Abstract: A field experiment was conducted at Agronomy Farm, College of Agriculture, University of Agricultural Sciences, Raichur, Karnataka with the objective to know the uptake pattern of NPK with respect to methods of establishment and varied dates of sowing in Bt cotton in the TBP irrigation command. Uptake of N, P and K was significantly higher in transplanting method (191, 49.6 and 201 kg/ha, respectively) compared to dibbling method of sowing (181, 46.8 and 190 kg/ha, respectively). Among the varied dates of sowing, significantly higher N, P and K uptake was observed with crop sown on 1st fortnight of June (238, 51.8 and 211 kg/ha, respectively) when compared with crop sown in 1st fortnight of August (123, 43.6 and 171 kg/ha, respectively). As a result of this, significantly higher seed cotton yield was observed with transplanting method in the early days of June month. From these results, we can conclude that early transplanting in the month of June leads Bt cotton to uptake higher amount of NPK that results ultimately to higher seed cotton yield especially in irrigation command area.
