Globally, fourteen types of Moringa species are discovered. Among these species Moringaoleifera and Moringastenopetala potentially use for nutritional purpose, medicinal and feed values. In addition to these, Moringa leaf juice is being use in the form of a foliar spray that causes the plants to be stronger, more resistant to pests and disease and enhances plant growth. Plants treated with Moringa juice spray produce more and larger fruit and consequently have higher yield. The study conducted at "Kewet" district, Shewa Robit site with the objective of evaluating the contribution of Moringa leaf juice on grain yield and biomass production of sorghum. The result indicated that there was no significant difference observed among treatments on grain yield. However, foliar spray of Moringaoleifera with fertilizer and Moringastenopetala with fertilizer was obtained 25% and 34% of grain yield advantage as compare to only chemical fertilization application. Hence, at Shewarobit condition, foliar spray of Moringa leaf juice is not recommended for sorghum grain yield production. However further study is required across different soil type and agro climatology.
Background: Jatropha curcas (L.) is drought resistant large shrub or small tree. It belongs to the genus Jatropha and the family Euphorbiaceae. It is native to tropical America, but now found abundantly in many tropical and sub-tropical regions. Jatropha curcas (L.) is one of the important species that bear seed containing oil with a potential use as biodiesel. The objective of this research is to estimate the seed oil content and variability for some tree morphological traits of Jatropha curcas population in Ethiopia. Methodology: Fourteen Jatropha curcas populations were collected at different parts of Ethiopia. Sixteen plants per plot were planted at Shewarobit site in randomized complete block design with three replications. Data on survival rate, number of branches, seed yields and growth parameters were collected from those plants. Results: The result showed that a survival rate of 85-100%, average root collar diameter was 11cm and plant height of 235 cm were recorded at the age of 39 months after planting. Different traits of Jatropha curcas indicated statistically no significant difference (p>0.05). However, slightly higher seed and oil yield (k.g/ha/year) 3016.0 & 111169.8, 2711.3 & 91235.25 were found from Chefa and R1-009 seed sources, respectively. Conclusions: Even if, there was no significant difference observed among seed sources. Hence, Chefa and R1-009 collections have slightly greater yield both in seed and oil yields. So they should be chosen for future seed sources to produce crude oil due to their relative higher seed number and oil yield.
BackgroundTropical agroforestry systems can contribute incredible benefit for carbon sequestration and plant diversity. This system is one of the common practices in the Central part of Ethiopia. This is because of source of the multifunctional ecosystem services, such as food, feed, biodiversity conservation and carbon storage potential. MethodologyThis study was carried out to assess the influence of land size on floristic diversity, richness and biomass carbon stock. The homegardens were classified into small (<0.06 ha), medium (0.06–0.1 ha) and large (>0.1 ha). Biomass of the homegarden was computed using allometric equations.ResultsA total of 39 woody species, belonging to 24 families were recorded in all the study homegardens. Tree density 625.8 tree ha-1 and basal area 17.3 m2ha-1 were highest for small-size HGs. However, large homegarden had more species richness (Margalef Index) per garden (12.4) compared to medium and small size homegarden. Mean biomass carbon ranged from 9 to 89.3 ton ha-1. Mean biomass carbon stock per unit area was higher in small homegarden (49.3 ton ha-1) compared to medium (38.4 ton ha-1) and large (35 ton ha-1). ConclusionsThis result implies that homegarden can serve as both for carbon sequestration and conservation of woody species diversity. However, a specific homegarden management plan is necessary to improve the carbon storage and species diversification to the respective area. The results provide a catalyst the implication of the future potential of homegarden management in carbon storage thereby for climate change adaptation and mitigation purpose.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
