The Effects of Dosages of Worm and Nitrogenphosphorus Fertilizers on Plant Growth of Hyacinthus Sp. In Si̇i̇rt Province, Turkey

Abstract

This research was carried out in order to determine the effects of worm fertilizer and nitrogenphosphorus fertilizer dosage differences on flowering of hyacinth as a bulbous ornamental plant from 2016 to 2017 in Siirt University, Turkey. Solid worm fertilizer was applied at dosages of 25 g/bulb (V1), 50 g/bulb (V2), 75 g/bulb (V3) and 2 kg/decare (NP1), 4 kg/decare (NP2), 8 kg/decare (NP3) Nitrogen-Phosphorus (NP) were applied during the growth of hyacinth (Hyacinthus orientalis L. cv. "Purple Star"). According to the results, the lowest (the earliest time) mean values of the first flowering time, full flowering time, and harvest time were obtained as 135.25 days, 136.54 days, and 137.70 days in V1 treatment, respectively. The highest mean value on leaf number (5.71), leaf length (128.21 mm), stalk thickness (13.50 mm), and floret diameter (28.14 mm) were determined in V1. The highest mean values belong to flower diameter (66.96 mm) and length (116.33 mm) were evaluated in V2 and V3, respectively. Among NP fertilizers, in NP1 the highest mean value on floret number (37.69) while in NP2 the highest mean value on floret length (26.76 mm) were obtained. The highest mean values on leaf diameter and plant height were found as 28.86 mm and 179.54 mm in NP3 treatment. As a result, it has been determined that the hyacinth can be grown with worm fertilization without chemical fertilizer use under ecological conditions of Siirt province. Considering the adverse effects of chemical fertilizers on the environment, it is proved that there are no statistically significant differences between them and the worm fertilizer, which is a bio-fertilizer.

“…Moreover, VC aids in the greater completion of root formation in plants, resulting in plants that take nutrients from the soil more readily and perform better in terms of growth [21] . Due to the presence of humic acid, which is a chemical similar to plant growth hormone, VC treatments have been proven in several studies to be able to improve plant growth parameters such as height, fruit yield, stem width, water content, flower width, leaf length, leaf number, and leaf area [22–30] .

“…[21] Due to the presence of humic acid, which is a chemical similar to plant growth hormone, VC treatments have been proven in several studies to be able to improve plant growth parameters such as height, fruit yield, stem width, water content, flower width, leaf length, leaf number, and leaf area. [22][23][24][25][26][27][28][29][30] Balmori et al explained that the foliar application of humic extract from VC at a 1 : 40 (v:v) on Allium sativum was the best treatment for growth parameters. They found that the humic substance increased the fruit quality and improved the bulb diameter.…”
