P. N. Takkar; M. S. Mann; R. L. Bansal; et al. Agronomy Journal 1976. doi:10.2134/agronj1976.00021962006800060024x
Other claims from this paper (12)
- Observation Corn responded optimally to P fertilization at 44 kg P/ha.
- Intervention effect High P supply beyond the optimum rate produced severe Zn deficiency symptoms in corn without added Zn.
- Intervention effect High P supply decreased grain and stover yields of corn.
- Intervention effect High P supply decreased Zn concentration in corn shoots.
- Intervention effect High P supply increased P concentration in corn shoots.
- Intervention effect Increased Zn supply significantly increased Zn concentration and uptake in corn.
- Intervention effect Increased Zn supply significantly increased growth and yield of corn.
- Intervention effect High rates of P fertilization (66 to 88 kg/ha) increased the Zn requirement of corn.
- Mechanism P reduced the rate of Zn entry into corn roots, inducing zinc deficiency.
- Association The P-Zn disorder in corn was better related to the P/Zn ratio in soil and plant parts than to P or Zn content.
- Method / resource P/Zn values above 7.5 in soil, 245 in grain, 130 in stover and 150 in leaves indicated severe Zn deficiency in corn.
- Method / resource P/Zn values of 4 to 7.5 in soil, 150 to 245 in grain, 90 to 130 in stover and 100 to 150 in leaves indicated moderate Zn deficiency or response in corn.
