“…This is because vines tend to use only small amounts of N derived from mineral fertilizer, according to information from Brunetto et al (2006) in a 15 N study. According to these authors, a higher amount of N accumulated in young vines was due to different forms of 15 N provided earlier at vine transplanting.…”

ABSTRACT:Viticulture is an activity of great social and economic importance in the lower-middle region of the São Francisco River valley in northeastern Brazil. In this region, the fertility of soils under vineyards is generally poor. To assess the effects of organic and nitrogen fertilization on chemical properties and nitrate concentrations in an Argissolo Vermelho-Amarelo (Typic Plinthustalf), a field experiment was carried out in Petrolina, Pernambuco, on Syrah grapevines. Treatments consisted of two rates of organic fertilizer (0 and 30 m 3 ha -1) and five N rates (0, 10, 20, 40, and 80 kg ha), in a randomized block design arranged in split plots, with five replications. The organic fertilizer levels represented the main plots and the N levels, the subplots. The source of N was urea and the source of organic fertilizer was goat manure. Irrigation was applied through a drip system and N by fertigation. At the end of the third growing season, soil chemical properties were determined and nitrate concentration in the soil solution (extracted by porous cups) was determined. Organic fertilization increased organic matter, pH, EC, P, K, Ca, Mg, Mn, sum of bases, base saturation, and CEC, but decreased exchangeable Cu concentration in the soil by complexation of Cu in the organic matter. Organic fertilization raised the nitrate concentration in the 0.20-0.40 m soil layer, making it leachable. Nitrate concentration in the soil increased as N rates increased, up to more than 300 mg kg -1 in soil and nearly 800 mg L -1 in the soil solution, becoming prone to leaching losses.

“…Entretanto, sua recuperação e acumulação são pequenas (Brunetto, 2004;Brunetto et al, 2006b) e, por isso, pode ser necessária a complementação de N via aplicação foliar (Tagliavini & Toselli, 2005 (Fregoni, 1980), o que facilita a absorção do N aplicado. A aplicação foliar de N é uma prática comum durante o período vegetativo e produtivo da videira.…”

RESUMO -No Rio Grande do Sul (RS), as aplicações foliares de nitrogênio, quando necessárias, têm sido usadas para complementar a adubação via solo. Entretanto, carece-se de informações dos efeitos da freqüência e da quantidade de N aplicado sobre a sua dinâmica na folha e de reservas nitrogenadas e de carboidratos nas partes perenes da videira, que compõem o objetivo deste trabalho. O trabalho foi conduzido em um vinhedo da cultivar Chenin Blanc, safra 2004/05, na Embrapa Uva e Vinho, em Bento Gonçalves (RS), sobre um Neossolo Litólico. Os tratamentos consistiram de uma, duas e três aplicações foliares de 0 (água); 1,11; 2,23; 3,31 e 4,41g de N planta -1 . Após cada aplicação de nitrogênio, foram coletadas folhas inteiras (limbo+pecíolo) no terço médio dos ramos do ano, no interior e exterior dos diferentes lados da planta, secas, moídas e preparadas para a análise de N total. Na última época de coleta de folhas, foram coletados três ramos do ano em cada planta, retiradas seis gemas em cada ramo, as quais foram submetidas à análise de amido, carboidratos solúveis totais, carboidratos redutores, aminoácidos totais e proteínas totais. As aplicações foliares de N aumentaram o teor do nutriente na folha inteira, de forma destacada, nas épocas de coletas próximas às aplicações; entretanto, essas aplicações diminuíram os teores de amido e carboidratos solúveis totais nas gemas dos ramos do ano e não afetaram os teores de carboidratos redutores e os totais de aminoácidos e proteínas. Termos de Indexação: Vitis vinifera, adubação foliar, amido, aminoácidos, proteínas. NITROGEN FOLIAR SPRAYING IN GRAPEVINE: CONTENT IN LEAVES AND RESERVE OF NITROGEN AND CARBOIHYDRATES IN SHOOTS BUDSABSTRACT -Leaf nitrogen application is used in grapevines in Southern Brazil as complement to soil fertilization. On the other hand, there is no information about its affects on nitrogen content in the leaves and nitrogen and carbohydrates reserves in the perennial parts. The experiment was carried out in 2004/2005, with the objective to evaluate the effect of nitrogen foliar spraying on leaves and nitrogen and carbohydrates reserves in shoots buds of Chenin Blanc grapevine, at Udorthent soil, in Bento Gonçalves, Rio Grande do Sul, Brazil. The treatment was three foliar applications: 0 (water); 1.11; 2.23; 3.31; 4.41g N grapevine -1 . Leaves were picked, dried and prepared to total nitrogen analyses. In the last leaf sampling, three shoots and six buds were taken in each plant, prepared and analyzed for starch, total soluble carbohydrates, carbohydrates reducers, total amino acids and total proteins. Leaf nitrogen application increased nitrogen content in the leaf and decreased starch content and total soluble carbohydrates in shoots buds, but did not affect carbohydrates reducers and totals of aminoacids and proteins. Index terms: Vitis Vinifera, foliar fertilization, starch, aminoacids, proteins.

“…These percentages varied according to rootstock and amount of mineral fertilizer applied on the soil, in a five year trial. On the other hand, Brunetto et al (2006), in an experiment with 'Chardonnay' grapevines in field conditions, verified low rates of N utilization ranging from 5.78 to 3.42%, derived from annual ryegrass and white clover covers, respectively. Brunetto et al (2014) using also the 15 N isotopes labeling method, reported that The N derived from the rye litter added to the soil surface (82 kg N ha -1 ) was mostly accumulated in the annual and perennial organs of the 'Niagara Rosada' grape at a similar percentage most of the N contained in 51 'Niagara Rosada' grape organs was derived from different N sources rather than rye litter.…”

SUMMARYGreen manures have become an important option for recycling nutrients in organic cropping. However, its benefits are often not obtained in the short term. In this context, the study aimed to determine whether the use of cover crops during winter can contribute to N provision in the following spring, in the beginning of the growth of young grapevines. The winter green manure species white lupin (Lupinus albus), forage pea (Pisum arvense), common vetch (Vicia sativa), hairy vetch (Vicia villosa), triticale (Triticale hexaploide), oat (Avena sativa), ryegrass (Lollium multiflorum) and forage turnip (Brassica rapa) were grown until flowering in 4 L pots and fertilized with ammonium sulfate enriched at 10% with 15 N atoms. In the following spring, grapevines cv. Niagara Rosada (Vitis labrusca) grafted on two different rootstocks (IAC-572 'Jales' and IAC 766 'Campinas') were planted in 14 L pots where it was superficially applied one of the five different sources of N. The green manure species employed as N source were forage pea (Pisum arvense), common vetch (Vicia sativa), hairy vetch (Vicia villosa) and oat (Avena sativa). The soil surface was covered with the dry matter from the green manure species (3g dry matter pot -1 ) or fertilized with ammonium sulfate enriched at 2% with 15 N atoms. The results demonstrated that the oat plants showed the highest dry matter content (11.68 g pot -1 ). The species forage pea, hairy vetch and common vetch had the lowest C/N ratios, with values of 16, 16 and 18, respectively. Hairy vetch was the most efficient (255.1 mg pot -1 ) for the accumulation of N and oat plants showed the highest N uptake from the mineral fertilizer. The N uptake and accumulation by the 'Niagara Rosada' grapevines varied according to N source and rootstock. Grapevines accumulated N in higher amounts from mineral fertilizer, followed by the N from leguminous species and then lower quantities from the oat plants. Grapevines grafted on the IAC-572 'Jales' rootstock accumulated higher amounts of N than those grafted on IAC-766 'Campinas', probably due its higher vigor and, consequently, better soil exploration by the roots. Despite of the rootstock, between the green manure species, the N from forage peas was the most recovered by the grapevines cv. Niagara Rosada, attaining 30.8%, while common vetch 23.1%, hairy vetch 19.0%, and oat only 5.2%. RESUMOOs adubos verdes constituem uma importante opção na reciclagem de nutrientes em sistemas de produção orgânicos. No entanto, os seus benefícios normalmente não são obtidos num curto prazo. Neste contexto, este estudo teve como objetivo determinar se o uso de culturas de cobertura durante o inverno pode contribuir para o fornecimento de azoto na primavera seguinte, no início do desenvolvimento de videiras jovens. As espécies tremoço branco (Lupinus albus), ervilha forrageira (Pisum arvense), ervilhaca comum (Vicia sativa), ervilhaca peluda (Vicia villosa), triticale (Triticale hexaploide), aveia (Avena sativa), azevém (Lollium multiflorum) e nabo forrageiro...
