EFFECT OF NITROGEN LEVELS ON YIELD AND ECONOMICS OF BASMATI RICE VARIETIESUDAY, RAJESH SINGH AND WASIM KHAN
A field experiment was conducted during kharif season (2020) at Crop Research Farm, Department of Agronomy, SHUATS, Allahabad (U.P.). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.28 %), available N (225 kg/ha), available P (19.50 kg/ha) and available K (213.7 kg/ha). The Treatments consisted of 3 levels of Nitrogen N1 (90 kg/ha), N2 (100 kg/ha), N3 (110 kg/ha) and 3 different varieties (Basmati 1121), (Basmati 1718) and (Pusa basmati -1). The experiment was laid out in Randomized Block Design with 9 treatments and replicated thrice. The results revealed that the application of Nitrogen 110 kg/ha + basmati 1121 recorded maximum plant height (73.00 cm), Number of tillers/hill (15.20), plant dry weight (22.14 g/hill), panicle length (31.93 cm), number of panicle per meter (565.90), number of panicle per hill (9.80), number of filled grains per panicle (141.90), number of grains per panicle (197.20), test weight (29.30), grain yield (2.56 t/ha), straw yield (4.78 t/ha) and harvest index was found to be non-significant. Maximum Gross retunes (125722 INR/ha), Net retunes (59522.10 INR/ha) and B:C ratio (1.76) were also recorded with the treatment with the application of Nitrogen 110 kg/ha + basmati 1121.
