Abstract
Background: Wheat productivity in semi-arid regions is relatively lower than the world’s average due to environmental stress, largely drought and nutrient depletion. Potassium (K) enhances nutrient and water uptake, photoassimilate production and enzyme activation. The objective was to investigate the effect of different K application rates on nutrient content and uptake of wheat crop grown under rain-fed conditions. The impact of the K application on soil salinity was also examined. Methods: Two local wheat (Triticum durum L.) varieties were investigated at two rain-fed sites. Five different rates of K were applied (0, 20, 40, 60 and 80 kg K2O ha-1). Result: Potassium application rate at 40 to 60 kg K2O ha-1 enhanced the nutrient uptake of the wheat crop; meanwhile, the soil salinity tended to increase.
