Abstract:
The experiment was conducted during the summer 2021 at Educational Farm, Polytechnic in Horticulture, Junagadh Agricultural University, Junagadh. There were eight treatment combinations replicated thrice in a randomized block design. Among the eight treatments combination tested, organic carbon was significantly higher (0.78%) in T₈ (100% N from FYM), available nitrogen was higher (303.4 kg/ha) in T₃ (50% N from vermicompost + 50%N from inorganic fertilisers), and P₂O₅ (44.10 kg/ha) and K₂O (376.4 kg/ha) in T₇ (100%t N from vermicompost). The highest N (2.21%, 2.07%), P (0.39%, 0.27%) and K (1.57%, 2.75%) content in fruits and stover respectively; maximum N (15.81 kg/ha, 23.14 kg/ha), P (2.80 kg/ha, 3.05 kg/ha) and K (11.22 kg/ha, 30.69 kg/ha) uptake in fruits and stover respectively in the treatment T₃ (50% N from vermicompost + 50%N from inorganic fertilisers). The combined use of organics along with the inorganic fertilizers increased nutrient use efficiency, apparent nutrient recovery and the available nutrient status of the soil.
