PERFORMANCE OF POTATO (Solanum tuberosum L.) VARIETIES ON DIFFERENT FERTILIZER TREATMENTS

Abstract

Potato crop has strict requirement for a balanced fertilization management, without which growth and development of the crop are poor and both yield and quality of tubers are diminished. Therefore, the study was done to make evaluated the effect of fertilizer management practices on the growth, yield and tuber quality characteristics in three potato varieties. Treatments included four doses of fertilizers 0 , F 1 , F

2 Regarding varieties, the minimum days treatment where the treatment doses of N, P, K, S, Mg, Zn and B were 100, 30, 120, 10, 10, 4 and 0.8 kg ha 2 -1 , respectively. According to the results it can be concluded that Cardinal produce have the capability to produce higher tuber yield with quality grade of potato. On the other hand, fertilizer management practices had significant effect on growth, yield and grade of potato. Among the fertilizer treatments, F can be suitable dose for higher yield with better quality of potato in case of each of cardinal, granola and diamant variety. It is concluded that high yields and enhanced quality

and F 3 tubers can only be sustained through the application of optimal nutrient doses in balanced proportion of F 2 treatment in potato cultivar Granola.
