INCREASING BEET PRODUCTION BY RECYCLING SOME ENVIRONMENTAL PRODUCTS

Abstract

The experiment was conducted in the fields belonging to the Department of Horticulture, College of Agricultural Engineering Sciences, University of Baghdad, at the Al-Jadriya Campus/ Station A, during the season of 2022-2023. The aim of the study was to investigate the improvement of beetroot plant growth through water fish irrigation and spraying water lens extract. The experiment consisted of two factors: the first factor was water fish irrigation with the following treatments: (A) Control treatment (river water with recommended fertilization), (B) Water fish irrigation at a concentration of 25%, (C) Water fish irrigation at a concentration of 50%, (D) Water fish irrigation at a concentration of 75%, and (E) Water fish irrigation at a concentration of 100%. The second factor was the spraying of lens extract with the following treatments: (T1) Control treatment, (T2) Spraying with a concentration of 0.25%, (T3) Spraying with a concentration of 0.50%, (T4) Spraying with a concentration of 0.75%, and (T5) Spraying with a concentration of 1%. The experiment was designed according to a randomized complete block design (RCBD) with three replications, resulting in a total of 75 treatments. The results showed that treatment E exhibited superior growth characteristics compared to the control treatment, with an increase in root weight of 71.0 g per root. The results also indicated that spraying lens extract at a concentration of 1% resulted in higher values for growth characteristics compared to the control treatment. Treatment T5 showed significant superiority in root weight compared to all other treatments, with a value of 64.4 g per root compared to the control treatment. The combined treatment ET4, involving Water fish and spraying water lens plant extract, showed significant improvement in most measured growth characteristics compared to the control treatment. Treatment ET5 exhibited the highest root weight, reaching 85.8 g per root compared to the control treatment.
