“…Similar results were found by Laviola et al (2008) in Arabica coffee and Partelli et al (2014) in a super-late clone of conillon coffee in Espírito Santo, with zero accumulation of potassium in the pinhead stage. In the pinhead stage, the low growth rates and dry matter accumulation may be due to the high respiratory rate and intense cell multiplication (Laviola et al, 2007b). In the first sampled pinhead berries (July), a small increase of potassium was more significant (0.25 mg berry -1 ) compared to the two subsequent evaluations (0.19 mg).…”

“…At those times, the coffee fruit is in the rapid expansion, bean formation and maturation stages. These stages are characterised by rapid cell elongation, endosperm filling and increasing sugar content (Laviola et al, 2007b); that is, in this period, there is high nutritional demand for full fruit formation. Similar results were found by Laviola et al (2008) with the highest nitrogen accumulation rates in the rapid expansion, bean formation and maturation stages.…”

“…Thus, berries are the preferred drain in the partition of nutrients during the fruiting stages and the higher the berry production, the higher the demand for nutrients; therefore, attention to nutrition is required at this important stage of the coffee plant. Thus, nutrient delivery must be performed before the peak of element accumulation in the fruit; it must also meet the nutrient demands for vegetative growth (Partelli et al, 2013), which mostly occurs concomitantly with the coffee reproductive stage (Laviola et al, 2007b;Partelli et al, 2014).…”

Knowledge regarding the behaviour and accumulation of nutrients in coffee berries and leaves is important information for the management of fertilisation. Therefore, this study aimed to evaluate the concentration and accumulation of macronutrients in coffee fruits and leaves under different fertilisation regimes in the south western Amazon, Brazil. The experiment was conducted in of plots subdivided by time: the main plots consisted of two fertilisation regimes (fertilised and unfertilised plants), and evaluation periods were in subplots (

“…In coffee, B is the third most absorbed micronutrient by the coffee beans after iron (Fe) and zinc (Zn) or manganese (Mn). One ton of green coffee beans absorbs between 40 and 55 g of B [16][17][18][19]. Boron fertilizer is recommended when the B content in the leaves is below 60 mg.kg −1 and B content is considered to be very low in leaves when its content is below 45 mg.kg −1 [20][21][22].…”

Coffee production around the world is under threat due to climate variability and change, and drought stress will increase in many coffee regions; nutrient management practices can enhance the adaptation capacity of coffee production. Considering that coffee is a crop sensitive to boron (B) deficiency, this research investigated how B nutrition improves resistance to drought stress in coffee under controlled conditions as well as how the interaction with calcium (Ca2+) influences productivity, seed composition, and soil fertility during a production cycle of 5 years. Under controlled conditions for seven months, coffee plants were submitted to water stress with and without B nutrition. In the field, the coffee plantation was exposed to two B rates (0.6 and 1.1 kg.ha−1-year−1) with a fixed calcium (Ca2+) rate and a control without Ca2+ and B. After 9 months of growth and seven months of water deficit, under controlled conditions, the application of B significantly (p < 0.05) reduced the negative effect of water stress on coffee growth. Under field conditions, after a production cycle of 5 years, the application of 0.6 kg B and 77 kg CaO. ha−1.year−1 yielded 14% more than the control without B and Ca2+. An increase in the B rate to 1.1 kg.ha−1.year−1 with the same Ca2+ rate increased the productivity significantly (p < 0.05) by 37% compared to the control. The B application also improved significantly (p < 0.05) the B content in the soil at 0–30 cm. The B treatments influenced the biochemical composition of the green coffee beans, with a significant (p < 0.05) inverse correlation between the B content of the green coffee beans and caffeine and unsaturated fatty acids (UFAs), mainly, oleic, linoleic, and linolenic acids, which are considered negative descriptors of the coffee quality.

“…Temporal variation of foliar boron according to the application of different doses of the element in an oxisol cultivated with coffee Catuaí IAC 144.The B levels in coffee fruits presented increasing linear values depending on this micronutrient dose(Figure 4), which was also observed for leaf content, indicating that the plant the nutrient accumulation mechanism is in the grain. According toLaviola et al (2007) the accumulation of B and Zn in the fruits are larger than other micronutrients, as both have great importance in cell division processes and stabilization of membranes of newly formed cells.…”

Boron doses applied to soil during coffee development

The range between boron deficiency and toxicity in the coffee crop is narrow and the crop toxicity tolerance depends on the soil type, initial soil content and plant age. The objective of this study was to evaluate different levels of boron in the coffee crop during development and grown in a red clayey Oxisol. Treatments consisted of boron applications (zero; 2.48; 4.96; 9.92; 19.8 and 39.68 kg ha-1) in the boric acid form and applied to soil surface in the area of the tree crown projection. The six treatments were outlined in a randomized block design with four replications and ten plants per plot. The cultivar used was Catuaí IAC 144 with sixteen months old, grown in an Oxisol in Campinas, SP, Brazil. Foliar boron content was analyzed as a function of time by regression analysis. The levels in fruit and yield were analyzed by regression according to boron doses. It can be concluded that higher boron doses in the plant can be observed when fruits are at the first development stage. High doses can reduce yield productivity, being each kilogram of applied boron responsible for a reduction of 0.33 coffee bags. ha-1.
