The Effect of Charcoal Rot Disease (Macrophomina phaseolina), Irrigation and Sowing Date on Oil and Protein Content of Some Sesame Lines

Öz

This study was conducted to determine the effect of charcoal rot disease (Macrophomina phaseolina) on oil and protein content of some sesame lines cultivated under different conditions at the experimental area of Dicle University Faculty of Agriculture, in 2006 and 2007. In this study, 6 sesame lines (B–60, C–7, C–36, C–53, Y–7 and Y–11) which are of Mediterranean and Southeastern Anatolia Region origin and 3 isolates which belong to the M. phaseolina fungus are treated. Before sowing, experimental area was inoculated artificially by disease factor. Sesame seeds were sown on 05 May 2006, 22 June 2006, 11 May 2007 and 22 June 2007, respectively. The experiment was established in a split-split plot design with three replications. At crop maturity, unhealthy and healthy plants on each plot were harvested separately, and adequate amount of seed samples were taken. In both years, the seeds from each plot were taken after harvest for determining oil and protein content. Average protein and oil content were recorded as 23.18% and 45.48%, respectively. Protein and oil contents were affected by sowing date, irrigation and disease. According to the obtained data, protein content of seeds obtained from unhealthy plants was found lower when compared to the healthy plants, and oil content was found higher. The highest protein content obtained from early sowing, dry conditions and healthy plants (25.99%), and the lowest content from late sowing, irrigated and unhealthy plants (20.64%). The highest oil content obtained from early sowing, irrigated and unhealthy plants (46.54%) and the lowest oil content from early sowing, irrigated and healthy plant (44.70%)
