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 (281369) 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.
