UZUN, B., E. YOL and S. FURAT, 2012. The influence of row and intra-row spacing to seed yield and its components of winter sowing canola in the true Mediterranean type environment. Bulg. J. Agric. Sci., 18: 83-91 The objectives of the study were to assess the effects of row and intra-row spaces to seed yield and its components and also determine the optimum row and intra-row spacing for canola in order to obtain better yield in Mediterranean type environment conditions. The field experiment was intended factorial randomized complete blocks design with three replications in West Mediterranean Agricultural Research Institute's fields of Antalya at 2006-2007 and 2007-2008 growing seasons. Rows were spaced of 10, 20, 30, 40 cm; intra-rows were spaced of 5, 10, 15, 20 cm with a registered canola cultivar. Traits. such as seed yield, plant height, number of branches, stem height to the first pod, number of pods per plant, number of seeds per pods and 1000 seed weight were analyzed. The results indicated that row spacing had a significant effect on seed yield, number of branches, number of pods per plant, number of seeds per pods in two growing seasons. The highest seed yield was obtained in 10 cm row spacing along with 5-10 cm intra row spacing. Number of branches, number of pods per plant and number of seeds per pods were affected negatively by narrow row spaces. Narrow row spaces affected seed yield, positively and strongly. Narrow row spaces are prerequisites for obtaining higher yields in canola in Mediterranean-type environment.
