Effect of Molybdenum and Sulphur on Yield and Economics of Summer Black gram (Vigna mungo L.)

A field experiment was conducted at the Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.), during the month of Zaid 2022. To study treatments consisting of three levels of Molybdenum viz. Mo 1 kg, 1.5 kg and 2 kg/ha and three levels of Sulphur viz. 10, 20 and 30 kg/ha. The soil on the experimental plot was sandy loam in texture, had a pH of 7.1, contained 0.28 per cent organic carbon, and had 225 kg of nitrogen, 19.50 kg of phosphorus, and 92 kg of potassium available per hectare. There were 10 treatments, each reproduced three times, and they were organised using a random block design. The outcomes showed that treatment 9 (Molybdenum 2 kg/ha + Sulphur 30 kg/ha) significantly increased the number of pods/plant (27.6), the number of seeds/pod (9.53), seed yield (1.25 t/ha), Stover yield (2.87), harvest index (30.3%), gross returns (87500.00), net returns (47281.52)and B:C ratio (1.18) in comparison to alternative treatments.
