STUDY REGARDING THE INFLUENCE OF LIMITING FACTORS UPON DYNAMICS ON SURFACES CULTIVATED WITH WINTER RAPE IN THE LAST FIVE YEARS IN THE WESTERN PLAIN. (ROMANIA) PUBLISHEDDani GROSZ, Valeriu TABARA
The effects of global warming on Romanian agriculture and also on the cultures structure like oil seed rape, represents more intensively, especially in the last five years, a real challenge that aims a new approach that is regarding the soil works system, the preparing of germinate layer for a superior management of water in the soil. With all these the cultivator of the future oil seed rape will have to be the brave farmer, opened at new solutions from biotechnologies area, tolerant hybrids at diseases, pests, with good adaptability at hydro stress conditions, tolerant hybrids at efficient herbicides that can assure a combat from the beginning development phases of concurrent weeds. Looking at the cultivated areas with winter rape in the last five years in Timiş county, we can see a lot of changed because of property’s structured changed to agricultural areas, in the first time, but to agricultural mentality about the technology of oil seed rape and to the climate changes. Taking in consideration the climatic factors on which the farmer must ply in such a manner to reduce the risks of a failure in oil seed rape culture, must be adopted a system of works for soil with a minimum number of passes, a right away preparing of the soil where the preceding plant is wheat, in such a manner to close the soil capillarity to maintain the water in soil, humidity that with a minimum of precipitations registered after sowing to assure an explosive and uniform east of the culture. Although the oil seed rape culture is very technical, risky due to the climatic conditions, it remains a culture that brings the first money, a culture with an acquisition price in grew in every year, reaching an average price of 0,79 lei/kg in 2007, at 2,2 lei/kg in 2012 and this thing assures it a continued upward trend regarding the surfaces occupied in west of Romania.
