Low macronutrient levels in the soil greatly affect the yield of Potato (Solanum tuberosum L.) in Uganda. The study was undertaken to determine the effect of macronutrient combinations on yield of potato. This was done in 6 sites across south western Uganda. The 5 levels of N:P:K combinations were laid in split plot arrangement with Mode of Application (MoA) allocated to main plots and nutrient combinations allocated to the sub plots. The results indicated that basal application significantly increased potato yield. Macronutrient combinations led to increase in potato yield with application of 100:75:200 performing better on ware and in season 2. Application of 75:50:150 was good for seed production and in season one when rains are not sufficient. Season 2 was the best season i... view more»
