Abstract
The experiment was conducted to study the impact of basal and split potassium nutrition on two wheat varieties and their relative response at the experimental field of Barley and Wheat Research Institute Tandojam, Pakistan during 2018-19. Two wheat varieties, viz. TD-1 and Kiran-95 were grown in Randomized Complete Block Design with three replications. The treatments were as follows: T1 = No K application, T2 = K application at 50 kg K2O ha-1 at the time of sowing, T3 = K applications in two splits, i.e. 20 kg K2O ha-1 at sowing and 30 kg K2O ha-1 at tillering stage. The treatment wise observation were recorded on number of tillers plant-1, number of grains plant-1, (cm), seed index (1000 grains weight g),grain yield (kg ha-1), straw yield (kg ha-1), and K content (%) in grains and straw. The K application in two splits showed great response as compared to basal application alone. In case of varieties, TD-1 performed well relatively in all parameters. For higher crop production therefore, K should be applied in two different splits.
