“…The cl obtained by the BL method may be closer to the actual growing conditions of a coffee tree in full production, since studies have shown that perennials have a tendency to require less P during development (Novais et al, 1982;Valadares et al, 2014). This may be one of the reasons for the low response of coffee trees in production to phosphate fertilization; hence, it is important to establish the critical levels of P for each stage of plant growth, aiming at rational management of fertilization for coffee and meeting its demand throughout the crop cycle (Guimarães and Reis, 2010).…”

Research focused on adequate nutrition of plants is essential in modern coffee production to increase yield and develop more efficient management strategies with greater environmental and economic sustainability. The objectives of this study were to establish critical and optimal levels of soil fertility properties for high yielding Arabica coffee crops using the Boundary Line method and, then, relate the macronutrient contents in the diagnostic leaf of coffee to the macronutrients available in the soil using the Quadrant Diagram of the Plant-Soil Relationship (QDpsR). The study made use of a soil chemical analysis database, leaf macronutrient contents, and Arabica coffee yield from five representative coffee-growing regions in Minas Gerais. An analysis of data consistency was performed, and relative fruit yield (RFY) was related to the soil organic matter (SOM), P, K, Ca, and Mg contents in the soil, establishing the boundary line (BL) in each graph. Equations were adjusted from the BL points, and the equation that best fit was selected. Using the QDpsR method, the response plane was divided into four quadrants, where the total leaf contents of N, P, K, Ca, Mg, and S were plotted as a function of the contents of SOM, P, K, Ca, and Mg in the soil, on the y and x axes of the Cartesian coordinate system. The regression equations were adjusted to the pairs of points (y, x) of quadrants III and I and were used to estimate the macronutrient sufficiency ranges from the critical and optimal levels in the soil. The BL method was used to determine the class of good soil fertility for SOM, P, K, Ca, and Mg. The QDpsR method allows determination of response curves for leaf content as a variable of soil contents, making it possible to estimate the sufficiency ranges in the diagnostic leaf of coffee: 33.4-35.8 g kg-1 of N, 1.4-1.6 g kg-1 of P, 24.4-27.0 g kg-1 of K, 11.9-13.6 g kg-1 of Ca, 3.8-4.5 g kg-1 of Mg, and 1.4-1.8 g kg-1 of S; which were consistent with the sufficiency ranges considered suitable for the crop. This study demonstrated the importance of leaf analysis as a tool for evaluation of the nutritional status of Arabica coffee since the technique is consistent with the theoretical principles underlying it.

“…Inconclusive responses of the adult coffee plant to P fertilization have been reported in the literature [53] [54] because the coffee plant is considered not very responsive to fertilization with P during the production period [54]. So, P fertilization studies at coffee planting are important to develop healthy and productive orchards.…”

Phosphorus (P) plays a crucial role in plant growth by aiding in the development of strong roots, promoting flower and fruit formation, and aiding in photosynthesis. Studies to improve P fertilizers efficiency in coffee orchards are necessary due to the need for better efficiency and the lack of information on enhanced efficiency P fertilizers. This study aimed to investigate the effect of MAP coated with anionic polymers (Policote) on coffee orchard development. A coffee trial was carried out in a randomized block design with three replications. The treatments, applied at coffee planting, were arranged in an incomplete factorial (2 × 4) + 1, using two P sources (MAP and Policote coated MAP), four P rates (40, 80, 120, and 160 g P 2 O 5 plant −1 ) and control (without application of P fertilizer). Plant height was evaluated in the 2016/2017, 2017/2018, and 2018/2019 seasons, while coffee bean maturation, yield, and agronomic P efficiency use were evaluated in the last two seasons. P fertilization did not affect coffee bean maturation and increased coffee yield in 31-month-old plants when differences among P sources and rates were observed. Using Policote-coated P fertilizer resulted in higher yields at the same P rate, as well as similar yields at a lower P rate, compared to conventional fertilizer. Policote-coated P fertilizer can be used as an enhanced efficiency fertilizer and is an efficient way to deliver required P to plants. The target for reducing farm investment, increasing agricultural profits, preserving phosphatic rock reserves, and avoiding the overuse of phosphate fertilizer could be realized through the rational use of enhanced efficiency fertilizers.

“…Gallo et al (1999), por sua vez, analisando dois tipos de solo, constataram incrementos produtivos somente em solos com menores índices de fósforo. Já Valadares et al (2014) não observaram efeito da adição de fósforo (dose máxima de 400 kg ha -1 ano -1 de P2O5).…”

“…Outra hipótese pode estar relacionada à concentração inicial do fósforo no solo. De acordo com Valadares et al (2014), as respostas do cafeeiro à fertilização fosfatada não podem ser generalizadas e que ocorrências positivas se devem à baixa disponibilidade do macronutriente no solo (AMARAL et al, 2011;GUZMAN, 2017), característica comum em solos de lavouras cafeeiras no sul de Minas Gerais (CORRÊA et al, 2001). De acordo com Corrêa et al (2001), 72% das lavouras cafeeiras estudadas apresentaram níveis médio ou baixo de teores de fósforo no solo (2 mg dm -3 a 4 mg dm -3 e 4,1 mg dm -3 a 6 mg dm -3 respectivamente), conforme as classes de fertilidade do fósforo para manutenção da lavoura de café proposto pela Comissão de Fertilidade do Solo do Estado de Minas Gerais -CFSEMG (GUIMARÃES et al, 1999).…”

Assim, objetivou-se avaliar o desempenho técnico e econômico do cafeeiro fertirrigado com doses de fósforo e lâminas de irrigação. O cafeeiro estudado foi o da espécie arábica, cultivar Topázio MG-1190. O experimento foi implantado em janeiro de 2010, com diferenciação dos tratamentos a partir de novembro de 2011, obtendo-se a primeira produção em 2012, e as demais nas duas safras subsequentes (2013 e 2014). O delineamento experimental foi em blocos casualizados no esquema fatorial 5x4, sendo os tratamentos compostos por cinco frações (Ki) da lâmina de irrigação requerida (0,4, 0,7, 1,0 1,3 e 1,6), quatro doses de fósforo (0, 80, 240 e 720 kg ha-1 de - P2O5) e quatro repetições. Em resumo, observou-se que os tratamentos referentes às menores lâminas de irrigação e dosagens de fósforo foram suficientes para suprir as demandas da cultura. As doses de fósforo de 240 kg ha-1 associado a frações acima de 0,7, e doses de 720 kg ha-1, apresentaram-se inviável economicamente. Verificou-se que possivelmente solos com ótimos níveis de fósforo o cafeeiro não responde a adubação fosfatada suplementar.

TECHNICAL AND ECONOMIC PERFORMANCE OF FERTIRRIGATED COFFEE WITH DIFFERENT PHOSPHORUS CONCENTRATION 2 ABSTRACT Many studies show coffee crop as a responsive plant when high doses of phosphorus (P) are applied, contradicting the current fertilization recommendation. Therefore, this study aim was to evaluate technically and economically the application of doses of phosphorus with different irrigation depths in a soil that already has high level of fertility. Arabica coffee variety Topázio MG-1190 was planted in January 2010 and the treatments variation started in November 2011. The first harvest was 2012 following by other two in 2013 and 2014. The experimental design was random blocks in factorial 5x4x4. The five irrigation depths used were based on (Ki) fraction of irrigation requirement (0.4, 0.7, 1.0, 1.3 and 1.6), the four levels of phosphorus applied were (0, 80, 240 and 720 kg ha-1 of P2O5), and four replicates were used. The treatments using lower irrigation depth and phosphorus doses showed to be enough to supply crop demand. Doses of 240 kg ha-1 associated with fractions higher than 0.7 were economically infeasible, showing that in soils already containing high levels of phosphorus, the coffee crop does not respond to supplemental application of this element.
