“…This is particularly significant given the various health benefits associated with both nutrients. Additionally, the positive correlation between moisture content and fat aligns with previous findings 36 and suggests an interesting interplay between these two attributes. On the contrary, the negative correlation between moisture content and carbohydrates underscores the importance of moisture management, as higher moisture content can compromise root quality and promote the activity of rot-causing pathogens.…”

The increasing global concern about ecologically unsafe agricultural practices calls for an investigation of how fertilizer combinations and harvest age interact to influence the biochemical qualities of crops. The study objective was to determine the biochemical responses of three carrot varieties to fertilizer composition, and harvest-age interactions. Three carrot varieties, Graffas, Carrot Touchon, and Nantes; four fertilizer compositions, 10 t/ha of poultry manure + 200 kg of NPK 15:15:15 (PM10 + NPK200), 20 t/ha of pig manure + 200 kg of NPK 15:15:15 (PIG20 + NPK200), 350 kg of NPK 15:15:15 (NPK350), and 0 t/ha (control); and three harvest-age, 10, 12, and 14 weeks after planting (WAP) were evaluated in a 3 x 4 x 3 factorial in randomized complete block design with 3 replications. Variations in biochemical concentrations of carrot roots with variety, fertilizer type, and harvest-age interactions were recorded. Proximate qualities were generally higher in Nantes and Graffas varieties grown with the combined use of organic and inorganic fertilizers harvested at 10 WAP. Phytochemical quality was higher in Graffas and Carrot Touchon grown with PM10 + NPK200 when harvested at 14 WAP. Nantes variety grown with NPK350 and harvested at 12 WAP had higher vitamin contents. Root weight had a positive correlation with saponin (0.22), carbohydrate (0.31), alkaloid (0.33), vitamin E (0.26), and fiber (0.19). Vitamin C displayed positive correlations with vitamin B (0.43), vitamin E (0.56), alkaloid (0.67), tannin (0.31), saponin (0.32), and carbohydrate (0.35), while beta-carotene exhibited positive correlations with vitamin A (0.42) and tannin (0.38).

Background Recommendations for fertilizer use in agriculture do not take into account the growing region and the source of the organic matter. In addition, vegetable growers are unaware of the quantities of fertilizer to be applied during cultivation. Accordingly, there are increasing complaints about the poor quality of the vegetables produced which is likely associated to the type and the dose of fertilizer used. Therefore, the objective of this work was to determine the probable origin of poor carrot quality in production basins in Cameroon. The factors consisted of five carrot genotypes and nine fertilizer types arranged in the field in a split-split plot experimental design. The sensory quality of the carrot samples was assessed by a quantitative descriptive test. The nutritional value was determined according to the treatments performed. Results The results of this study showed that both the sensory quality and nutritional value of carrots significantly depend on the variety, and the type and dose of fertilizer used. However, the variety New Kuroda treated with 10 t ha−1 of chicken manure and the unfertilized variety Vanessa F1 were recorded as having the best sweetness and overall acceptability scores. The best nutrient parameters such as total carbohydrate, proteins, ash, cellulose, NDF and ADF were obtained with the carrot varieties New Kuroda grown with a combination of chemical fertilizer (300 kg ha−1) + chicken manure (10 t ha−1), Pamela + unfertilized, Madona fertilized with 10 t ha−1 chicken manure, with 600 kg ha−1 chemical fertilizer + 5 t ha−1 chicken manure or not fertilized, Amazonia fertilized with 300 kg ha−1 chemical fertilizer and Vanessa F1 fertilized with a combination of 600 kg ha−1 chemical fertilizer + 5 t ha−1 of chicken manure. Conclusion Carrots with good sensory quality such as sweetness and deep orange colour were obtained with unfertilized Vanessa F1 variety. The variety Amazonia fertilized with 300 kg ha−1 chemical fertilizer provided good nutritional parameters including carotenoids, fibres, carbohydrates proteins and lipids.

In rational nutrition, vegetables play an important role due to their high biological and low energy value. The most widespread vegetables in our country belong to root vegetables. They are grown mainly for bulbs, corms, rhizomes, fleshy roots, and hypocotyl tubers. Root vegetables can be eaten raw or cooked. Carrot (Daucus carota L.) is a basic representative of root vegetables. For the most valuable components counts beta-carotene – the major component of total carotenoids. This paper evaluates changes in total carotenoids, refractometric dry matter, and gravimetric dry matter in three varieties of carrot (Kamaran F1, Komarno F1, Romosa) grown in soil and climatic conditions ex-situ in Nitra. We have evaluated roots grown in non-fertilized soil, soil after application of manure, horticultural compost, and their combinations. The results show that the variants fertilized with compost and a mixture of compost and manure had the most considerable influence on the synthesis and content of total carotenoids as well as the content of dry matter and refractometric dry matter
