Abstract
A pot experiment was carried out at the Faculty of Agricultural Engineering, University of Aleppo, during the 2016/2017 and 2017/2018 seasons in order to study the efficiency of fertilization by Fe and Cu on the productivity of lentil, variety (Idleb1) on calcareous soil. Completely randomized block design was used with five treatments: Copper sulfate and copper chelate with application level of (2 kg/ha), iron sulfate and iron chelate with concentration of (5 kg/ha), and control. Lentil plants had significant response to Fe and Cu when added as chelate. Fe concentrations in soil were 5.21, 5.04, 4.39 ppm for iron chelate, iron sulfate and copper chelate respectively, these treatments had superiority comparing with control. Highest concentration for Cu in soil was 1.18 ppm at copper chelate treatment, and it had a significant difference with other treatments. The concentration of Fe in plant tissues varied between (29.98-33.34 ppm) at first season and between (29.46-33.99 ppm) at second season. Whereas, the concentration of Cu in plant tissues varied between (20.59-25.25 ppm) at first season and between (20.42-25.46 ppm) at second season. The concentration of Fe in seed varied between (34.45-38.32 ppm) at first season and between (34.02-38.13 ppm) at second season. Whereas, the concentration of Cu in seed varied between (18.35-23.16 ppm) at first season and between (18.15-23.20 ppm) at second season. Also, the mean of two seasons showed highest increasing in biological yield (45.6%, 23.8%) for application of Fe chelates and Cu chelates respectively comparing with control. The grain yield increased by ratio 9.3, 13.6, 27.1 and 32.9% for Cu sulfate, Fe sulfate, Cu chelate and Fe chelate respectively compared with control.
