Effect of Nitrogen Levels and Planting Methods on Growth and Yield of Black Rice (Oryza sativa L.)

Abstract

Background: Compared to other types of rice, black rice  has the highest protein content vitamins and minerals. Black rice contains essential amino acids like lysine, tryptophan; vitamins such as vitamin B1, vitamin B2, folic acid; and it is a good source of minerals including iron, zinc, calcium, phosphorus and selenium. Objectives: Impact of nitrogen levels and planting methods on black rice growth and production. Methods:  A field experiment was conducted during kharif season of 2021, at crop research farm of Department of Agronomy at Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj in North Eastern plains of Eastern Uttar Pradesh. under randomized block design comprising of 9 treatments of which treatments (T1-T9) with different combination of nitrogen along with different planting meathods which are replicated thrice. Conclusion: The treatment Nitrogen at 75 kg/ha nitrogen + SRI  method recorded maximum. Plant height (118.13 cm), number of tillers/hill (11.00), plant dry weight (31.62 g/plant), number of panicles per hill (10.83), number of grains per panicle (196.70), number of filled grains per panicle (116.33), grain yield (4.61 t/ha) and straw yield (11.38 t/ha). Because the findings are based on research conducted during a single season, they may be repeated for further confirmation.
