Nutrient management through organic source in summer green gram (Vigna Radiate L.)

Abstract

The field experiment experiment was conducted at Agricultural Research Station for Irrigated crops, Anand Agricultural University, Thasra, Dist.: Kheda, Gujarat to study the effect of Nutrient management through organic source in summer green gram (Vigna Radiate L.). The field trial was laid out in Random Block Design with ten treatments viz., No manure (Control) (T1), FYM 4.0 t/ ha (T2), Vermicompost 1.0 t /ha (T3), Castor cake 0.5 t/ha (T4), Bio NP (Rhizobium & PSB 1 L/ha) (T5), FYM 2.0 t/ ha + (Rhizobium & PSB 1 L/ha) (T6), Vermicompost 0.5 t /ha + Bio NP (Rhizobium & PSB 1 L/ha) (T7), Castor cake 0.25 t/ha + Bio NP (Rhizobium & PSB 1 L/ha) (T8), FYM 2.0 t/ ha + Vermicompost 0.5 t /ha (T9) and FYM 2.0 t/ ha + Castor cake 0.25 t/ha (T10). Treatment T9 (FYM 2.0 t/ ha + Vermicompost 0.5 t /ha) recorded significantly higher grain yield (1632 kg/ha) but was at par with treatment T6 (FYM 2.0 t/ ha + Bio NP (Rhizobium & PSB 1 L/ha) and treatment T7 (Vermicompost @ 0.5 t /ha + Bio NP (Rhizobium & PSB 1 L/ha)) than rest of the treatments. However, grain quality parameter viz. Protein content (24.73 %) also higher in the treatment T9 (FYM 2.0 t/ ha + Vermicompost 0.5 t /ha). The economics of various treatments showed that treatment T9 (FYM 2.0 t/ ha + Vermicompost 0.5 t /ha) gave the highest net return of Rs 90727 per hectare with CBR 3.92.
