Evaluation of hail damage simulation on the yield and some yield components in potato tuber the Agria cultivar in Ardabil
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 23
Abstract
In order to determine the tuber yield reduction due to hail damage simulation through aerial organs destruction of plants at different stages the Agria potato growth, an experiment was performed in Ardabil area in 2010. The test was conducted as factorial based on randomized complete block design in four replications with two factors. The first factor included six destruction levels of plant aerial organs (0, 20, 40, 60, 80 and 100 percent) and the second factor consisted of five stages of plant growth (14, 35, 49, 77 and 105 days after emergence). Results of traits variance analysis showed that there were significant differences between the levels of destruction percent and time of plants aerial organs in terms the traits such as, plant height, number of main stems per plant, number of tubers per plant, tuber weight per plant, the average of tuber size in plant, dry matter percentage, yield of salable tuber and total tuber yield and also, there were significant differences between their interaction in terms of plant height, number of main stems per plant and number of tubers per plant. Mean comparison of traits showed the most reduction was related to traits such plant height, number of tubers per plant, tuber weight per plant, the average of tuber size in plant, dry matter percentage, yield of salable and total tuber yield, time of plant aerial destruction per plants 49 and 77 days after emergence in the levels 60, 80 and 100 percent.
