Abstract
Pot experiments were carried out for exploration responsiveness to application of five Humic acid (HA) concentration rates (0,500,1000,1500 and 2000 ppm) and with irrigation by magnetized water (MW), solely or combined for controlling Meloidogyne javanica infected khella plants (Ammi visnaga L.) in relation to its morphological characters; yield parameters and medicinal components through two winter seasons (2012 and 2013) under shield conditions. Generally, all treatments reduced significantly number of root galls; egg-masses; soil, root population density of the M. javanica and increased tested plant morphological characters i.e., plant height; number of main branches; fresh weight of whole plant and yield parameters such as, number of umbels; its fresh and dry weights (g/plant), and fruit yield (g/plant ).Dual application of both HA and irrigation with MW combined gave better results more than the solely one in controlling of M. javanica and all plant characteristics during the tested two winter seasons. Combined treatment of (HA 1500 ppm + MW) gave the highest reduction percentages in M. javanica population (71.0 and 71.8%) through the two successive seasons, respectively. In addition, application of the same combined treatment gave a best results of gall index (1.5 and 1.5); egg-masses production (7.0 and 8.0), in the both seasons, respectively, and a better enhancement in Khella morphological characters and its yield parameters. Highest value of khellin % explicitly was obtained by using 1000 ppm HA+MW and 1500 ppm HA +MW during the two successive winter seasons, respectively.
