Abstract:
The faulty agricultural practices create the problem likes degradation of natural resources, only one way to out come these problem uses the conservation agriculture practices. The slow growth of pigeon pea during initial phase of growth that minimizes competition in intercropping systems that create pigeon pea well-suited with most cereal-based systems. This experiment was conducted at TCA research farm, Dholi (Dr. RPCAU, Pusa) during 2019-2020. To find out the effect on permanent bed and zero tillage practices on pigeon pea in maize-pigeon pea intercropping system. The experiment was led out in split plot design with 4 main plot treatments viz., T₁: Permanent bed (PB), T₂: Zero tillage (ZT), T₃: Fresh bed (FB) and T₄: Conventional tillage (CT) and 3 sub-plot treatments 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 pigeon pea affected by tillage and nutrient management. The plant height, primary and secondary branches of pigeon pea 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 pigeon pea viz., number of pods per plant, number of grains per pod and test weight. Pigeon pea was recorded higher grain yield with PB (21.8 q/ha) remained superior to its yields under ZT (19.5 q/ha) FB (18.2 q/ha) and CT (18.0 q/ha) practices while, under the nutrient management practices recorded highest yield with 120% RDF application in pigeon pea (21.1 q/ha) which was over the 100% RDF application in both crops. Harvest index of both crops were higher in PB and 120% RDF applications which was closely followed by ZT and 100% RDF application.
