Filipov, S., Agricultural University, Plovdiv (Bulgaria)
An investigation on the influence of the rates and frequency of nitrogen fertilization over the vegetative and generative features of field pepper was conducted. The experiment was carried out on the field of the department of Horticulture at the Agricultural University in Plovdiv. The experiment was made with the Kurtovska kapiya pepper cultivar as a midearly field prtoduction, planted at the end of May and the beginnin g of June. The soil profile was a raised flat bed and the applied planting scheme was 110+50/20 cm with one drip tape. A positive relation was found between the nitrogen feeding frequency through fertilization during vegetation and the height and mass of the stems.The variants with threefold and fourfold nitrogen incorporation surpassed the control by 5% - 62% depending on the phase and the rate of fertilization. A similar trend was observed in teh number and mass of the leaves. The variants with the greatest economocally-significant early ripening were those with threefold and fourfold feeding, surpassing the control by 2% to 20%.
