| Abstract: |
An experiment was conducted at Rampur, Chitwan to study the effects of N, P2O5 and K2O on
tuber yield, quality and leaf nutrient status of potato cv. Kufri Sinduri and Desiree. The highest
potato tuber yields (35.7 and 21.1 t ha -1) were obtained with 150:100:100 and 100:100:100 of
N:P2O5:K2O kg ha-1 respectively of Kufri Sinduri and Desiree. The optimum dose of N, P2O5 and
K2O was 100:50:50 kg ha-1 for both cultivars. Regression of N, P2O5 and K2O doses on Kufri
Sinduri and Desiree explained 78 and 31% variation, respectively, in the tuber yield. Leaf N alone
accounted for maximum variation (76% and 43% by linear in Kufri Sinduri and Desiree,
respectively). Leaf N, P and K, respectively 5.04, 0.29 and 3.97% dry matter was critical for potato
production under humid sub-tropical condition of Chitwan. Present findings suggest that Nitrogen,
Phosphorous and Potassium fertilizers management should be based on leaf analysis for balanced
application of mineral nutrients in potato crops.
