The Effects of Iron Application Foliarly at Different Times and Amounts on Agricultural Characteristics in Some Peanut Varieties

Abstract

This study was aimed to determine the effects of treated iron doses on agricultural characteristics by appyling foliar in some peanut varieties (NC-7 and Sultan). It was conducted at different times (flowering period and pod formation period) and doses (control, 400 kg da -1, 500 kg da -1, 600 kg da-1) in the farmer's field in the Göçmenler district in the Hardallık village of Kadirli, Osmaniye, in April and September of 2020. The study was arranged in a "Split-Split Plots Experiment Desing" with three replications, and varieties to the main parcels, treatment time to the sub-parcels, iron doses to the sub-sub-parcels, were treated. In the study, variety, dose, varietyxdose, timexdose, varietyxtimexdose interactions were found to be statistically important in pod yield. In terms of number of pod per plant, 100 pod weight, 100 seed weight; varietyxdose, timexdose, varietyxtimexdose interactions are important, however in the seed ratio these interactions turned out to be statistically insignificant except from variety. According to the results obtained, the highest pod yield was obtained as 521.1 kg da-1 from treatments of Sultan varieties in terms of varieties; it was obtained as 544.5 kg da -1 from pod formation period and 400 kg da -1 dose in the terms of varietyxtime interaction and it was obtained as 512.6 kg da -1 from 400 kg da-1treatment in terms of dose. As a result; for both periods in order to achieve high pod yield in peanut cultivation, 400 kg da -1 iron dose treatment and Sultan variety in Osmaniye conditions can be recommended.
