The Effect of Different Sowing Dates to Leaf Area Index in Some Common Vetch Varieties

Abstract

The aim of this article was to research the effect of different sowing dates on the leaf area index (LAI) of common vetch varieties growing in arid conditions. The experiment was conducted during 2014 - 2015 growing season in Igdir with arid climate. In study, Bakır-2001, Dicle, Emir, Gülhan-2005 and Nilüfer varieties were sown six different dates (E1:1 October 2014, E2: 16 October 2014, E3: 31 October 2014, E4: 15 March 2015, E5: 1 April 2015 and E6: 16 April 2015), and their LAI were measured by the tool of CI-202 at the stage of full seed filling of lower pods on plant. Results showed that the LAI differed significantly in terms of variety, sowing date and variety x sowing date interaction. Among varieties, the highest LAI was determined in Dicle and Nilüfer, but the lowest values in Emir and Bakır-2001. In reasearch, while maximum LAI was obtained from E1 time (6.22), minimum vales were measured at E6 (0.87). In respect of variety x sowing date interaction, the highest LAI was determined in Nilüfer and Dicle grown in early fall season (E1), but the lowest value in all varieties growing in summer sowing (E6). According to these results, significant decreases were seen in LAI by delay of sowing dates depending on environmental conditions, and Dicle and Nilüfer were determined as least affected varieties by low rainfall and high temperature in terms of LAI.
