Effect of Spacing on Yield and Economics of Varieties of Black Gram (Vigna mungo L.)

A field experiment was conducted during Zaid 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) to study about the Effect of Spacing on Yield and Economics of Varieties of black gram. 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 each replicated thrice by keeping three Spacing and Varieties levels, the treatments which are T1: 25 cm x 20 cm + SHEKHAR 2 Variety, T2: 25 cm x 20 cm + PANT U-35 Variety, T3: 25 cm x 20 cm + T9 Variety, T4: 30 cm x 15 cm + SHEKHAR 2 Variety, T5: 30 cm x 15 cm + PANT U-35 Variety, T6: 30 cm x 15 cm + T9 Variety, T7: 45 cm x 10 cm + SHEKHAR 2 Variety, T8: 45 cm x 10 cm + PANT U-35 Variety, T9: 45 cm x 10 cm + T9 Variety used. The results showed that spacing of 45 cm x 10 cm + SHEKHAR 2 Variety was recorded significantly pods/plant (64.64), Seeds/pod (8.20), Test weight (38.50 g) whereas maximum crop growth rate (4.36 g/m2/day) was recorded with treatment with Spacing of 30 cm x 15 cm + T9 Variety. However, higher Seed yield (1062.86 kg/ha), gross returns (Rs. 63771.6/ha), net return (Rs. 39866.95/ha) and benefit cost ratio (1.66) were obtained with application of 30 cm x 15 cm + SHEKHAR 2 Variety as compared to other treatments. Therefore, I concluded that spacing of 30cm x 15cm + SHEKHAR 2 Variety was produced more grains and economic effective.
