Abstract EN

The study was conducted during the seasons 2019 and 2020 on pistachio trees* the Ashouri variety* aged (33) years* which were planted at the Agricultural Scientific Research Center in Hama (Syria) with the aim of studying the effect of pistachio wastes compost and organic fertilizers on quantitative and qualitative productivity indicators.

This study included four treatments in addition to the control, using pistachio wastes compost (PW) to fertilize pistachio trees at a rate (15 kg / tree) and pistachio wastes compost with organic fertilizer (PW + OM) at a rate (7.5 + 15 kg / tree) and fertilizer Organic (OM) at a rate of (30 kg / tree) compared to the chemical fertilizer treatment (TNPK) according to what is followed by the farmer* and with the presence of a control without any fertilizer addition (T0)* the experiment was designed by designing complete randomized sectors.

The organic fertilization treatments and pistachio wastes compost showed significant superiority in the first season* as the treatment (OM) showed a significant superiority with the production quantity (5.70) kg / tree( over all treatments, and the treatment (PW + OM) showed significant differences on all treatments with the lowest nut blanking percent and the highest percentage Half kernel nuts (8.68* 95.54)%* respectively, and the treatment (Tnpk) significantly outperformed the rest of the treatments with the highest weight of wet fruit and dry kernel (2.75* 0.49 g).

In the second season, all fertilization treatments were significantly superior to the control, and without differences between them and the highest production was in Treatment (OM and PW + OM) with the highest productivity (23.6* 21.6) kg / tree* respectively* and no significant differences were shown for the rest of the studied indicators.

According to these results, fertilization with pistachio wastes compost and organic fertilizer (PW + OM) with rate (7.5 + 15 kg/tree) is economically and environmentally beneficial to obtain quantitative and qualitative characteristics for the production of pistachio trees, var.
