Abstract:
Studies were made on the effect of phorate granules applied along withs
seeds at the time of sowing on nodulation in cowpea treated with Rhizobium a compared to nodulation in untreated seeds. In Rhizobium treated plants, phorate
caused suppression of nodule development and increase In nodular size,
fresh weight and dry weight. In plants untreated with Rhizobium, phorate
suppressed nodule formation in the roots and stimulated nodule size and fresh
wieght.
