Résumé:
The thesis questions the effect of boron-calcium on the evolution of the inflorescence, to achieve this, we even have a practical experimental study including a sample made up of 04 olive trees, where we chose the Sigoise variety. In our study, we used the experimental method of which the experimental tool was the essential tool, with the use of the boron-calcium solution in "Bca" form, by performing 03 different treatments: T1: 34 ml of boron-calcium / 17 liters of water T2: 42 ml of boron-calcium / 17 liters of water T 3: 85 ml of boron-calcium / 17 liters of water The research took place at the Technical Institute of Fruit Tree Cultivation in Mohammadia commune over a period of 02 months and 15 days (March 01-May 15). Research tells us that the effect of the boron-calcium solution on the phrenological stage of flower bud formation promotes the development of flowering, fruit set and therefore improved yield, reducing flower abortion as much as possible. due to physiological disturbances.
