Stimulatory effects of biological fertilizers on the productivity of greenhouse vegetable crops

Abstract

Modern agriculture, although effective in increasing yields, relies heavily on the intensive use of chemical inputs, leading to progressive degradation of the environment and soil fertility. With this in mind, this study aims to assess the effect of biofertilizers derived from marine species on the growth of Solanum lycopersicum L. (tomato), a strategic crop in Algeria. The experimental work was carried out under semi-controlled conditions in a greenhouse, and involved the application of various marine extracts ،in crude or formulated form. The effects of these bioproducts were analyzed on several morphological, physiological and reproductive parameters. Results showed M and AV_F and D ،extracts significantly stimulated vegetative growth, increased dry and fresh weight of roots and aerial parts, as well as floral and fruit induction. In addition, these treatments improved the chlorophyll content and water retention of plant tissues, reflecting improved stress tolerance, and extracts AV and D and SYN stimulated vegetative growth of tomato plants. The study confirms the effectiveness of marine biofertilizers as sustainable alternatives to chemical fertilizers, boosting productivity while respecting ecological balances. These results encourage the adoption of these bio stimulants as part of a more environmentally-friendly agriculture
