A field experiment was carried out to assess the effect of NPK on vegetative growth and yield of potato cultivars; Kufri Sindhuri and Desiree at different nutrient levels (0:0:0, 50:50:50, 100:50:50, 100:75:50, 100:75:100, 100:100:100 and 150:100:100 N, P 2 0 5 and k 2 0 kg ha -1 ) in sandy loam soils at Rampur, Chitwan, Nepal during 1999/2000. The experiment was laid out in a split plot design with 4 replications. Plant height, number of stems, fresh weight of stem and leaves were recorded at 15 days interval during crop growth period and tuber yield at maturity stage. Kufri Sindhuri was taller than Desiree at all the stages of plant growth. Increasing levels of NPK increased the plant height by 15-42 percent. The levels of NPK imparted to a significant effect on fresh weight of leaves and stems at each successive stages of crop growth. Kufri Sindhuri responded nitrogen up to 150 kg ha -1 while Desiree yielded higher at 100:100:100 kg NPK ha -1 . The yield increase of potato tuber was associated with increase in the plant height, fresh weight of leaves and stems as a result of applied NPK.

“…In addition, under-or oversupply of N may affect total number of tubers (O'Brien, Allen, and Firman 1998). Applications of K fertilizer only affected the number of tubers on very low index soils (O'Brien, Allen, and Firman 1998), and Sharma and Aroma (1987) found that an increase in N and K significantly decreased the number of tubers m -2 in small (<25 g) grades and increased the number in medium (25-75 g) and large (>75 g) grades at 45, 60, 75, and 90 days after planting.…”

A potato field experiment was conducted for 2 consecutive years to determine the effects of nitrogen (N) and potassium (K) fertilization rates on the yield and quality of potato cv. Spunta cultivated on soil low in N and K. A 3 × 4 complete factorial experiment was used with three rates of nitrogen (330, 495, and 660 kg N ha -1 ) and four rates of potassium (112, 225, 450, and 675 kg K 2 O ha -1 ). An additional treatment without fertilization was used as the control. On soils low in N and K, potatoes showed low yield response to K fertilizer. The greatest tuber yields for both years were achieved at 495 kg N ha -1 and 112 kg K 2 O ha -1 (29.81 t ha -1 ) and 225 kg ha -1 (27.13 t ha -1 ), respectively. Differences in mean fresh weight due to treatment application were not significant. Application of 495 kg N ha -1 significantly reduced harvest index (the ratio of tuber dry weight to the total dry weight at harvest) compared to 330 kg N ha -1 , but at 660 kg N ha -1 harvest index achieved the greatest significant value. Potassium fertilization had no significant influence on harvest index. Nitrogen rates positively influenced the number of tubers. The addition of 450 kg K 2 O ha -1 significantly enhanced the number of tubers compared to the lower K rates, and the number was significantly decreased by the application of 675 kg K 2 O ha -1 . Tuber dry-matter concentration was significantly promoted by N fertilization in both cultivation years, but it was negatively affected by K fertilization in the first year of cultivation. There was no change in tuber N with N application, but N application strongly increased nitrate (NO 3 ) concentration, which fluctuated between 360 and 1382 mg kg -1 wet mass. Tuber NO 3 was negatively correlated with tuber yield, indicating that high levels of NO 3 in tubers can adversely affect yield. Tuber response to K fertilization was not in accordance with the rate of applied nutrient.

“…It is predicted from the results that variety Senna-Red produce maximum tuber weight as compared to other genotypes. [28,3] reported that it might be due to increase in weight of tuber nitrogen being the constituent of chlorophyll, promoted cell division and cell elongation, functional life of plant and production of carbohydrate.…”

“…Its growth, yield and quality largely depend on soil and climatic condition as well as on different production practices. Available reports indicate that the yield of potato increased substantially through adequate application and judicious management of fertilizers [3]. It is mainly produced on coarse textured calcareous soils in arid land and under center pivot irrigation systems.…”

The present study was carried out to evaluate response of potato genotypes to different levels of nitrogen at fruit and vegetable nursery, Department of Horticulture, The University of Azad Jammu and Kashmir-Pakistan during the cropping season 2014. The experiment was laid out in Randomized Complete Block (RCB) Design with split plot arrangement, consisting of nitrogen levels and potato genotypes. There were five levels of nitrogen i.e. (0, 80, 100, 120 & 140 kg N ha -1 ) and three potato genotypes viz., Ronaldo, Senna red and HZD 00-112. The data was collected for different growth and yield parameters at each and every level of nitrogen. The highest significant values for most of the traits studied were recorded at 120 kg ha (59.45), plant height (52.56 cm), number of tuber plant -1 (8.03), tuber diameter (4.56 cm), average weight of tuber plant -1 (375.07g), and yield of tuber plot -1 (22.80-ton ha -1 ). Potato variety Ronaldo has given the highest yield (27.85 tones ha -1 ). Based on the results of the present study, it is recommended that application of nitrogen at 120 kg ha -1 can enhance over all productivity of potato under prevailing environmental conditions of Rawalakot, KashmirPakistan.
