Influence of soil parameters on plant characteristics in organic farming systems

Abstract

The objective of research was to determine influence to grain yield, the quality of organic wheat Munk grain and parameters of soil by usage of growing Stimulator Penergetic-p) in organic farming. Experimental trials were implemented at the Centre of Agroecology, Lithuanian University of Agriculture during period of 2005 and 2006. Scheme of usage of Penergetic-p was as follows: I- control, II-seeds felted with Penergetic-p before sowing (a rate of 100 ml t(-1)) and III-felted with Penergetic-p) before sowing (a rate of' 100 ml t(-1)) and in the period of bushing sprayed (rate of 100 ml ha(-1)). A strong correlation (R-2=0.99) has been found between usage of Penergetic-p and yield. A significant increase in fall number of grain has been determined after the usage of Penergetic-p) in test trials II and III compared to the control trial. Other significant differences in quality indexes of grain have not been determined. According to electrochemical parameters of wheat grain, antioxidation properties of grain were found decreasing and the amount of ions of mineral materials was found increasing as a result of Penergetic-p usage.
