Analysis of Productivity and Water Use Efficiency in Horticultural Crops in Dry Land Based on Microirrigation Technology

Abstract

Water scarcity is a major challenge in the development of agriculture in dry land, especially for horticultural crops that require regular and efficient water supply. Micro-irrigation technology, such as drip irrigation systems, is one of the innovations that can overcome this problem by providing water directly to the root zone in the right and controlled amount. This study aims to analyze the impact of the application of microirrigation technology on the productivity and efficiency of water use in the cultivation of red chili (Capsicum annuum) and tomato (Solanum lycopersicum) plants in dry land. The method used is a field experiment with two main treatments, namely conventional irrigation (manual) and drip microirrigation. The observed parameters included the volume of water used, water use efficiency, plant height, number of fruits per plant, and yield per hectare. The results showed that microirrigation was able to save water by up to 47.6% and increase water use efficiency by more than 80% compared to conventional irrigation methods. In addition, microirrigation also results in significant increases in crop productivity, with higher yields on both commodities. These findings show that microirrigation technology is very effective in increasing horticultural agricultural yields on dry land while maintaining water resource efficiency. The implementation of this system has the potential to support agriculture that is more sustainable and adaptive to climate change, and can be a strategic solution in the development of marginal agricultural areas in Indonesia.
