Özet
vii matter was obtained from 25 cm row spacing and 18 kg N/da applications. 3.2. soluable total dry matter was more affected by nitrogen application than sowing density, soluable total dry matter decreased with increasing nitrogen levels. 3.3. The effect of sowing density on ascorbic acid content was not significant. Ascorbic acid content decreased with increasing nitrogen doses. Ascorbic acid content of plant sinificantly increased upto 6 kg N/da application at all sowing desities and decreased thereafter. The highest ascorbic acid contents were obtained from 25 cm row spacing and 6 kg/da nitrogen level. 3.4. The effect of both sowing densities and nitrogen doses on chlorophyl a and chlorophyll b contents was significant, chlorophyll a and chlorophyll b were more effected by broadcasting than by sowing in rows. No statisticaly significant differences beetween chlorophyll a and chlorophyll b contents in relation with row spacings were detected. The highest chlorophyll a and chlorophyll b contents were obtained from broadcasting and 18 kg N/da application. The results show that both sowing density and nitrogen aplication affected plant growth, yield and quality although the effect of sowing density on quality was significant but inconsistant.VI broadcasting and 25 cm row spacing, and 12 kg N/da and 18 kg N/da nitrogen doses became more effective on the number of stems. 1.3. The effect of nitrogen was more than sowing densities on plant heigh. The highest plant heigh was obtained in 25 cm row spacing and 18 kg N/da nitrogen level. 1.4. Fresh and dry weight of leaves varied depending on treatments. Broadcasting and 25 cm row spacing increased both fresh and dry leaf weight more than 20 cm and 15 cm row spacings while 12 kg and 18 kg N/da applications were more effective than 0 kg and 6 kg N/da applications. 1.5. The highest fresh and dry stem weights were obtained with 25 cm row spacing and 18 kg N/da applications. Nitrogen levels became more affective than sowing density on fresh and dry weights of stems. But, this increase was obtained after a certain doses of nitrogen (6 kg N\da). 1.6. Fresh and dry weights of roots increased with increasing nitrogen application at all sowing densities. But, no significant differences occured between 0 kg N/da and 6 kg N/da treatments. 2. Yield: The highest yield was obtained from 15 cm row spacing and 18 kg N/da application while the lowest yield was obtained from 25 cm now spacing and 0 kg N/da application. 3. Quality: 3.1. The effect of nitrogen doses was stronger than sowing density on total dry matter. The highest total plant dryvii matter was obtained from 25 cm row spacing and 18 kg N/da applications. 3.2. soluable total dry matter was more affected by nitrogen application than sowing density, soluable total dry matter decreased with increasing nitrogen levels. 3.3.
