Forty (40) seedlings were randomly selected from the germinated seedlings in the nursery and arrayed under four different treatments (0, 20, 40 and 60% light intensity). The amount of light being received by each of the seedlings was regulated, using constructed wooden box covered with wire gauze (1 mm in size) and measured with photometer. The results on seedlings germination under different light intensity revealed that, the highest mean height (29.2±1.94 cm) was observed in seedlings covered with 60% wire gauze, while the least mean height (27.0±1.24 cm) was observed in the seedlings placed under control treatment (0% wire gauze). Also the highest mean seedlings girth (2.69 ± 0.15 mm) was observed in seedlings not restricted with light intensity (0% wire gauze), while, the least mean girth (2.27±0.08 mm) was found in seedlings restricted with 60% light intensity. The average number of leaves in the four treatments ranges between 6 and 7. The result on analysis of variance (ANOVA) conducted shows a significant effects (P 0.05).

This study sought to evaluate the seed physiological quality of two cultivars of African eggplant subjected to various durations of natural fermentation and different drying methods. In the first study, fruits were fermented for 0, 6, 12, 24 and 48 h before seed extraction. In the second experiment, seeds were extracted and subjected to sun/24 h; shade/24 h; shade/48 h; desiccant (silica gel)/24 h; shade/24 h + 30 °C oven (24 h); 30°C/24 h; 35 °C/24 h; 45 °C/24 h; 50°C/24 h and 60°C/24 h for drying. The seed quality evaluation were seed moisture content, seed dry weight, first count, seed germination and accelerated aging. The results suggest that African eggplant seeds do not require natural fermentation during extraction for enhanced seed germination. All drying methods were able to reduce seed moisture content to an ideal level for storage and maintained seed physiological quality.

Degraded land rehabilitation in dryland is a challenging task due to moisture limitation. This study was conducted to evaluate the effects of soil and water conservation structures on growth of planted tree and rehabilitation of indigenous plant species in West Guji Zone, Dugda Dawa District. Four multipurpose tree species (MPTs) namely Faidherbia albida, Melia azedarach, Moringa stenopetala, and Sesbania sesban were planted in four soil and moisture conservation structures (soil level bund, half-moon, trench and normal pit). Data of survival rate, height and diameter growth of planted tree species and, diversity and species richness of indigenous plant species were collected. The survival rate of all planted MPTs species were declining along the study years; however, the survival rate was better under soil level bund and half-moon. Under control treatments, all planted MPTs died at the end of the study period. The height and stem diameter of F. albida, M. azedarach and M. stenopetala were best in soil level bund and half-moon and followed by the trench. Whereas, the growth performance of Sesbania sesban was not significantly different among the three moisture conservation structures. Furthermore, soil moisture conservation structures significantly increased the indigenous plant species regeneration after the intervention. The mean indigenous plant species diversity and richness were significantly highest in half-moon and soil level bund followed by trench and, lowest in Control (normal pit).

An inexpensive cell phone camera can be used. The tree height is calculated by using a ruler to measure the tree height and reference height on the photo. Previously, this method was thought to be accurate only if the distance to the camera was many times the tree height. However, if the cell phone is held vertically, at a right angle to level, this eliminates the optical foreshortening in viewing a tall tree. The photo method produces a very accurate estimate of tree height. By using this method in a test experiment, the photo method had an inaccuracy of less than 1%. The most common measurement methods used by professionals are the tangent and sine methods, which use clinometers and laser rangefinders. These methods require measuring the distance to the tree, the elevation of the instrument above the base of the tree, and the angle to the top of the tree. The photo method is easier and potentially more accurate than the tangent and sine methods.

Some actors circumvented some links to increase revenue. Quality of trees and sawn timber were key determinants of monetary value transacted along the chain. Inadequate farmers’ skills in tree silviculture, valuation and cumbersome procedures in obtaining Government permits were also mentioned as major challenges, while timber sawyers lacked efficient sawing technology, consequently lowering income along the entire value chain.
