ABSTRACT
A field experiment was conducted at Research Farm of Maharishi Markandeshwar (Deemed to be University), Mullana, Ambala during summer season of 2023-24. The experiment was laid out in factorial randomized complete block design with three replications involving two factors i.e. nutrient combinations (Factor A) and green gram varieties (Factor B). Factor A comprised eight N:P:K fertilizer levels (kg/ha): F1–15:40:00, F2–15:40:20, F3–15:50:00, F4–15:50:20, F5–20:40:00, F6–20:40:20, F17–20:50:00 and F8–20:50:20, while the Factor B included two different green gram varieties V1–MH 1142 and V2–MH 421. The required amounts of nitrogen, phosphorus and potassium were applied to each plot separately based on the treatment schedule as a basal application before sowing. The results revealed that the application of 20:50:20 kg/ha N:P:K (F8) significantly resulted in higher plant height, number of leaves/plant, dry matter accumulation and seed yield which were also found statistically at par with application of 15:50:20 kg/ha N:P:K (F4) and 20:40:20 kg/ha N:P:K (F6) indicating higher carbon accumulation in plant foliage in these treatments. Further, the data revealed a positive and strong correlation between different growth parameters and seed yield of green gram. It can be concluded that application of 20:50:20 kg/ha N:P:K
was found to be the most effective treatment for enhancing productivity of green gram as well as carbon sequestration. Hence, this approach offers a viable pathway to sustain pulse productivity while simultaneously contributing to agroecosystem carbon-mitigation strategies.
