WATER USE AND THE CONTROL OF WATER STRESS IN HIGH DENSITY PLANTINGS
In HDP systems the relative amounts of root at depth and under the grassed alley increased, so increasing the volume of soil from which they could extract water.
Soil applied irrigation increased the growth and cropping of HDP systems even with overall herbicide management but the trees still suffered water stress. In other trials, the intermittent wetting of the leaves by sprinklers or mist application reduced water stress and increased yield and quality. This technique may be particularly useful in HDP orchards.
