Abstract

The purpose of the research was the evaluation of organic and mineral fertilizers influence on the spring- planted rape seed plants development level in the first period of ontogeny. The plants development a then droppings (2,5 t/ha); hen droppings (2,5 t/ha) with zeolite (3 t/ha); mineral fertilizer (N60:P60:K60) separately and together with zeolite (3 t/ha); zeolite in pure form (3 t/ha) application into the soil was studied. The control was without any fertilizer application. These fertilizers led to the intensive plants growth at the first development stages, the vegetative plants weight and root system increase, the leaves surface development. In its turn this affected the photo synthetic parameters positively. The most active photosynthetic activity was marked at the plants with the application of hen droppings in pure form (2,5 t/ha) and together with zeolite (3 t/ha). All biometric parameters of rape seed plants in the plant formation preparatory stages were increased in comparison with the control. The parameters under study were at the level of the control while applying zeolite in pure form, and the combined application of zeolite with fertilizers ensured essential increase. The study of the plants trace element composition allows to determine that zeolite shows sorption ability in relation to high-density metals, as a result the plants vegetative part accumulates them in less quantity.
