Influence of sowing date and organic fertilizers on productivity of Moringa oleifera plant under Aswan governorate conditions, Egypt

Abstract

An experiment field were carried out in Aswan governorate, Egypt, during the two consecutive of seasons 20.17 and 2018 to evaluate the effect of organic fertilization and sowing date on: plant vegetation, yield and leaves chemical constituents of moringa plant. The organic fertilizers were farmyard manure (FYM), compost (COM) and poultry manure (PM). The results showed that, generally, organic fertilization improved growth characters, yield as well as N, P and K percentages in leaves. Whereas, the highest N, P and K contents leave were recorded when poultry manure added at 10 m 3 /feddan rate (feddan = 4200 m² = 0.420 hectares = 1.037 acres). .
