摘要

Field experiment with long-day onion, cultivar BGS-196, for investigation of the irrigation regime by two kinds of drip installations and treatment with humic acids were carried out during 2008 - 2009. Double drip laterals were put in every bed. The distances between the drippers were 0.10 m and 0.25 m. The aims were to investigate the two types of drip irrigation and treatment with humic acids of 23.40% (trade name Humustim), e.g. four treatments replicated four times and arranged in a randomized complete block design. The beds were 1 m wide with experimental block area of 5 m~2 with two drip laterals. The timeof sowing was the same in 2008 and 2009 - at the beginning of March at seeding rate of10 kg.ha~(-1) or 200 plants per square meter. The treatment with humic acid was only onceat rate of 400 ml.ha~(-1) in the two type drip irrigation installations. The number of irrigations was 20 in 2008. The total amount of water applied with drippers spaced 0.10 m was 183.6 mm [1 836 m~3.ha~(-1)] and with drippers spaced 0.25 m it was 168.0mm [1 680 m~3.ha~(-1)]. The highest yield was by drip distance of 0.10 m. The yield was 42 820 kg. ha~(-1) in comparison with drip distance 0.25 m, where it was 29 230 kg.ha"1 in 2008.The production of onion by 0.10 m drip distance with humic acids was 32 000 kg. ha~(-1)in 2009. The lowest yield of onion was 27 050 kg. ha~(-1) by drip irrigation with distanceof 0.25 m without treatment with humic acids in 2009. The slopes of the lines of the relationship between relative yield reduction [1-Y/Y_(max)] and relative evapotranspiration deficit [1-ET/ET_(max)] showed that during 2008 and 2009 the yield coefficients of onion were K_y=2.63 and K_y=2.56, respectively. From the results it can be concluded that long-day onion, cultivar BGS-196 has got a yield coefficient bigger than 1.0, because it is from III group of crops, which are of the greatest extent dependant from the applied water.
