Abstract

Recently, productivity of wheat is has been compromised due to low soil fertility despite the excessive use of mineral fertilizers. So, natural resources must be managed well by sustainable agriculture. Biofertilizers are a valuable alternative approach due to their potential for reducing mineral fertilizers and increasing yield. Two field experiments were conducted at Sids Agricultural Research Station, Beni-Suef Governorate, during 2021/2022 and 2022/2023, to study the effect of biofertilizers application with NPK at 25, 50, 75 and 100% of the recommended dose on growth, productivity and quality of three bread wheat varieties. (i.e., Sids 14, Sakha 95 and Misr 3). The results revealed significant
differences among varieties, fertilization treatments, individual or combined, and their interactions for yield-contributing
characteristics. Sids 14 variety recorded the highest values of number of tillers/plant, yield and its components and chemical properties. The treatment of 75% NPK+Bio. achieved the highest values in all traits studied except plant height. The interaction of Sids 14 variety with 75% NPK+Bio. showed the highest values of number of tillers/plant, yield and its components and chemical characters. From these results it could be economically recommend application biofertilizers along with 75% from recommended quantity of NPK on Sids 14 variety to achieve the maximum productivity of crop wheat.
