 note = {長岡市川口武道窪の32圃場の水稲について、玄米タンパク質含有率と葉色の推移および土壌肥沃度との関係を調査した。タンパク質含有率は5.3％から7.8％の変異を示し、土壌中のアンモニア態窒素含量と有意な正の相関を示した。また、葉色（SPAD値）とも正の相関を示し、とくに出穂10日後がｒ＝0.920と高かった。タンパク質含有率の年次相関が高かったので、出穂10日後のSPAD 値33で圃場を仕分け、タンパク質含有率の高低に基づく分別収穫が提案された。, Relationships among protein content of brown rice grains, the change of leaf color and soil fertility were investigatedin 32 paddy fields of Budokubo, Nagaoka City. Protein content varied from 5.3 ％ to 7.8 ％ , and positively correlated withthe nitrogen content of the soil of 32 fields. Protein content also showed significant correlations with leaf color (SPAD value)from booting stage to harvest, especially high(r=0.920) with those of 10 days after heading. Since yearly correlation of proteincontent was significantly high, it was recommended that the fields with low and high protein content should be separatelyharvested using the border leaf color, SPAD value of 33, 10 days after heading.},
