Abstract:

Field experiment was carried out on wheat crop at N.E. Borlaug Crop Research Centre, G.B.U.A.&T, Pantnagar during Rabi 2016-17 to evaluate the impact of soil fertility gradient on crop yield, nutrient uptake and soil fertility. The experiment field was divided in three equal strips and three graded levels of fertilizer N, P2O5 and K2O were applied as N0P0K0, N100P100K100 and N200P200K200 in strip I, strip II and strip III, respectively. N:P:K mixture, urea and muriate of potash were used as source of nutrients. Exhaust crop wheat was grown by following recommended agronomic practices and harvested at maturity. Straw and grain samples were collected from each strip and analyzed for nitrogen, phosphorus and potassium content and total nutrient uptake was worked out. Grain and straw yield were also recorded after harvesting the crop. Soil samples were taken before and after the harvest of the crop from the surface layer and analyzed for available N, available P and available K. Wide variation in wheat yield, nutrient uptake and soil fertility was recorded between strips which confirmed the impact of graded levels of fertilizer application on these parameters and establishment of soil fertility gradient.


Keywords: Soil fertility gradient, wheat, STCR, nitrogen, phosphorus, potassium, nutrient uptake, yield.
