Abstract:
A STCR based field experiment on rice commenced in kharif 2017 at the Research Farm of Department of Soil Science and Agricultural Chemistry, JNKVV, Jabalpur with Integrated Plant Nutrition System (IPNS) approaches for assessing its impact on yield attributes and yield of rice in Vertisol. The field experiment layout was laid in four replications and six treatments viz., T₁: Control, T₂: GRD, T₃: T.Y. 50 q ha^-1, T₄: T.Y. q ha^-1, T₅: T.Y. 50 q with 5 t FYM ha^-1 and T₆: T.Y. 60 q with 5 t FYM in Randomized Block Design. The result revealed that growth, yield attributing characters and yield were significantly influenced by different treatments of nutrients application with and without FYM. Maximum plant height, number of tillers plant^-1, number of panicles and number of seed per panicle were obtained highest under T₆ having 158:107:69 kg N, P₂O₅ and K₂O + 5 t FYM ha^-1, while minimum with control. Yield of rice was significantly influenced by different treatments and highest grain (5678 kg ha^-1) and straw (7563 kg ha^-1) yields were recorded under T₆ having highest levels of NPK integrated with FYM. N, P and K content in shoot and roots of rice were observed in T_6, where minimum with control. Therefore, application of FYM with STCR based fertilizers increased the productivity of rice significantly under Vertisol of Madhya Pradesh.
