This study examined the optimal planting density of peanut in the Tokachi region by comparing the growth and yield of the early variety ‘Tachimasari’ grown at the experimental field of Obihiro University in 2021 and 2022 at the planting densities of 5.8 plants m–2 (5.8-plot), 8.7 plants m–2 (8.7-plot), and 11.6 plants m–2 (11.6-plot). Plants in the 5.8-plot grew larger and produced more fertile pods than those in the 8.7-plot and 11.6-plot. On the other hand, pod fertility was higher in the 8.7-plot and 11.6-plot than in the 5.8-plot, and the plants in the 5.8-plot produced many immature pods. Seed yield in the 8.7-plot and 11.6-plot was 254 g m–2 and 264 g m–2, respectively, which was significantly higher than the yield of 168 g m–2 in the 5.8-plot. By growing peanut at a higher planting density than 5.8 plants m–2, decline of the pod production by each plant could be compensated by the number of plants, resulting in a higher seed yield. Stands in the 11.6-plot appeared to overgrow and exhibited a higher leaf area index than those in the 8.7-plot. This resulted in an increase the incidence of diseases conspicuously in the 11.6-plot. It was concluded that 8.7 plants m–2 was the optimal planting density for the peanut variety ‘Tachimasari’ in the Tokachi region.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本作物学会","subitem_publisher_language":"ja"},{"subitem_publisher":"Crop Science Society of Japan","subitem_publisher_language":"en"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1626/jcs.93.122","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2024, Crop Science Society of Japan.
