Abstract

The main goal of the present study was to establish the influence of different rate of fertilization with nitrogen, phosphorus and potassium and interaction with the environmental conditions and their effect on phenological development of the carrot seed plant. The experiment was carried out in the Experimental fields of the Agricultural University of Plovdiv, Bulgaria with carrot variety Tushon. The plants were grown by conventional technology with steckling. Two way of fertilization was applied. In the first one, the total amounts of fertilizers were put in the autumn soil treatment and in the second one, it was split twice - in autumn the half and the other in spring in stecklings planting. The phenophases of beginning and mass: developed of leave rosette; appearing, flowering, developed and maturity of the seed of central, primary, secondary and tertiary umbels were recorded. Morphological characteristic of seed plant as a high and total vegetative weight was established. The average daily temperature, maximal and minimal temperature, rainfall and the hydrothermal coefficient of vegetation period were calculated. The relations between phenological behaviors and morphological development and elements of climatic conditions were determinated. The significance of the environmental conditions on the phenological development, especially for appearing of the umbels and flowering as well as the maturity of the seeds was established.

Keywords: Seed, Phenophases, Climate conditions, Development, Temperature
