The objectives of this study were to explore the effectiveness of simple sequence repeats markers (SSRs) in detecting polymor- phism and to assess the extent of genetic diversity and relationships among ex-situconserved Arabica coffee accessions. Sixty-two forest coffee accessions planted in the experimental plot of the Ethiopian coffee breeding program were evaluated using 14 SSR markers. These markers amplified a total of 100 alleles, varying from four to ten alleles per locus, with an average of 7.2 across all loci. The rate of polymorphism ranged from 75 to 100, with a mean value of 96.4 across the accessions. The polymorphic information content (PIC) varied from 0.26 to 0.92, with a mean value of 0.70. The genetic similarity coefficient values between 72% possible pair-wise combinations ranged from 0.18 to 0.50, with overall mean value of 0.44.The unweighted pair group method with arithmetic mean (UPGMA) dendrogram based on Jaccard’s genetic similarity grouped the accessions into five main clusters and two singletons at <0.47 similarity coefficient value. These results indicate the effectiveness of the SSR markers in detecting polymorphism and the presence of a high level of genetic diversity and distant relatedness among the studied coffee accessions. The observed diversity could be exploited in the future coffee breeding program to develop heterotic hybrid coffee varieties through crossing of divergent parental lines.

Over the years, there has been a shift from the traditional cocoa agroforestry system to full-sun cocoa production. Due to extreme exposure to high temperatures, sunlight and drought, the photosynthetic mechanism of cocoa is altered, reducing yield.Cocoa agroforestry provides economic, social, and ecological benefits and plays subsistence functions such food and fuelwood. The study was carried out to assess cocoa agroforestry systems based on shade and its effect on yield in the Offinso Municipality of Ghana. The study aimed to identify the types of cocoa agroforestry systems based on shade, determine the factors affecting cocoa agroforestry systems and assess the impact of shade regime on cocoa yield in the municipality. Purposively cocoa farmers were randomly and were adminis-tered with questionnaires. The study revealed that farmers in the Offinso Municipality practice all types of cocoa agroforestry systems (full sun, low shade, medium shade, and heavy shade). The cultivation of cocoa under medium shade (15–18 trees ha-1) proved to be beneficial and essential for the long-term production ofcocoa. The medium-shade cocoa recorded a higher average yield of 1576 kg ha-1. Six common shade trees identified include Terminalia superba (ofram), Ricinodendron heudelotii (wawa) and Chlorophora excelsa (odum). Some challenges faced as a result of practicing the cocoa agroforestry system were pest infestationand diseases such as that of the black pod. Cocoa agroforestry still holds the key to sustainable future outputs in cocoa production as it drives the realization of SDG goal 13 (climate action). There is therefore the need to educate farmers on managing their farms with trees for optimum ecological and economic benefits.

The study area was Nigeria and information were collected from one hundred and eighty farmers using well-structured question- naires. Descriptive statistics, budgetary analysis and linear regression were used for analysis in this study. The study revealed that twenty-seven farmers practised sole cocoa cropping, seventy-five farmers practised cocoa/arable cropping and seventy-eight farmers practised cocoa/tree cropping systems, respectively. The mean age of farmers in sole cocoa cropping system was 49.3 years, for cocoa/ arable cropping system the mean age was 47.8 years while for cocoa/tree cropping system the mean age of farmers was 47.2 years. For sole cocoa cropping system, the total cost (TC) was USD 7,764; the gross revenue (GR) was USD 43,774 with USD 36,009 as profit made from the cropping system. The TC for cocoa/tree cropping system in Nigeria was USD 18,003, GR was USD 124,104 and the profit was USD 106,102. Similarly for cocoa/arable cropping system, the TC was USD 16,215, GR was USD 109,849 and profit was USD 93,634. The determinants for the three cocoa cropping systems were age, gender, marital status (married), educational level (primary), cost of seedling, cost of fertilizer, cost of fungicide, cost of herbicide, labour cost for bush clearing, land preparation, weeding and planting.

Drought that occurs in the dry season inhibits growth, reduces yields, and even death of plants. Not all plants are equally resistant to drought conditions. Drought-resistant coffee clones usually develop several resistance mechanisms, including the formation of specific compounds to protect cells and tissues from damage caused by drought stress. Therefore, the objective of this study was to investigate the influence of watering interval on the seedling growth of three clones of Arabica coffee. This study used applying intervals of watering every two, four and six days as first factor and three Arabica coffee clones as second factor, namely Andungsari 2K, S 795, and Andungsari 1. The experimental design used a factorial completely randomized design where every treatment combination had three replications. This study on Arabica coffee nursery lasted for three months. Results obtained in this study demonstrated that combination of watering every four and six days on Andungsari 2K clone had the best values on several observed variables. Number of stomata, leaf thickness, fresh root weight, and root dry weight were larger for watering every six days on the Andungsari 2K clone, meanwhile leaf number, stem diameter, fresh and dry weight of leaves were larger for watering every four days on Andungsari 2K clone. This study showed that there was an interaction between watering intervals and Arabica coffee clones on plant growth.

Therefore, the aim of this study was to determine the coffee consumption habits and the perception of its effect among college students in Mumbai. The study was performed using convenient sampling method with a sample size of 234 students studying in different colleges from Mumbai. This study collected information about the characteristics of the students participated, coffee intake habits and the perception of its effect on consuming coffee.
