Effect of Levels of Manures on Performance of Growth and Yield Parameters of Aerobic Rice Sahbhagi Dhan (IR-74371-71-1-CRR-1)

Abstract

An experiment has been conducted under field conditions at Organic Research Farm, Centurion University, Paralakhemundi, Gajapati, Odisha during Kharif season of 2019 to investigate the effect of two Organic Fertilizers (Vermicompost and Farm Yard Manure) on the performance of growth and yield parameters of aerobic rice, Sahbhagi dhan (IR-74371-71-1-CRR-1. The application of vermicompost and farm yard manure in absence and presence of Azotobacter results the maximum plant height (120 cm) and no. Of tillers/m² (162), no. Of panicles/m² (177) in 100% Vermicompost + Azotobacter (seed application) followed by 50 % Vermicompost + Azotobacter (Soil application). The maximum panicle length 25.6cm per m² was noticed with the 100% Vermicompost + Azotobacter (seed application). The treatment of 100% Vermicompost + Azotobacter (Seed application) had significantly maximum 1000 seed weight (24.2). The treatment of 100% Vermicompost + Azotobacter (seed application) produced significantly higher grain yield (19.26 quintal/ha) was recorded. The maximum straw yield was recorded with the 100% Vermicompost + Azotobacter (seed application) 12.95 quintal/ha.
