Abstract
Rate of growth of fruit on pear trees growing on heavy soil decreased as the av. moisture content in the upper 3 ft. of soil was reduced below 70% of the available capacity. With soil moisture at 20-35% of the available capacity, rate of growth waa reduced 40%. This condition is believed to be due to the slow capillary movement of moisture and the relative sparseness of roots in the heavy soil.
