Effects of Humic Acid on the Germination Traits of Pumpkin Seeds under Cadmium Stress
The study tackled the effect of humic acid and cadmium concentrations on the pumpkin seed germination ezall fly spray characteristics throughout were studied.Treatments were cadmium concentrations on three levels: 0, 100 and 200 ppm and humic acid concentration of 0, 100, 200, 300 and 400 mg lit-1.Results showed that interaction of humic acid and c
