Abstract:

Enhancing the nutrient use efficiency (NUE) in rice based food production systems of south konkan coastal zone of Maharashtra has always been an area of great focus as costs of production is increasing which ultimately results in reducing the productivity of the area and reduce the response of crop to recommended nutrient management. An experiment ‘On farm assessment of plant nutrients in rice –horse gram cropping systems’ were conducted during the year 2017–18 through farmer participatory approach in rice based food production systems of south konkan coastal zone of Ratnagiri district of Maharashtra. A total of 24 farmers in six different villages (four per village) of two blocks (Lanja and Rajapur) in area were selected. An experiment in farmers filed on rice–horse gram systems were conducted with various 7 treatments, viz., T1-Control, T2-Recommended N alone, T3-Recommended N and P, T4-Recommended N and K, T5-Recommended N, P and K, T6- Recommended NPK with ZnSO4 and T7-Farmers’ practice. Results reveled that across the six various villages of the zones and cropping systems, farmers applied lower level of N, P2O5, K2O and no amount of micronutrients as per recommendation. Application of recommended dose of NPK and micronutrient in every village in rice-horse gram system recorded higher system rice equivalent yield (REY kg/ha) over the farmer package, appropriate recommended NPK and micronutrients significantly boosted the yield. Improvement in agronomic efficiency (AE) of nitrogen, partial factor productivity of nitrogen and relative response was also reported at upper level with the combination of NPK+ Zn compared to N, NP and NK alone. Whereas in case of economics incremental benefits were recorded in net returns (rs/ha) and in benefit cost ratio (B: C ratio) at all the location.
