Abstract

Aims: To investigate the effect of phosphorus and bioinoculants on nutrient uptake and available soil nutrients by black gram. Study Design: Randomized Block Design. Place and Duration of Study: Agronomy farm of Lovely Professional University, Phagwara, Punjab during summer (2023). Methodology: The experiment comprised of nine treatment combinations (T1- control, T2- 20 kg P2O5 ha-1, T3- 40 kg P2O5 ha-1, T4-20 kg P2O5 ha-1+PSB, T5-40 kg P2O5 ha-1+PSB, T6-20 kg P2O5 ha-1+VAM, T7-40 kg P2O5 ha-1+VAM, T8-20 kg P2O5 ha-1+PSB+VAM, T9-40 kg P2O5 ha-1+PSB+VAM), each replicated thrice.  Results: The results demonstrated that the application of 40 kg P2O5ha-1+PSB+VAM (T9) recorded the highest soil available nitrogen (188.63 kg ha-1), and phosphorus (32.68 kg ha-1) compared to all other treatments. The maximum nitrogen content in grain and stover (3.88 % and 1.64 %) and phosphorus content in grain and stover (0.408 % and 0.228 %) were also overserved in the T9 (40 kg P2O5 ha-1+PSB+VAM) treated plots. Similarly, T9 treated plots recorded the highest uptake of nutrients in grain and stover i.e., nitrogen (41.86 and 38.17 kg ha-1), phosphorus (4.4 and 5.3 kg ha-1), and potassium (9.11 and 42.58 kg ha-1). Conclusion: The cultivation of black gram by applying 40 kg P2O5 ha-1+PSB+VAM can be beneficial for the restoration of soil available nutrients, nutrient content and uptake of black gram.
