Yields of watermelon cv. ‘Bingo’ on the very light soil as dependent on fertiga-tion of nitrogen by drip irrigation system and the way of seedling production

key words: drip irrigation, fertigation, the way of seedling production, very light soil, watermelon

Summary:

The effect of drip fertigation and the two ways of seedling production on the yields of cv. ‘Bingo' was determined in the field experiment carried out in the year 2008 on a very light soil at Kruszyn Krajeński near Bydgoszcz. The experiments were run in a split-plot system with four replications. Two different factors were compared. The first row factor - drip fertigation, was used in the two following treatments: KP - drip irrigation + standard N-fertilization (control),KF - drip irrigation + N-fertigation 3 times during the vegetation season. Fertiga-tion was conducted with the use of proportional mixing dispenser. The second row factor was the light used during the seedling production: S - sunny light (greenhouse, control), F - artificial light - fitotron (lamps). It was found that the fertigation significantly increased marketable fruit yield from 40,1 to 51,0 t.ha-1 (by 10,9 t.ha-1 i.e. by 27 %). Yields of plants from seedlings produced under conditions of sunny light in greenhouse (control) - treatment (S)(48,1 t .ha-1), were signifi-cantly higher than those obtained from seedlings produced in fitotron under artifi-cial light (43,0 t .ha-1). The highest yields (56,0 t .ha-1) were obtained from plants from seedlings produced in greenhouse grown under fertigation.
