Abstract
Greenhouse experiments were conducted to study the effects of pendimethalin on P uptake by soybean seedlings using 6 rates of the herbicide and 4 rates of fertilizer (0-8-0) P. Plants treated with 5 different rates of pendimethalin applied to the surface, exhibited short swollen hypocotyl, expanded and chlorotic cotyledons and inhibited root and shoot growth. All these plants wilted and died. Plants treated with pendimethalin at 1.0 kg/ha incorporated in the soil showed the highest amounts of P content while plants treated at the rate of 3.0 kg/ha showed the least amount of phosphorus. Phosphorus content of plants treated at the rate of 3.0 kg/ha and 1.5 kg/ha pendimethalin lower than that of the control. There was a general tendency for P uptake to increase fertilizer rate of 60 kg/ha.
