Potassium Fertilizer Influences Growth Traits and Yield of Wheat (Triticum aestivum L.) under Saline Regime

Abstract

Soil salinity is one of major deleterious abiotic stress limiting the yield of wheat crop. Plant growth produce is severely affected by various biotic and environmental and metabolic processes. Application of Potash fertilizer can reduce the harmful effects of saline stress and increase crop yield. This research was carried out to evaluate detrimental effects of salinity stress on wheat produce and to suggest appropriate dose of potash fertilizer to achieve optimum production under saline conditions. There were four K doses as (ck, 50, 3/4th and 100 kilogram K2O/ ha). The results depicted that potash fertilizer application increased wheat crop growth traits and produce substantially under saline regime, significantly. With potassium supplement, height of plant enhanced about 19.23 %, tillers per plant (36.24 %), length of spike (27.33 %) cm, wheat grains (23.5 %), and grain production increased (24.11 %) kg/ha. It was concluded that soil applied potassium fertilizer as K rate at 100 kg K2O yielded in maximum crop growth development and wheat produce at rate of 50 and 75 kg K2O ha-1. Therefore, potash fertilizer at rate of 100 kg K2O ha-1 may be adopted for optimum yield in wheat under saline environment.
