Feeding effectiveness on biological manifestations in broccoli for late field production
Keywords:
broccoli; organic fertilization; poultry manure; Hemozym N-K 4, 5-6; morphological and economic signs; qualityAbstract
The study was conducted between 2011 and 2014 on two broccoli varieties: Fiesta F1 and Parthenon F1 grown using late field production technology. Three fertilizer variants were investigated: poultry manure, Hemozym N-K 4,5-6, and no fertilizer control. It was investigated that both broccoli varieties have been shown to exhibit specific reactions to fertilization with poultry manure and Hemozym NK. For Parthenon F1, the application of organic fertilizers has a positive effect on the height, diameter and weight of the central flower heads broccoli. In the Fiesta F1 variety only with Hemozym NK fertilization, the investigated signs have higher values than the control. In both genotypes, the yields of central flower heads in Hemozym NK fertilization were higher than those reported for the control variant, with the Fiesta F1 variety exceeding 6.2% and the Parthenon F1 by 13%. Fertilizing variants have been found to have a positive effect on increasing the ascorbic acid content of both broccoli varieties, with a greater effect on fertilizing poultry manure. The dry matter content increased only when fertilizing with Hemozym NK and the effect was observed for the Fiesta F1 variety.8/
