Field and laboratory studies determined the effect of intercrop plants (rye, buckwheat, white mustard and sunflower) used in carrot cultivation on the occurrence of Clonostachys spp., Albifimbria spp., Trichoderma spp. and Penicillium spp. in the soil and their antagonistic activity. Rye and white mustard were the most effective in limiting the occurrence of soil-borne fungi. Those plants caused an increase of the population of the studied antagonistic fungi. Buckwheat and sunflower promoted the development of antagonists a little worse. The antagonistic activity of the aforementioned fungi was the highest after using rye and white mustard and slightly after buckwheat and sunflower. Those fungi were the most effective in inhibiting the growth of Altenaria dauci, A. radicina and Sclerotinia sclerotiorum pathogenic towards carrot.

The studies determined the effect of bacteria Bacillus spp. and Pseudomonas spp. isolated from the soil after carrot cultivation on pathogenic fungi Altenaria dauci, A. radicina, Fusarium oxysporum, F. solani, Rhizoctonia solani and Sclerotinia sclerotiorum. A field experiment on carrot cultivation considered different intercrop plants (rye, buckwheat, white mustard, sunflower). Rye and buckwheat were the most conducive to the growth of Bacillus spp. and Pseudomonas spp. Those bacteria were the most effective in inhibiting the growth of F. solani, F. oxysporum and R. solani. The antagonistic effect of soil-borne Bacillus spp. and Pseudomonas spp. towards the tested fungi was the largest after the application of rye and white mustard as intercrop plants in the cultivation of carrot. Buckwheat and sunflower showed a slightly smaller influence on the antagonistic activity of the studied bacteria. Bacillus ssp. had a significantly lesser antagonistic effect than Pseudomonas ssp.

The present studies aim at determining the antagonistic effect of selected fungi species occurring in the soil under carrot cultivation towards Altenaria dauci (J.G. Kühn) J.W. Groves & Skolko, Alternaria radicina Meier, Drechsler & E.D. Eddy, Fusarium oxysporum E.F. Sm & Swingle, Rhizoctonia solani J.G. Kühn and Sclerotinia sclerotiorum (Lib.) de Bary. The field experiment considered cover crops (oats, tansy phacelia and vetch). The control consisted of traditional carrot cultivation (without cover crops). Statistically, the smallest population of fungi was found in 1 g of soil dry weight after the application of oats, and a slightly bigger – after tansy phacelia and vetch. The largest population of fungi was obtained in the traditional cultivation of carrot. Cover crops contributed to the increase of the population of antagonistic Clonostachys spp., Myrothecium spp., Penicillium spp. and Trichoderma spp. in the soil. Regardless of the experimental treatment, those antagonistic fungi were the most effective in limiting the growth of S. sclerotiorum, A. dauci and A. radicina. The effect of those fungi was a little smaller towards F. oxysporum and R. solani. Oats as a cover crop had the best effect on the antagonistic activity of the studied fungi occurring in the soil environment of carrot.

The principles of good agricultural and horticultural practice, which considers both environmental protection and high yielding of plants, require modern methods of cultivation. Cover crops are used in the cultivation of various plants, including root vegetables such as carrot. The purpose of field and laboratory studies was to determine the effect of selected cover crops on the healthiness of carrot (Daucus carota L.). The field experiment took into consideration cover crops such as spring rye, white mustard, buckwheat, fodder sunflower and two systems of soil tillage, i.e.: tillage before winter (ploughing) + spring tillage (a combined cultivator) and only spring tillage (a combined cultivator). In each experimental treatment, the number and healthiness of carrot seedlings were determined. A laboratory mycological analysis made it possible to determine the qualitative and quantitative composition of fungi infecting the underground parts of carrot. Good emergencies and the healthiness of carrot plants were observed in the objects with rye and white mustard as cover crops. The cultivation system had no significant effect on the proportion of diseased seedlings of carrot. Rye and white mustard were more effective than buckwheat and sunflower in limiting  the occurrence of fungi pathogenic towards carrot. Diseased seedlings and roots after harvest of carrot were most frequently colonized by Altenaria alternata, A. chartarum, A. dauci, A. radicina, Sclerotinia sclerotiorum, Rhizoctonia solani and Fusarium spp.

Cover crops are used in the cultivation of various plants. They properly modify the composition of soil microorganisms and can protect of plants from phytopathogens. The purpose of the field and laboratory studies was to determine the quantitative and qualitative composition of microorganisms in the soil under carrot cultivated with the use of oats, tansy phacelia and spring vetch as cover crops. The paper presents also studies on soil-borne fungi threatening the healthiness of carrot roots. In the conventional cultivation of carrot the population of bacteria (including Pseudomonas spp. and Bacillus spp.) was the smallest, while after the application of oats it was the largest. Oats and spring vetch were most effective in limiting the occurrence of soil-borne fungi. Those plants and tansy phacelia caused an increase of the population of saprotrophic fungi (Albifimbria spp., Clonostachys spp. and Trichoderma spp.) in the soil. Intercrop plants had a positive effect on the healthiness of carrot seedlings and roots. Alternaria dauci, A. alternata, A. radicina, Fusarium oxysporum, Globisporangium irregulare, Neocosmospora solani, Phytophthora sp., Rhizoctonia solani and Sclerotinia sclerotiorum proved to be the most harmful towards the studied underground parts of carrot. Oats proved to be the most effective in inhibiting the occurrence of the pathogenic fungi for Daucus carota L.

An extensive survey of fungi associated with post-harvest carrot degradation in different parts of the Baghdad market. samples were collected from three different regions of Adhamiya, Kadhimiya and Sadiyah . Five fungal species, such as , Aspergillus nige, Altinaria radicina, Sclerotinia sclerotorum, Geotrichum candidum and Rhizoctonia carotae, which isolated from the decayed samples. In this context, Altinaria radicina showed the highest frequency of 23.3%. Both Sclerotinia sclerotiorum, Aspergillus nige, Geotrichum candidum at 20% While Rhizoctonia carotae showed the lower frequency at 16.7%. Pathogenic exam showed that all isolated fungi were pathogenic to host roots Storage. However, Aspergillus nige was found to be more pathogenic to carrots resulting in a rapid disintegration of infected roots by 90%during the incubation period. While Alternaria radicina, Sclerotinia sclerotiorum, was 80% followed by Geotrichum candidum 75% and Rhizoctonia carotae less than 70% .

The behavior of people who less consume vegetables and fruit can have a negative impact on health. The lack of appetite for vegetable consumption by the society made the researchers interested in making a combination of vegetables, namely carrots with local foods, namely Baroncong.This research aims to determine the acceptability of local baroncong snacks with the addition of carrots.This research is a pre-experimental study. The panelists from this study consisted of 30 Nutrition Department Students from Health Polytechnic Ministry of Health Makassar. Assessment based on taste aspects, color of aroma and texture of baroncong products with the addition of carrots 50%, 75%, 100% with the criteria of very like, like, dislike and very dislike.The results showed that the acceptability of baroncong with the addition of carrots in terms of taste was a concentration of 75%, which was very much as much as 46.7% and liked as much as 50%, the color aspect was 50% concentration consisting of 36.7% likes and likes as much as 53.3%, the aroma aspectis a concentration of 50% which consists of very much as much as 33.3% and likes as much as 63.3%, in terms of aspects of texture are concentrations of 50% and 75%, each of which consists of as much as 23.3% and likes as much as 63, 3%. Based on these data, Baroncong with the addition of carrots received is a concentration of 75%.
