Abstract :
The experiment was conducted at Hazara Agricultural Research Station, Abbottabad, Pakistan during the year 2004-05. The most popular variety of potato “Desiree” was analyzed to find out the effect of different doses of NPK on its proximate composition. The results showed that NPK fertilizers had significant effect on nutrient composition of potato. Moisture content was in the range of 68.8 percent in T6 (140:140:210 NPK) to 81.4 percent in T2 (60:60:90 NPK). Crude protein contents were very low in potato, which were from 0.9percent in T1 (control) to 1.4 percent in T6 (140:140:210 NPK). Percent fats of potato dropped off by increasing the doses of NPK. Fat was lowest as 0.4 percent in T7 (160:160:240) and highest as 1.2 percent in T1 (control). The crude fiber in potato is enhanced by rising amount of NPK. The crude fiber and ash content were ranging from 1.99 (T5) to 3.59 (T7) percent and 3.68 (T7) to 5.18 (T5) percent respectively. From above results it is commended that right amount of NPK fertilizers should be applied to gain high yield and nutritious product.
