Abstract

THE EFFECTS OF LOCATION AND THE APPLICATION OF DIFFERENT MINERAL FERTILIZERS ON SEED YIELD AND QUALITY OF POT MARIGOLD (Calendula officinalis L.)

Abstract

The four-replicate trial with a local variety Domaći oranž (Local orange) was set up according to the randomised complete-block design in four locations (Gorobilje, Arilje, Pančevo and Kačarevo) and two variants of fertilizing (200 kg ha-1 KAN with 27 % of nitrogen and 400 kg ha-1 NPK 15:15:15) and the control without fertilizing. According to the three factorial analysis of variance for all observed traits it was determined that there were very significant differences within growing locations and fertilizing variants and their interaction (L x F). The highest seed yield (672.84 kg ha-1) was detected in the variant with 400 kg NPK ha-1. The significantly lower seed yield (579.84 kg ha-1) was obtained in the variant with KAN at the rate of 200 kg ha-1and the control variant (344.88 kg ha-1). The highest total seed germination of 91.84% and the 1000-seed weight (6.83 g) were obtained in the variant with 400 kg NPK ha-1. Total seed germination (85.87) and the 1000-seed weight (5.82 g) obtained in the control were significantly higher than total seed germination (83.31%) and the 1000-seed weight (5.42 g) obtained in the variant with 200 kg ha-1 KAN
