The experiment revealed the influence of both soil conditions and sowing date on growth and development of evening primrose plants. More uniform plant emergence and more intensive growth and development during vegetation were observed on silty soil. Plants were taller, more branched, formed more seed capsules, and, in consequence, yields were over two times higher. Besides, there were characterized...
A pot experiment carried out in a greenhouse in 1999-2000 was aimed at finding the effect of a constant magnetic field on the root system and green tops, as well as on yield of spring wheat. In all cases there was observed a slight stimulating effect of the factors examined. The growth dynamics were weakened. The plants were shorter, and so were their culms and ears. Moreover, the effect of a magnetic...
Demographic processes due to fast growth of the global population and urbanization are the main reason for increasing demands for food and feed. Due to urbanization processes about 50% of food is exported into towns.
