Abstract
Growth room studies were conducted to determine the impact of Brassicaceae seed meals on the emergence of tomato and pepper seedlings in Pythium ultimum infested soils. Pasteurised Burch sandy loam soils were amended with intact and denatured seed meal of rape seed and mustard. Brassica juncea or Brassica napus intact seed meal increased the tomato and pepper seedling emergence. Interestingly, B. napus amended soils resulted in the same seedling emergence with B. juncea regardless of their relatively lower glucosinolate content compared to mustard-based seed meals. Seedling emergence in soils amended with intact Sinapis alba seed meal was significantly the lowest for both tomato and pepper seedlings. In contrast, seedling emergence was higher in soils amended with denatured than intact S. alba seed meals suggesting some glucosinolate-related inhibitory effect on seedling emergence of both crops. Glycine max seed meal amendment improved the seedling emergence better than the control but to a lower-level when compared to glucosinolate containing seed meals. This finding suggests that even though improvement of seedling emergence of tomato and pepper in P. ultimum infested soils can be achieved using Brassicaceae seed meals, it cannot be entirely attributed to glucosinolate-related processes. These studies demonstrate that intact B. napus and B. juncea seed meals can be used to improve tomato and pepper seedling emergence in P. ultimum infested soils.
