Abstract | ||||
Two field experiments were carried out during 2015/2016 and 2016/2017 winter seasons at El-Qantara East. Station, Desert Res. Center, North Sinai, Egypt to investigate the effect of some humic acid and organic compost fertilizer treatments on total carbohydrates, protein contents and protein yield/fad., of three bread wheat cultivars, grown under newly reclaimed sandy soil. Each experiment included 48 treatments which are the combinations between three wheat cultivars (Misr-1; Sakha-94 and Gemmeiza-11), four levels of humic acid (without humic acid; 1, 2 and 3 kg/fad.) and four levels of compost fertilizer (without compost, 5, 10 and 20 ton/fad.). The results revealed significant differences among wheat cultivars for protein percentage, protein yield and total carbohydrate contents in wheat grains. The results also showed that Misr-1 cultivar significantly surpassed the other two studied cultivars in carbohydrate percentage in both seasons. However, wheat cultivar Sakha-94 exceeded markedly the other two cultivars in protein percentage and protein yield. Application of either humic acid or compost fertilizer significantly enhanced protein percentage, protein yield and total carbohydrate content in wheat grains. The highest protein yield (238 in the 1st season and 270 kg/fad., in the 2nd one) was produced from Sakha-94 wheat cultivar with application of 20 ton/fad., compost in both seasons under Qantara East Area, North Sinai of Egypt. | ||||
