Abstract:
The experiment was conducted during Kharif season 2021, at Crop Research Farm, Department of Agricultural Sciences, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj (U.P.). The soil of the experimental plot was sandy loam in texture, nearly natural in soil reaction (pH 7.6), low in organic content (0.51), low in available N (230 kg/ha), medium in available P (17.80 Kg/ha) and medium in available K (245.10 kg/ha). The objective was to study Effect of varieties and organic manure on growth and yield of Black Rice (Oryza sativa L.) under Randomized block design comprising of 3 replications and 9 treatments (Conventional Transplanting of Rice). The Treatment consistant of 3 organic manures (FYM, Poultry manure and Vermicompost) and 3 different varieties (Chakhao Poreiton), (Chakhao Amubi) and (SKM 111). The experimental results revealed that with black rice cultivars along with Chakhao Poireiton + 50% N through Poultry manure + 50% N through FYM (T₃) recorded highest numbers of tillers/hill (10.20), Plant Dry weight (32.32g), Crop Growth Rate (12.46 g/m/day), Relative Growth Rate (0.014g/g/day), number of panicle/hill (10.00), numbers of grains per panicles (206.70), numbers of filled grains per panicles (83.20), grain yield (4.36 t/ha), straw yield (10.15 t/ha) were recorded highest among other treatments. Chakhao Poireiton + 50% N through Poultry manure + 50% N through Vermicompost was recorded in highest test weight (24.57 g). It is clearly concluded that from the research T₃: Chakhao Poireiton + 50% N through Poultry manure + 50% N through FYM significantly produce more yield and recommended for eastern U.P condition.
