Abstract:

Increased fruit consumption urges manufacturers to develop effective techniques to improve production. Moreover, a major market demand is ecological fruits, leading to the emergence of a large number of organic fertilizers. The aim of this paper is to demonstrate the superior quality of the ASFAC BCO-4 organic fertilizer, regarding biometric measurements of fruits, bio-indicators and phytochemical indicators. Thus, the action of this fertilizer was highlighted for three apple varieties: Jonathan, Idared and Golden Delicious. The treatment with the ASFAC BCO-4 fertilizer was applied at two important stages of the growing season: beginning of flowering phenophase and petal shedding phenophase. A first observation was a major increase of the yield for the fruits obtained after the treatment. Also, important growth increase were observed for bio-parameters. Another important result observed for all the studied varieties was the increase of chlorophyll a and b content, leading to an intensification of the photosynthesis process.

Keywords:
