ABSTRACT
Cotton breeding programs are mainly focus on improving fiber although the oil extracted from cotton seeds is the fifth vegetable oil consumed in the world due to its good quality. The purpose of this study was to evaluate six cultivars of Gossypium hirsutum regarding their oil content on four locations in the northern Cameroon during two consecutive seasons, in order to select stable genotypes for high oil content. In each location, the experimental design was a completely randomized block with three replications. The determination of the oil content of the cottonseeds was done by the Soxhlet method. Genotype x environment interaction (GEI) and analysis of stability of the varieties were determined by different methods using GEST 98 package. The variability among genotypes was high across environments for oil content (20.34% in Berem to 26.08% in Kourgui). The top ranked lines for oil were Irma Q302 (26.61%) and Irma A2249 (26.40%). This showed that there is genetic and environmental variability that can be exploited for the selection of genotypes at each site. The broad-sense heritability for oil content varied from 0.79 (Pitoa) to 0.83 (Berem) and expected genetic gain ranged from 14% to 23% with an overall average of 19%. Genotypes, environment and GEI effects were all significant and accounted respectively 35.65%, 43.41% and 20.93% of the total variation. Stability analysis identified high-yielding genotype Irma Q302 as specifically adapted to favourable environments of Kourgui and Pitoa.

ABSTRACT
This paper presents a succession dispute in the Sabga Lamidate in Cameroon in 2007 between Abdouliy Mamouda and Yerima Adamu Buba, both princes of the Lamidate and argues that the dispute emanated from manipulation by interest groups and the violation of the succession tradition of the Lamidate by government authorities. For about nine decades since creation in 1925, the Sabga Lamidate has experienced a relative and uninterrupted peace until 2007 when this succession dispute provoked uproar and drew attention both from within and without the North West Region of Cameroon. On Monday 20 August 2007, the then Senior Divisional officer (SDO) for Mezam, Jules Marcelline Ndjanga, Alhadji Baba Danpullo and the Lamido of Banyo, Mohaman Gabdo Yaya accompanied by 200 armed mixed gendarmes and police officers, moved into the Sabga Lamidate and performed an enthronement rite placing Abdoulaiy Mamouda as the designatory successor of the late Lamido Adamou Sabga. This action provoked open opposition resulting in a succession dispute in the Lamidate as Adamu Buba, a contender and choice of the people elected democratically by kingmakers and according to tradition was denied the throne. In order to put our facts in a logical order and to ensure the flow of these narratives, we employed a triangulation of both qualitative and quantitative research methodologies, besides knowledge on participatory observation. We also relied more on live video images provided by the MBOSCUDA (Mbororo Social and Cultural Development Association) office in Bamenda including Newspaper reports on the issue at the time. The paper reveals that: The dispute emanated from the determination of Danpullo to grab the Sabga grazing land, The enthronement of Mamouda was contrary to the succession tradition of the Sabga Lamidate and against the will of its kingmakers and their kith and kin; Danpullo and the fon of Kedjom-Ketingo were at the fore front of the manipulation; the Cameroon Government tolerance paved ...

ABSTRACT
The study examined the role of local leaders in community development decision making in Dutse Local Government area of Jigawa State, Nigeria. A multistage (4) stage sampling procedure was employed in selecting 120 respondents for the study. Mean age and household size are 53 years and 10 persons. Majority (97.5%) were males, married (95.8%) with secondary education (57.6%). Only about 1/3 (33.3%) had tertiary education while 8.3% had primary education. Significant proportion (91.7%) claimed to have travelled within and outside the study area. The type of leadership existing and acting were; traditional and household leaderships (x ̅=1.011), religious and cooperative leaderships (x ̅=1.383). Areas of roles and influences of the leaders mostly were in; support for art and culture, mobilization, control of market activities, advice on religious matters and chieftaincy matters (x ̅=1.047). Participation in community activities were in the areas of; conflict resolution, chieftaincy affairs, religious matters, support for community development projects, mouth piece of the people, mobilization, political/LGA advice, cultural matter and council matters (x ̅=1.071). Major constraints to participation were; cultural belief and heterophili (x ̅=1.250), mindset of the people and poor socialization (x ̅=1.199) and exclusion from government development projects (x ̅=1.009) respectively. The Pearson Correlation analysis showed positive relationship between participation and degree of Cosmo-politeness, age, educational level respectively. It was recommended that local leaders should be engaged more in community development activities because they serve a catalytic function to the people. Community intervention or development programmes must be geared towards the socio-cultural structure of the people. Respondents should also be encouraged to visit other place in order to foster understanding of cultural differences and diversity, socialization and modernization emanating from ....

ABSTRACT
Agricultural land accessibility and use in Burundi has been reviewed and analyzed in this study. SWOT and SOR analysis have been used to examine its strengths, weaknesses, opportunities and threats and some strategies that can lead to sustainable agriculture have been determined. It has been observed that Burundi has a serious problem with agricultural land atomicity. More than 40% of agricultural households cultivate plots less than 0.25 ha. Kayanza and Ngozi are most densely populated provinces. 44% of the agricultural land is on sloping hills and a total of 145.3 tons/ha of arable land is lost every year. However, thanks to the efforts of land development projects, arable land has increased and reached 79.17% of total area of the country in 2018. Unfortunately, it has been shown that the growth rate of agricultural production over the last decade was lower (2%) than the population growth rate (2.6%-3%). It is desirable to implement a land consolidation policy, especially in densely populated areas. For eroded soils, it is ideal to strengthen anti-erosion practices to protect soils and save water. Government of Burundi and NGOs should support agricultural sector by disseminating methods and techniques that will ensure sustainable management of agricultural land.

ABSTRACT
This study was conducted to examine the impact of changes in annual mean temperature, annual mean precipitation, carbon footprint, ecological footprint, and area harvested on cereal crop production in East Africa. The study was conducted in a panel cointegration framework using annual time series from 1980 to 2018 for five East African countries i.e., Ethiopia, Kenya, Rwanda, Tanzania, and Uganda. Unit root tests were performed using LLC, IPS, ADF-Fisher, and PP-Fisher tests, while panel co-integration tests were performed using Pedroni residual, Kao residual, and Johansen Fisher panel co-integration tests. Long-run coefficients were estimated using the Pooled Mean Group/Autoregressive Distributed Lag, Panel Fully-modified OLS, and Panel Dynamic OLS models. Empirical findings from the three models revealed that increases in annual mean temperature have adverse effects on cereal crop production, while increases in annual mean precipitation, carbon footprint, ecological footprint, and area harvested have positive effects on cereal crop production in East Africa. Based on these findings, it can be suggested that prioritization of climate change adaptation strategies in the region such as the development of drought and heat-resistant crop varieties, changing in planting dates, and investment in irrigation technologies to boost cereal crops productivity could play a role in minimizing the adverse effects of changes in climate factors.

ABSTRACT
The objective of this seminar is to present the levels of metals in commercially available imported and Ethiopian rice. The levels of thirteen metals (Ca, Mg, K, Na, Fe, Mn, Zn, Cu, Co, Ni, Cr, Cd and Pb) were determined in six varieties of raw rice collected from Addis Ababa supermarket, Fogera town and Amahara Regional Agricultural Research Institute and in one selected cooked rice by flame atomic absorption spectrometry after digesting the powdered rice samples with HNO3, HClO4 and H2O2 mixture. The levels of metals found in the imported and Ethiopian rice, respectively, were in the ranges (mg/kg): Ca 75.8- 630, 205-427; Mg 90.6-150, 99.5-2250; K 1680-2150, 1100-3020; Na 70.6-78.6, 26.7-80.9; Fe 48.9-117, 41.3-113; Mn 4.1-15.5, 3.7-16.6; Zn 16.4-25.7, 15.6-140; Cu 2.7-4.9, 3.3-15; Co 12.6- 14.6, 8.8-10.4; Ni 2.5-75.1, 41.5-69.7; Cr 2.2-3.12, 2.32-4.82; Cd Comparison between levels of metals in the imported and Ethiopian rice showed significant differences for most of the metals. The results indicated that Ethiopian rice is comparatively rich in essential metals than imported one. A statistical analysis of variance (ANOVA) at 95% confidence level for metal determination indicated significant difference between the means of each variety of samples. Comparison between levels of metals in cooked and raw rice showed that the difference in the level is not significant.

ABSTRACT
This work's main objective was to evaluate the effect of certain strains of arbuscular mycorrhizal fungi on acid phosphatase activity during growth. The treatments applied were, control, Glomus intraradices, Acaulospora tuberculata, Gigaspora margarita, Glomus sp., and the mixture of these four AMF strains. Their effect on the growth of vitroplants was evaluated on days 60, 120, and 180 after inoculation. Mycorrhizal status following treatments and acid phosphatase activity were assessed. The minitubers obtained were subjected to a preservation and germination test. The results showed that the maximum growth peak of X. sagittifolium plants was obtained on day 120 for all treatments. The mixture of the four strains of AMF had more influence on the growth parameters with values of 18.40±0.54 Cm and 42.34±16.67 Cm2, respectively for the average number of roots and leaf area. Mycorrhization did not significantly influence the mean number of leaves and mean plant height. Mycorrhizal structures were observed in all mycorrhizal treatments applied. The frequency of mycorrhization was very high in plants inoculated with Glomus sp. The evaluation of the phosphatase activity shows a significant activity at the level of the leaves with a peak of activity in the plants inoculated with Glomus sp. (47.72±0.07 µM/min/g of FW). Compared to the control, the number of minitubers produced was two to three times higher. The best tuberization percentage (80%) was obtained in plants inoculated with a mixture of AMF strains. The temperature of 7~10°C allowed the preservation of 50% of the germination capacity of the minitubers after two months. Based on the obtained results, it was concluded that fertilization with AMF is beneficial for the stimulation of minitubers production.
