“…Figure 3 show that the highest fruit production resulted when the boron concentration in soil was 0.6mgdm -3 and 23.5 mg kg -1 in leaves. If one considers 95% of this maximum production the value would be 2,1 kg.ha -1 , quite close to the dosage of 2 kg ha -1 recommended by Teixeira et al (2005) for soils with boron levels lower than 0,2 mg Literature data confirm the beneficial effects of boron to coconut palm tree cultures. Santos et al (2003) reported the positive effects of the micronutrient applied to the leaf axillae.…”

“…General recommendations for the application of boron to coconut plants are that young plants should receive 30 g of borax applied to the 4 th leaf axilla. For producing plants, it is recommended that the micronutrient should be applied directly into the soil -in a dosage of 2 kg ha -1 of B as borax (Sobral, 1997) when analysis indicates levels lower than 0.2 mg dm -3 (hot water) (Teixeira et al 2005). The application of boron directly into the soil is more efficient than foliar techniques due to the low mobility it shows in plant tissues.…”

Boron, one of the micronutrients frequently found in low levels in tropical soils affects nutrition and productivity of coconut palm trees essentially cultivated in tropical climates. The objective of this research study was to evaluate the effect of boron on the nutritional status of the plant and its productivity when artificially applied to the culture soil. The experiment was carried out in a four year old, artificially irrigated, dwarf coconut palm orchard in Brazil, between January, 2005 and October, 2006. The soil was a red yellow Latosol (B: 0.18 mg dm -3 ). The treatments consisted in the application of five boron dosages: zero, 1, 2, 4, and 6 kg ha -1 . In the field, the treatments were arranged according to a completely randomized block design, with four replications. Boron (borax) dosages were applied in equal halves directly into the soil in the months of January and February of 2005. Boron concentration in the soil and plant and plant productivity were evaluated. The higher palm tree production was associated to levels of 0.6mg dm -3 of B in the soil and 23.5mg kg -1 in leaves. Ninety five percent of palm trees maximum production was obtained with the use of a boron dosage of 2,1kg ha -1.

“…The lowest P dose of fertilization recommended in the present study indicates a specific recommendation for the coconut crop under the edaphoclimatic conditions of the municipality of Moju, compared to the recommendation for the state of Pará (LINS and VIEGAS, 2020). In São Paulo State, 120 kg/ha of P 2 O 5 (P resin < 13 mg/dm 3 ) are recommended for an expected yield above 30 t/ha (TEIXEIRA et al, 2005b).…”

“…In the state of Pará, for 160 plants/ha, the recommendation is to apply 192 kg/ha/year of K 2 O for coconut plants with leaf K concentrations between 11 and 12 g kg -1 (LINS and VIEGAS, 2020). In turn, in São Paulo State, it is recommended 300 kg/ha/year of K 2 O (exchangeable K + < 1.6 mmol c /dm 3 ) (TEIXEIRA et al, 2005b).…”

Nutrition and production of coconut palm cultivated with mineral fertilization in the state of Pará

Fertilization greatly affects coconut productivity; nevertheless, information on crop nutrition is relatively scarce for coconut in the state of Pará, Brazil. This study evaluated the effect of fertilization with nitrogen (N), phosphorus (P), potassium (K), and magnesium (Mg) on the nutritional status and coconut yield under the edaphoclimatic conditions of the municipality of Moju, Pará State (Brazil). The experiment was conducted for 10 years on a SOCOCO® Farm and used a randomized block design with three replications. Three levels of P, K, and Mg were used in presence and absence of N. Response to fertilization in the treatments was studied in terms of leaf concentration of macronutrients (N, P, K, Ca, Mg and S) and micronutrients (B and Cl). We also assessed the number of coconuts/plant/year, fresh albumen weight (FAW)/coconut and FAW/ha/year. The results were subjected to the analysis of variance (p<0.05) and the means compared by the Tukey test. In general, N fertilization did not influence concentration of macronutrients and micronutrients in leaves. In turn, P, K and Mg fertilization influenced nutrition of coconut palm. P and K fertilizations, isolated or in combination, increased the production of coconut/plant and FAW/ha. From the 6th year of plant age, 54 kg/ha/year of P2O5 and 96 kg/ha/year of K2O are indicated for the coconut culture in the region of the current study. N fertilization did not influence production parameters and Mg fertilization increased production in the presence of K fertilization.

Resumo -O objetivo deste trabalho foi determinar a influência de níveis de nitrogênio e de potássio aplicados em combinação, via fertirrigação, sobre a produtividade do coqueiro 'Anão-Verde', e a intensidade de ataque do ácaro Aceria guerreronis Keifer (Acari: Eriophyidae Chemical fertilization, attack by Aceria guerreronis and productivity of green dwarf coconutAbstract -The objective of this work was to determine the influence of nitrogen and potassium applied through fertigation, on green dwarf coconut productivity, and the intensity of Aceria guerreronis Keifer (Acari: Eriophyidae) attack. The study was carried out in a commercial orchard of eight-year old green dwarf coconut, in the Neópolis County, Sergipe State, Brazil. The orchard received through microsprinkling (fertigation), since 2000, the following treatments (grams per plant per year of N and K): 135 and 135; 1,890 and 1,890; 810 and 135; 135 and 810; 1,890 and 810; and 810 and 1,890. Four evaluations were done every three months between April, 2003 and March, 2004, on fruit bunches associated with the leaves 14 and 18. Fruit production was influenced by N and K level applied on the coconut orchard, but mite infestation (from 8 to 80% of fruits) and the damage severity on fruits (from 3 to 47%) were not significantly affected by the chemical fertilization.
