Abstract

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2018-19 and 2019-2020 to find out suitable phosphorus fertilizer source and application method for higher brinjal production and to increase phosphorus use efficiency. There were six treatments comprising T1 = P from TSP (100% basal dose), T2 = P from DAP (100% basal dose), T3 = P from DAP (50 % basal + 50% top dress), T4= P from DAP (25 % basal + 75 % top dress), T5 = P from DAP (100 % top dress) and T6 = P-control. NKSZnB were used as a blanket dose in all treatment. Two years results revealed that, DAP fertilizer gave superior performance over TSP fertilizer. The highest average brinjal fruit yield (33.13 t ha-1) was found in T3 treatment [DAP application (50 % basal + 50% top dress)] compared to TSP treatment (30.05 t ha-1) and the lowest (17.97 t ha-1) came from T6 (control treatment). The highest phosphorus use efficiency (433.14 Kg yield/Kg P) and highest phosphorus recovery (28.75%) was also obtained from DAP treatment with highest BCR (3.6) compared to TSP treatment. It was conclude that, splitting application of DAP fertilizer led to an increased of P availability at proper time of demand which effects on growth and yield of brinjal.
