In the period 2005-2007 were carried out trials with five oats populations (Krivogastani, Trebenista, Radolista, Bugarija and Kuceviste) and three oats varieties (Rajac, Slavuj and Lovkjen), which were set in terms of organic and conventional production. The time and duration of individual stages in oats growth depends on a number of factors, among which should be mentioned: the variety, soil fertility, climatic conditions and agro techniques. Our main objective was to determine the differences in time of occurrence of certain stages because of the system of cultivation, ie, conventional farming systems or organic farming system. During vegetation, the changes in the development of reproductive organs of class are monitored. Taking into account the fact that the plants in organic farming system, in all years of the examination, in the initial stages had faster vegetative growth, in tasseling stage organic production came to the fore, especially in 2006, when all populations and species tasseled 4-5 days earlier. The method of cultivation, its influence highlighted by shortening the organogenetic development of organic production for 2-3 days in the first, second and third year of examination. |
