Effect of phosphate rich organic manure on growth, yield and quality of greengram (Vigna radiata L.)

A field investigation entitled “Effect of phosphate rich organic manure (PROM) on growth, yield and quality of greengram” was conducted in kharif season of 2024- 2025 at Post Graduate Institute, Mahatma Phule Krishi Vidyapeeth, Rahuri. The experiment was conducted in randomized block design with seven treatments replicated 3 times. Results revealed that treatment T₃ (100% P2O5 through SSP) recorded significantly higher all the growth contributing characters viz., plant height (56.99 cm), no. of functional leaves plant^-1 (11.46), leaf area plant^-1 (10.62 dm²), no. of root nodules plant^-1 (28.33) and dry matter plant^-1 (24.33 g). Similarly, all the yield contributing characters no. of pods plant^-1 (27.25), no. of seeds pod^-1 (10.61), wt. of pods plant^-1 (13.31 g), wt. of seeds plant^-1 (12.89 g) and 1000 seed weight (42.31 g) were recorded significantly maximum under T₃ treatment (100% P2O5 through SSP). The highest grain yield (1323 kg ha^-1), straw yield (1996 kg ha^-1), biological yield (3319 kg ha^-1), harvest index (39.86%) is also recorded by the T₃ treatment (100% P2O5 through SSP).
