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

Abstract

The experiment was laid out in a factorial randomized block design comprising eighteen treatment combinations of 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 ) as compared to un-inoculated treatments. Meanwhile, plot with the application of N and S @ 20 kg ha -1 + bio-priming @ 25 g kg -1 seeds on loamy sand soil resulted the increased the seed yield ~ 32, 21 and 7%, respectively and nutrients availability besides organic carbon (5, 2 and 2.3%), available N (5, 4.5 and 4.6%), P 2 O 5 (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.

Impact of Different Rhizobial Strains on Physiological Responses and Seed Yield of Mungbean [Vigna radiata (L.) Wilczek] under Field Conditions

“…The present study revealed that the rhizobial strain MR 63 produced the maximum yield under both the drought and irrigated environment (Chart 2). Similar response of rhizobial inoculation induced yield improvement was reported by Choudhary et al (2019) and Tena et al (2016).…”

Conservation Tillage and Weed Management Influencing Weed Dynamics, Crop Performance, Soil Properties, and Profitability in a Rice–Wheat–Greengram System in the Eastern Indo-Gangetic Plain

“…The higher yield in summer green gram following CT rice and wheat can be attributed to a combination of interconnected factors encompassing residue decomposition and nutrient availability, effective weed suppression, enhanced soil aeration and root penetration, better pest and disease management, and soil moisture conservation [79,80]. CT incorporates crop residues, promoting their decomposition and releasing nutrients that are readily available for the subsequent crop, enhancing the growth, yield, and yield-attributing characteristics of summer green gram [81]. Additionally, CT aids in effective weed control by burying weed seeds and disrupting their germination, reducing competition and providing the summer green gram crop with a competitive advantage [50,59].…”
