Abstract An experiment was conducted at Tepi National Spices Research Center for five years, to determine the optimum planting space and vertical numbers that promote growth and yield of hybrid Arabica coffee variety. The treatments consisted of three levels of planting space (2.5 m x 2.5 m, 2.5 m x 2.0 m, 2.0 m x 2.0 m) and three vertical number...

A field experiment was conducted at Awada Agriculture Research Sub center experimental site in two sets between 2005 and 2015 having two promising improved south Ethiopian coffee selections with distinct canopy class: open type (13/77) and compact type (85/238) to determine appropriate plant density and number of verticals for enhanced yield and yi...

The study was conducted to evaluate different harvesting and postharvest handling methods on the inherent raw quality characteristics of Hararghe coffee. The experiment was designed as a factorial combination of two harvesting (selective and strip harvesting) and six postharvest processing (dry processed dried on bare, cemented and plastic sheet gr...

A field experiment was conducted at Tepi National Spice Research Center for two consecutive years, to find out optimum planting material, population density and method of planting to enhance turmeric yield and quality at Tepi southwestern Ethiopia. Twenty four treatment combinations consist of 3 levels of planting material (Mother Rhizome, Primary...

Coffee the backbone of Ethiopian economy; nonetheless, productivity and quality have remained very low. Among others, improper postharvest processing largely contributes to the decline of coffee quality. Yet, there is limited effort exerted to optimize postharvest processing to improve Ethiopian coffee quality. Thus, this study was conducted to det...

In an attempt to investigate the efficiency of close spacing and determine the optimum density for the approved coffee berry disease (CBD) resistant selections, field experiments were conducted at Tepi, Wenago, and Gera Research Centers for eleven consecutive years (1988/89-1998/99). A randomised complete block design was used to assign seven popul...

Coffea arabica is originated in the montane rainforests of southwest Ethiopia and thus it is a shade-loving plant, but thrives best in moderate shading. The original forest habitat is being disturbed largely due to deforestation practice in parallel with an increasing population pressure. Therefore there is an urgent need to identify prominent coff...

... Those appear not to emphasize the economic, cultural, and symbolic significance of the enset plant in the community. Various studies are being conducted on the enset plant (Ashenafi et al., 2020;Gemechu et al., 2021;Mekonnen et al., 2020;Tsegaye and Struik, 2002;Yemataw et al., 2016;Zewdie et al., 2008). The positive aspect of these studies is that they attempted to investigate and explore the production, cultivation, and consumption of enset in Ethiopia. ...
... As a result, the banana tree competes less for water with the coffee tree than certain other shade trees [26]. Enset intercropped with coffee has also been reported to increase coffee yields [27], with significant yield differences between mono-cropped and coffee-Enset intercropping systems, which contradicts the findings of other researchers who found a significant yield difference in monocropped and intercropped banana with coffee systems. ...
... According to [48], the lower population density of coffee trees is a major factor causing a low yield per unit area. Several authors reported the strong correlation of coffee yield with the population density of coffee trees per unit area [12,34,47,[49][50][51][52]. ...

... Rhizome FW (from now on referred to as "yield") is greatly affected by the root zone volume or by planting density, both of which affect rhizome competition for space and resources such as water and nutrients. However, most research related to planting density of these crops has been conducted in the field using soil, where yield is also affected by various edaphic and environmental factors (Islam et al., 2002;Nair, 2013;Temteme et al., 2017;Tiwari et al., 2019). Whiley (1990) found increases in ginger yield of up to 44% in response to higher planting density. ...
... Both sun-drying and wet processing methods are used in Ethiopia, which account for 70 and 30% of the coffee produced in the country, respectively (Jacquet et al. 2008). According to Ameyu et al. (2017), the dry-processed method coupled with drying coffee on mesh wire was best in producing coffee beans with high raw quality. In contrast, dry processing using bare ground produced inferior coffee for all raw quality attributes. ...
... N recommended fertilizer rate was applied at the stage of first leaf, second leaf and forth pair of leaf. Nursery management's practices watering, mulching, weeding were conducted according to Tesfaye [22]. ...
... The low-input coffee production system with the occurrences of maximum biodiversity, environmental sustainability, and ecological services (Taye, 2010) should deserve due attention and needs to be supported, among others, through smallholder certification and carbon trading. Nonetheless, all these immense [178] opportunities have not yet been fully accredited and exploited, demanding strong international collaborations in supporting national certifiers and sustainable global Coffee initiatives for the development of the coffee sector and thus, maximize its decisive role in improving the livelihoods of the rural poor (Taye and Tesfaye, 2002). ...
... It also acts as a better source of nutrients, moisture, and aeration for fast germination, vigorous growth of roots, and shoot [33]. The present result in line with the research findings of [29,28,14,16] and [17] on coffee, peach, and korarima seedlings, respectively. Whereas, the retarded growth of cardamom seedlings on the sandy growth media might be associated with the poor sources of the media for nutrient and moisture for the growing seedlings. ...
... In general, the findings support the use of locally available organic resources instead of chemical fertilizer to boost coffee production for the country. The effect of organic input, on the other hand, can vary depending on nutrient composition, rate of decomposition, amount and method of application, and climatic conditions in the area [28]. NS = Non significant, * and ** =Significant at 5 and 1% probability level, respectively. ...
