Abstract

Water is one of the natural resources and an important element to support the sustainability of life on earth. The existence of air that is on earth can only be used less than 1% of the existing fresh air or 0.01% of the total air on earth. The average water in the world is used 70% for agricultural needs, 8% for domestic needs and 22% for industrial needs. The objectives of this study are as follows: 1) To see the physical condition of the soil to be planted with maize in Savana Jaya Village. 2) To see the condition of the cropping pattern in the village of Savana Jaya agriculture. 3) To see the analysis of corn irrigation water needs from planting to harvesting with the Cropwat 8.0 program in Savana Jaya Village. 4) To see the analysis of relative yields of maize with Cropwat 8.0. The research was conducted in Savana Jaya Village, Waeapo District, Buru Regency, Maluku Province. Selection of location on the area of ​​land planted with maize. Data collection and research were carried out for 3 months, namely December 2019 - February 2020. The results showed that 1. Soil type Black clay Soil or black clay in the village of Savana Jaya with a total available moisture of 200 mm. m-1, the maximum infiltration rate is 30 mm. day-1, and the maximum depth that can penetrate the ground as deep as 900 cm. Pores containing 50% air, the maximum depth of air is 100 mm.meter-1. 2. The planting time for maize in Savana Jaya village is 4 times, namely January - March, April - June, July - September and October - December. 3. Corn commodities grown with a growing time of 60 days (variety BBA 228), with a crop coefficient of 0.30 - 1.20, with 30 days of tillage and planting, 20 days of vegetative phase, and 10 days of generative phase. 4. Rain efficiency during my MT is 62.1% and schedule efficiency -% with a time limit of 0.0% shows that this planting schedule is right for good plant growth. Although the efficiency of irrigant patients is invaluable because the rain that falls directly can meet the water needs of maize plants during MT I.
