a field study was conducted to evaluate the agronomic response of eight isolines of cv. clark on a clay loam soil (at karaj-iran, 35048´) to four plant population densities of 11.3, 18.5, 68.5, and 103.4 plants per square metre. significant yield increase was obtained as a result of higher plant density. differences among the cv. clark isolines were significant (p

Due to their sessile nature, plants have confront the stresses and develop potent adaptive tactics survive thrive or tolerate adverse effects. Abiotic stresses, pose a severe threat multiple morphologies, biochemistry, physiology procedures agriculture ecosystem. On other hand, reductions in crop yields brought about by abiotic stress are expected increase as climate change restricts worldwide ...
