Influence of conditioned water on germination and initial of growth selected crop species

Exact laboratory experience was conducted in year 2006. It consisted of a series of tests aimed to determine the effect exerted by water subject to magnetic treatment on germination and growth of examined plants. The following plants were tested: Coriander Coriandrum sativum,, Salvia Salvia officinalis, Bean Phaseolus vulgaris, Cucumber Cucumis dativus. All experiment stages were car-ried out in germination apparatuses, which were provided with bases consisting of two layers of impurity-free absorbent paper. Individual plants were examined according to the following pattern: three repetitions 50 seeds each for the test object and for an object, where water treated with magnetic field was used. Mag-netizer consisting of several sections was used to obtain the effect of water “magnetization”. One section consists of an axially magnetized ring-shaped magnet made of barium ferrite and ring-shaped steel pole. After having pene-trated the pole, magnetic fluxes generated by magnets change their direction from axial to radial [www.crylomag.com.pl]. Magnetizer version used in the experiment is a model without flange with the following parameters: working pressure 0.6 MPa, average water flow 2.25 m3•h-1, induction value 0.30 T. The effect of mag-netic water treatment has been achieved by letting the medium pass through the ...

Vegetables are considered to be plants with high water requirements. A greater susceptibility to water deficit occurs in the periods of intensive growth and yield formation. At that time even a slight reduction in water supply can deteriorate yielding, thus those periods are referred to as critical periods in terms of water supply. The aim of this paper has been to analyse the pattern of precipitation deficits for the ground cultivation of cucumber, tomato, beans and peas in the Bydgoszcz region in the thirty-year period 1981-2010. The basic of analysis were results of standard meteorological measurements from the Research Station of the Faculty of Agriculture and Biotechnology 'Mochełek', University of Technology and Life Sciences. Values of optimal precipitation for medium soils were calculated according to Klatt. Atmospheric precipitation deficits in subsequent month of selected vegetables cultivation were calculated by diminish between the real and optimal precipitation. The trends of deficiency of precipitation in the examined period were estimated too. Very frequent occurrence of the atmospheric precipitation deficits during the entire cultivation period of selected vegetables, and especially in critical periods was demonstrated. Slight decreasing tendency of precipitation deficits in a vegetation periods was indicated, however in a critical periods in terms of water supply, the trend line remains at a practically constant level. The results obtained indicate the necessity of the irrigation in the cultivation of peas, beans, cucumbers and tomatoes.
