 ABSTRACT

Present field experiment was conducted at the Instructional Farm, College of Agriculture, S.K. Rajasthan Agricultural University, Bikaner, during Rabi season in two consecutive years (2016-17 and 2017-18) to find out the effect of nitrogen, potassium and sulphur fertilization on nutrient uptake and yield of onion in arid western Rajasthan. The treatments laid out in a split plot design replicated thrice.The results of the study have clearly showed that methods and application levels of nitrogen, potassium and sulphur significantly increased N, P, K and S uptake and bulb yield.  Similarly, result revolted that the nitrogen fertilization of @ 80 kg  N ha-1 (soil application) + 20 kg N ha-1 (4 foliar sprays), recorded highest bulb yield (227.62 q ha-1), which were closely followed by N2 (210.45 q ha-1) which was significantly higher over control.

Keywords: Nitrogen, Potassium, Sulphur, Bulb yield, Nutrient uptake, Onion
