【 摘 要 】

We cultivated a forage rice Momiroman and an ordinary paddy rice Nipponbare with poultry manure compost or chemical fertilizer. Three types of plots were prepared: standard-quantity compost (N: 2.1%, 1.8 tDM/10 a), large-quantity compost (3.6 tDM/10 a), and chemical fertilizer. We investigated the effects of compost application on high yielding ability of Momiroman: nitrogen uptake and dry matter production at the ripening period. The results showed that nitrogen uptake and dry weight were greater in Momiroman than in Nipponbare in both chemical fertilizer and compost plots. The results also showed that the ear weight increases with the increase in assimilation during the ripening period. The leaf area was large and leaf nitrogen concentration was high in Momiroman in the large-compost plot, even during the ripening period. Momiroman had longer plant length than Nipponbare, and its leaves were widely distributed from the lower to upper part of the stem: this structure reduced the loss of relative light intensity regardless of the leaf area increase and maintained good radiation interception. Consequently, although Momiroman has a smaller leaf area than Nipponbare, the dry matter production per leaf area and dry matter production are larger in Momiroman than in Nipponbare at the ripening period. From these results, we conclude that application of poultry manure compost in a large quantity increases the assimilation at the ripening period; thus compost in a large-quantity compost can increase the yield and protein of Momiroman.
