This study was carried out during two successive seasons 2021 and 2022 on the Thirteenth-year-old Mango (Mangifera indica L.). cv. Keit cultivar trees grafted on sokary stone and grown in Al-Busaili - Central Laboratory for Agricultural Climate of the Agricultural Research Center at the North West of the Nile Delta, Rashid Center, Beheira governorate, Egypt. The trees are grown in a greenhouse to impact the soil application of farmyard manure, pigeon wilt and humic acid on vegetative growth, yield and fruit quality of “Kiet" mango cultivar. The distance between trees was 2.0 m and the distance between rows is 2.0 meters. This factorial experiment consisted of thirteen treatments arranged in a Randomized Complete Block Design (RCBD) design with five replicates for each treatment and one tree for each replicate. The treatment consisted of 13 treatments (control, farmyard (5, 10 and 15kg), mixture of farmyard with pigeon wilt and humic acid). Results showed that the treatment of OM at 15 kg + 1/2 kg HA+ 3.5 kg Pio. recorded the best values of fruit weight, the number of fruit and yield/plant, physical characters i.e. (fruit length, fruit width, pulp weight and fruit firmness), and all chemical compositions i.e. (TSS, TSS/ acidity, vitamin C content, total sugars, reducing sugar and non-reducing sugar percentage), as compared with the control treatment which recorded the minimum values of this studied characters, during both seasons.
