Wheat requires potassium for its optimal growth and development. Adequate potassium supply can increase the quality of the plants by improving crop against biotic and abiotic stresses. Current study was carried out to observe overall performance of wheat genotypes under various potassium levels during 2014-15. The experiment was set under completely randomized design (CRD) with factorial arrangements in three replications. Present study displayed that growth and yield mechanisms of different wheat genotypes positively responded under adequate and deficient K levels. The results showed that mean values under adequate K level were found highest (P<0.05) i.e. 100.0 cm plant height, 23.0 tillers plant-1, 21.0 spikes plant-1, 17.0 cm spike length, 60.0 grains spike-1, 37.0 g seed index value, 24000.0 kg ha-1 biological yield and 7700.0 kg ha-1 grain yield in SD-4086/3 genotype respectively, as compared to the deficient K level i.e. 85.0 cm plant height, 18.0 tillers plant-1, 17.0 spikes plant-1, 15.0 cm spike length, 46.0 grains spike-1, 32.0 g seed index value, 20000.0 kg ha-1 biological yield and 7000.0 kg ha-1 grain yield in SD-4086/3 genotype respectively. Furthermore, the genotypic response at both adequate and deficient K levels in all observations were recorded lower in genotype NIA-MB-II. Whereas, overall performance of all genotypes under adequate and deficient K levels was satisfactory but genotype SD-4085/3 responded better than other genotypes in each character. It could be concluded that genotype SD-4085/3 was seems to be performed excellent under adequate and deficient potassium environment.
