INTENSITAS PENGAIRAN DALAM UPAYA PENINGKATAN HASIL TANAMAN GANDUM

Abstrak

Wheat crops can grow and produce well on the island of Lombok and have opportunities for development, ranging from uplands to the lowlands about 400 m above sea level. This adaptation effort needs to be followed up with the development of cultivation technology, including proper irrigation. Watering is a fundamental factor in getting maximum yield in a cropland. This study aims to determine the exact intensity of water supply to obtain maximum grain yield. This research was conducted by experimental method in field using 3 irigation intensity on 4 varieties of grain Nias, Dewata, Gladius, and Estoc. High rainfall occurred during the experiment, so the soil was always wet throughout the experiment. Excessive rain that causes irrigation treatment does not affect the growth and yield of plants. Nias gave higher yield (2.62 t/ha) compared to Dewata varieties (1.68 t/ha), Estoc (1.41 t/ha) and Gladius (1.14 t/ha). Some growth and yield components are severely depressed due to these addictions, such as number of tillers, number of panicles and number of seeds / m², resulting in lower yields than expected.
