Impact of Biovita on Growth, Yield and Economics of Rice
Abstract
Abstract
An experiment was carried out during Kharif 2013 and 2014 in deep black soil to study the Impact of biovita on growth, yield and economics of rice (Oryza sativa L) at ARS, Dhadesugr, University of Agricultural Sciences, Raichur, Karnataka. Pooled data revealed that, panicle length was not significantly influenced by different rate of biovita application. However, Significantly higher grain yield (6491 kg/ha) and straw yield (7787 kg/ha) were recorded in the treatment applied with biovita granule at 12.5 kg within 10 days after transplanting + first spray of biovita liquid at 500 ml at tillering (30 DAP) + second spray of biovita liquid at 750 ml at panicle initiation (60 DAP) + third spray of biovita liquid at 750 ml at grain filling stage (75 DAP) and which was onpar with the application of biovita granule at 10.0 kg within 10 days after transplanting + first spray of biovita liquid at 500 ml at tillering (30 DAP) + second spray of biovita liquid at 750 ml at panicle initiation (60 DAP) + third spray of biovita at 750 ml at grain filling stage (6339 kg/ha and 7586 kg/ha, respectively) and application of biovita granule at 7.5 kg within 10 days after transplanting + first spray of biovita liquid at 500 ml at tillering (30 DAP) + second spray of biovita liquid at 750 ml at panicle initiation (60 DAP) + third spray of biovita liquid at 750 ml at grain filling stage (5913 kg/ha and 7376 kg/ha, respectively). Whereas, application of only recommended dose of fertilizer recorded significantly lower grain yield (5087 kg/ha) and straw yield (6050 kg/ha) compared to other treatments.
