Abstract

A field experiment was carried out to evaluate the effect of different irrigation systems on some soil physical properties, growth and yield of cotton crop in one of the experimental fields of the College of Agricultural Engineering Sciences, University of Baghdad in Jadiriyah / Baghdad in a sandy loam soil for the spring agricultural season 2021. Irrigation systems included surface drip irrigation, subsurface drip irrigation and furrow Irrigation systems as a control treatment were studied in this experiment. Soil moisture content, soil bulk density, soil moisture homogeneity coefficient, plant height and plant yield were measured in this study. Nested design was used under randomized complete block design (RCBD) with three replications. The superiority of the subsurface drip irrigation system (LSD _{= 0.05}) in obtaining the highest soil moisture content stood 15.01%, the lowest soil bulk density stood 1.28 g cm^-3, the highest soil homogeneous Humidity Factor stood 95.73%, the highest plant height stood 121.75 cm, and the highest number of boll branches stood 13.10 branches plant^-1 and the highest yield stood 141.98 g plant^-1 Compared with surface drip irrigation system. Furrow irrigation excelled in obtaining the highest soil moisture content stood 20.51%, the highest plant height reaching 135.50 cm, and the highest number of boll branches reached 16.79 branches plant^-1 and the highest yield reaching 196.125 g plant^-1. Results obtained of this study improved our understanding regarding irrigation of cotton crop under arid and semi-arid conditions
