Abstract

Today, one of the biggest issues in the world is excessive water usage. One solution to this issue is the using aquaculture effluents to irrigate cropland, instead of their discarding to substitute directly using irrigated water supplemented with fertilizers. This study was conducted to determine the effects of fish pond irrigation and normal water irrigation on the development of two cultivars of maize crops. This experiment was conducted from June to November 2022 in the research field of the Fish Resources Department, Grdarasha Field, College of Agricultural Engineering Sciences, Salahaddin University, Erbil, Kurdistan Region. Two cultivars of maize (Glorya Zemun Polje and DKC 6664 Monsanto) were used in this study irrigated with two different sources of water (Normal water and Fish Pond water) in Factorial Randomized Complete Block Design, each with three replications. The plot area is about 7.5 m2 (3 m × 2.5 m). Every two weeks after emerges plant high, leaf area index, dry mass, tassel, and ear length were measured. The results showed that no significant (P>0.05) differences were observed among cultivars, source of water, and their interaction on plant height, leaf area index, dry mass, tassel and ear length, and grain yield parameters, except fish pond water significantly (P<0.05) increased leaf dry weight compared to the normal water at eight weeks after emerges. Also, the interaction between both cultivars with normal water significantly (P<0.05) increased the leaf area index compared to the interaction between cultivar two with fish pond water two weeks after emergence. This form of irrigation is important because it is organic, environmentally friendly, and a sustainable type of farming.
