It was aimed to study the improvement of growth, yield and nutrient uptake of millet and soil chemical properties by liming. Calcium carbonate was applied to the soil at 4 levels, viz. A (0g), B (7.5g), C (15.0g) and D (22.5g/pot), of which treatments raised the soil pH to 4.4,5.1,6.4,and 6.8,respectively. In the control treatment, no plant survied indicating that the millet can not tolerate strong acidity. The highest grain yield, weight of aerial parts and roots were obtained from the C treatment followed by the B treatment. Consequently soil pH about 6 was deemed to be best for the millet. The plant analysis showed that N, P and K accumulated higher at the grand growth stage before heading than the mature stage. Ca and Mg concentrations increased in the plant up to the mature stage. Increase or decrease in Si concentration of the plant varied by the treatment. Before heading, N and Si concentrations of the plant were highest on the C treatment but others were highest on the D treatment. About the quantity of nutrients taken up in the aerial portion of the millet, N was not different among the treatments, Si was highest in the B, K and Mg were in the C, and P and Ca were in the D treatment. The analysis of the soil after growing millet showed that enrichment of Ca by liming but exhaustion of N, Mg, and K by the cropping. Also indicated were remain of fertilized P, and increase in CEC by liming and cropping.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3731"}]},"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":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
