Impact of Fertilization of Sulphur and Iron on Yield Attributes and Economics of Greengram (Vigna radiata L.)

At Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj, UP (India), a field experimentation was undertaken in zaid 2021. The experimental plot's soil texture was sandy loam. At the same time pH, low organic carbon, available N, available P and available K were (7.4), (0.32%), (188.3 kg/ha), (34.5 kg/ha) and (87.5 kg/ha) respectively. The experiment was set up in a Randomized Block Design (RBD) with 12 treatments and three replica. The results showed that treatment 5 with application of 20kg/ha Sulphur as Gypsum + 20kg/ha Sulphur as Single Super Phosphate + 25kg/ha FeSO4 as basal dose application was recorded maximum no. of pods per plant (36.07), no. of seeds per pod (12.07), test weight (37.03 g), seed yield (1421.00 kg/ha), stover yield (3306.00 kg/ha), harvest index (30.06%), gross return (1,31,196.00 INR/ha), net return (87,806.00 INR/ha) and benefit cost ratio (2.02) as compared to other treatments.
