Effect of timing of vermicompost application and different level of NPK on growth, yield attributing characters and yield of rice in rice-wheat cropping system

Abstract

Two field experiments were conducted during 2011-12 and 2012-13 in the Crop Research Centre, of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, Uttar Pradesh taking rice (PB-1) as a test crop. The maximum and significantly higher numbers of tillers per meter row length were recorded in T2 (100% NPK) followed by vermicompost with 75% N, 100% P and K before sowing. Maximum plant height was recorded with the application of 100% NPK. Recommended dose of NPK were significant in case of dry matter yield at maximum tillering and panicle initiation. Maximum grain yield during both the years was recorded with the application of 100% NPK (T2). Grain yield recorded under T2 differ significantly from T1, T9 and T10. Maximum straw yield was recorded in T2 followed by T1, T8, T9 and T10 during. Maximum biological yield found in T3.
