soil types on aspects of dry matter production. Sugar cane variety used in the experiments was NCo 310 (Succharum officinarum L.). Planting density was 40cm\u00d7135cm for standard block, and 20cm\u00d7135cm for dense planting block both in intrarow spacing and row width; and the soil type was marl soil and coral limestone soil. Results obtained are as follows : In this study dense planting did not affect the cane yield. For example, the final cane yield and brix for standard block and dense planting block both in marl soil field were 8.1 tons per 10 a and 17 degreee, 7.6 tons per 10 a and 16.7 degree, respectively. On the other hand, those for dense planting block in coral limestone soil were 6.2 tons per 10 a and 16.7 degree. In the experiments in marl soil, total dry weight including dead part and dry stalk weight both per unit land area kept increasing in the two planting density blocks until the last experiment day in February. In the coral limestone soil, however, the total dry weight was decreasing in the dense planting block during December and February, while dry stalk weight kept a constnt value in the same block and during the same period. The number of stalks per unit land area in December was larger in dense planting block by 2.5 to 3.6 per one m^2 than in standard block, but there was not much difference at harvest time and in the first part of growth stage (Table 1). Crop growth rate (CGR) of standard block in marl soil showed the value of 17-18g/m^2/day during the summer period of June to October, and that of dense planting block in coral limestone soil was almost the same value of 17-18g/m^2/day during August and October. In other periods except to the above mentioned periods, CGR was small (Fig.3). Leaf area index (LAI) in each block did not exceed 2.5,and the effect of planting density on LAI was not found (Fig.3). CGR showed a statistically significant positive correlation to net assimilation rate (NAR) with r=0.914,but it did not to LAI. Community light extinction coefficient (K) in the last ten days of August gave large negative values as LAI increased to the range of 1.3-3.1 (Fig.7). Distribution rate of dry matter into the stalk kept high value of 60 to 80 percent throughout the experiment period of June to February (Fig.4).", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/3904"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
