“Effect of Fertilizers on Black Greengram in South Gujarat”

The study investigates the effects of organic manures, biofertilizers, and phosphorus on the growth, yield, quality, and soil nutrient status of black green gram. Bio compost applied at 2 t/ha (M2) significantly enhanced plant growth, yield, protein content, and nutrient uptake, along with the highest seed (909.00 kg/ha) and Stover (1771.56 kg/ha) yields. PSB inoculation (B1) improved growth attributes, seed yield (830.36 kg/ha), and nutrient uptake, while phosphorus application at 40 kg/ha (P2) resulted in superior growth, yield, and protein content. The combination of bio compost, PSB inoculation, and phosphorus (M2B1P2) delivered the highest net return (45851 /ha) and BCR (3.37). Organic manures and biofertilizers enhanced soil nutrient status, with bio compost improving N and P, while PSB inoculation increased available P.
