1. Effect of Using Different Formulations of Fertilizers on Stomatal Conductance, Leaf Chlorophyll Fluorescence, Growth and Yield of Table Grapes Crops Grown in the Northeast of Morocco

Table grapes (Vitis vinefera) present an important crop production in Morocco. The practice of tree fertilization is based on nitrogen, phosphorus, potassium, calcium, magnesium and micronutrients. Previous research demonstrated that using mixed fertilizers with microelements, organic matter and amino acid 4-5 times during the phonological stage improved growth and yield of different crops. The objective of a trial conducted in the region of “El GARET” on a production of 8-year-old... A. Essaihe , K. Aberkani
