Response of weeds and rice yield to Italian ryegrass as a cover crop and planting density in organic farming

Abstract: Organic farming has been receiving increased attention in the agriculture sector; however, Japanese organic farming often requires intensive labor, and the yield is lower compared with the conventional rice (Oryza sativa L.) system. In this study, we examined the effects of planting density (12.7 vs. 24.2 plant m−1) and cover crop (Italian ryegrass [Lolium multiflorum Lam.] vs. winter fallow) on organic rice production in central Japan. A 2‐yr experiment was conducted under organic management in a paddy field … Show more

“…Rice yield responded differently to planting density, which interacted with other cultivation factors. Rice yields were 25 and 6.8% higher when Italian ryegrass was used as the cover crop under sparse planting conditions than under dense planting conditions in 2019 and 2020, respectively [23]. The grain yield of Ouu316 and Hitomebore tended to be higher in the practice of nitrogen-free basal dressing with sparse planting density than in the conventional cultivation [24].…”
