This study examined the result of 1'3 year application sequences of two brassica green manures (Indianmustard cv Nemfix and BQ mulchTM), Nemfix seed meal and NemacurÂ® on the suppression of root knotnematode Meloidogyne javanica in soil and roots, and the consequent improvement on vigour and productivityof Vitis vinifera cv Semillon. Soil examination revealed ca. 37'78% suppression of M. javanicapopulations when soil was amended with brassica green manures, Nemfix seed meal and NemacurÂ® for1'3 consecutive years compared to unamended soil. In all cases, M. javanica populations were significantlyreduced after 1 year of treatment with a further reduction in the second year of treatment. Thethird year application did not have any significant reduction over the second year treatment. A suppressionof M. javanica populations in soil after 3 consecutive years of application of brassica green manures,Nemfix seed meal and NemacurÂ® significantly increased yield by 69'101% compared to the inoculatedcontrol (unamended) treatment. Three consecutive years of application of green manures and Nemfixseed meal significantly increased starch concentration in the roots to between 23 and 25% compared tothe inoculated control treatment (concentration 14%). Fresh pruning weights were significantly increasedby 35% in 2'3 consecutive years of application of Nemfix green manure treatment only compared to theinoculated control treatment. Applications of the green manures, Nemfix seed meal and NemacurÂ® for1'3 consecutive years did not have any significant effect on berry juice characteristics.
