THE INFLUENCE OF NUTRITION ON THE MAIN PRODUCTION OF BROCCOLI

The research was realized in the unheated greenhouse of Horting Institute Bucharest, in 2012 year. It have aimed the influence of one phase of fertilization with ammonium nitrate (NH4NO3) on inflorescences of broccoli, at a hybrid F1-Ironman. The fertilizer was used before the formation of main inflorescences, in different doses (100 kg/ha, 150 kg/ha, without fertilizer). Harvesting was done in 4 stages. A phase of fertilization with ammonium nitrate has influenced the main production of broccoli: the variant with fertilization 150 kg/ha has obtained the highest percentage of inflorescences formed, the average weight/inflorescence largest and superior production compared with other variants. Were obtained direct linear correlations between the doses of ammonium nitrate (NH4NO3) and the production aspects followed (percentage of main inflorescences harvested, average weight/inflorescence, total production), significances of the correlations very high
