The effect of different seed quantities on plant characteristics and quality of phacelia (Phacelia tanacetifolia Bentham)

This research was carried out to determine the effects of different seed quantities (1.0, 1.5, 2.0 and 2.5 kg da-1) on some plant characters and quality characteristics on phacelia, in the province of ？anl？urfa, Turkey in 2016-2017 growing season. The experiment was in randomized complete block design with 4 replications. According to the study results, plant height ranged from 48.5 to 60.2 cm, green herbage yield 2191.5-3113.2 kg da-1, dry herbage yield 403.4-508.7 kg da-1 and crude protein 11.5-12.9% were determined. Based on the results obtained in the research, it was determined that the use of 1.5 kg da-1 seeding could be suitable to obtain high yield and good quality in the climate and soil conditions of ？anl？urfa province
