“…Shade tree type has been shown to impact significantly the infestation of black coffee twig borer, Xylosandrus compactus (Eichhoff), a pest which severely affects robusta coffee plantations, especially in Uganda (Bukomeko et al 2018). Bukomeko et al (2018) showed that mature shade trees and sap-exuding herbaceous plants such as Carica papaya could significantly reduce black coffee twig borer on robusta coffee plants as well as an increasing number of sap exuding trees (shading level). Impact of 0 to 30% shade on robusta cup taste (on a 0-10 scale) was not significant, yet more than 30% shade reduces it significantly (Vaast and Raghuramulu 2012).…”

Productivity of coffee plantations is threatened by both climate change and decreasing revenues of coffee growers. Using shade trees might protect against temperature variability, erosion and excessive radiation but there may be trade-offs in productivity and quality. While impacts of shade trees on arabica (Coffea arabica) have been reviewed, a global synthesis on robusta (Coffea canephora) coffee is lacking. We assessed how shade affects robusta growth and productivity, and what are the interactions and trade-offs. We conducted a systematic literature search in Web of Science and CAB Abstracts on 16 December 2019. Thirty papers fulfilled our inclusion criteria of being experimental studies on the impact of overstory trees with approximately half being from Brazil or India. Shade improved robusta tree growth and yield with some contrasting effects on physicochemical and biochemical properties. Shade (> 30%) was associated with reduced beverage quality. Significant interactions between shade and location, rainfall level and robusta clone were found. Among the clones tested, 06V, C153, LB1, GG229 and JM2 showed a higher productivity and growth (from + 17 to + 280%) under moderate shade (41–65%). This is the first meta-analysis of the effects of shade on robusta coffee. By synthesizing data from different studies, we highlight for the first time that the effect of shade on robusta coffee depends on tree age. Shade had positive impacts on older robusta trees (mean of 16 years), while the impact of shade on younger trees was either insignificant or negative. We highlight the importance of both clone type and tree ages. Research gaps included a lack of knowledge on the effects of shade with respect to coffee and shade tree age as well as interactive effects. More in-depth studies are needed to understand the mechanisms of how shade trees affect robusta coffee.

ABSTRAKPenggerek cabang Xylosandrus compactus merupakan salah satu hama penting pada tanaman kopi yang dapat merusak cabang. Setiap klon kopi Robusta memiliki karakteristik genetis, fisiologis, dan morfologis yang berbeda-beda sehingga diduga memiliki tingkat ketahanan yang berbeda-beda pula terhadap serangan X. compactus. Tujuan penelitian adalah mengetahui intensitas serangan X. compactus pada empat klon kopi Robusta (SA 237, BP 308, BP 358, dan RGBN 371) di tingkat lapangan. Penelitian dilaksanakan di Kebun Percobaan Pakuwon dan Laboratorium Terpadu Balai Penelitian Tanaman Industri dan Penyegar (Balittri), Sukabumi, mulai bulan September sampai Desember 2016. Klon kopi Robusta yang digunakan adalah SA 237, BP 308, BP 358, dan RBGN 371 berumur 3 tahun yang ditanam dengan jarak tanam 2,5 m x 2,5 m, menggunakan penaung Gliricidia sepium, Musa paradisiaca, dan Aleurites trisperma. Peubah yang diamati meliputi gejala yang terdapat di dalam lubang, stadia serangga yang ditemukan, diameter lubang gerek, jumlah dan panjang telur, jumlah dan panjang larva, panjang dan lebar imago X. compactus, gejala serangan, serta intensitas serangan. Di samping itu, diamati juga intensitas cahaya matahari dan kandungan air dari cabang kopi sebagai data dukung. Data dianalisis mengikuti pola rancangan acak lengkap (RAL) dengan 4 perlakuan klon kopi dan 6 ulangan. Hasil penelitian menunjukkan bahwa gejala serangan X. compactus terjadi pada bagian cabang kopi dan berpotensi menyebabkan kerusakan tanaman. Dari empat klon kopi Robusta yang diamati, intensitas serangan dan jumlah lubang gerekan tertinggi ditemukan pada klon SA 237 dan terendah pada klon RBGN 371. Kata kunci: Intensitas serangan, kopi Robusta, penggerek cabang, Xylosandrus compactus ABSTRACTXylosandrus compactus (Coleoptera: Curculionidae: Scolytinae) is one main pest in coffee plant which damages the branches. Each Robusta coffee clones has unique genetical, physiological, and morphological characteristics, thus presumably has different resistance levels to X. Compactus. This study aimed to determine the attack intensity of X. compactus on four Robusta coffee clones (SA 237, BP 308, BP 358 and RBGN 371)

“…A recent meta-analysis on the impact of shade trees on robusta coffee showed that shade trees may enhance yield, growth, and biodiversity, yet few studies tested the effects on pests and diseases to allow a general judgment to be made [19]. Arabica and robusta coffee trees do not have the same ecology [20] and recommended fertilizer rates vary [21], which might alter the shade response [10,18,[22][23][24], and the type of shade trees used [25]. Furthermore, C. arabica and C. canephora may not have the same sensitivity to pests and diseases [26].…”

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.
