abstract:
Researches were conducted in the greenhouse of Institute of Soil Science and Plant Cultivation – National Research Institute in Puławy. Plants were cultivated at Mitscherlich pots which contained mixture of soil and sand in amounts of 5 and 2 kg per pot, respectively. The first row factor were two genotypes of pea: Rola – leafy type, and Piast – afila type, and the second factor was type of water used for plant watering: non-magnetized water (control) and magnetic conditioned water. For conditioning of water the fish-plate and flowing devices of ”Maksor” firm were used, with magnetic induction of 0.2 and 1.0 T, respectively. The intensity of water flow was 1 l/min. The aim of under-taken studies was the evaluation of magnetic conditioned water influence on seed germination and growth, development and yielding of pea. It was found that magnetic conditioned water increased pea germination. It concerned time as well as the dynamics of plant emergence. Plants watered with mag-netic conditioned water achieved greater absolute growth rate (GR) and relative growth rate (RGR) than plants watered with normal water. Use of magnetic water caused significant seed yield increase of both pea varieties. Yield increase was a consequence of greater number of pods per plant and greater number of seeds per plant, since the thousand seeds mass did not change. In the available literature there are no univocal solutions concerning the effects obtained as a result of magnetic conditioning of water. However, divergence of obtained results can result from different values of used magnetic field parameters and intensity of water flow during its treatment.
