Abstract:
A field experiment was conducted during zaid 2021 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 7.4), low in organic carbon (0.32%), available N (188.3 kg/ha), available P (34.5 kg/ha) and available K (87.5 kg/ha). The experiment was laid out in Randomized Block Design with Twelve treatments each replicated thrice on the basis of one year of experimentation. The treatments which are T1 - Control (No sulphur + No iron), T2 - No sulphur + 0.5% FeSO4 Foliar spray at 25 DAS and 45 DAS, T3 - No sulphur + 25 kg/ha FeSO4 as basal dose application, T4 - 20 kg/ha Sulphur as gypsum + 20 kg/ha Sulphur as single super phosphate + 0.5% FeSO4 Foliar spray at 25 DAS and 45 DAS, T5 - 20 kg/ha Sulphur as gypsum + 20 kg/ha Sulphur as single super phosphate + 25 kg/ha FeSO4 as basal dose application, T6 - 20 kg/ha Sulphur as gypsum + 20 kg/ha Sulphur as single super phosphate + No (0) FeSO4 (Distilled water spraying), T7 - 40 kg/ha Sulphur as single super phosphate + 0.5% FeSO4 Foliar spray at 25 DAS and 45 DAS, T8 - 40 kg/ha Sulphur as single super phosphate + 25 kg/ha FeSO4 as basal dose application, T9 - 40 kg/ha Sulphur as single super phosphate + No (0) FeSO4 (Distilled water spraying), T10 - 40 kg/ha Sulphur as gypsum + 0.5% FeSO4 Foliar spray at 25 DAS and 45 DAS, T11 - 40 kg/ha Sulphur as gypsum + 25 kg/ha FeSO4 as basal dose application and T12 - 40 kg/ha Sulphur as gypsum + No (0) FeSO4 (Distilled water spraying) used. The results showed that application of 20 kg/ha Sulphur as gypsum + 20 kg/ha Sulphur as single super phosphate + 25 kg/ha FeSO4 as basal dose application recorded significantly higher plant height (48.53 cm), number of nodules per plant (30.16), number of branches per plant (5.93), plant dry weight (10.69 g/plant), pods per plant (36.07), seeds per pod (12.07), seed yield (1421.00 kg/ha), stover yield (3306.00 kg/ha) and harvest index (30.06%) as compared to other treatments.
