This study aims to analyze rain data to determine the availability of water at the research location from rainfall, calculate the water needs of food crops, the needs of rice and secondary crops, analyze the water balance to calculate the comparison of availability and needs to determine the value of the surplus and minus balances and determine the appropriate cropping pattern. optimum to determine the right planting time and the right type of plant to be cultivated. The results showed that the average rainfall in Gunungkidul Regency during the 2014-2020 period was 167.9 mm, with a reliability level of 75%, the average effective rainfall was 66.74 mm. The average coefficient for rice plants is 1.08 and the coefficient for secondary crops is 0.82 so that the average water requirement for rice plants is 10.43 and that for secondary crops is 7.65. Based on water availability and plant water needs, an average water balance with 6 months of surplus includes November, December, January, February, March and April; and an average of 6 months of deficit covering May, June, July, August, September and October. The use of water pumps sourced from groundwater is a solution for farmers in maximizing land use and crop yields so that they can be planted 4 times a year with planting periods I and II planted with rice, III and IV planted with crops.
