Effect of several tillage methods on yield and yield components of potato cv. Sante

Decrease of tillage operations causes time economy, decrease of cost, workers, energy consumption and cars traffic. Therefore, tillage implements should be selected in a way that consumes minimum energy providing suitable condition for budding and root growth. In this regard, aiming to determine the effect of different tillage methods on yield and yield components of potato cv Sante, a research has carried out done in 2013-2014 in Shahrekord country. Experiments were in the design of complete randomized block with three repetitions. Treatments included moldboard plow disk sweep cultivator leveler (as in conventional method), chisel plow twice discs, moldboard plow 뜈 cultivator, and subsoiler heavy disc. Effect of different tillage methods had significant effects on soil return, date of tuber formation, number of tuber in surface unit and performance of the product at 1%probability level. Moldboard plow had maximum numbers of tuber and performance of the product in chisel plow twice discs treatment had maximum yield. There was a significant difference among different tillage treatments in respect of micro and macro tubers percentage. Chisel plow twice discs treatment suggested in planting potato cv Sante.
