The inflence of drip irrigation and agrogel on quality of rootstock Pumiselect® and one -year – old trees of two peach cultivars

key words: Pumiselect, peach tree, hard-cutting, maiden trees, drip irrigation, agrogel, quality

Summary:

The experiment was carried out in 2006-2008 years in the nurseries, in the Experimental Station belonging to Wrocław University of Environmental and Life Sciences. The aim of present study was to determine the influence of drip ir-rigation and agrogel on the growth of Pumiselect® rootstock in the first year of production and on the quality of maiden trees of ‘Redhaven' and ‘Inka' cvs. peach trees. The drip irrigation was used as a T-tape line with drip emitter lo-cated at every 25 cm in line, about water dose 1,38 l per hour. Irrigation was applied on the base of tensiometer indications. The wet agrogel placed inside a belt of fabric (wide 10 cm), was put on the bottom of furrow (at depth 35 cm) , where the plants were planted. Pumiselect® rootstock as the hard-cuttings were planted at spacing 2 x 0,25 m at the depth 35 cm. The budding was done at the beginning of August by ''chip-budding'' method at 5 cm above the soil. During the experiment: the high, diameter and branching of rootstock and maiden trees was measured. The quality of root system of rootstock was determined too.
The preliminary results shown the positive influence of the agrogel on the quality of Pumiselect® , propagated by hard-cuttings, as well as on the quality of planting material of two peach cultivars. The drip irrigation caused more inten-sive production of thick roots on the rootstock in the first year of production. The drip irrigation improved the quality of maiden peach trees in 2008 year.
