A Salinity-Fertility Interaction Study on Corn and Cotton

Salinity–mineral nutrient relations in horticultural crops

“…(Ravikovitch and Porath, 1967), corn, Zea mays L. (Khalil et al, 1967;Ravikovitch and Porath, 1967;Ravikovitch, 1973), grape Vitis vinifera L. (Taylor et al, 1987), tomato, Lycopersicon esculentum L. (Ravikovitch and Porath, 1967;Papadopoulos and Rendig, 1983) and spinach, Spinacia oleracea L. (Langdale et al, 1971) when the degree of salinity was not severe. We have found no references to field studies on horticultural crops, however, that showed an increase in crop yield under saline soils where N was applied above a level considered optimal under non-saline conditions (i.e.…”

Potassium-salinity interactions in irrigated corn

“…Offprint requests to: A. Bar-Tal Potassium uptake by plants can be affected by high salinity and the concentration of Na in the soil solution (Helal and Mengel 1979;Khalil et al 1967). There is abundant evidence that Na and the Na/Ca ratio can affect K uptake and accumulation within plant cells and organs (BenHayyim et al 1985(BenHayyim et al , 1987Cramer et al 1985Cramer et al , 1986Kent and Lauchli 1985;Lahaye and Epstein 1971;Lynch and Lauchli 1985) and salt tolerance appears to be correlated with selectivity for K uptake over Na (Lauchli and Stelter 1982;Wrona and Epstein 1985).…”

Mineral Nutrient Acquisition and Response by Plants Grown in Saline Environments

“…bean (14-16), carrots, cowpea, tomato, corn, clover, beans, millet, and vetch (17), coastal Bermuda grass (18), corn and cotton (19), corn and millet (20), tomato (21), spinach (22), and wheat and rice (23) when the degree of salinity was not severe. In most of these studies, the fact that applied N did not improve the growth under extreme saline conditions suggests that applied N decreased plant salt tolerance (see response in Figure 2c).…”
