“…These findings were significant in the first year of cultivation only. Nitrogen fertilization generally increases the total number of tubers (Sommerfeldt and Knutson 1965;Hanley, Jarvis, and Ridgman 1965). White and Sanderson (1983) reported no substantial influence on the tuber number.…”

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.

“…Moreover, research findings also showed that increment of available soil phosphorous up to certain level through application of phosphorous containing fertilizers may increase tuber weights of potatoes. Further increase of available soil phosphorous however may not increase the tuber weights rather it hasten the maturity of potato plants that may result medium, and small-sized tubers (Hanley, Jarvis, & Ridgman, 1965;Sharma & Arora, 1987;Sommerfeldt & Knutson, 1965).…”

Application of organic and inorganic fertilizers is essential for sustainable production of crops including potato. This study was therefore initiated to identify the optimum rate of farmyard manure (FYM) and blended compound NPS fertilizer for profitable production of potato in Koga Irrigation Scheme, Northwestern highlands of Ethiopia. Four rates of FYM (0, 4.5, 9, and 13.5 t ha −1) and NPS fertilizer (0, 81.7, 163.4, and 245.1 kg ha −1) were laid down in Randomized Complete Block Design with three replications. The results revealed that FYM and blended NPS fertilizer as well as their combination influenced most of the tested growth and yield parameters of potato including plant height, main stem number, and tuber weight. Application of 245.1 kg ha −1 NPS combined with 13.5 t ha −1 FYM recorded the highest marketable and total tuber yields of 43.52 and 47.04 t ha −1 , respectively. Although, the highest marginal rate of return was obtained from plants supplied with the combination of 4.5 t ha −1 FYM and 163.4 kg ha −1 NPS fertilizer, combined application of 245.1 kg ha −1 NPS and 13.5 t ha −1 FYM is recommended for economical production of potato in the study area as it recorded the highest net benefit with acceptable marginal rate of return.

SummarySix field experiments, three each during 1982–3 and 1983–4, were conducted on a sandy loam soil to study the effect of varying levels of nitrogen, phosphorus and potassium, in the absence and presence of farmyard manure (FYM) (30 t/ha), on the number of tubers and yield of potato in three grades. Increase in nitrogen, phosphorus and potassium application, in the absence or presence of FYM, did not significantly affect the total number of tubers/m2 but did affect the number of tubers in different grades. An increase in nitrogen and potassium significantly decreased the number of tubers/m2 in small (< 25 g) and increased in medium (25–75 g) and large (> 75 g) grades at 45, 60, 75 and 90 days after planting. Increase in the application of phosphorus increased the number of tubers/m2 in the small grade and decreased it in the large grade but did not affect the number in the medium grade. Increase in nitrogen and potassium application decreased the tuber yield in the small grade and increased it in the medium and large grades. Applied phosphorus increased the yield in the small and medium grades and decreased it in the large grade. The increase in the yield of tubers with increase in nitrogen and potassium application was found to be caused by an increase in the number of tubers in the medium and large grades at the expense of the small grade; however, with applied phosphorus the increase in yield was due to increase in the weight of individual tubers within the small and medium grades. FYM application decreased the number of tubers in the small grade and increased it in the medium and large grades. The response of potato to nitrogen increased and to phosphorus and potassium decreased with the application of FYM.
