Abstract

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 .
