Abstract EN

This study was conducted in a private orchards located in Al-Nashwa sub-district, north of Basrah Governorate – Iraq.

The aim of this experiment was to study the effect of bio and nano fertilizers and method of adding in physiological and productivity of date palm fruits.

This study included twelve treatments, which are the combination between three biocont-T and Optimus plus fertilizers, as well as the control treatment and three methods of addition: ground, spray, and ground + spray.

The results showed, the combined treatment of biocont - T + Optimus plus was significantly higher in most studied traits, as it recorded the highest value of the fruit weight, the percentage of the fruit set, the percentage fruit ripening, the average bunch weight, and the total yield of fruits, which were recorded (9.35) gm, (78.40)%, (83.62)%, (9.271) kg, (64.90) kg for the studied traits respectively, while the control treatment recorded the lowest values for the studied traits (6.10) gm, (64.52)%, (59.62)%, (7.87) kg, (55.12) kg, respectively.

Whereas, the lowest percentage of fruits drop was (13.46)%, while the highest percentage (17.23)% was recorded in control treatment.

The results also showed the superiority of the spraying method with the ground addition significantly in recording the highest values for the percentage of the fruit set, the ripening percentage, weight of the fruit, and the total yield, which recorded (37.91)%, (74.95)%, (8.78) kg, (61.49) palm.

kg-1 , and the percentage of fruit drop decreased (15.00%).

The results also showed that the combined between the two study factors gave a significant superiority in most of the studied characteristics
