Abstract
The experience was brought out to the experimental fi eld of the Agroecological Centre at the Agricultural University of Plovdiv which owns a Certifi cate of ecological farm work. The research was carried out on two pepper cultivars: Gorogled 6 and Buketen 50 – intended for production of red pepper for grinding. For the purpose of the experiment a bio-fertilizer, produced by the Californian earthworm Lumbricus rubellus was used. Two levels of the bio-fertilizer were applied - 50 and 100 ml/per plant. It was determined that the bio-fertilizer speeds up plant growth. It infl uences the growth rate of the roots and stems and affects the formation of the foliage. The bio-fertilizer has a positive effect upon the functional activity of the photosynthetic apparatus /increased content of photosynthetic pigments, improved leaf gas exchange/. The biofertilizer also infl uences the yield (raw material for drying). The highest effect has been achieved at application of 100 ml fertilizer to the Gorogled 6 cultivar.
