Phenological and Morphological Characteristics of Sun ower (Helianthus annuus L.) Species under Different Nitrogen Treatment Doses

Abstract

The present study was conducted to determine phenological and morphological characteristics of sun ower species (Isera, C-70165 and Teknosol) under different nitrogen treatment doses (0, 3, 6, 9, 12 and 15 kg N da-1) during the growing seasons of 2011 and 2012 under ecological conditions of Erzurum. Experiments were carried out in randomized full blocks design with three replications. Emergence, owering and ripening durations (days) were investigated as the phenological parameters and number of leaves, fresh and dry shoot yield (kg da-1) were investigated as morphological parameters. The emergence period were higher in the rst year and ripening periods, numbers of leaves, fresh and dry shoot yield were higher in the second year of the experiments. Except for owering period and number of leaves, nitrogen doses were signi cantly effective on the other parameters. The longest emergence period (13.8 gün) was observed in 12-15 kg da-1 N treatment. The longest ripening period (132.9 days) were observed in control treatment (with 0 kg da-1 N). The highest fresh and dry shoot yield (1161.6 kg da-1 and 363.3 kg da-1) were obtained from 15 kg da-1 N treatment. With regard to species, Isera had higher values in emergence period; C-70165 had higher number of leaves Teknosol had higher owering periods, ripening periods, fresh and dry shoot yield. Considering dry shoot yield, the species Teknosol may be recommended under 15 kg N da-1 dose.
