“…Also, it is well known that potassium and calcium in substrates can have a very definite influence on transpiration and water uptake by plants (Biebl, 1958). A better knowledge of their interactive effects on salt-stressed plants may contribute to better agrotechniques for irrigated agriculture.…”

Combined effects of leaching fraction, salinity, and potassium content of waters on growth and water-use efficiency of wheat and barley

Wheat and barley seedlings growing in pots in a greenhouse, with a non-saline sandy loam soil were irrigated, by saline waters, $1, $2, and $3, having EC i = 3, 9, and 15mScm -1, respectively. Each solution has three potassium concentrations, K~ = 6, K 2 = 11, and K 3 = 16meq L -l, and all incorporated N (90mgL -l) and micro-nutrients. Irrigation was provided to realize 0.2 and 0.5 leaching fractions (L).At maturity, dry matter of plant tops (Y), grain yield (G), and evapotranspiration (ET) of both crops responded significantly to the S, L, and K treatments. There were different interactions, however, between the crops indicating some effect of plant species. In both, a decrease in Y with increasing salinity was associated with a corresponding decrease in ET. In the most saline S 3 treatments, where the available water to plants was the lowest, an ample K supply produced substantial improvements in salinity tolerance of both crops. Under these conditions, changes in Y and ET were independent of each other. Increasing K supply, reduced the rate by which Y decreased with respect to S. Barley accumulated dry matter more efficiently (in terms of ET y -l , g per g) particularly under L = 0.2. This efficiency for both crops did not respond to the water salinity but rather to the potassium concentration of the waters.The whole experiment was also carried out under two levels of phosphorus application (35 and 70 mg P kg i soil). Neither growth nor water-use efficiency were significantly affected by the higher rate of phosphorus application.

“…A plant with full nutrient supply was found to have a water uptake amounting to 75 "/o of that measured from potassium deficient plants. Biebl (1958) concluded that both a decrease and an increase in the transpiration rate was reported for different K'^-levels, and he believed the reason for this to be the age of the plants examined, younger plants showing a decrease, older an increase. Allerup (1965) studied the effect of single salt solutions on the transpiration and found the transpiration rate to increase after addition of potassium salts.…”

The investigation concerns the influence of potassium on the transpiration rate of Triticum aestivum and Pisum sativum grown in nutrient solutions. Plants with high amounts of potassium were found to have the lowest transpiration rates. Shoot/root ratio, stomatal frequency, and stomatal aperture were correlated with the potassium concentration in the leaves. In Triticum no correlations with leaf concentration of Na were evident.Short term experiments were carried out in order to investigate the effects on the transpiration rate of a sudden increase in potassium concentration in the nutrient solution. An addition of potassium chloride to potassium deficient wheat plants resulted in a decrease in the transpiration rate of up to 50 "/o within two hours. Comparative tests with sodium chloride resulted in a decrease in transpiration rate of the same magnitude, indicating that the short-time reaction is not specific to potassium.The experiments show that the transpiration rate can be regulated by varied potassium and sodium concentrations. The observed effect is supposed to be due to changes in the stomatal aperture.
