Abstract:
Conservation agriculture is the effective way of utilization of natural resources and sustainable crop production. In CA practices we use in this experiment maize+pigeon pea intercropping that increase the crop intensification that lead to increase crop production. This experiment on “Effect of conservation tillage and nutrient management on maize in maize-pigeon pea intercropping system” was conducted during 2019-2020 at TCA research farm, Dholi (Dr. RPCAU, Pusa). The experiment was laid out in split plot design with 4 main plot treatment viz., T1: Permanent bed (PB), T2: Zero tillage (ZT), T3: Fresh bed (FB) and T4: Conventional tillage (CT) and 3 sub-plot treatment viz., N1: 100% Recommended dose of fertilizer (RDF), N2: 120% Recommended dose of fertilizer (RDF) and N3: 80% Recommended dose of fertilizer (RDF) which were replicated thrice. The result indicated that the parameters of growth, yield attributes and yield of maize crop was affected by tillage and nutrient management. The plant height and LAI of maize were significant influenced by tillage and nutrient management and it were higher in PB and 120% RDF application and it at par with ZT and 100% RDF application which were compared to CT and 80% RDF application. The higher growth under these treatments were also associated with yield attributing character of maize viz., length of cob, number of rows per cob, number of grains per row, test weight. Maize grown under PB tillage recorded (58.9 q/ha) of grain yield being at par with grown under ZT (56.4 q/ha) compared to CT (49.0 q/ha) while, under the nutrient management practices recorded highest yield with 120% RDF application in maize (58.1 q/ha). Harvest index of maize was higher in PB and 120% RDF applications which was closely followed by ZT and 100% RDF application.
