10. Investigation of the irrigation regime of short-day onion, cultivar Radar by drip irrigation and treated with humatic acids

During 2004-2006 the experiment with short  day onion, cultivar Radar for investigation of the irrigation regime and nutrient intake by two kind of drip installations were carried out. The drip laterals were put in two rows. The distances between drippers were 10cm and 25cm. The biggest yield was 3718kg/dka at drip distance d=10cm and treated with Humustim (humatic acid). The coefficients of the yield response to water were K_y=1,92 and K_y=2,92 respectively of the trial period.
