Features of Onion Cultivation Technology With Drip Irrigation in the Arid Zone of Southern Kazakhstan
Year: 2025
Type: article
Abstract: The onion growing technology in the arid zone of southern Kazakhstan should consider the specific requirements of this crop for soil moisture throughout the growing season, considering the main phases of its development. The purpose of the research was to establish the features of the onion growing technology under drip irrigation with the determination of the optimal moisture threshold for the phases of plant development and the assessment of its effect on crop yields. Research method field experience in a specially designated experimental area. The authors have established that drip irrigation provides yields up to 103.2 t/ha, with a soil moisture threshold of 85% HB from germination to the start of bulb formation with a further decrease in soil moisture to a level of 75% HB for the formation phase - the beginning of bulb ripening and to a level of 70% HB before bulb ripening. This technology is recommended for use in farms in the south of Kazakhstan to increase productivity and product quality.
