Irrigation dynamics of laser spray and rain port systems

Water is essential for agricultural production, and modern irrigation practices emphasize
feeding the root rather than merely the crop. Recent advancements, particularly in micro-irrigation
systems like laser spray and rain port irrigation, have shown improved efficacy over traditional
methods. This research paper investigates the performance and irrigation dynamics of two emerging
micro irrigation systems, laser spray, and rain port systems, in enhancing water use efficiency in
agricultural practices within Andhra Pradesh, India. The study is anchored in the context of the
increasing importance of micro micro-irrigation technologies to improve crop productivity, especially
in rainfed conditions. Experimental trials were conducted at two agricultural research stations,
Ananthapuramu and Reddipalli, focusing on various performance indicators including Christiansen
Uniformity Coefficient, Distribution Uniformity, Coefficient of Variation, and Depth of Irrigation.
Results indicate that the rain port system exhibits a higher uniformity and lower coefficient of
variation compared to the laser spray system, with mean uniformity coefficients of 86.98% and
79.34% respectively. The distribution uniformity showed that the rain port system maintains better
performance consistency across different operational conditions. Furthermore, the study highlights the
significance of operational pressure and wind speed on irrigation efficacy, noting that the rain port
system's design allows for better water distribution and efficiency in diverse cropping systems. This
research underscores the potential of advanced micro micro-irrigation systems in optimizing water
usage and enhancing agricultural productivity, advocating for their wider adoption in sustainable
farming practices.
