Effect of soil alkalinity on growth, yield and some biochemical parameters at grain filling stage in cowpea and Sesbanm cannabina
Abstract
Physiological basis of tolerance to alkalinity in dhaincha Sesbania cannabina (Retz.) Pers and susceptibility in cowpea Vigna unguiculata (Linn) walp. subsp. cylindrica (Linn) Van Eseltine was studied. Poor yield in susceptible cowpea appeared due to adverse effect of root zone alkalinity on branch stem and leaves while [dhaincha had no effect. This adverse effect was followed by decrease in chlorophyll, proteins, RNA and DNA in these active parts in cowpea than dhaincha.
