“…1b and c) as indicated by many investigators (Ashraf et al, 2011;Ali et al, 2012;Kausar et al, 2012;Kausar and Gull, 2014b). The reason for this could be due to the lowering of stomatal conductance, fixation of carbon dioxide, and disturbance in biochemical reactions/activities (Ashraf et al, 2011;Ashraf et al, 2013Ashraf et al, , 2015. The application of K 2 SO 4 alleviated the adverse effect of salinity stress on the plant height and was effective in enhancing the growth of wheat in stress medium (Fig.…”

Abstract. Salinity is a major abiotic stress which adversely affects productivity of all crops in the world specifically in cereals. Different strategies are being utilized to enhance the overall plant growth and productivity all over the world. The crop nutrients management is one the best options to increase the plant productivity in saline soils. The present study investigated the influence of potassium sulphate (K 2 SO 4 ) in improving plant productivity and nutrient uptake in wheat grown under saline environment. Two wheat genotypes were subjected to different concentrations i.e., 0, 50, 100, 150 and 200 mM of K 2 SO 4 grown at 0, 150 mM sodium chloride stress. The use of K 2 SO 4 increased the fresh and dry plant biomass of both wheat genotypes with a maximum increase at 200 mM K 2 SO 4 under saline and nonsaline conditions. It was observed that the uptake and accumulation of nutrients like calcium, magnesium, potassium and phosphorus increases in plants subjected with K fertilizer application under saline environments in both wheat genotypes.

“…However, both NAYAB-11 and MILLAT-11 varieties responded positively to potash fertilizer under salinity conditions, and it also increased significantly with increasing level of potassium ( Table 2). The reduction in root lengths by the application of salt stress was also reported by Kausar et al (2012) and Ashraf et al (2013). A number of other researcher also depicted similar results (Irshad et al, 2002;Ali et al, 2012;Kausar & Gull, 2014).…”

Wheat is cultivated throughout the world to meet the needs of food and feed and industrial raw material in several countries. The salinity has been confirmed as main constrain of crop production and major threat to the agriculture. There is a need to increase the wheat production in marginalized soils. Different strategies have been adopted to increase the crop productivity in the world. During the current study effect of potassium sulphate was investigated for crop production in the salt stressed areas. Different application rate of K 2 SO 4 (i. e., 50, 100, 150, 200 mM) under 150mM NaCl stress were used. It has been observed that the application of K 2 SO 4 has increased the biomass production irrespective of the rate of application. The application of 200 mM K 2 SO 4 proved to be the best to increase the maximum biomass in saline environment. It was also observed that the use of fertilizer has also increased the uptake of essential nutrients like potassium, calcium, magnesium and phosphorus in saline soils.

“…Adequate K nutrition has important effects on the composition of harvested products and the quality of diet, especially under some stress (Ashraf et al 2013). However, K (+) content in soils is usually limited, and so the crop yields are restricted.…”

In order to investigate the effect of potassium (K) nutrition on secondary metabolism, Catharanthus roseus was treated by different concentrations and forms of K nutrition (KNO 3 and K 2 SO 4 ). The results showed that the concentration of applied K obviously affected plant growth and biomass accumulation, while K form had little influence. The concentration of alkaloids, including vinblastine in the leaves and catharanthine in the leaves or roots, had a significant increase, especially upon 80 and 100 mM K nutrition. The measurement of internal ion content using energy dispersive spectroscopy displayed that the increase of K element in leaves was tightly correlated with elevated alkaloid concentration. The transcript levels of G10h, Str, and Dat genes, encoding key enzymes in the alkaloid biosynthesis pathway, were significantly activated by applying P and tightly related to alkaloid accumulation. In conclusion, our results provided the physiological and molecular evidence that potassium could effectively regulate alkaloid metabolism in C. roseus.
