Abstract: Homegarden agroforestry is a multi-purpose agroforestry approach used by rural farmers in and around their houses to diversify their livelihoods and stabilize their food security. Fifty three plant species, disperse into 23 families, were recorded in the study area from highland, lowland and midland Homegarden agroforestry. The Myrtaceae family is the dominant with 6 species, subsequently Fabaceae and Euphorbiaceae family with 5 species. From this finding result, midland agro ecology has a at great height number of plant species per home garden than other agro ecologies. Research design was used to gather data focused on smallholder homegarden agroforestry. It is acclimated describe homegarden agroforestry composition and diversity. One-way ANOVA was applyed to analyze data to compare as well as identify statistically difference between three agro-ecologies. The Shannon diversity index revealed that the midland woody species diversity index (H'=2.94) was higher than the highland (H'=2.91) and lowland (H’=2.89). According to Sorensen's similarity coefficient out of the three home gardens, midland and highland have agreat number of species compositions in common (76%). A relatively low similarity was perceived between highland and lowland. Awareness is required by concerned individuals to keep the multispecies farming system that contributes more diversity of native plant species of this system.

Abstract: The high savannahs of Guinea are highly diverse and play an important role in maintaining biodiversity. However, they are periodically subjected to various pressures that sometimes have a negative impact on the productivity of these ecosystems. The aim of this study was to assess the impact of logging and bush fires on the regeneration dynamics of plant species in the high savannahs of Adamaoua, Cameroon. To this end, 18 square plots, each measuring 10 metres on a side, were delimited in both a shrub and tree savannah, following a randomised block experimental set-up with the different anthropogenic actions applied as treatments (logging without fire, logging with fire and control). During the two years of experimentation, the rate of erosion and biological degradation were assessed by simple observation, as well as some anthropisation indices. The results showed that 100% of the sites where wood was cut without fire (CSF) and cut with fire (CAF) had a flat surface in the tree savannas, unlike the shrub savannas where only the CAF and the control site (T) were all 66.67% flat. In the shrub savannah, zero erosion had the same rate (66.67%) for the three different treatments. However, it was 100% for the CSF treatments, 66.67% for the control sites and 33.33% for the CAF sites in the shrub savannas. The fine structure is represented in all treatments; it is 100% in the CAF treed savannah treatments and 66.67% in the CSF shrub and tree savannah treatments. Ground cover by vegetation is very high, at 100% in the treed savannah, 66.67% in the CSF and 33.33% in the CAF and T treatments in the shrub savannah. Regardless of the type of savannah, grazing is the most common activity, with a rate of 66.67%. The presence of termite mounds (33.33%), anthills (33.33%) and wood cuttings (33.33%) is moderately represented. The rate of soil degradation by livestock is 66.67% at the CSF and CAF sites, but 100% at the T site. In the wooded savannah, this rate is 100% in the CSF and CAF sites, but T is only impacted by livestock at a rate of 66.67%. There has been a remarkable increase in the area of shrub savannah (129411 ha), and a 14.56% reduction in the area of gallery forests between 2007 and 2017.

Abstract: Adaptation performance field experiment on irrigated cotton cultivars for high productivity for large scale production and economic advantage were conducted in RCB Design by replicating four times to identify the high yielding with high quality cotton cultivar using surface irrigation at Tendaho sugar estate. All collected data were analyzed using GenStat 17th Edition software and mean comparisons among treatment means were made by LSD (5%). Cotton quality comparisons were also done based on the national quality measurement standards and the cotton quality laboratory analysis was done in Cotton Central accredited laboratory of Ethiopia under Ethiopian Textile Development and Research Institute. Significant difference (p<0.05) among the tested cotton cultivars were reported for stand count (SC), number of unopened balls per plant and percent of 65 percent opened ball. However, there were no significant variability for total cotton yield (Y (kg/ha), lint yield and moisture adjusted yield (MoiAd_Y_Qt_Ha) at (p<0.05) significance level. From the candidate cultivars, woyito and worer shown first and second high cotton productivity with 32 and 31.1 qt/ha cotton yield respectively followed by Stam-9-A as third with 30 qt/ha. In the other case, Stam-9-A and Delta ranked first for the major cotton quality standard measures. From this, it can be concluded that candidate genotype Stam-9-A which is third in productivity and first in cotton quality could have better advantage for the Estate. Therefore, based on the current adaptation trail result candidate cultivar Stam-9-A is recommended for commercial production in the study farm area.
