| Popis: | A sand culture experiment was conducted using four wheat varieties viz. Sakha 8 (V1), Sonalika (V2), Sakha 3 (V3) and Soltane (V4). Plants were irrigated with nutrient solutions containing three levels of salinity viz. 0 (S1), 44 (S2), and 88 (S2) meq NaCl/liter, and three levels of nitrate viz. 3 (N1, 6 (N2), and 9 (N3) meq NO3 1/liter. Plants were sampled at early spike emergence for measurement of dry matter and contents of Fe, Mn, and Zn. The results are summarized as follows. 1) The efficiency of spike dry matter production percent was promoted by increasing salinity, though, the opposite was observed for the dry matter yield of shoots and spikes. 2) The higher the nitrate level the higher was the dry matter yield per plant and the efficiency of spike dry matter yield production percent as well. 3) Tolerance of the tested wheat varieties to sodium chloride followed the order; V1 < V2 < V3 < V4 and the critical osmotic pressures of sodium chloride, for 50% reduction in dry matter yield, could be predi... |
