Impact of preceding cropping and cutting height on stand uniformity of corn

摘要

No-tillage ( NT ) cropping is a promising technique providing potential economic and environmental advantages compared with conventional tillage systems.In Japan, this system has been introduced into the Hokkaido and Tohoku regions (single cropping districts of summer corn) and the Kyushu region (double cropping districts of spring corn and autumn corn), but not into the central areas of the main island (double cropping districts of summer corn and winter crops).The purpose of this study was to evaluate the feasibility of NT cropping in the double cropping system composed of summer corn and winter crops.We attempted to plant corn directly following a winter crop after the first harvest by use of a no‐till planter available in Japan.We examined the relationship between the seedling accuracy of the NT planter and the residue of the preceding winter crops.
