Koefisien Keseragaman Dan Distribusi Kadar Air Tanah Sistem Irigasi Curah (Sprinkler Irrigation) Pada Budidaya Tanaman Stevia (Stevia rebaudiana B.)

Abstract

Sprinkler irrigation provides water to crops, similar to rainfall influenced by the compressive force given, and is expected to improve or maintain soil conditions in a field capacity state. However, its application faces several challenges, such as providing water to plants. This study aimed to determine Sprinkler irrigation's Coefficient of Uniformity (CU), the soil water content in Sprinkler irrigation, and the Stevia crop coefficient (Kc) value. The study results showed that Sprinkler irrigation increased soil water content at a depth of 0 – 60 cm, with the total water requirement for Stevia plants being 279.8 mm until the plants were 60 days old. Furthermore, the values for the Stevia crop coefficient (Kc) increased with the plant's growth stages, demonstrating the importance of regular monitoring and adjusting irrigation practices to ensure optimal crop growth. In conclusion, the study demonstrates the effectiveness of Sprinkler irrigation in increasing soil water content and determining the appropriate water requirement and Kc value for Stevia crops, which can help farmers manage and optimize their irrigation practices.
