The experiment was installed in a greenhouse with the aimed to verify the influence of liquid swine waste in the development and nutrition of Corymbia citriodora seedlings. The swine waste was mixed with a commercial substrate in order to analyze the effects of five doses, in a randomized block design, considering the N requirement of the species, which were T1 – 0%; T2 – 50%; T3 – 100%; T4 – 150% and; T5 – 200% and one treatment with mineral fertilization for comparison. The Corymbia citriodora seeds were germinated in plastic tubes with a commercial substrate plus swine waste. As the seedlings reached about five centimeters the thinning was performed, and when the plants reached 15 cm in length the growth analysis was started. At the end of the experiment the seedlings were measured, weighed and milled for macro and micronutrients determination. The best doses of liquid swine waste were 150% and 200% which showed the highest growth average values of the Corymbia citriodora seedlings, to the detriment of the nutritional and physical improvement of the substrate.

Mineral fertilization is an important practice that contributes to the production of seedlings with satisfactory quality. This study aimed to evaluate the effect of the application of potassium chloride (KCl) and monoammonium phosphate (MAP) on growth and nutrition of Eucalyptus urophylla x Eucalyptus grandis seedlings. The experiment was conducted in full sun, with direct sowing in tubes containing composite substrate (Pinus bark, coconut fiber, bovine manure and vermiculite). The experimental design was a randomized block design in a 5 x 2 factorial scheme, with five doses of KCl (0.0, 0.025, 0.050, 0.100, and 0.200 g seedling-1) and two doses of MAP (0 and 0.10g seedling-1), with four replicates. At 120 days, the effect of the interaction between the KCl and MAP doses was verified for the variables: diameter at root collar, dry mass of the aerial part (DMAP) and total (TDM), Dickson Quality Index, N content, P K in the aerial part, K content in the roots, absorption efficiency (AE) of N and P. For the variables: height (H); leaf area; root dry mass (RDM); H/DRC and DMPA/RDM ratios; and N and P content in the roots, only effect of the application of MAP is observed, whereas for AE_K the effect was only of KCl. Thus, there is variation in the effect of KCl doses as a function of morphological and nutritional variables evaluated. In general, the best seedling growth and nutrition occurs with the applied dose of 0.100 g KCl + 0.10 g MAP seedling -1.

The study aimed to evaluate the efficiency of nutrient use in three cactus forage (CF) cultivars (Opuntia stricta and Nopalea cochenillifera), 365 days after planting under different types of fertilizer in two research sites (Condado and Riachão) of the semi-arid region of Paraiba state, Brazil. The experimental design was a randomized block design with treatments in a factorial scheme (3×4), three cultivars of CF (Orelha de elefante Mexicana; Miúda; Bahiana), and four fertilizer treatment (Control; Manure; Manure with Nitrogen; Mineral fertilization) with four replications. The CF cultivars did not differ significantly in nutrient use. That means of physiological efficiency by CF cultivars were 1.62, and 2.36 kg of biomass per kg of nutrient applied in Condado and Riachão, respectively. The efficiency of nutrient recovery was 16% for the Condado, according the following order: K> P> Ca> N> C = Mg and 12% for Riachão: K> P> N> C = Ca = Mg. In the two research sites, the treatment with mineral fertilization significantly increased the efficiency use of N, P and K in comparison to the other treatments. The average for efficiency of nutrient utilization was 25% and 19% for Condado and Riachão, respectively, in the following order for Condado: K> P> N> Ca = Mg> C, and Riachão: K> P> N> C> Mg = Ca. In a CF production system aiming to obtain a yearly harvest cycle, it is necessary to replenish of K and P to maintain the nutritional balance between the soil and CF plant.

<title>ABSTRACT</title><p>The aim of this study was to evaluate the yield and nutrition of castor bean in response to fertilization with sewage sludge and potassium (K) and magnesium (Mg) sulphate. The experiment was carried out from January to July 2011. The treatments, in a randomized block design with three replicates, in a Nitosol, corresponded to a factorial scheme (2 x 4 +1): two doses of K and Mg sulphate combined with four doses of sewage sludge (0, 2.60, 5.20 and 10.40 t ha<sup>-1</sup>, dry basis), applied based on its nitrogen (N) content and the N requirement for the crop and an additional treatment with NPK. The castor bean grain yield fertilized with sewage sludge did not differ from conventional fertilization, with the maximum value achieved at a dose of 7.5 t ha<sup>-1</sup> of sewage sludge. The fertilization with sewage sludge increased zinc and copper levels in the soil to values close to or higher than those in conventional fertilization, without any influence on the concentrations in the leaf. Fertilization with K and Mg sulphate increased the levels of these cations in the soil without affecting the concentrations in the leaves. The fertilization with sewage sludge increased the contents of organic matter, sulfur, zinc, iron, copper and boron in the soil, and manganese and boron in castor bean leaves.</p>

ABSTRACT Wheat and corn are important grains in the agricultural scenario of Brazil, and demand adequate supply of nutrients, particularly nitrogen, in crop succession. The use of pig slurry (PS) as a full and/or partial alternative to mineral fertilization in crop areas has been identified as an important alternative for the disposal of this waste. Therefore, the objective of this study was to evaluate the utilization of PS as fertilizer in wheat/corn succession under some plant parameters and grain yield. The experiment was conducted under field in randomized block design with four replications and five treatments, three with PS (40, 80, 160 m³ ha-1) and two controls (no fertilization and mineral NPK fertilization), which were applied manually in the soil shortly after sowing the crops. The application of PS proved to be a significant source of nutrients in wheat/corn succession. In comparison to NPK fertilization, this increase was only of 5.4% and 4.7% for wheat and corn, respectively. PS is an efficient alternative and it can be used as a source of these nutrients in wheat/corn succession, and the use of 80 m3ha-1 provides satisfactory results for all evaluated variables.

ABSTRACT High prices and the scarcity of hardwoods require the use of alternative wood sources, such as the Guapuruvu (Schizolobium parahybae), an arboreal species native to the Atlantic Forest, which has fast growth and high market potential. However, there is no information on its cultivation in the Brazilian Cerrado. Thus, this study aimed to analyze the contribution of mineral fertilization and liming in a Cerrado soil on the initial growth of Schizolobium parahybae. The experiment was set in a randomized block design, with 4 treatments (Cerrado soil; soil + liming; soil + fertilizer; and soil + fertilizer + liming) and 15 replicates. The following variables were analyzed: plant height, stem diameter, number of leaves, total, shoot, leaf, root and stem dry matter, and root/shoot ratio. The obtained data were subjected to the analysis of variance, Tukey test and regression analysis. During the initial growth, Schizolobium parahybae can be cultivated in a Brazilian Cerrado soil only under mineral fertilization, with no need for soil liming.

ABSTRACT The objective of this study was to evaluate the effects of the addition of parts of leguminous trees on the growth and nutrition of maize (Zea mays L.), as well as on the chemical attributes of a degraded soil, 65 days after applying the residues. The experiment was conducted in pots, in a randomized block design with ten treatments and four replicates. The evaluated treatments were: T1 - No residues of leguminous trees, T2 - Leaves of Mimosa caesalpiniifolia, T3 - Branches of Mimosa caesalpiniifolia, T4 - Leaves + branches of Mimosa caesalpiniifolia, T5 - Leaves of Mimosa hostilis, T6 - Branches of Mimosa hostilis, T7 - Leaves + branches of Mimosa hostilis, T8 - Leaves of Gliricidia sepium, T9 - Branches of Gliricidia sepium and T10 - Leaves + branches of Gliricidia sepium. Pots were filled with soil from a degraded area and residues were added in the form of green mass after sowing the maize. Residues of leguminous trees positively influenced maize growth at 65 days after application and favored the accumulation of nitrogen, phosphorus and potassium in the shoots. Green fertilizers improved soil chemical attributes at 65 days after application, especially nitrate-N (NO3 --N), ammonium-N (NH4 +-N), total inorganic N (NO3 --N + NH4 +-N) and K, demonstrating that these species are good options for recovering degraded areas in the semi-arid region of Ceará.

ABSTRACT The use of pig deep-litter (PDL) in pasture fertilization can be an important alternative from an environmental and economic point of view. This study was conducted to evaluate the fertilization with PDL exclusively or in association with mineral fertilizers on the quality and productivity of Panicum maximum cv. Mombasa. The experiment was carried out in Ipameri, GO, Brazil. The design was a randomized block design in a 2 x 5 factorial scheme with four repetitions, in plots of 24 m². The doses of PDL (0; 5; 10; 15 and 20 Mg ha-1) were tested, with or without fertilization with NPK (50 kg ha-1 of P2O5, 10 kg ha-1 of K2O and 10 kg ha-1 of N). The organic fertilizer was applied broadcast at the planting of the pasture, and the mineral fertilizers were split and applied at planting and as topdressing. Dry mass, crude protein, acid detergent fiber and neutral detergent fiber were evaluated. PDL doses associated with mineral fertilization led to linear increases from 52 to 282% in the analyzed variables and better bromatological composition. PDL application is beneficial to the production of pastures, and increasing applications up to the PDL dose of 20 Mg ha-1 associated with mineral fertilization promoted better quantitative and qualitative results. With exclusive fertilization with PDL, the gains in quality and productivity were more modest.

This study evaluated the production of Paiaguás grass (Urochloa brizantha) as a function of wood-ash doses and water availability in the Cerrado Oxisol. The experiment was carried out in a greenhouse with a randomized block design in a fractioned 5x5 factorial scheme, corresponding to five wood-ash doses (0; 8; 16; 24 and 32 g dm-3) and five soil water-availability scenarios (4; 8; 16; 32; 64 kPa) with four repetitions. The experimental design was based on the modified central compound and consisted of 13 treatments of wood-ash doses (g dm-3) and soil water-availability scenarios (kPa): 0-4; 0-16; 0-64; 8-8; 8-32; 16-4; 16-16; 16-64; 24-8; 24-32; 32-4; 32-16; 32-64. Soil volumetric moisture was monitored daily by means of the Diviner 2000 Capacitance Probe® for soil water replenishment according to the treatments. In 30-day intervals, three cuts were performed in the aerial part of the plants evaluating dry mass of leaves, stems, aerial part, number of leaves and of tillers. Data were subjected to analysis of variance and when significant to regression analysis, both up to 5% of error probability, through the statistical program SISVAR and response surface study using SAS. The combinations of wood ash doses with water soil tensions influence the productive characteristics of Paiaguás grass. Fertilization with wood ash reduces the effect of water stress on Paiaguás grass and this residue may be a viable alternative to partial replacement of mineral fertilization and safe disposal in the environment.

ABSTRACT Potassium is the nutrient required in greatest quantity by watermelon, especially during the production phase. Therefore, the aim of this experiment was to evaluate the effect of potassium and cattle manure doses on the nutritional composition of ‘Crimson Sweet’ watermelon plants. The treatments were arranged in a randomized block design with three replicates and 21 plants per plot using a 3 × 5 + 1 factorial scheme, referring to three manure doses (0; 1,100 and 2,520 g hole-1), in order to increment the level of soil organic matter from 0.67 present in the soil to 3.0 and 6.0%, five potassium doses (0, 7.5, 15, 22.5 and 30 kg ha-1) in the form of potassium chloride and one additional treatment (without organic and mineral fertilization). At the beginning of fruiting, leaves were collected to evaluate the nutritional status of the plants in macronutrients. According to the results, cattle manure stimulates the absorption of macronutrients by watermelon; in soil with 3.0% of organic matter, the best results corresponded to the K2O dose of 15 kg ha-1 and, for 6.0%, between 11 and 13 kg ha-1.

Objetivou-se determinar por meio do estudo da marcha de absorção, as quantidades acumuladas e a partição de macro e micronutrientes em meloeiro amarelo Goldex fertirrigado em comparação ao fornecimento pelo solo e pela fertilização. O experimento teve delineamento de blocos casualizados com nove tratamentos e quatro repetições. Cada bloco tinha área de 2,0 m x 27,0 m, onde foram alocadas as parcelas experimentais, contendo 20 plantas. Foram coletadas amostras de solo e plantas em intervalos de 7 dias, iniciando-se aos sete dias após o transplantio (DAT) até os 63 DAT. Em cada período foram estimados os acúmulos de macro e micronutrientes em diversas partes das plantas, assim como as respectivas quantidades fornecidas pelo solo. O acúmulo total de nutrientes pela parte aérea do meloeiro seguiu a sequência: K>Ca>N>S>P>Mg>Fe>Mn>Zn>B>Cu. Para os macronutrientes, ocorreram picos de acumulação  aos 28 DAT para N e Mg, aos 35 DAT para K e Ca e aos 49 DAT para N, P, K e Mg. Os micronutrientes tiveram picos de acumulação aos 35 DAT para Fe e Mn e aos 42 DAT para Cu e Zn. Há necessidade de melhorar a sincronia das taxas de aplicação via fertirrigação com as taxas de acumulação da cultura, para maioria dos nutrientes no meloeiro amarelo na mesorregião de Mossoró (RN). Palavras-chave: Cucumis melo L., eficiência nutricional, acumulação de nutrientes  OLIVEIRA, F.S.; OLIVEIRA,F.S.; ARAUJO, J.L.; ROCHA, R.C.; ROCHA, G.H.CPARTITION AND NUTRIENT ACCUMULATION IN YELLOW MELON UNDER FERTIGATION CONDITIONS IN SEMIARID REGION  2 ABSTRACT Optimizing the use of fertilizers depends on information about amounts of nutrients required in the different phenological phases of the crops. The objective of this work was to determine through the study of the accumulation march, the partitioning of macro and micronutrients in yellow Goldex melon (Cucumis melo L.) under fertigation in relation to the soil and fertilization supply. The experiment had a randomized block design with nine treatments and four replications. Each block consisted of an area of 2.0 m x 27.0 m where nine experimental plots containing 20 plants were allocated. Soil and plants samples were collected in seven-day intervals, starting 7 days after transplanting (DAT) up to 63 DAT. In each period, the accumulation of macro and micronutrients in different plant parts and soil supply were estimated. The total accumulation of nutrients in melon shoots followed the sequence: K>Ca>N>S>P>Mg>Fe> Mn> Zn> B> Cu. For macronutrients, accumulation peaks occurred at 28 DAT for N and Mg, at 35 DAT for K and Ca and 49 DAT for N, P, K and Mg. For micronutrients, accumulation peaks occurred at 35 DAT for Fe and Mn and at 42 DAT for Cu and Zn. There is a need to improve synchronism of application by fertigation with accumulation rates for the culture, for most of the studied nutrients. Keywords: Cucumis melo L. nutritional efficiency, nutrient accumulation
