Mulching and fertilization as main technological means used for an organic broccoli crop

Abstract

The purpose of the presentpaper is to evaluate the influence of mulching and fertilization on an early broccoli crop grown according to organic farming norms. The research was carried out in the experimental field of the Agronomic University of Iaşi, Romania. In the bifactorial experiment, the influence of mulching with three graduationswas tested-unmulched-Ct, mulching with polyethylene foilof 15 and 30 microns thick,as well as the fertilization with three graduations -unfertilized-Mt, organic fertilization and application of microorganisms, under the conditions of the years 2018 and 2019. The culture was established fromseedlings of42 days, in strips of 2 rows each, the distance between strips beingof80 cm and between rows of 60 cm. The distance between plants was of 25 cm,resulting in a density of about 57 thousand plants per hectare. The obtained results indicate increases inthe yield,in the case of the mulched and organicallyfertilized variants, the best yields being obtained in the case of the mulched variant with 30 microns foil and organically fertilized with Orgevit
