Effect of fulvic acid, some micro-elements and micro-organisms on yield and its components, content fruits of macro-and micro- elements content of Zaghloul date palm [electronic resource].

Includes reference.

The present work was carried out in newly reclaimed land at the Experimental Station of the Faculty of Agriculture (Kalabshow and Zayan), Mansoura University, Dakahlia Governorate, Egypt. to study the effect of fulvic acid, some micro elements and microorganisms on yield and its components, fruits content of macro- and microelement of Zsghloul date palm. The obtained results indicated that fulvic acid applied at 83.33 ml / palm tree + microorganisms at 83.33 ml/ palm conjugation with micro elements at (3.12 gm from FeSo₄.7H₂o + 1.56 gm from ZnSo₄.7H₂o + 1.56 gm from MnSo₄.H₂o) as soil application / palm (T7) gave significant increase yieldl palm (174.16 and 169.33 kg), fruit weight (33.21 and 32.45 gm) and flesh weight (30.927 and 30.070 gm ), whereas the yield of T₁ control (96.16 and 92.23 kg/palm), fruit weight (20.34 and 19.63 gm) and flesh weight (18.47 and 17.95 gm) in both seasons of the study, respectively. All treatments of organic compounds extracts and microelements gave significant increase in the values of NPK and Fe, Zn and Mn in Date palm fruits as compared to control treatment in both seasons of the study.
