Abstract: E stablishment of a suitable tillage system for improving wheat yield under variable level of irrigation and potassium is important for developing sustainable agriculture.Thus, present investigation was carried out at Experimental Farm, Department of soil science, CSKHPKV, Palampur during Rabi 2016-17 to evaluate the effect of different combination of tillage, irrigation and potassium on nutrient uptake by plants and soil properties.The field experiment was laid out in split-plot design with two tillage methods i.e., C 1 : Conventional tillage and C 2 : Conservation tillage and two irrigation Levels i.e., I 1 : No irrigation and I 2 : Two irrigations in main plot and three Potassium level i.e., K1:100%, K 2 :125%, and K 3 :150% of recommended dose of potassium in sub-plots with three replications.Maximum uptake of N, P and K was observed under conservation tillage system and among the irrigation level, application of two irrigation remained best over no irrigation.Among the potassium level, wheat crop fertilized with 150% of recommended dose of potassium recorded maximum uptake of N, P and K. Soil properties viz., soil pH, soil organic carbon and available N, P and K improved under conservation tillage and two irrigation applications at both depths while soil pH and soil organic carbon were not affected by different level of potassium.However, available potassium was more improved by 150% of recommended dose of potassium at both depths.Bulk density of soil at both the depth was more improved under conventional tillage system, no irrigation supply and 100% recommended dose of potassium.
