CEC at 0-20 and 20-40 cm depth respectively under Summer- NP and highest in T1N3-MBDS (L)+ USG (50.00 meq 100-1g) and lowest in T2N1- MBDS (S) + Control (23 meq 100-1g) & T5N1- FRBT(M) + Control (21 meq 100-1g) at 0-20 and 20-40 cm depth respectively under DP. Similarly the higher Root CEC was found in T5N3-FRBT (M) + USG (45.50 meq 100-1g) under NP and minimum under T2N1-MBDS (S) + Control (23.75 meq 100-1g) under DP at 0-20 depth respectively at stage of maximum flowering. It was also reported that Root CEC was positively significantly influence by the interaction of (establishment method x nutrient management) under 0-20 and 20-40 cm depth at 30 DAT and maximum flowering condition under both i.e. normal and delay planting condition.
