“…Em termos de produção relativa por volume de copa, a produção observada equivale a 2,71 e 2,18 kg m -³ de copa nos pomares 1 e 2, respectivamente. Valores de 1,91 a 3,51kg m -³ de copa foram observados por Azevedo et al (2012), em plantas de mais de 16 anos de vários cultivares em Mogi Mirim/SP, e de 1,9 a 3,7kg m -³ na região de Londrina, PR (GIAMPANI et al, 2016). Muitos daqueles valores de volume de copa e de produção da 'Pêra' foram superiores ao observado em Santa Catarina.…”

Resumo-O cultivar de laranjeira 'Pêra' (Citrus sinensis (L.) Osb.) é o mais importante no Brasil, devido à sua boa adaptação no sudeste do país e à qualidade do seu suco. Porém, como é suscetível à tristeza dos citros, doença que é mais severa em climas frios-como o subtropical, que ocorre no sul do Brasil-, seu cultivo nessa região é limitado. O objetivo deste trabalho foi avaliar a potencialidade da laranjeira 'Pêra Bianchi' para o cultivo em Santa Catarina. Foram avaliados dois pomares adultos de 'Pêra Bianchi' localizados no oeste do estado. Durante duas safras, avaliaram-se o tamanho das plantas, a produção de frutos e a qualidade dos frutos (tamanho e características do suco). A laranjeira 'Pêra Bianchi' apresentou produtividade satisfatória, média equivalente a 42 e 45 t ha-1 , e qualidade de suco adequada aos padrões de mercado. Porém, grande parte dos frutos produzidos não apresentou tamanho adequado à comercialização como fruta de mesa. Foi observada considerável variabilidade entre plantas no mesmo pomar quanto à produtividade e tamanho dos frutos. Termos para indexação: Citrus sinensis (L.) Osb.; tamanho de frutos; tristeza dos citros.

“…However, the effects of green fertilization are known to be highly variable, depending on the species used, bio-mass management, planting and cutting period of the green fertilizer, duration of the residues in the soil, and local conditions, and the interactions between these factors (Fontanetti and Santos, 2010). The beneficial effect of green fertilization has already been identified in the cultivation of sunflowers, mint, 'Pera' oranges, and onions (Wendt et al, 2005;Singh et al, 2010;Azevedo et al, 2012;Souza et al, 2013).…”

Soil management in integrated rose production system

et al. 2019

Integrated production systems have been used with various crops, and their use in floriculture is innovative. The effects of green fertilization in floriculture and the appropriate fertilization levels are still unknown. The aim was to identify the best dose of chemical fertilizer, with or without green fertilization, for integrated production of ‘Carola’ roses. The treatments consisted of 4 doses of the chemical fertilization recommended for rose bushes, (25%, 50%, 75%, and 100%), with or without green fertilization (calopo). Plants that were not treated with 100% (or complete) of chemical fertilization were supplemented monthly with Bokashi (16 g/plant, via the soil) and biofertilizer (5% via the leaves). The assessments were conducted 3 times per week for a year. The use of less chemical fertilizer did not affect rose production or quality, whereas the use of green fertilization did not provide a satisfactory outcome. The analyses, biometric, accumulation and nutrient content, and chemical characteristics of the soil, indicated that green fertilization with calopo was not beneficial. Moreover, with the exception of nitrogen and magnesium, there is the possibility of using 75% of the recommended chemical fertilization in rose bushes.

“…The production of biomass of covering plants in the interrows of citrus groves and the launch of it for citrus row planting was the target of a few short-term studies with citrus fruit (a few harvests), focusing on specific evaluations of different species of cover crop, water storage capacity and control of weeds (Bremer Neto et al, 2008;Fidalski et al, 2009;Azevedo et al, 2012;Martinelli et al, 2017). However, the no-tillage and mulching effects on the rows of citrus over a long period of time were not evaluated in these studies, not even the possible responses to new rootstocks, such as the dwarfing varieties, which may differ in the consumption and absorption of water in the soil.…”

The management of soil cover plants (intercropping) in orchards can contribute to increase productivity of citrus trees. Thus, the present research aimed to evaluate different planting systems for Tahiti acid lime grafted onto Flying Dragon trifoliate orange, a dwarfing rootstock, at high planting density (1,157 trees ha −1). The study was set up in four tillage systems, using Urochloa ruziziensis as an intercrop species in the orchard, and conducted for 5 years: no-tillage (NT), no-tillage and no-herbicide (NT-NH), minimum tillage (MT) and conventional tillage (CT; without intercropping). Dry matter (DM) production of biomass in the row and interrow of the orchard was evaluated yearly, as well as weed density, soil physical and chemical characteristics, plant water and nutritional status, and fruit yield of trees. Greater deposition of DM of biomass was observed in the row of citrus planting for treatments NT and NT-NH compared to CT and MT treatments, which led to reduced undesirable weed populations. The NT treatment also provided increases of 79% in potassium (K) nutrient concentrations in the leaves of trees and 60% in exchangeable K in the soil surface layer, in the first 2 years evaluated. The maintenance of the Urochloa ruziziensis mulch in the NT system also provided higher soil volumetric moisture content and consequently lower soil resistance penetration and water stress on trees, evidenced by the predawn plant leaf water potential (<1 MPa). Moreover, the NT treatment provided an average increase of 56% of fruit yield from trees compared to the CT treatment during three harvests. This long-term study demonstrated the contribution of the no-tillage system using a favorable cover crop to increase the yield of Tahiti acid lime fruits and maintain the soil quality most required for the sustainability of citrus production.
