Effect of Sulphur on Growth and Yield of Rice (Oryza sativa L.) Varieties

Abstract

The field experiment was conducted during kharif 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36 %), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The experiment was laid out in Randomized Block Design with nine treatments, replicated thrice. The treatments consists of T1: MTU – 7029 + Sulphur 10Kg/ha, T2: MTU – 7029 + Sulphur 20Kg/ha, T3: MTU – 7029 + Sulphur 30Kg/ha, T4: BPT – 5204 + Sulphur 10Kg/ha, T5: BPT – 5204+ Sulphur 20Kg/ha, T6: BPT – 5204 + Sulphur 30Kg/ha, T7: ARIZE – 6444 + Sulphur 10Kg/ha, T8: ARIZE – 6444 + Sulphur 20Kg/ha, T9: ARIZE – 6444 + Sulphur 30kg/ha are used. The results showed that application of BPT – 5204 + Sulphur 30kg/ha, recorded significantly higher plant height (111.20 cm), number of tillers/plant (11.45), plant dry weight (53.07 g/plant), Crop Growth rate (16.07 g/m2/day) panicles/plant (17.00), number of grains per hill, panicle (100.69), Test weight (21.51 g), panicle length (20.20 cm), grain yield (5.62 t/ha), Straw yield (9.68 t/ha), Harvest index (36.72%) were recorded with the treatment of BPT – 5204 + Sulphur 30 kg/ha. The higher gross returns (Rs. 1,72.050.00/ha), net return (Rs. 1,12,790.00/ha) and benefit cost ratio (1.90) was obtained in the treatment of BPT – 5204 + Sulphur 30 Kg/ha.
