Response of Two Peanut Varieties to Foliar Spray of Some Micronutrients and Sulphur Application under East of El-Ewinat Conditions

Two field experiments were conducted at East of El-Ewinate Agricultural Research Station, New Valley, Egypt during 2013 and 2014 seasons to investigate the response of two peanut varieties to the foliar application of some micronutrients (Fe, Zn and Mn) and sulphur addition. A randomized complete block design (RCBD) using a split- split-plot arrangement with three replications was used. Seven combinations of Fe, Zn and Mn were randomly allocated in the main plots. Two elemental sulphur levels (200 and 400 kg fed.^-1) were randomly assigned in the sub-plots, as well as two peanut varieties (Giza-6 and Sohag-110) were arranged in the sub-sub-plots.
The obtained results showed that, the peanut varieties varied significantly in most studied traits except the shelling percentage in both seasons. Sohag-110 variety surpassed Giza-6 in the most studied traits of peanut crop. The foliar application of micronutrient treatments had a significant influence on all studied traits of peanut crop in both growing seasons. Also, the interaction of varieties and the micronutrients foliar application showed a significant impact on some studied traits compared to the control. The yield and its attributes were significantly affected when sulphur and micronutrient treatments were applied. The highest mean values of most studied traits were obtained by applying 400 kg fed.^-1 of sulphur with adding Fe +Zn + Mn treatment as a foliar spray. Moreover, the highest mean values of yield and its attributes as well as oil yield were obtained by adding 400 Kg fed.^-1 of sulphur and spraying Sohag-110 variety of peanut crop with Fe + Zn + Mn treatment.
