ABSTRACT
A field experiment was conducted at MM(DU) Mullana, during kharif season of 2024, to investigate the effect of phosphorus (P) and foliar zinc (Zn) application on carbon sequestration potential, growth and yield of green gram. Experiment was laid in split-plot design with three replications. Phosphorus was applied in main plots with four levels i.e. control, 75, 100 and 125% RDP, while foliar zinc was applied in sub-plots with three levels i.e. control, 1.0 and 1.5%. Growth parameters such as plant height, branches/plant, dry matter accumulation and seed yield were significantly improved with the application of 125% RDP to the tune of 68.3 cm, 6.0 branches per plant, 3.09, 16.46 g/plant, and 1089 kg/ha, respectively. Application of 1.5% zinc in the form of foliar spray also resulted in remarkable enhancement in these growth parameters and yield attributes compared to control. On the basis of interaction effect of both the factors on yield, application of 100% recommended dose of phosphorus along with 1.0% foliar spray of zinc was recommended as the most effective and economical method to enhance carbon sequestration as well as productivity in green gram. This combined nutrient management approach resulted in statistically at par seed yield with higher dosages of phosphorus and zinc and hence it was a viable path to sustain pulse productivity while making a contribution towards agroecosystem carbon reduction plans.
Key words: Phosphorus, zinc, carbon sequestration, green gram, yield
