Effect of zinc and sulphur on growth and yield of rice (Oryza sativa L.)

Abstract

A field experiment was conducted at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) during Kharif, 2023. The soil of the experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), organic carbon (0.75%), available N (269.96 kg/ha), available P (33.10 kg/ha), and available K (336 kg/ha). The treatments applied were of zinc and sulphur. The experiment was laid out in Randomized Block Design with ten treatments each replicated thrice. Based on the objectives taken maximum plant height (117.14 cm), number of total tillers (5.02), days to 50 percent panicle emergence (57.33), days to maturity (97.33), plant dry weight (60.85 g/plant), effective tillers/m2 (392.54), panicle length (28.41 cm), grain yield/hill (28.63 g/hill), filled grains/panicle (252.45), grain yield (3.95 t/ha), straw yield (6.83 t/ha) were recorded significantly higher in treatment combination of 8 kg/ha zinc + 45 kg/ha Sulphur. Similarly, the maximum gross returns (₹ 123440.00/ha), net returns (₹ 83472.00/ha), and benefit: cost ratio (2.09) were recorded higher in treatment combination of 8 kg/ha zinc + 45 kg/ha Sulphur.
