Evaluation of The Biological Response of Neem (Azadirachta Indica) Spraying With Proline, and Addition of Mycorrhizal Fungi

Abstract

This study was conducted using plastic pots of 15 kg pot capacity for the 2019 agricultural season in a private nursery in Ramadi city / Al-Anbar governorate, with the aim of studying the effect of nano-organic fertilizer and proline acid on some vegetative growth characteristics of Neem trees (Azadirachta indica). Field experiment included three proline concentrations were (0, 50 and 100) mg.L−1 and three concentrations levels of Mycorrhizae were 0, 2 and 4 g per pot contains 15 kg of soil. Data averages were compared by using the Lowest Significant Difference (L.S.D) at a probability level of 0.05. The overlap between the study factors led to a clear increase in all the studied traits and the trees that were treated with the study factors outperformed them.
