Effect of different levels of NPK fertilizers on potato tuber yield


, : Effect of different levels of NPK fertilizers on potato tuber yield. Sarhad Journal of Agriculture 9(6): 543-550

Due to rising economic importance of potato as food and cash crop in Pakistan, particularly in Northern Areas and the need to improve the productivity with judicious use of fertilizers, three trials one each at Naltar, Khyber (1990) and Babusar (1992) were conducted with the commercial cultivar Diamant. The response of NPK fertilizers in ten combinations was studied. The results revealed that 250 kg P-2O-5 and 100 kg N, 125 kg K-2O/ha produced the highest yield, but it was at par with treatments 200 kg N, 125 kg P-2O-5 and 100 kg K-2 O(T-10), 200 kg N, 125 kg P-2O-5 and 75 kg K-2 O(T-9) and 200 kg N, 100 kg P-2O-5 and 75 kg K-2O/ha(T-8). All these 4 treatments were significantly different from rest of the treatments. It is suggested that 200 kg N, 100 kg P-2 O-5 and 75 kg K-2 O/ha is the most economical combination and further increase in fertilizer dose could not contribute towards significant increase in yield. The economics of each fertilizer practices was worked-out on the basis of current market prices and it was found that the use of fertilizers in all combinations was profitable, the cost benefit ratio ranged between 1:10.82 to 1:24.08. It is realized that each unit of fertilizer increase in input resulted an average increase of 18.27 units in output.
