Effect of improvement of soil's physical and chemical characteristics on quality of potato
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 22
Abstract
Potato is an important global food source and one of the most important sources of starch. Interaction between physical and chemical characteristic is important source of variation in any crop including potato, so in this experiment one cultivar of potato cv Draga was studied on factorial design on the base of randomized complete block design in four replications in Ardabil, Iran. Some parameters such as percent of starch, percent of dry matter and the size of tuber were evaluated. Farmyard manure were placed in four levels 0, 15, 30, 45 ton/ha in main plots, and in second plots, there were two levels with and without subsoiling. Effect of suboiling for all measured traits was insignificant, and subsoiling with farmyard manure has no interaction for all measured traits too. Result analyses of variance of data indicate that there is significant difference between farmyard manure with percent of dry matter and percent of starch. There is no significant difference between farmyard manure with tuber size, no correlations between all of experimental qualitative factors.
