    Abstract: [Problem] The present invention seeks to provide a composition for plants that is highly safe and that contributes to early harvesting, increasing yield, and increasing added value of crops. Specifically, the present invention provides a yeast extract that, by addition to a foliar surface spray or to soil or water, provides an effect of promoting growth, an effect of root lengthening, an effect of improved taste, and an effect of increased amino acid content of a plant. A substance obtained from yeast that is edible and considered to be safe is preferred as the yeast extract. [Means for Solving the Problem] A yeast extract having a peptide content of 5 wt % or more and an RNA content of 5 wt % or more is sprayed onto or provided as fertilizer to a plant. The yeast extract is preferably derived from Candida utilis, which is edible and considered to be safe.

  • Publication number: 20170268198
    Abstract: A distance obtaining unit obtains the distance between a work implement and a design terrain. A work aspect determining unit determines a work aspect by the work implement. A limit velocity deciding unit limits the velocity of the work implement when the distance between the work implement and the design terrain becomes smaller. When the work aspect is surface compaction work and the distance between the work implement and the design terrain is within a first range of at least a portion that is equal to or less than a predetermined first distance, the limit velocity deciding unit increases the limit velocity of the work implement in comparison to when the work aspect is an aspect of a work other than surface compaction, or cancels the limiting of the velocity of the work implement.
