Root Vegetable Crops

The glucosinolate profile of leaves and seeds of 33 Brassica napus L. crops, including leafy crops, forage, rutabaga, and oilseed crops, was compared by high-performance liquid chromatography to investigate the relation between the consumable product of each crop and the glucosinolate profile. Glucosinolate concentration was higher in seeds than in leaves, varying from 3.8-fold in oilseed crops to 7.1-fold in root vegetable crops. Aliphatic glucosinolates predominated in both organs. In seeds, aliphatic glucosinolates represented between 91% to 94% in the different groups, whereas in leaves there was more variation. For root vegetable crops, aliphatic glucosinolates represented 80% of the total glucosinolate concentration. For leafy and forage types, aliphatic glucosinolates represented approximately 90% and for oilseed crops represented 92%. Indole glucosinolates were more abundant in leaves (5% to 17%) than in seeds (5% to 8%). The total glucosinolate content in leaves ranged from 14 to 24 μmol·g−1 dry weight (DW) in oilseed and forage types, respectively, whereas in the seeds, it ranged from 55 to 115 μmol·g−1 DW in oilseed and forage types, respectively. Significant differences were noted among the four groups in glucosinolate concentration and glucosinolate composition. In the seeds, progoitrin was found as the main glucosinolate in all groups. In the leaves, two different glucosinolate profiles were found depending on the crop: forage and root vegetable crops showed high levels of progoitrin, whereas glucobrassicanapin was the main glucosinolate for oilseed and leafy crops. We suggest that different selection criteria applied on B. napus crops according to their use could have led to an indirect selection for glucosinolate profile in leaves.

Root Vegetables

The production, value and quality of root vegetables are endangered by numerous phytopathogenic fungi and pests. Numerous causal agents cause economically significant diseases of root vegetables like carrot leaf blight and black rot of carrots (Alternaria dauci and Alternaria radicina), powdery mildew of carrot and sugar beet (Erysiphe heraclei and Erysiphe betae), Cercospora leaf spot of carrot (Cercospora carotae), black blight (Septoria apiicola), leaf bright parsley (Septo-ria petroselini), downy mildew (Peronospora farinosa f.sp. betae and P. farinosa f.sp. spinaciae), rust (Puccinia spp.) etc. Nine fungicides based on nine different active substances have been registered in the Republic of Serbia for the control of phytopathogenic fungi in root vegetable crops. The most important pests of root vegetables are wireworms (Elateridae), carrot flies (Psila rosae), celery flies (Acidia heraclei), onion flies (Delia antiqua), aphids (Aphididae), common spider mite (Tetranychus urticass), cabbage moth (Mamestra brassicae), cotton bollworm (Helicoverpa armigera) and others. The overall number of insecticides, registered in our country, for the control of root vegetable pests is eight, based on seven different active substances. The aim of this paper is to present registered plant protection products for the control of the most economically import-ant pathogens and pests of root vegetables, in the Republic of Serbia, classified according to the mode of action.

Introduction: greenhouses need microclimate control systems to grow agricultural crops. The method of carbon dioxide injection, which is currently used by agricultural companies, causes particular problems. Co-generation power plants may boost the greenhouse efficiency, as they are capable of producing electric energy, heat and cold, as well as carbon dioxide designated for greenhouse plants.Methods: the co-authors provide their estimates of the future gas/electricity rates growth in the short term; they have made a breakdown of the costs of greenhouse products, and they have also compiled the diagrams describing electricity consumption in case of traditional and non-traditional patterns of power supply; they also provide a power distribution pattern typical for greenhouse businesses, as well as the structure and the principle of operation of a co-generation unit used by a greenhouse facility.Results and discussion: the co-authors highlight the strengths of co-generation units used by greenhouse facilities. They have also identified the biological features of carbon dioxide generation and consumption, and they have listed the consequences of using carbon dioxide to enrich vegetable crops.Conclusion: the co-authors have formulated the expediency of using co-generation power plants as part of power generation facilities that serve greenhouses.
