Abstract:
A field study entitled ‘Effect of rhizobium, foliar spray of nutrients and plant growth regulators on growth and yield of summer green gram [Vigna radiata (L.)]’ was conducted during summer 2021 at LPU, Phagwara. The treatments comprised of four main plots of foliar sprays (S₀, S_19:19:19, S_GA and S_NAA) and three subplots of fertilizers (no fertilizer, rhizobium, recommended dose fertilizer + rhizobium designated as F₀, F_R and F_RDF+R, respectively) with three replications in split plot design. Irrespective of fertilizers, there was significant increase in grain yield with foliar spray of S_GA as compared to S₀. There was further significant increase in grain yield with foliar spray of S_19:19:19 and S_NAA. The higher grain yield under the foliar spray of S_19:19:19 was accompanied by significant increase in growth and yield attributes. Irrespective of foliar sprays, the fertilizers F_R increased the grain yield significantly as compared to F₀ but F_RDF+R resulted in further significant increase as compared to F_R. The higher grain yield of green gram under the application of F_RDF+R was accompanied by significant increase in growth and yield attributes. The interaction between foliar sprays and fertilizers was significant. The highest grain yield (1242 kg ha^-1) was under the application of F_RDF+R with S_19:19:19 which was 19% higher than S_19:19:19 F₀ and 22% higher than S₀F_RDF+R. F_RDF+R when applied in combination with S_19:19:19 resulted in maximum gross returns, net returns and B: C ratio.
