Nutrient content in greengram as influenced by greengram + sesame intercropping system

Abstract

The field experiment was conducted at Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna (M.P.) during the kharif season of 2017-18 and 2018-19 to study the effect of green gram + sesame intercropping system on the nutrient content in seed and straw of greengram. Nitrogen content in green gram seed was analysed significantly higher under sole crop of green gram over all intercropping system with a pooled average of 3.67%. Similarly, phosphorus and potassium content in seed of greengram was noted significantly more with 0.34% and 0.51%, respectively than that of intercropped treatment. Among the intercropping system, greengram + sesame (8:4 row ratio; 30 cm) and greengram + sesame (6:3 row ratio; 30 cm) treatment estimated significantly highest nitrogen content (3.61 and 3.35%), phosphorus content (0.34% and 0.33%) and potassium content (0.50% and 0.49%) in greengram seed, respectively. However, nitrogen, phosphorus and potassium content in green gram straw were recorded significantly higher under greengram + sesame with 8:4 row ratio; 30 cm (1.32, 0.23, 0.64%) followed by greengram + sesame of 6:3 row ratio; 30 cm (1.30, 0.22, 0.63%), respectively.
