Effects of Zinc Application on Yield and Some Yield Components in Peanut (Arachis hypogaea) in the Easthern Mediterranean Region

The effect of soil and foliar Zn fertilization on two varieties of peanut's (Arachis hypogaea) yield and some yield components were examined in this study. Soil applications of Zn doses were 0, 10, 20 and 40 kg ha(-1) whereas 0, 0.5, 1 and 1.5 kg ha(-1) Zn were sprayed to leaves. Applications of dose amounts of Zn lead to remarkable increase in yield and 100-seed weight. The effect of Zn treatment found to be statistically important at P<0.01 levels. The highest yield was obtained at COM variety as 6580.0 kg ha(-1) with 0.5 kg ha(-1) Zn foliar application. The lowest yield was measured at NC-7 variety's control plot with 3660.0 kg ha(-1) in 2007. Foliar application Zn was statistically determined to be important to NC-7 variety peanut's grain Zn concentration at P<0.05 levels in each year. The economic analyses revealed that 0.5 kg ha(-1) foliar application of Zn provided maximum profit with 10271.2 USD Dollars ha(-1).
