Influence of various NPK combinations on yield and storability of the potato variety 'Atlantic' was studied using quadratic regression of three factors and five levels of saturated D-optimal design. The regression model was created between the fertilizer application and yield and storability as fol owing:Y yield=5120.36+2167.19x1+478.94 x2+1213.65 x3+716.24 x1 x2+1450.95 x1 x3-237.30 x2 x3-2840.03 x12+1013.08 x22-1363.52 x32(-1≤xj≤1),Ystorabil ty=102.95+35.27x1+12.11x2+12.69x3+17.34x1x2+17.93x1 x3-5.24x2 x3-65.18x12-1.01x22-6.72x32 (-1≤ xj ≤1). As for the yield benefit, the fertilizer application of high yield was N=204.07 kg/ha,P2O5=90.58 kg/ha,and K2O=211.28 kg/ha, whose ratio was N:P2O5:K2O=1??0.44??1.04;the optimum fertilizer rate was N=110.40 kg/ha,P2O5=90.58 kg/ha,and K2O=105.64 kg/ha;the optimum output would vary between 7 040.45-8 893.21 kg/ha. As for the storability benefit, the fertilizer application of high storability was N=198.00 kg/ha, P2O5=157.93 kg/ha, and K2O=151.95 kg/ha, whose ratio was N:P2O5:K2O=1:0.80:0.77;the optimum fertilizer rate was N=127.57 kg/ha, and P2O5=78.97 kg/ha, K2O=75.97 kg/ha. Improvement of potato storability could be realized by decreasing the ratio of nitrogen and phosphorus.
