Abstract

The main purpose of this study was to determine the return and water physical and economic productivity in the production of horticultural products using drip irrigation system under research conditions in Horticultural Sciences Research Institute (HSRI) in Alborz province during 2016-2019. In this study, the return criteria including; net income, the percentage of sale return, and the percentage of investment return were used and physical and economic productivity analysis were used to measure the water productivity. According to the results, during 2017-2019, the average physical productivity of irrigation water in apple and pear genotypes was determined to be 2.75 and 1.7 kg/m3, respectively. The average economic productivity of water resulting from the gross profit of horticultural products in apple and pear genotypes was determined to be 39990.5 and 211486.7 Rials/m3 respectively, in Kamalshahr station. Results also showed that in 2016-2019, the average physical productivity of irrigation water in production of sour cherry, cherry, peach and apple genotypes was 1.08, 0.99, 1.69 and 1.61 kg/m3, respectively, and the average economic productivity of water based on gross profit of horticultural products in the genotypes of sour cherry, cherry, peach and apple were determined 106174.8, 95127.8, 25236.3 and 23011.2 Rials/m3, respectively, in Meshkindasht. The results of this study indicated the favorable state of the average economic productivity of water resulted from the profit of the production of apples and pears in Kamal Shahr station compared to the results of studies conducted in some parts of the country. However, the physical and economic productivity of water in the production of apple, pear and peach, has been generally much lower in these stations compared to the average resulted in some studied countries. So, investigation its reasons using comparative studies to increase water productivity in the production of these products at these research stations is recommended.
