| dc.description.abstract | A field test on the influence of different sources and rates of Zn on the yield, and Zn and P compositions of peanuts (var. Starr) was conducted on an alkaline sandy soil where peanuts were suspected to be Zn deficient. At low rates of application, the Zn chelates (Zn EDTA, Zn NTA, Zn Reax, and Zn Rayplex) gave significantly higher yields than their non-chelated counterparts (ZnSO₄, Zn Frit and Trend). Zn chelates applied at about 1 kg Zn/ha gave yields near 3,232 kg/ha of unshelled peanuts; whereas, from ZnSO₄ about 30 kg Zn/ha were required to attain equivalent yields. The highest rate of ZnSO₄ (90 kg Zn/ha) sharply depressed yield, presumably due to Zn toxicity. Zn Frit and Trend, which were applied only at 3 kg Zn/ha, gave yields similar to ZnSO₄ when applied at the same rate. ... | en |
