OPTIMISING TINE WEEDING IN ORGANIC PEA CROPS

摘要

Field trials were undertaken over three years to determine the effect of tine weeding in organic pea (Pisum sativum) crops in Canterbury. The tine weeding treatments were performed either as single or repeated passes at different times of crop growth.Significant weed control and yield increase were achieved with a single pass of tine weeding either at pre-emergence or at the 2-leaf stage of the crop. On some occasions two passes of tine were required to control new weeds. Late post-emergence tine weeding did not have a positive effect on pea yield.
