Abstract / Excerpt:

Objectives: This study was conducted to evaluate the effects of varying levels of lime and phosphorus on (1) zinc as it affects dry matter and kernel yield of corn, (2) changes in P, Zn, and Ca contents of the soil and tissue, (3) the availability of zinc, and (4) the optimum lime-zinc combination for corn.

Methodology: Experimental method was used in this study. A detailed analysis of variance was computed in each case and treatment means were compared using Duncan's multiple range test.

Conclusions: (1) The original soil analysis for the two soils indicated that they are zinc deficient, (2) A mutual depressive effect of P and Zn on each other was observed. (3) The significance of the micronutrient zinc in plant growth and development has been demonstrated; that the addition of small amount of Zn resulted to a very high growth rate, (4) Exchangeable Ca decreased significantly with increasing P and not with Zn.
