The management of micronutrients in oil palm trees in the Brazilian Amazon is still underdeveloped; thus, information on plant demands and their interactions with other nutrients is required to create adequate management procedures. The objective this work was to evaluate the effects of phosphate, potassium, and magnesium fertilization on micronutrient concentrations in leaves of oil palm trees. The experiment was carried out in the Brazilian Amazon in a randomized block design in a 4 x 2 x 3 x 2 factorial scheme, using four phosphorus levels, two phosphorus sources (natural phosphate and triple superphosphate), three potassium levels and two magnesium levels. Phosphate fertilization increased the concentrations of boron, chlorine, and iron in leaves, while copper and manganese concentrations in leaves decreased with increased doses of phosphorus. Among the phosphorus sources, triple superphosphate provided higher chlorine concentrations in leaves. Potassium fertilization increased only chlorine concentrations in leaves, while magnesium supply did not alter micronutrient concentrations in leaves. Thus, phosphorus and potassium fertilizers are essential to provide adequate micronutrient concentrations in leaves of oil palm trees.

The objective of this work was to evaluate the effect of different doses of limestone, phosphorus, and potassium on the initial development of Anacardium humile (Cajuzinho-do-cerrado) seedlings. The experiment was conducted in a greenhouse. A randomized block design was adopted in a 3x4x4 factorial scheme (liming x phosphorus x potassium doses). The treatments consisted of three liming doses (0; 40; and 70% of base saturation), four doses of potassium chloride with 60% of K2O (0; 60; 120; and 180 kg ha-1), and four doses of triple superphosphate with 46% of P2O5 (0; 80; 160; and 240 kg ha-1), with six replications. The following characteristics were evaluated: stem diameter (SD), plant height (PH), root length (RL), shoot dry matter (SDM), and root dry matter (RDM). The data were submitted to analysis of variance and the averages were compared by Tukey’s test (p < 0.05). It was concluded that there was no influence of phosphorus doses on the initial development of A. humile seedlings and that there was a response to the association between liming and potassium chloride in vegetative growth.

<p>ABSTRACT</p><p>Effective and efficient fertilization is affected by fertilizer dose, and therefore information on the appropriate dose of a single fertilizer for oil palm will be beneficial to increase the efficiency and effectiveness of fertilization in oil palm plantations. The objectives of this research were to study the response patterns and to determine optimum rate of single fertilizer package related to the growth of one year old oil palm trees. The experiment was conducted from March 2013 to February 2014 at IPB-Cargill Teaching and Research Farm of Oil Palm, Jonggol Bogor. The experiment was arranged in randomized block design with one factor and replicated three times. The treatments were four single fertilizer package as followed: control, 300 g urea + 375 g SP-36 + 350 g KCl + 25 g boric acid + 25 g CuSO4.5H2O, 600 g urea + 750 g SP-36 + 700 g KCl + 25 g boric acid + 25 g CuSO4.5H2O, 900 g urea + 1125 g SP-36 + 1050 g KCl + 25 g boric acid + 25 g CuSO4.5H2O per plant. The result showed that application of single fertilizer package significantly increased the growth of young oil palm linearly as shown by plant height, stem girth, leaf area of frond number 9, chlorophyll and P content of the leaves and quadratically on leaf number at the last observation. The optimum rate of single fertilizer for one year old oil palm trees had not been attained at this research because the plant growth response to fertilization was still linear.</p><p>Keywords: inorganic, leaf frond number 9, optimum rate, growth response, stem girth</p>

Natural pastures are important ecosystems that both contribute to biodiversity conservation and provide an important source of income, especially for cattle ranchers. While these pastures yield fairly low productivity, they can be improved by increasing soil fertility and introducing species with high productive potentials. In this sense, the purpose of this study was to evaluate the effects of applying limestone and phosphorus, as well as introducing cool-season species with a mixture of species dominated by Schizachyrium tenerum Nees, into a natural pasture in the Catarinense Plateau. The experiment was conducted from January 2010 to December 2013; the treatments consisted of superficial distribution of limestone in proportions of 3.6, 7.2, 11.0, and 14.4 t ha-1, as well as distribution of phosphorus in the form of triple superphosphate in proportions of 35, 70, 105, and 140 kg of P2O5 ha-1. In addition, cool-season species were overseeded. The experiment consisted of a randomized block design with subdivided plots and three replications. Limestone was applied to the main parcel, whereas phosphorus was applied to the subplots. There was no interaction between the levels of limestone and phosphorus. The application of 11.0 t ha-1 of limestone yielded the highest forage production, with 3,932.2 kg of dry matter (DM) ha-1 during the second year. Red clover was the species that best reacted to the additions, with levels of 7.2 and 11.0 t ha-1 over the 4 years. In addition, phosphorus provoked a positive response throughout the experiment. The highest forage production was observed during the second year, with an addition of 140 kg P2O5 ha-1 (4,419.4 kg DM ha-1). Only one-eighth of the recommended amount of limestone (3.6 t ha-1) allowed for the establishment and persistence of the legumes introduced into natural pastures. These additions, associated with increasing levels of phosphorus, yielded linear growth in the production of forage in natural pastures with a mixture of species dominated by Schizachyrium tenerum Nees.

ABSTRACT Although there are evidences that the proper supply of mineral nutrients to plants relieves water stress, little is known on the approach of how the drought affects the absorption and accumulation of nutrients by distinct sugar cane genotypes, or in different parts of a same plant. Thus, the objective of this study was to determine the content and accumulation of N, P and K in the aerial part of plant from three genotypes of sugar cane, submitted to three water potentials in the soil, and check the relationship of these variables with the tolerance of plants to prolonged drought. In order to access this objective, an experiment under greenhouse conditions, comprised by a fatorial 3 × 3, in a randomized block design, and four replicates was carried out. After 90 days from treatment imposition, the plant transpiration rate, plant dry mass, concentration of N, P and K were determined in leaves and culms, as well as in total plant shoot were measured. It was found that tolerance to drought in sugar cane is related to higher levels of N and K in the leaves and stems, and larger accumulations of K and P in the plant shoot. There is high positive correlations among accumulation of N, P and K in the plant shoot and dry matter production by plants submitted to drought. There are intermediate correlations among plant transpiration and nutrient uptake by plants under drought. Plants of the genotype SP81-3250 are more tolerante to prolonged drought, than the RB855453 and IACSP95-5000 plants.

The purpose of this research was to discover the effect of solid and NPK fertilizer, as well as the interaction of solid and NPK fertilizer on the growth and production of green eggplant. This research used a factorial randomized block design with two treatment factors, namely the first factor: Administrationof oil palm solid which consisted of 4 levels of treatment, namely: S0 = No palm oilwaste solid; S1 = Administration of palm oil waste solid at 0.5 kg/m2; S2 = Administration of palm oil waste solid at 1 kg/m2; S3 = Administration of palm oil waste solid at 1.5 kg/m2. The second factor is the addition of NPK fertilizer per plant (J) consisting of 3 levels of treatment, namely: J0 = 0 g/plant; J1 = 5 g/plant; J2 = 10 g/plant. The results showed that solid treatment significantly affected the plants height at ages 2, 4, and 6 MST, flowering age, production per plant, and production per plot. The treatment of Solid S3 produced the highest plants aged 2, 4, and 6 MST, respectively (21.78 cm), (53.45 cm), and (77.78 cm), the fastest flowering age (32.89 days), highest production per plant (1748.77 g), and highest production per plot (21.89 kg). The NPK treatment significantly affected the plants height at ages 4 and 6 WAP, flowering age, production per plant, and production per plot. The NPK J2 fertilizer dosage treatment produced the highest plants aged 4 and 6 WAP, respectively (47.83 cm), and (75.84 cm), the fastest flowering age (32.91 days), the highest production per plant (1562.91 g), and the highest production per plot (19.86 kg). The interaction treatment of the NPK fertilizer and solid administration did not significantly affect all parameters. The combination of S3J2 produced the highest plants aged 2 and 6 WAP, respectively (22.33 cm) and (79.67 cm), the fastest flowering age (32.33 days), the highest production per plant (1816.67 g), the and highest production per plot (22.49 kg).

ABSTRACT Castor bean plants are susceptible to aluminum (Al) in the soil, requiring adequate management techniques for their cultivation in acid soils containing high Al levels, as it occurs in tropical regions. This study aimed to assess the Al tolerance of castor bean lines. A randomized block design, in a 2 x 9 factorial scheme, with four replicates, was used. The treatments consisted of presence and absence of Al, as well as nine castor bean lines (CRZ H06, CRZ H11, CRZ H12, CRZ H15, CRZ H17, CRZ H18, CRZ H19, CRZ H22 and FCA). Based on a distribution into quartiles, the lines were divided into two groups. The Al-tolerant group contained the CRZ H06, H11 and H17 lines, while the group susceptible to Al was composed of CRZ H12, H15, H18, H19, H22 and FCA. The FCA and CRZ H17 lines showed the highest growth, when cultivated without Al.

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.

Neste cenário, a irrigação surge como um importante fator de produção, além de promotor da máxima produtividade e da qualidade do produto. O objetivo deste trabalho foi identificar um manejo adequado da irrigação por gotejamento, com minitanque evaporimétrico, para o desenvolvimento e produção do pepino japonês em ambiente protegido. O ensaio foi realizado na Fazenda Experimental da Universidade Federal Rural da Amazônia, município de Igarapé – Açu/PA. Utilizou-se o delineamento em blocos casualizados com cinco tratamentos e quatro repetições, aplicando-se lâminas de 30, 60, 90,120 e 150% baseadas na evaporação do minitanque. Observou-se que de modo geral, tanto a deficiência quanto o excesso hídrico afetaram negativamente as variáveis analisadas. Os melhores índices de produtividade e crescimento foram encontrados nas lâminas de 90 e 120% da ECA e a maior eficiência do uso da água, obtida com as menores lâminas de irrigação, sendo o valor máximo, de 2842,53 kg ha-1 mm-1, encontrado no tratamento com 30 % da ECA.   Palavras-chave: Cucumis sativus L.; evaporação; gotejamento; manejo de água.     RODRIGUES, T.C.A.; LIMA JÚNIOR, J.A.; DE MELO SOUZA, R.O.R.; OLIVEIRA NETO, C.

TECHNICAL FEASIBILITY OF JAPANESE CUCUMBER PRODUCTION SUBMITTED TO DIFFERENT IRRIGATION BLADES     2 ABSTRACT   Water deficiency is usually the factor that most limits the productivity and quality of vegetables. In this scenario, irrigation appears as an important factor of production, besides promoting the maximum productivity and product quality. The objective of this work was to identify an adequate management of drip irrigation, with reduced pan, for the development and production of japanese cucumber in a protected environment. The experiment was carried out at the Experimental Farm of the Rural Federal University of Amazônia, county of Igarapé - Açu - PA. A randomized block design with five treatments and four replicates was used, with slides of 30, 60, 90, 120 and 150% based on the evaporation of a modified pan. It was observed that, in general, both the deficiency and the water excess negatively affected the analyzed variables. The best productivity and growth indexes were found in the 90% and 120% ECA slides and the highest water use efficiency obtained with the lowest irrigation depths. The maximum value was 2842.53 kg ha-1 mm- 1, found in the treatment with 30% ECA.   Keywords: Cucumis sativus L.; drip irrigation; evaporation; water management

Abstract Background: Nutrient deficiency leads to a high fruit abscission rate in Sapindus mukorossi Gaertn. (Soapberry), which is one of the most widely cultivated biodiesel feedstock forests in China. Exogenous sucrose can provide a solution to nutrient deficiency and fruit abscission, which was applied to whole trees at two stages, 20 days before blooming (DBB stage) and fruit abscission (DBFA stage). Six sucrose concentrations, 0%, 1%, 1.5%, 3%, 5% and 7%, were sprayed three times at a completely randomized block design with 5 replications and 6 treatments. 13CO2 labelling experiments were carried out after the 3 sprayings. Results: (1) In the DBB stage, the 3% treatment significantly increased the inflorescence fructose and glucose contents 1-1.2 times, also resulted in the highest fruit GA3, leaf IAA, fruit IAA and fruit ZT contents, while it decreased the inflorescence ABA from 16 μg/g to 4 μg/g. (2) The 1.5% and 3% treatments significantly increased the carbohydrate content and decreased fruit ABA content to 30%-50% of the control level in the DBFA stage. (3) High-concentration sugar treatment (over 3%) increased the nitrogen, phosphorus, and potassium contents, which decreased the calcium and magnesium contents. (4) The 13C-dispatching ability of the inflorescence was 3 times greater than leaves under high-concentration sugar treatment in the DBB stage. Supplying 1.5% sucrose nearly doubled the allocation capacity in the DBFA stage. (5) The source-sink nutrient migration pathway showed that leaf and fruit sugars were directly correlated via phosphorus. Fruit fructose and glucose contents affected the leaf mineral element contents. Conclusions: It can conclude that exogenous application of 3% sucrose in the DBB stage and 1.5% sucrose in the DBFA stage can increase the sink nutrition allocation capacity, and phosphorus is the main mineral element correlated with leaf and fruit sugars.
