Abstract
This study was conducted during two successive seasons (2022 and 2023) to know the effect of using organic compost fertilizer and effective microorganisms in improving productivity and fruit quality of Valencia orange trees for reducing NPK fertilizer Experiment were included as follows: (7.5, 15, 22.5, 30 kg compost / tree) and biovit fertilizer at a rate of 36 ml/tree of Valencia orange trees. Analysis of the data collected during the study showed that there was a statistical significance in increasing fruit quality different doses of organic and biological fertilization treatments. in this concern 15 kg  compost/tree + biovit 36 ml/tree had the best results and improved productivity and fruit quality  and it had a significant effect in reducing the added NPK chemical fertilizer by 50% in Valencia orange trees.
