اختبار أداء المرش الآلي العمودي المصمّم محلياً لرش أشجار البساتين مقارنةً مع أداء المرش التقليدي المحمول

Abstract

The research was carried out in May 2025 in the (Agricultural Nursery) area in Tartous Governorate in a seven-year-old citrus orchard with the aim of testing the performance of the locally designed vertical automatic sprinkler for spraying orchard trees compared to the performance of a conventional tractor-mounted sprinkler. The test was carried out by evaluating the performance of each sprinkler through some performance indicators, namely: pesticide consumption rate, pesticide use efficiency, overlap, practical productivity, and field efficiency. The results showed that the designed sprinkler reduced pesticide consumption by up to (33.3%), which increased its use efficiency by (68.75%) for the designed sprinkler compared to the conventional sprinkler (32.6%). The overlap decreased by up to (10%) for the locally designed sprinkler compared to the overlap ratio for the conventional sprinkler, which reached (35%). The average productivity of the locally designed sprinkler was (140 tr/h) and for the conventional sprinkler (120 tr/h). These results show that the designed sprinkler provides improved performance in terms of reducing spraying losses and increasing Productivity and improved pesticide consumption efficiency, making it more suitable for use in orchards compared to traditional sprayers.
