“…Faber et al (2001) found that root system growth in the superficial soil layers can be favored by the presence of mulching, facilitating the absorption of nutrients such as phosphorus, which is accumulated in the superficial layers due to its low mobility. In addition , Bremer Neto et al (2008) stated that the balance between mineralization and immobilization of soil N could be affected by mulching distribution in order to reduce its availability to plants and require complementary fertilization of this nutrient.…”

Irrigation has been pointed out in recent decades as the major consumer of water. Considering the need for a rational use of water resources and the importance of mulching for planting, this study evaluated the effect of organic mulching (sugarcane straw) under soil water storage for cabbage crop development. This research was conducted at CCA/UFSCar, and the experimental design was a completely randomized design with four replications and two treatments with and without sugarcane straw. Water application was performed by a drip irrigation system and irrigation management was determined from data collected by TDR. The use of organic mulching did not interfere with cabbage productivity under greenhouse conditions. The straw presents efficiency for reduction of soil evaporation and, consequently, increases water-use efficiency. The soil cover made it possible to save up to 28.1 mm (14.5%) of the water depth.

“…No caso do consórcio com fruteiras as leguminosas herbáceas perenes se mostram bastante promissoras (Bremer Neto et al, 2008) pelo fato de serem mantidas como coberturas vivas por meio de roçadas periódicas, após semeio, dispensando nova compra de sementes ou mudas em ciclos posteriores da cultura principal. Para a bananeira resultados de pesquisas têm demonstrado boa eficiência das plantas de cobertura no que diz respeito ao fornecimento do N (Espíndola et al, 2006b;Perin et al, 2009) mas muito ainda se precisa saber sobremaneira no que diz respeito à escolha das melhores plantas de cobertura e do manejo desse sistema sob irrigação em regiões semiáridas.…”

RESUMOCom este trabalho objetivou-se avaliar o crescimento, a nutrição e a produção da bananeira Prata Anã (Musa spp), consorciada com leguminosas e submetida a diferentes lâminas de irrigação. O delineamento experimental utilizado foi em blocos casualizados em parcelas subdivididas, com cinco repetições. As parcelas foram formadas por quatro lâminas de irrigação: 50, 75, 100 e 125% da evapotranspiração da cultura (ETc) e as subparcelas pela testemunha (manejo convencional sem plantas de cobertura) e três tipos de plantas de cobertura consorciadas com a bananeira, são elas: vegetação espontânea (VE), cudzu tropical em sucessão à crotalária (CK) e calopogônio em sucessão ao feijão-de-porco (FC). Avaliaram-se, nas plantas de bananeira, a altura, a circunferência do pseudocaule, os teores foliares de macro e micronutrientes, a produção e a duração do ciclo. A utilização de leguminosas no pré-plantio e como cobertura viva, exerceu influências positivas no crescimento, na nutrição nitrogenada e na produção da bananeira, substituindo parcialmente o N aplicado como fertilizante mineral. O uso de leguminosas consorciadas com a bananeira representa uma alternativa adequada para o fornecimento de N à cultura da bananeira. Palavras-chave: manejo da irrigação, adubação verde, Musa spp.Growth, nutrition and yield of banana associated with cover crops and irrigation depths ABSTRACT The objective of this study was to evaluate the growth, nutrition and production of Prata Anã banana (Musa spp), intercropped with legumes and subjected to different irrigation depths. The experimental design was a randomized block split plot with five replications. The plots were formed by four irrigation depths: 50, 75, 100 and 125% of crop evapotranspiration (ETc) and the control subplots (conventional management without cover crops) and three types of cover crops intercropped with banana: spontaneous vegetation (VE), tropical cudzu in succession to crotalaria (CK) and calopogônio in succession to jack beans (FC). In banana crop, the height, pseudostem circumference, foliar concentrations of macro and micronutrients, production and crop cycle duration were evaluated. The use of legumes in the pre-planting and as a cover crop exerted positive influences on growth, nitrogen nutrition and yield of banana, partially replacing the N applied as mineral fertilizer. The use of legumes intercropped with banana represents an adequate alternative to provide N for banana.

“…Alternatively, there is the possibility of producing grass biomass between the rows of orange orchards with mechanical mowing for mulch accumulation on the soil in plant rows (Beraldo et al 2007;Bremer Neto et al, 2008;Fidalski et al, 2009). However, the effect of mulching in the plant rows has not been evaluated for the possible responses of rootstocks, which may differ in soil water uptake and consumption.…”

SUMMARYThe increased availability of soil water is important for the management of non-irrigated orange orchards. The objective of this study was to evaluate the availability of soil water in a Haplorthox (Rhodic Ferralsol) under different tillage systems used for orchard plantation, mulch management and rootstocks in a "Pêra" orange orchard in northwest Paraná, Brazil. An experiment in a split-split-plot design was established in 2002, in an area cultivated with Brachiaria brizantha grass in which three tillage systems (no tillage, conventional tillage and strip-tillage) were used for orchard plantation. This grass was mowed twice a year between the rows, representing two mulch managements in the split plots (no mulching and mulching in the plant rows). The split-split-plots were represented by two rootstocks ("Rangpur" lime and "Cleopatra" mandarin). The soil water content in the plant rows was evaluated in the 0-20 cm layer in 2007 and at 0-20 and 20-40 cm in 2008-2009. The effect of soil tillage systems prior to implantation of orange orchards on soil water availability was less pronounced than mulching and the rootstocks. The soil water availability was lower when "Pêra" orange trees were grafted on "Cleopatra" mandarin than on "Rangpur" lime rootstocks. Mulching had a positive influence on soil water availability in the sandy surface layer (0-20 cm) and sandy clay loam subsurface (20-40 cm) of the soil in the spring. The production of B. brizantha between the rows and residue disposal in the plant rows as mulch increased water availability to the "Pêra" orange trees.Index terms: Brachiaria brizantha, no tillage, soil management, soil texture, time domain reflectometry.(
