Abstract:
The experiment was carried out during Kharif season 2019-20 at Crop Research Farm, SHIATS Model of Organic Farm (SMOF), Department of Agronomy, NAI, SHUATS, Prayagraj (U.P.) to study the “Response of Black rice (Oryza sativa L.) varieties to organic production technology”. Considering T10Kalabhat, Vermicompost (2.25 t/ha) and Jeevamrutha (500 l/ha), performed significantly higher in No. of tillers/hill (21.93), straw yield (26.57t/ha) and Fertility ratio (91.98%). Considering T15 Manipuri black, Vermicompost (2.25 t/ha) and Jeevamrutha (500 l/ha) performed significantly higher in days taken to panicle emergence [50%] (74.66 days), physiological maturity (117.33 days), grain yield (5.61 t/ha), grain protein (15.60%), also maximum Gross return (7,22,633.3₹/ha), Net return (6,29,013.3₹/ha) and B:C ratio (1:6.7). It can be concluded from the below research that application of Vermicompost (2.25 t/ha) and Jeevamrutha (500 l/ha) found to be enhancing productivity and economy of organic Manipuri black rice. Also it is a very good and sustainable cultivation practice.
