“…In the following year, the plants that received N, regardless of the dose (100 or 200 kg ha -1 of N) differed from the zero dose, presenting the highest levels of leaf N. And agreeing with the results obtained by Dolinski et al (2005), and Brunetto et al (2007). However, the levels were below normal, as established by the RS / SC (2016) Soil Chemistry and Fertility Commission, reinforcing the hypothesis that there may have been an underdosing of N. The K levels were not affected, unlike the observed by Sete et al (2015), which verified a quadratic increase of K with the increase of the dose of organic compound produced from waste from juice industries, poultry slaughtering and sawdust. This increase of K may have occurred due to the fact that the nutrient is found in part in the free form in the residue, different from the present work in which the K was not supplied to the plants.…”

O trabalho foi conduzido na área experimental pertencente à Embrapa Clima Temperado, Pelotas-RS, entre os anos de 2012 e 2014. Os tratamentos foram compostos por três genótipos (‘BRS Kampai’, ‘BRS Rubimel’ e ‘Seleção Cascata 805’) e três doses de adubação nitrogenada de manutenção (0, 100 e 200Kg N ha-1), avaliados num delineamento experimental em parcelas subdivididas. Teve como objetivo avaliar o efeito da adubação nitrogenada de manutenção sobre desenvolvimento vegetativo e produtivo de pessegueiros cultivados em alta densidade de plantio. Nas condições de avaliação do experimento foi possível concluir que as doses de nitrogênio testadas não influenciam no número de frutos por planta e nem na massa médio dos frutos. No entanto estas influenciam diretamente na massa de ramos retirados durante a poda verde.

“…Similar results were obtained by Guarçoni & Ventura (2011), who reported that the increase of the N amount led to an increase of leaf length. According to Medeiros et al (2004), the addition of N promotes cell division, and it is involved in growth and development (Oliveira et al, 2015).…”

The objective of this work was to evaluate the effect of nitrogen fertilization on the mineral composition of leaves, initial growth, and yield of peach (Prunus persica) tree advanced selections grown at a high-planting density. The experiment was carried out between 2012 and 2015 in a randomized complete block design, with a combination of advanced selections of the 'Cascata 1513' and 'Cascata 1067' peach trees and of N fertilization doses (0, 30, 60, and 120 kg ha-1 N). Green weight after pruning, diameter, and increase of trunk diameter, canopy volume, plant height, branch length, number of buds per centimeter of shoot, chlorophyll index, leaf area, rust incidence, average production, number of fruit, and mass of fruit were evaluated. Genotype affects the vegetative growth and productive performance of peach trees. The application of N to dense peach orchards promotes a greater vegetative growth of the plants and increases the content of the nutrient in leaves. The initial production is affected by N fertilization. The recommendation of N fertilization made to date is insufficient for peach trees at high-density management systems of production.

O N quando absorvido em quantidades acima da demanda da planta pode estimular o vigor da parte aérea, diminuindo a incidência de raios solares no interior do dossel, a circulação de ar e, consequentemente, potencializar a ocorrência de doenças fúngicas nas folhas e também reduzir a taxa de fecundação das flores (Duchêne et al, 2001).…”

Organic waste Mineral nutrition Plastic sheetinRESUMO: A aplicação de composto orgânico nas linhas e entrelinhas de videiras pode aumentar a disponibilidade de nutrientes no solo, afetando o estado nutricional das plantas, a produção e a composição das uvas. O trabalho objetivou avaliar o estado nutricional, a produção e a composição das uvas de 'Niágara Rosada' (Vitis labrusca L.) sob cobertura plástica e submetidas à aplicação de composto orgânico na linha e na entrelinha de plantio. O experimento foi conduzido em um vinhedo da cultivar Niágara Rosada sob cobertura plástica nas linhas de plantio em um Neossolo Litólico, em Bento Gonçalves (RS), Brasil. Em agosto de 2008 e 2009 foram aplicadas cinco doses crescentes de composto orgânico (0, 9, 18, 36 e 72 L/planta ano -1 ) na linha e entrelinha de plantio das videiras. Na safra de 2008/2009 foi avaliado o número de cachos por videira e a produção de uva, e na safra de 2009/2010 foi mensurada a concentração de nutrientes nas folhas, os componentes de produção e as características químicas da uva. A aplicação de doses de composto orgânico na linha ou entrelinha de plantio de videiras 'Niágara Rosada' cultivadas em um Neossolo Litólico pouco afeta o estado nutricional das plantas, a produção e a composição da uva. ABSTRACT:The application of organic compost in rows and between rows of vines can modify the availability of nutrients in the soil, affecting nutritional status, yield and characteristics of the grape. The experiment was carried out in 2008/10 to evaluate the leaf nutrient content, yield and grape composition of 'Niagara Rosada' vines grown with plastic covering in the plant rows in an Udorthent soil, in Bento Gonçalves (RS), Brazil. In August of 2008 and 2009, five doses of organic compost (0, 9, 18, 36 and 72 L plant -1 year -1 ) were applied, in the rows and between the rows of the vines. In 2008/09, the number of bunches and yield were evaluated. In 2009/2010, leaves were collected, oven-dried, and weighed, and nutrient content was analyzed. In addition, yield components, grape yield and grape composition (pH, total soluble solids, total acidity, tartaric and malic acids) were evaluated. The application of doses of organic compost in the row and between the plant rows of 'Niagara Rosada' vines has little effect on the nutritional state, yield and must composition.
