Use of Cover Crops in Organic Sweetpotato Production to Improve Yield: A Case Report

Abstract

Additionally, it has been shown that cereal rye residue releases phytotoxic compounds responsible for its allelopathic effects [18]; namely 2,4-dihydroxy-(2H)-1,4-benzoxazin-3(4H)one (DIBOA) and its breakdown product, benzoxazolin-2(3H)-one (BOA) [19]. Rapeseed (Brassica napus I.) on the other hand, as a Brassica species, contains glucosinolates, which are not phytotoxic in themselves, but as the plant tissues break down in soil, glucosinolates are
