| Résumé: | In Moroccan oases, the major challenge for modern date palm production is mainly
focused on increasing yield and quality of fruits as well as sustainability of the arid climate
zones. The aim of this study is to evaluate effect of two organic biostimulants on yield and
quality of dates.
The experimental trial was conducted out, in a conventional farm of palm date
(Phoenix datylifera L.) cv. ‘Mejhoul’ during 2016 season, under pedoclimatic conditions of
Tinejdad, Errachidia region, Morocco. To this end, the application of two biostimulants
was performed by spraying and repeated three different times after pollination (on late
April, beginning-July and mid-August). Three variants were compared (Control, Protifert
LMW 6.3 and Vitazyme®), the experimental design is completely random blocks with
three repetitions and three trees per variant (a total of 27 palm trees). Measurements were
made on yield and pomological traits of fruits. In addition, reducing sugars quantification
was made by HPLC.
Results obtained showed that treatment affected significantly all of the studied
parameters. Indeed, Protifert LMW 6.3 increased the yield per tree by 18 and
27%compared to Vitazyme and Control, respectively. As for fruit dimensions, Protifer
tspawned longer dates over than Vitazyme® and Control, whereas both biostimulants
induced fruit of the same width but larger compared to Control. In addition, fruit weight
Optimization of Quali-Quantitative Production of Date Palm CV.
‘Mejhoul’ in Moroccan Oases by Biostimulants Application ranged from a maximum of 14.50 ± 0.13 g recorded by Protifert LMW 6.3 and a minimum
of 10.32 ± 0.15 g observed in the Control. However, fruits of treated trees by Vitazyme®
were richer in flesh (92.62%) compared to those obtained by untreated trees (90.78%).
Glucose and fructose content engendered by Vitazyme were slightly decreased in
comparison with Protifert and Control. |
