Manufacture and Testing an Automatic Sprinkler Riser in the Fixed Sprinkler Irrigation System Using Smart Irrigation and its Impact on the Performance of the System and Zea Maize Yield

Abstract

A field experiment was carried out with the aim of designing and manufacturing an automatic sprinkler riser for fixed sprinkler irrigation system and evaluated its impact on the system performance and the growth and production of Zea maize at Al-Raad Research Station located in the Akerkov area, 1 km north of the highway (Baghdad - Anbar) in silt clay loam soil for the agricultural season of 2021. Riser type included a regular straw, and a self-propelled riser with an inner tube, and a self-propelled riser with an external tube, and operating pressure included 1, 1.5 and 2 bar. Were used in this experiment., sprinkler discharge, sprinkler service area, plant height and plant yield. Were studied in this research Nested deign with a randomized complete block design (RCBD) with three replications, were used the least significant difference was used under the probability level of 0.05 (LSD0.05) for comparison in the averages of the coefficients of the experiment, the results showed the following an automatic sprinkler riser with the outer tube was significantly superior in obtaining the highest the highest moisture content of 37.29% and the highest value of the sprinkler service area amounted to 247.98 m2 and the highest yield of the crop was 6.38 tons.ha-1, while the self-propelled riser with inner tube outperformed in obtaining the highest value of plant height amounted to 189.67 cm, and it was noted that there was no significant difference between the risers used in the value of sprinkler discharge .The superiority of the operating pressure of 2 bar in obtaining the highest value of the highest value of the moisture content was 37.97, and the highest value of the sprinkler discharge was 33.07 liters. Min-1 and the highest value of the sprinkler service area was 367.71 m2, the highest plant height was 190.11 cm and the highest yield of the crop was 6.46 ton. ha-1 compared with other pressure. The interaction between the self-propelled riser with inner tube and the operating pressure of 2 bar was superior to obtaining the highest moisture content of 38.13%, and the highest discharge of the sprinkler was 33.40 liters.min-1 while the bilateral interaction between the self-propelled riser with an external tube and the operating pressure of 2 bar exceeded the highest value of the highest value of the sprinkler service area amounted to 377.69 m2, the highest height of the plant was 194.67 cm, and the highest yield of the crop was 6.89 ton. ha-1. The success of using the locally designed and manufactured an automatic sprinkler "self-rising" riser according to the plant's height and used in the fixed sprinkler irrigation system to irrigate the maize crop.
