Investigation of the effect of fungi on soil aggregate stability and productivity

This study was conducted in botanical garden of Gaziantep University in the 2014-2015 cultivation period in order to investigate the yield characteristics of canola plant with the effect of different winter canola (Brassica napus ssp. Oleifera L.) varieties on soil aggregate stability and macro micronutrients in Gaziantep region. As a result of the research, it was determined that canola plant species affected soil aggregate system positively, pH (7,89- 7,95), EC (0,04% -0,05%), OM ratio (1,38-%) Lime ratio (% 18,48-% 21,5), P (16,6- 30,8 ppm), K (615-1016 ppm), Cu (1,88-2,1 ppm) ), Mn (13,18-15,98 ppm), Ca (5547- 6466 ppm) and Mg (319-482 ppm), Statistically positive significant correlations were found between OM-P, OM-K, K-EC, K-P, Mn- Fe and Mg-K, Substantial negative correlation between Cu-OM, Cu-P, Cu-K and Mg-Cu were depicted. From the yield parameters of canola plant, plant height (105- 173 cm), number of branches (1- 25 pieces), number of capsules (31- 923), number of seeds in the capsule (144- 311 pieces) and seed weight (1000 pieces) (1, 43- 6,15 g), Statistically positive significant correlations were found between number of capsules and number of branches and plant height and seed weight.
