Abstract:

The experiment was laid out during summer season of 2015 at Forest Nursery, School of Forestry and Environment, SHIATS, Allahabad, UP, India to study the effect of different levels of NPK in combination with Rhizobium and PSB culture on growth of green gram (Vigna radiata L. Wilczek) under subabul (Leucaena leucocephala) based agroforestry system. The subabul was planted at a spacing of 8×1 meter and green gram was sown under subabul based agroforestry system. The experiment was conducted in randomized block design having three levels of N + P + K and seed inoculated by strain Rhizobium (MOR-1) and Phosphate Solubilising Bacteria (Bacillus subtilis) of Green gram (Vigna radiata L. Wilczek.) with three replications. The inoculants were obtained from the Department of the Agroforestry, School of Forestry and Environment, SHIIATS, Allahabad. The treatments were randomized as per statistical procedure. Experiment consisted of total 9 treatment combinations: T1-Control, T2- 20-20-10 kg NPK/ha, T3- 30-30-15 kg NPK/ha, T4- 40-40-20 kg NPK/ha, T5- 50-50-25 kg NPK/ha, T6- 20-20-10 kg NPK/ha + Rhizobium and PSB culture, T7- 30-30-15 kg NPK/ha+ Rhizobium and PSB culture, T8- 40-40-20 kg NPK/ha+ Rhizobium and PSB culture and T9- 50-50-25 kg NPK/ha+ Rhizobium and PSB Culture. The result revealed that during summer season green gram cultivar of cv. HUM-16 performed best fertilized with (T7- 30-30-15 kg NPK/ha) with dual seed inoculation of rhizobium and PSB culture. This treatment combination found more productive and economical, which closely followed by the treatment combination of (T4- 40-40-20 kg NPK/ha).
