Morphogenetic potential of seed and explants culturing of three capsicum annuum L. ( pepper) genotypes (Gedion, Moaz, and Mohand) were studied to evaluate different plant regeneration protocols and develop a reliable system for plant propagation. An efficient procedure of in vitro plant regeneration through seed and direct shoot bud induction was tested from different explants of capsicum annuum L. Several methods of media preparation with combinations of growth regulators were used, and 2 combinations were found ideal for seed propagation with 7 mg/l 2,4-D or 5 mg/l IBA respectively. Additionally, it was indicated that seed dormancy can effect its propagation also the positioning of the seed or explants onto the media. Propagated seeds demonstrated shoot and root elongation. Regeneration of the explants did not show satisfactory results because most of the explants did not develop into normal shoots but instead developed into calli after 15 days of culture. HPLC Analysis of cultivars demonstrated that fructose suger percentage was higher in the three different types of pepper, followed by sucrose then glucose. Also the HPLC analysis drew out that media supplemented with 7mg/l 2,4-D generally had the highest effect of capsaicinoid sugar content in the following order i.e. cultivar Mohand was showed high significant in sugar content of capsaicinoid followed by Gedion and Moaz. Application of DPPH method illustrated that extracts obtained from Moaz leaves characterized the most proactive antioxidant (vitamin C) properties than Gedion and Mohand. A were noticed. The results of these studies indicated that antioxidant activities of the extract prepared from pepper leaves depended mainly on phenolic compounds.

Organic agriculture is a holistic production management system which promotes and enhances agro-ecosystem
health optimizing biological cycles and soil biological activity. Such optimization often relies on so called biofertilizers which could improve the soil nutrient management. With aim to study the effect of such group of biofertilizers on productivity and quality of economically-importanbt crop such as pepper (Capsicum annuum L.) variety Kurtovska Kapiya 1619, an experiment was carried out in 2009-2011 on the experimental fields of the Agroecological Centre at the Agricultural University-Plovdiv (Bulgaria). Solid biofertilizers, i.e. Boneprot and Lumbrical, and a liquid biofertilizer Baikal EM were tested. The content of the total digestible N, K2O and humus at the end of the vegetation showed the highest values after application of Boneprot in an optimum concentration. The highest standard yield was measured after Baikal EM on basic fertilization with Lumbrical, i.e. 15980 kg.ha-1 in 2009. The result was confirmed in 2011, i.e. 16540 kg.ha-1. The increase in comparison with the control
variants was by 61.8% and 43.8 % respectively. Upon the combined application of Baikal EM on basic fertilization
with Lumbrical, there was an increase of the number of fruits in 2010, i.e. 8.7 pcs/plant that was confirmed in 2011, i.e. 7.9 pcs/plant. The highest mass of the fruits was shown after Baikal EM on basic fertilization with Boneprot (in 2010 and 2011). The maximum value of the pericarp thickness was detected for the fruits of the variant treated with Baikal EM on basic fertilization with Boneprot. The combined application of biofertilizers showed a higher stimulative impact than the single application of biofertilizers. The higher total sugars and Vitamin C content in the pepper fruits after treatment with Baikal EM on basic fertilization with Lumbrical, determined this combination as favourable.
