Response of Mango Trees to Mineral, Bio-Organic Fertilizers and Growth Stimulants

This investigation was carried out at privet farm, Ismailia Governorate during 2019 and 2020 seasons. The effect of mineral (NPK) soil application either alone or in combination with organic (compost), some soil bio-stimulants (Phosphorein, Nitrobein and Potasein) and foliar spray with potassium silicate at (5 ml/liter) and bento cide at 10 g/liter as growth stimulants were investigated through studying their effect on fruiting aspectsandfruit characteristics of mango trees. Results showed that, all investigated NPK soil application in mineral form, organic (compost) fertilizers, bio-fertilizers and some foliar nutrients (Bento cide and potassium silicate) resulted in significant effect, however, the fertilization with NPK in mineral form at 50% level + organic (compost) fertilizer at 50% level coupled with either bento cide at 10 g/liter or potassium silicate at 5 ml/liter were the most effective treatments for increasing fruiting aspects and fruit characteristics of mango trees Sedika cv.
