This study aimed to appraise the impact of replacing part of the recommended dose of mineral fertilizers (NPK) for wheat (Giza171) with bio and organic fertilizers on some growth parameters, avaliable (NPK) in the yield grains, and phytochemicals (chlorophyll a, b, and carotenoids)at vegetative stage.
A pot experiment was done in sandy saline soil during the winter season of 2020/2021 at the agricultural station of Kafr EL- Hamam, Al-Sharkia Governorate, Egypt, the farm is located at 30.59 longitudes and 30.41 latitudes. The experiment comprised fourteen treatments, including minerals, compost or biofertilizers alone, or a mixture of three factors of fertilizers in triplicates placed in a randomized block design. The results revealed that the determined yield attributes of wheat were significantly increased by receiving 90% of the recommended dose (RD) with compost and the inoculation with salinity durable bacteria (T13). A similar trend was observed by the recommended dose of NPK(T2) followed by 75% mineral fertilizers combined with compost, and a mixture of bacteria strains(T12), then 60% mineral fertilizers plus compost and a mixture of bacteria strains(T11).
