Abstract
We have analysed the influence of the straw matting in the western part of Tokyo in the course of mulberry growth during the summer.
We have made experiments for lots, that is, storw matting, and no matting, in order to test the significant difference amoung them. The design of the plots and the cross-section of each plot were shown in Fig 1. The soil temperatures were observed at 9 every morning, at the soil surface, 10cm and 20cm below the surface. The soil moisture content were observed during the period between the 29 July to 7 August every 4 days at 10, at the soil surface, 20cm and 40cm below the surface.
The analysis was carried through by the methods of analysis of variance. Although the difference of the soil temerature can be seen in Fig 2, there is no significant amount of variation among the mulberry leaf yields by the use of lots,
