Economical Analysis of Different Drip Irrigated Sugar Beet Production

This research was designated for 2012-2013 growing season and aimed to research effects of deficit drip irrigation and nitrogen levels on sugar beet production cost, gross and net income. The highest energy use was determined as 467.9 L/ha in full irrigation of FI treatment since it was the highest water applied treatment as 8311 m 3 /ha. Energy cost per ha was found the greatest as about 1048 $/ha in FI and increase of applied water resulted higher energy cost. Sugar beet production cost for two years average was calculated as about 1160 $/ha. Amount of irrigation water and nitrogen level was the highest in FIN1 (full irrigation with 160 kg N/ha) treatment and in those plots applied water and nitrogen level was the highest so that total annual cost was the greatest in FIN1 treatment as about 3238 $/ha. The lowest one was obtained from APRD50N3 (Alternative Partial Root Drying that is condition of 50% less water application from F1with 80 kg N/ha) treatment as about 2613 $/ha and FPRD50N3 (Fixed Partial Root Drying that is condition of 50% less water application from FI with 80 kg N/ha) treatment as 2350 $/ha. By comparison to FI, CDI75 (25% less water application from FI) resulted only 8.4% low income. Thus, CDI75 can be recommended for better income as well as efficient water use in agriculture. In regions where the water resources are limited, PRD is a viable irrigation alternative to increase water productivity as well as farmer income under well management.
