Effect of Irrigation and Tillage Systems on The Amount of Wasted Water and Net Profit of Broccoli Plants

Abstract

The experiment was carried out in the research field of the College of Agriculture and Forestry / University of Mosul / Tourist Forest Area, during the growing season (2023-2024). The experiment included studying the effect of two factors, the first factor: tillage systems (surface plowing and deep plowing) and the second factor included irrigation systems (drip irrigation system and flood irrigation system). Thus, the experiment included 4 treatments (2 × 2). The study was carried out in the field using a split-plot system within a completely randomized block design (RCBD), where tillage systems were placed in the main plots , and irrigation systems were placed in the Sub plots. The results can be summarized as follows:- A- The characteristics represented by the amount of water per 30 cm and the amount of wasted water were affected by the factor of tillage systems, as the surface tillage system showed significant superiority in these characteristics over the deep tillage system. B- The characteristics represented by characteristics of vegetative growth were affected by the factor of deep plowing systems, as the deep tillage system showed lower costs compared to the surface tillage system, which gave better values ​​in terms of net profit for the production process. The bilateral interaction treatment between the surface tillage system and the drip irrigation system showed the highest net profit for Characteristics of vegetative growth.
