عنوان انگلیسی Niacin as a Biostimulant in Carrot Production in a Minimum Soil Tillage System in Brazil
چکیده انگلیسی مقاله The use of conservation practices and the application of biostimulants has helped to increase the production and quality of horticultural products sold in regions with periods of water restriction, such as the Brazilian Center-West. The objective of the study was to evaluate the potential use of cover species for establishing direct planting of carrots, as well as exploring the effects of applying nicotinamide as a biostimulant product for the crop. The treatments consisted of the presence or absence of niacin application and different soil cover management: control (manual weeding); straw from spontaneous plants, millet, sunn hemp and the combination of millet and sunn hemp (mix). The presence of cover crops from the cultivated species, millet and sunn hemp, alone or together, provided gains in relation to the development, productivity and quality of carrots, as well as resulting in average economic gains above 259%. Also, the application of niacin increased growth parameters, and the productivity by 82%, which increased gross revenue by around 50%. In this way, it is concluded that niacin can be used in carrot cultivation as a biostimulant aiming to increase root development and obtain greater margins of economic return, regardless of management with cover crops. However, the joint use of the vitamin and cultivated species is recommended, taking into account the possible phytosanitary implications due to the presence of spontaneous plants.
