Reducing productivity, outbreak of insects and diseases, and decreasingin physical and cup quality are major problems for Arabica coffee cultivation inmedium altitude. The aim of this study was to investigate the effect of altitude onphysical quality in eight genotypes of Arabica coffee. This research was conductedat two locations i.e. Andungsari Research Station-Bondowoso (1250 m asl. ashigh altitude) and Kalibendo Estate-Banyuwangi (700 m asl. as medium altitude).Randomized complete block design was used with three replications. Collecteddata consisted of outturn, weight of 100 beans, shape bean normality, apparentswelling, bulk density before and after roasting. Combined analysis on the physicalquality traits of green bean showed genotype x altitude interactions on weight of100 beans, percentage of normal beans and percentage of empty bean. Altitudesignificantly influenced coffee outturn. Decreasing in altitude from 1.250 m asl.to 700 m asl. caused declining in the outturn as much 32.9%. BP 700A, K 29, K34, K 79, and K 99 were genotypes that stable to produce normal bean and emptybeans at high and medium altidute, while K 8, K 130, and SIG were genotypeswith high normal beans at high altitude but not stable. Genotype x altitude interactiondid not occur for physical quality of other variables of outturn, bulk densitybefore and after roasting, apparent swelling, percentage of round beans,percentage of elephant beans, and percentage of triage beans. Altitude showedsignificant effect on all of physical quality of bean variables.

In the present analysis, we evaluated the effect of different microbial inoculants on growth and floral responses of Gazania rigens (L.) Gaertn. Two prevailing arbuscular mycorrhizal fungi (AMF) i.e., Funelliformis mosseae and Acaulospora laevis, along with Trichoderma viride and Pseudomonas fluorescens, were examined in a pot experiment. Independent roles of these four microbes and their different combinations were used in sixteen treatments of G. rigens. The experiment was conducted in a polyhouse with five replicates per treatment in a randomized complete block design. The results of microbial inoculants were very effective for growth yield and flowering response over the control. Early flowering was noted in the combination of F. mosseae, A. laevis and P. fluorescens, which also showed the best results for flower head size, flower fresh and dry weight, total chlorophyll, carotene and phosphorus content. Arbuscular mycorrhiza (AM) root colonization (%) and AM spore number were also the highest for the same treatment, whereas the number of leaves, number of buds and root length were maximum in the combined treatment (F. mosseae + A. laevis + T. viride + P. fluorescens). Overall, this study proposes that growers should consider microbial inoculants for the better yield and flower quality of G. rigens.

ABSTRACT The production of Coffea arabica L. clone seedlings through the somatic embryogenesis technique is one of the alternatives of greatest demand for coffee producers. However, clones can face difficulties related to acclimatization carried out under greenhouse conditions, which can increase the production costs. A tested alternative with promising results is inoculation with arbuscular mycorrhizal fungi (AMF) during the seedling acclimatization process. Thus, this study aimed to promote the improvement of the seedling production process through somatic embryogenesis associated with inoculation with AMF. For the production of the clones, seedlings were used in the phase when they presented four pairs of leaves (Clone 1 “Fruiting red Catucaí” and Clone 2 “Acauã”), using “somatic embryogenesis” bioreactors, followed by inoculation with Rhizophagus clarus, Gigaspora margarita and Acaulospora mellea, a mixture of R. clarus and G. margarita and a mixture of R. clarus, G. margarita and A. mellea. After six months, agronomic parameters, leaf nutrient contents and root mycorrhizal colonization were evaluated. The studied clones behaved differently when inoculated with AMFs. Clone 1 showed the best development in the greenhouse, which was determined by the agronomic parameters. Thus, Clone 1 is indicated for the production of vigorous seedlings when associated with inoculation with AMFs.

Coffea Arabica L

In a first step to understand the interactions between Coffea arabica L. trees and mycorrhizae in Ethiopia, an investigation of the current mycorrhizal colonization status of roots was undertaken. We sampled 14 shade tree species occurring in coffee populations in Bonga forest, Ethiopia. Milletia ferruginea, Scheffiera abyssinica, Croton macrostachyus, Ficus vasta, F. sur, Albizia gummifera, Olea capensis, Cordia africana, Ehretia abyssinica, Pouteria adolfi-friederici, Pavetta oliveriana, Prunus africana, Phoenix reclinata and Polyscias fulva. Coffee trees sampled under each shade tree were all shown to be colonized by arbuscular mycorrhizal fungi (AM fungi). Four genera and 9 different species of AM fungi were found in the soils. Glomus (Sp1, Sp2, & Sp3 & Sp4), Scutellospora (Sp1 & Sp2) and Gigaspora (Sp1 & Sp2) were found under all 14 shade tree species, whereas Acaulospora (Sp1) occurred only in slightly acidic soils, within a pH range of 4.93-5.75. Generally, roots of the coffee trees were colonized by arbuscules to a greater degree than those of their shade trees, the arbuscular colonization percentage (AC%) of the former being higher than the latter (signifIcant difference at 0.05 level). Though differences were not statistically signifIcant, the overall hyphal colonization percentage (HC%) and mycorrhizal hyphal colonization percentage (MHC%) were shown to be slightly higher under coffee trees than under their shade trees. However, the differences were statistically significant at 0.05 level in the case of HC% values of coffee trees under Pouteria adolf-friederici and MHC% under Cordia africana. Spore density and all types of proportional root colonization parameters (HC%, MHC%, AC% and vesicular colonization percentage, VC%) for both coffee and shade trees were negatively and significantly correlated with organic soil carbon, total N, available P, EC and Zn. Correlation between arbuscular colonization for coffee (AC%) and organic carbon was not significantly positive at a 0.05 level. Incidence of specific spore morphotypes was also correlated with physical and chemical soil properties. Results indicate that AM fungi could potentially be important in aforestation and help to promote coffee production activities in Ethiopia providing an alternative to expensive chemical fertilizer use, and would offer management methods that take advantage of natural systems dynamics that could potentially preserve and enhance coffee production. Key words: aforestation; agroforestry, coffee groves, ecology, integrated production systems, rhizosphere, sustainable agriculture, symbiosis

A study to determine the effect of various types of mixed planting media on Arabica coffee seed germination was carried out in April to May 2019, located in the Experimental Garden of the Faculty of Agriculture, University of Winaya Mukti, Tanjungsari, Sumedang. This study used a randomized block design (RBD) consisting of 4 treatments and 5 replications. The planting media used in this study were mixed media consisting of A = soil; B = mixture of soil and manure (1: 1); C = mixture of soil and charcoal (1: 1); D = mixture of soil, manure and husk charcoal (1: 1: 1), The results of the study showed the planting media in the form of soil, a mixture of soil with manure or charcoal husk, and the mixture of the three did not affect the germination of seeds, but the use of in the form of a mixture of soil with manure and husk charcoal can increase the germination index compared to the media in the form of soil without mixture.

ABSTRACT The purpose of this paper was to evaluate the effects of the interference by Urochloa brizantha on coffee seedlings inoculated with arbuscular mycorrhizal fungi. A randomized block design and a 4 x 2 layout was used, where factor A was constituted by seedlings inoculated with Rhizophagus clarus, Claroideoglomus etunicatum and Dentiscutata heterogama, as well as some that were not inoculated, and factor B, constituted by plants in competition or alone. The sowing was conducted on washed sand to produce the coffee seedlings, which, during the matchstick stage, were transplanted into polyethylene bags, and inoculated when showing six pairs of leafs. Then, they were transplanted into pots where they were subjected to interference from two plants of U. brizantha for 90 days, during which time their growth and nutrient accumulation were evaluated on the leaves. As a result, an interaction between the following factors was observed: plant height, leaf area, shoot dry weight, dry weight for roots and P, Mg and Zn content in coffee seedlings. The damaging effect on the growth and P accumulation caused by the weed was reduced in coffee seedlings inoculated with mycorrhiza. Another conclusion was that the inoculation factor increases the competitive power of coffee seedlings.

Colombia is among the countries of Latin America that produce about 80% of f ine or “prime” cocoa of the world; however, cocoa in Colombia has limitations related to the presence of cadmium (Cd) in some soils where it is grown and this reduces the safety of the product. The objective of this study was to evaluate the absorption of cadmium in a cocoa pattern (IMC 67) in association with arbuscular mycorrhizal fungi (AMF) to determine their potential use as Cd immobilizers in medium and long-term. A randomized complete block design with three replications and 20 treatments was established, in 4 × 5 factorial arrangement, one control, three types of mycorrhizae (Glomus macrocarpum, Rhizoglomus intraradices and AMF-native) and f ive Cd doses (0, 6, 12, 18 and 24 mg kg-1). Plant height, dry weight of stem, leaves and roots as well as Cd concentration in stems, leaves and roots were measured. The results showed that cacao plants translocate the Cd easily, that is, they can live under these conditions since it was found in all organs (stems, leaves and roots); however, the treatment inoculated with AMF‑native decreased signif icantly the accumulation of Cd in all the organs evaluated. These results conf irm the benef icial effects that AMF have to alleviate the stress that plants shows when translocating heavy metals such as cadmium.

Coffea Arabica L

Arbuscular mycorrhizal fungi (AMFs) play an important role in soil improvement, leading to the enhanced growth and yield of the host plants. The diversity, abundance, and richness of AMFs were evaluated in eight coffee plantations (Coffea arabica L.) with different erosion degrees. The results indicated that 26 AMFs morphotypes scattered across four genera were recovered and included five species. Funneliformis species were the most dominant representatives of the total isolates followed by Claroideoglomus, Rhizoglomus, Gigaspora, Acaulospora, Glomus, Diversispora, Septoglomus, and Scutellospora. The highest diversity and richness were found in non-eroded agroecosystems, followed by sites with a minimum erosion, and the lowest values were reported within the highly eroded agroecosystems. These results suggest that eroded soil affects AMF fungi, creating the need to carry out studies that allow for the implementation of cultural practices where biodiversity and soil are preserved.
