Description Soybean (Glicine max) has the potential to be developed because it cannot only be processed into foodstuffs but also become livestock feed. In addition to using technology, enhancement of crop production can be done by looking at water availability and pay attention to the weather factors, especially to increase crop intensity. This research aims to determine the crop water requirements based on the agroclimatic zone. The quantitative descriptive analysis and data processing were conducted using the Cropwat model. This model was created by FAO specialists to provides an opportunity for automation of all the necessary calculations for evapotranspiration determination. Cropwat is an easy-to-operate software that can minimize human error. Climate classification was identified based on precipitation data in Jambi province respectively in Muaro Jambi Regency at Sultan Thaha Station, Jambi Palmerah, and Depati Parbu. The agroclimatic zone for those areas, respectively, are D1, D2, and E2. Based on the rainfall, all three districts are feasible for soybean cultivation with average rainfall between 127.11 mm – 192.51 mm per month. The amount of crop water requirements is also an essential factor for cultivating a plant so that the water can be administered according to the needs of plants and can provide optimal production. Based on water balance, the surplus in Muaro Jambi Regency Jambi Province occurs in January, February, March, April, September, October and December. East Tanjung Jabung Regency surplus is in January, February, March and April. West Tanjung Jabung Regency surplus occurs in January, February, March, October, November and December. The results of this calculation indicate that Jambi Province has the potential to cultivate soybean plants because they have sufficient water availability.
Kedelai (Glicine max) berpotensi untuk dikembangkan karena tidak hanya dapat diolah menjadi bahan pangan tetapi juga menjadi pakan ternak. Selain pemanfaatan teknologi, peningkatan produksi tanaman kedelai dapat dilakukan dengan memperhatikan ketersediaan air dan faktor cuaca terutama untuk meningkatkan intensitas tanaman. Penelitian ini bertujuan untuk mengetahui kebutuhan air tanaman berdasarkan zona agroklimat. Analisis deskriptif kuantitatif dan pengolahan data dilakukan dengan model Cropwat. Model ini dibuat oleh FAO untuk menentukan perhitungan evapotranspirasi dan perhitungan kebutuhan air tanaman di seluruh dunia secara otomatis. Cropwat merupakan salah satu model perangkat lunak yang mudah untuk dioperasikan dan dapat meminimalisir kesalahan manusia. Klasifikasi iklim diidentifikasi berdasarkan data curah hujan di Provinsi Jambi yaitu di Kabupaten Muaro Jambi di Stasiun Sultan Thaha, Palmerah Jambi, dan Depati Parbu. Zona agroklimat untuk setiap wilayah tersebut berturut-turut adalah D1, D2, dan E2. Berdasarkan curah hujan, ketiga kabupaten tersebut layak untuk budidaya kedelai karna memiliki curah hujan rata-rata 127,11 mm - 192,51 mm per bulan. Banyaknya kebutuhan air tanaman juga menjadi faktor esensial dalam pembudidayaan tanaman agar air dapat tertata sesuai dengan kebutuhan tanaman dan dapat memberikan produksi yang optimal. Berdasarkan neraca air, surplus di Kabupaten Muaro Jambi Provinsi Jambi terjadi pada bulan Januari, Februari, Maret, April, September, Oktober dan Desember. Kabupaten Tanjung Jabung Timur mengalami surplus pada bulan Januari, Februari, Maret dan April. Kabupaten Tanjung Jabung Barat surplus terjadi pada bulan Januari, Februari, Maret, Oktober, November dan Desember. Hasil perhitungan ini menunjukkan bahwa Provinsi Jambi berpotensi untuk dibudidayakan tanaman kedelai karena memiliki ketersediaan air yang cukup.
