Seed bio-priming of green gram with Rhizobium and levels of nitrogen and sulphur fertilization under sustainable agriculture

The experiment waslaid out in a factorial randomized block design comprising eighteen treatment combinationsof three levels of N (0, 10 and 20 kg ha⁻¹), three levels of S (0, 10 and 20 kg ha⁻¹) and two levels of biofertilizer (seed bio-priming and without Rhizobium) which were replicated three times. The results indicated that plot with the application of N and S @ 20 kg ha⁻¹ gave significantly (p< 0.05) higher seed yield (∼ 32 and 21%) and stover yield (∼ 16 and 18%) as compared to control plot, respectively. Bio-primed observed significantly (p < 0.05) higher seed yield (∼ 996 kg ha⁻¹) and stover yield (∼ 1829 kg ha⁻¹) ascompared to un-inoculated treatments. Mean while, plot with the applicationof N and S @ 20kgha⁻¹+ bio-priming @ 25 g kg⁻¹ seeds on loamys and soil resulted the increased the seed yield ∼ 32, 21 and7%, respectively and nutrients availability besides organic carbon (5, 2 and 2.3%), available N (5, 4.5 and 4.6%), P₂O₅ (7.5, 2 and 0.5%), and S (12, 22 and 11%, respectively) concentration increased in soil after harvest of green gram under bio-primed treatments.
