Abstract:
A field experiment was conducted at an Agricultural Farm Rama University, Kanpur 209217 (U.P) India during Rabi season of year 2021-22. The soil at the test location was clay loamy, with low amounts of organic carbon and available nitrogen, available phosphorus, and medium in available potassium with a moderate alkaline (8.2 pH). The experiment was laid out in Randomized Block design with three replications. Ten treatments viz. T₁-Phosphorus 30 kg/ha + Mb 0.5 kg/ha, T₂-Phosphorus 30 kg/ha+ Mb 1.0 kg/ha, T₃-Phosphorus 30 kg/ha + Mb 1.5 kg/ha, T₄-Phosphorus 40 kg/ha+ Mb 0.5 kg/ha, T₅-Phosphorus 40 kg/ha + Mb 1.0 kg/ha, T₆-Phosphorus 40 kg/ha + Mb 1.5 kg/ha, T₇-Phosphorus 50 kg/ha + Mb 0.5 kg/ha, T₈-Phosphorus 50 kg/ha+ Mb 1.0 kg/ha, T₉-Phosphorus 50 kg/ha + Mb 1.5 Kg/ha and T₁₀-Only Recommended Dose of Fertilizer (RDF) were allocated in randomly. Higher growth attributing characters (plant height and dry matter accumulation) and yield attributing characters at harvest number of pods plant^-1, Length of pods (cm^-1), number of seed pods^-1 and test weight (G) were produced in black gram with T₁₀-Only Recommended Dose of Fertilizer (RDF) treatment. Similarly, higher seed, straw, biological yield, highest harvest index along with net monetary income was recorded under Recommended Dose of Fertilizer in black gram crop; However, Highest benefit cost ratio (21.9) produced under T₉ - Phosphorus 50 kg/ha + Mb 1.5 Kg/ha treatment.
