Growing}, volume={5}, url={https://www.ajouronline.com/index.php/AJAFS/article/view/4710}, DOI={10.24203/ajafs.v5i2.4710}, abstractNote={&lt;p&gt;This study were carried out to of different sowing time in order to determine the effects on plant growth of kohlrabi cultivation under Samsun condaitions during the autumn growing periods in unheated greenhouse. Four different seed sowing times (1&lt;sup&gt;st &lt;/sup&gt;September, 15&lt;sup&gt;th&lt;/sup&gt; September 1&lt;sup&gt;st&lt;/sup&gt; October, 15&lt;sup&gt;th&lt;/sup&gt; October), two different kohlrabi cultivars (Kolibri F&lt;sub&gt;1&lt;/sub&gt; and Korist F&lt;sub&gt;1&lt;/sub&gt;) and two mulch applications (mulch covered and uncovered) were used in this study.&lt;/p&gt;&lt;p&gt;The plant growth parameters analyzed (total plant dry weight, leaf area ratio, specific leaf area, net assimilation rate and relative growth rate) were found statistically significant (p&amp;lt;0.05). The highest total plant dry weight (114.1 g) was obtained from mulch application and 1&lt;sup&gt;st&lt;/sup&gt; September seed sowing time. The highest leaf area ratio value were obtained in both mulch application the Kolibri F1 variety grown on October 15&lt;sup&gt;th&lt;/sup&gt;. The highest net assimilation rate (0.65 g cm&lt;sup&gt;-2&lt;/sup&gt; day&lt;sup&gt;-1&lt;/sup&gt;*1000) and relative growth rate (0.0090 g g day&lt;sup&gt;-1&lt;/sup&gt;) were obtained from mulch covered plants grown in Kolibri varieties during September 1&lt;sup&gt;st&lt;/sup&gt;. As a result, in this study higher dry matter accumulation was achieved by 1&lt;sup&gt;st&lt;/sup&gt; September seed sowing times in vegetable growing in the last season in the greenhouse. In this way, the plants have successfully grown up and increased their productivity by entering the winter months, when the temperature and light intensity are decreasing.&lt;/p&gt;}, number={2}, journal={Asian Journal of Agriculture and Food Sciences}, author={Özer, Harun and Özbakır Özer, Mehtap and Balkaya, Ahmet}, year={2017}, month={Apr.} }
