Coffee Yield

Coffee agroforestry systems could reconcile agricultural and environmental objectives. While pests and diseases can reduce yield, their interactions with shade and nutrition have been rarely researched, and are particularly lacking in perennial systems. We hypothesized that intermediate shade levels could reduce coffee pests while excess shade could favor fungal diseases. We hypothesized that organic rather than mineral fertilization would better synchronize with nutrient uptake and higher nutrient inputs would be associated with reduced pest and disease damage due to higher plant vigor, yet effects would be less obvious in shaded plots as coffee growth would be light-limited. Using three-year-old trees of Coffea canephora var. Robusta (robusta coffee) in the Ecuadorian Amazon, we compared a full-sun system with four shading methods creating different shade levels: (1) Myroxylon balsamum; (2) Inga edulis; (3) Erythrina spp.; or, (4) Erythrina spp. plus Myroxylon balsamum. Conventional farming at either (1) moderate or (2) intensified input and organic farming at (3) low or (4) intensified input were compared in a split-plot design with shade as the main plot factor and farming practice as the sub-plot factor. The infestation of the following pests and disease incidences were evaluated monthly during the dry season: brown twig beetle (Xylosandrus morigerus), coffee leaf miner (Leucoptera coffeella), coffee berry borer (Hypothenemus hampei), anthracnose disease (Colletotrichum spp.), thread blight (Pellicularia koleroga), and cercospora leaf spot (Cercospora coffeicola). Coffee berry borer and brown twig beetle infestation were both reduced by 7% in intensified organic treatments compared to intensified conventional treatments. Colonization of coffee berry borer holes in coffee berries by the entomopathogenic fungus Beauveria bassiana was also assessed. Brown twig beetle infestation was significantly higher under full sun than under Inga edulis, yet no other shade effects were detected. We demonstrate for the first time how intensified input use might promote pest populations and thus ultimately lead to robusta coffee yield losses.

Mexico is an important producer of organic coffee worldwide. A sector of coffee growers in the municipality of Ixhuatlán del Café, Veracruz, Mexico, use organic amendments as edaphic improvers. Hypothetically, the contributions of these organic fertilizers cause edaphic changes that improve coffee production. Therefore, the objective of this study was to determine changes in soil chemical fertility caused by incorporating fertilizer mixtures made from organic sources, as well as their contribution to improving yield. To verify this hypothesis, four organic fertilizers formulated from dolomite lime, coffee pulp (PC), biol (fermented liquid fertilizer) and a soil improver called PSD® were added to a Cromic Luvisol (cutanic) soil. After three, six and nine months, the contribution of the treatments to the soil variables organic matter, pH, electrical conductivity, nitrogen, phosphorus, and interchangeable bases (K, Ca, Mg, Na) were determined. In parallel, yield was evaluated. The results indicate that six months after application of the treatments, the greatest depletion of the organic sources added occurs, coinciding with a greater release of the nutrients. The dose of 300 g of dolomite lime tree-1 supplied (Treatment 1) was insuff icient to neutralize the strong initial soil acidity (pH 4.3). The coffee pulp and biol utilized are organic fertilizers that, because of their C: N ratio of less than 16, are of rapid mineralization and slightly increased levels of nitrogen, phosphorus and interchangeable bases, reaching only low or moderately low levels. The dolomite lime and PCD® of Treatment 4 improved the pH, Ca and Mg, although these changes are not reflected in increased coffee yield.

Phosphorus (P) is considered one of the nutrients that most limits crop yields, especially in soils with an advanced degree of weathering. To evaluate P dynamics and availability in soil resulting from various P doses and sources and to assess the resulting P content of coffee leaves and the final coffee yield, an experiment was conducted in the municipality of Três Pontas, MG, Brazil, in a Red Argisol (Ultisol) area. Fertilization, except for P fertilization, was performed based on the soil analysis results. The annual P doses tested were 0, 75, 150, 300, 450 and 600 kg ha-1 P2O5. Two P sources, simple superphosphate and magnesium thermal phosphate, were evaluated and compared in the study. A physicochemical analysis of the soil and an analysis of leaf dry matter were performed. The available P content in the soil increased as a result of the applications of the two sources. The leaf P levels stabilized at approximately 1.8 and 1.9 g kg-1 for simple superphosphate and magnesium thermal phosphate, respectively, as a result of the application of approximately 300 kg ha-1 P2O5. The coffee responded to P fertilization in the production phase. Averaged over three harvests, the yield per harvest showed gains of 45.3% and 40.3% for simple superphosphate and magnesium thermal phosphate, respectively, with the application of the highest studied dose, 600 kg ha-1 P2O5.

Set Up

In most cases, in genetic breeding of Arabica coffee, plot size is defined in an empirical manner. It is often based only on the experience of the breeders and the availability of resources, potentially leading to a reduction in precision. Therefore, the aim of this study was to estimate the size of the experimental plot for evaluation of coffee yield. We evaluated two experiments for validation of cultivars with 12 treatments set up in a randomized complete block design with three replicates and plots composed of 50 plants. Each plant was considered as a basic unit. Estimates of ideal plot size were made by maximum curvature of the coefficient of variation, linear-plateau segmented model and by the resampling methods. We discussed the variations in the parameter estimates for different plot sizes. Divergence was seen among the plot sizes estimated by the different methodologies. Increasing the number of plants per plot led to a higher experimental precision to the point that the increase was no longer significant. The plot size recommended for evaluating coffee production is from seven to 19 plants.

<p>An experiment was conducted during the dry seasons in western Hararghe Zone, Eastern Ethiopia at the Haramaya University Chiro Campus to determine the effect of maize stover as soil mulch on yield of Arabica coffee. Five levels of maize stover as soil mulch at a rate of: 0t/ha, 2t/ha, 4t/ha, 6t/ha and 8t/ha were applied in randomized complete block design with four replications from 2008 to 2011. Yield data was recorded during specific phenological stage of the plant. Result from the analysis of variance from the application of maize stover as soil mulch over years showed the presence of significant difference among treatments on bean yield of Arabica coffee. The highest bean yield (1070 kg/ha) and the lowest bean yield (520 kg/ha) were noted at 8 tons/ha and 0 ton/ha, respectively. Similarly, the pooled analysis of variance over seasons corroborated that the effect of maize stover as a soil mulch at a rate of 6t/ha and 8t/ha showed the presence of no significant difference on bean yield of coffee (p&lt;0.05). The result of the present study also elucidated that, the unmulched control plots had the lowest coffee bean yield. While application of 8 tons/ha of maize stover as a soil mulch significantly increased coffee yield both in 2010 and 2011 cropping seasons. Therefore, on the basis of these results, it can be concluded that applying maize stover as soil mulch during the dry seasons at west Hararghe can help to sustain Arabica coffee production. Thus, it is recommended that application of 8tons/ha maize stover as soil mulch can significantly increase the yield of Arabica coffee and sustains its productivity over years.</p>

Dowpon, Roundup, Gramoxone and mixtures of Karmex with Dowpon or Gramoxone applied with different frequency were evaluated for weed control in young sun-grown coffee trees at Adjuntas Agricultural Experiment Substation, located at lat. 18° N. and long. 66°48' W., and at an elevation of 588 m. Gramoxone (0.95 L/ha) applied at one- or two-month intervals provided excellent weed control. Dowpon at 5.65 and 11.30 kg/ha was equally effective on grasses but ineffective on broadleaves. Roundup (1.90 L/ha) provided good weed control without producing detrimental effects on tree growth and yield. The addition of Karmex to the Gramoxone or Dowpon solution to increase effectiveness in control is questionable. Tree mortality was higher and coffee yield lower when Karmex was added to the solution than when either Gramoxone or Dowpon was used alone. When Dowpon was applied at a rate of 11.30 kg/ha, coffee production was significantly higher than production of the remaining treatments, except for that of the application of 5.65 kg/ha of Dowpon at 12-week interval. The production of the latter plots was significantly higher than that of plots in which Karmex (2.26 kg/ha) was added to the Dowpon (5.65 kg/ha) or the Gramoxone solution (0.95 L/ha) and applied each at 12-week intervals. Coffee yield when the weeds were controlled by Roundup (1.90 L/ha) or Gramoxone (0.95 L/ha) was significantly higher than that when Karmex (2.26 kg/ha) was added to the Gramoxone solution and applied every 12 weeks.

Root-knot nematodes negatively impact on coffee yield worldwide. The use of resistant cultivars is the most effective way to manage these pests. The goal of this study was to identify Coffea arabica genotypes with resistance to Meloidogyne paranaensis and M. incognita race 1. Eighteen C. arabica genotypes (EPAMIG’s Germplasm Bank), previously selected for poor host suitability in a M. paranaensis-infested field, plus a resistant and a susceptible standard, were inoculated with these two Meloidogyne species to determine their resistance using nematode reproduction factor (). Accessions for which were considered resistant, while those for which were considered moderately resistant or susceptible, also according to statistical analysis. Five accessions from crossing ‘Catuaí Vermelho’ × ‘Amphillo MR 2-161’, one from ‘Catuaí Vermelho’ × ‘Amphillo MR 2-474’, two from ‘Timor Hybrid (UFV 408-01)’ and the standard ‘IPR-100’ were resistant to M. incognita race 1 with . Four accessions from ‘Catuaí Vermelho’ × ‘Amphillo MR 2-161’, one from ‘Timor Hybrid (UFV 408-01)’, one from ‘Catuaí Vermelho’ × ‘Amphillo MR 2-474’ and the resistant standard ‘IPR100’ were resistant to M. paranaensis (). Field evaluations with parental genotypes showed that plants that originated from progenies ‘Catuaí Vermelho’ × ‘Amphillo MR 2-161’ were resistant to M. paranaensis and also gave a good yield compared to commercial cultivars, showing promising agronomic traits that can be used in breeding programmes to develop new cultivars of C. arabica.
