Abstract

This study was conducted to investigate the response of date palm (Phoenix dactylifera, L.) cv Zaghloul, to nine different fertilizer treatments i.e.  Control (1.5 N), full nitrogen (N) dose (100%) as mineral fertilizer (recommended rate), quarter organic fertilizers + 3/4 mineral, half-N dose as organic fertilizers + half as mineral, full N dose as organic fertilizer, quarter organic fertilizers + 3/4 mineral + bio-fertilizers (EM). half-N dose as organic fertilizers + half as mineral+ bio-fertilizers, full N dose as organic fertilizer+ bio-fertilizers and bio-fertilizers. The experimental design was complete randomize block design with three replicates under El Adlia, Blbas, Sharkia Governorate, Egypt during two successive years (2017 and 2018).
The results showed that full N dose as organic fertilizer+ bio-fertilizers gave the highest leaf number/palm, leaf length and leaf area index. Applied the full N dose as organic fertilizer+ bio-fertilizers gave the highest number of leaflets/leaf and leaflet length whereas; addition bio-fertilizers only produced the highest value of leaflet width. Also, our results clear that added half N dose as organic fertilizers + half as mineral enhanced the leaf chlorophyll content, but the addition full N dose as organic fertilizer+ bio-fertilizers increased carotenoids content.
Conclusively, from previous results, it can concluded that organic and bio-fertilizers enhancement all vegetative growth parameters of Zaghloul date palm cv. To reduce dates pollution, prefer replacement mineral fertilizer by organic and bio-fertilizers.
