Languages of publication
The present investigation deals with the effect of zinc on the morphological and biochemical parameters of Cowpea (Vigna unguiculata L) under laboratory condition. The Cowpea plants are grown in petriplates lined with filter paper treated with various concentrations (control, 10, 25, 50, 75, 100, 150 and 200 ppm) of zinc. The experiments were replicated five times. The various morphological parameters such as germination percentage, shoot length, root length, root nodules, total leaf area, fresh weight and dry weight of the plants were measured. Similarly the biochemical contents such as chlorophyll, carotenoid, protein and Sugar was analyzed. The results indicated that the various morphological and biochemical parameters increased up to 50 ppm and decreased at high levels of zinc.
