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 physico-chemical quality of the potable water, provided by the waterworksof the selected poviat from Lesser Poland voivodeship, was evaluated.The evaluation included the period of 2003-2006. The objects of the research were20 waterworks' and they were tested for the following water quality indexes: turbidity,reaction, conductivity, ammonia, nitrites, nitrates and fluorine. The resultsfrom the water quality examination, performed by the Sanitary and EpidemiologicalStation, were also used for the analysis. In order to find the variability of eachindex, apart from their average values, also the maximum and minimum amountswere counted, as well as standard deviation and the amount of transgressions ofthe admissible value of the index. The research showed high variability of the indexes'values between different waterworks during the analyzed period. Thesedifferences are clearly seen when comparing the waterworks which use thegroundwater and the waterworks which use the surface water. These first waterworksprovide water of better quality. The physico-chemical properties of watertaken from the tested waterworks are 64,3% consistent with the Ministry of HealthRegulation on the potable water quality. The majority of problems in the group ofphysico-chemical indexes is caused by the transgressions of the water turbidity indexes.In case of the groundwater intakes, the admissible value - 1 NTU was exceededby 19,2% ...
