Abstract

Considering the drought crisis and high consumption of water in paddy fields, it is useful to present strategies in order to increase irrigation efficiencies. However, one of the methods to increase productivity in the agricultural development of cropping and ratoon culture that has an important role in the economy of rural households. Therefore, it is necessary to determine the amount of water needed for the second cultivation of rice and the cultivation of ratoon for water resources planning. This study was conducted in Mazandaran province, Sari. The Local Tarom early varieties during two crop seasons in 1395 and 1396 years of regional ratoon also was conducted in 1396. To measure the input and output flows, triangular overflow was applied to the treatments and three Lysimeters were used to determine the water requirement of the fields. Water use efficiency and water productivity were investigated in each treatment season. The results showed that the highest consumption efficiency was measured at 61% in ratoon cultivation. The water use efficiency in ratoon cultivation increased by 39% compared with the second cultivation of 1395 and 42% compared to the second cultivation of 1396. Water productivity in the second cultivation of 1395 and 1396 and ratoon cultivation in 1396 was 51%, 33% and 40%, respectively. Therefore, in areas with enough rainfall during the second cultivation and cultivation of ratoon, second cultivation of rice and rattan culture can be recommended.
