Taraba State is one of the states in Nigeria that produce high quality timber. A study to determine the density and stands structure of Gangume Forest Reserve was carried out in Bali Local Government Area of Taraba State, Nigeria. Twenty hectare plots were lay out in the forest and each plot was re-demarcated into four equal sizes of 50m x 50m and one was randomly selected for enumeration. A total of 592 tree species were enumerated belonging to 17 families. The data were analyzed using frequency, percentage, density, basal area, diameter (dbh), and total height of the tree species. The result of the study revealed that the average density was 118 trees/ha, total basal area was 18.2918m2 with an average of 0.91459m2/ha and the diameter distribution revealed that majority (152) 26.0% of the trees falls into diameter class of 20-29cm, followed by 10-19cm (102) 17-2%, and 30-39cm (101) 17.0%. The density was more in the lower DBH from 10cm to 39cm accounting for a total of 380 (64.1) trees in the forest. Four stratum of tree species population structures were identified with the intermediate strata with the highest (201) 33.9% population of trees, followed by the co-dominant with (199) 33.6%, ground floor with (192) 32.4% and the dominant/emergent with only (10) 1.6% population of trees. There is high human activities in the forest despite the fact that the forest has good reproduction and ability of regeneration. The forest should be left undisturbed to regenerate naturally.

Potato late blight disease caused by Phytophthora infestans has become an economic disease in the world and particularly in potato growing regions of Cameroon. Four improved (Pamina, Sassy, Desiree, Diaman) and two local (Belo, Banso) cultivars of potatoes were screen in the field and screen house in Regional College of Agriculture and Catholic University laboratory for resistance to potatoes late blight disease (PLBD). These potatoes cultivars were planted on four ridges per plot in the field in randomized complete block design with three replicate. These cultivars were monitored for disease incidence and severity and data was collected. Potatoes cultivars were planted in a screen house and inoculated with spore suspension of P. infestans of 2.5×104 spores / ml of distilled water to evaluate the resistance of the various potatoes cultivars. Screen house and field screening showed significant varietal difference (P≤0.05) in sensitivity to the fungus. The improved and local cultivars of potatoes from field and screen house show varying levels of resistance to (PLBD). All the improved potatoes cultivars (Pamina, Sassy, Desiree and Diaman) were highly susceptible to (PLBD) compared to the local cultivars (Belo, Banso) and improved cultivar Desiree that were susceptible. The highest mean disease severity of (PLBD) of 5.0 % was recorded on cultivars, Pamina, Sassy and Diaman at 12 weeks after planting. Diaman recorded the highest mean area of (PLBD) growth of 11.45 m2 in the screen house experiment. The local and improved potatoes cultivars that were susceptible could be planted in the field by farmer to reduced disease incidence and severity and increase productivity of the crop.

Avocado (Persea americana Mill.) belongs to the family Lauraceae and it is an important crop to rural communities and economies in Kenya. Currently, avocado is grown in several agroecological zones mainly by small-scale growers (85%) who grow it for subsistence, local markets and export. About 70% of avocado is grown in Central and Eastern region of Kenya. Central region produces 40%, Eastern 28%, Western 13%, Rift Valley 10%, Nyanza 6%, Coast 2% and Nairobi County 1%. The main production areas are Muranga, Kiambu, Thika, Embu, Meru, Taita Hills and Kitale. The aim of this study was to assess the production constraints and contribution of avocado to food security and income in Mount Kenya region. The study population comprised of smallholder avocado farmers. Purposive sampling was done in selecting highest producing sub-counties of avocado in Nyeri, Muranga and Embu counties. Simple random sampling was used to select 40 smallholder farmers from each of the selected subcounties who participated in the survey. Data was collected using a structured questionnaire and analysed using SPSS computer package. Results indicated several constraints in the production of avocado including pests and diseases, lack of quality planting material, poor soils, lack of technical knowledge by avocado farmers and lack of well-structured marketing system. The study identified a gap in value addition of avocado in Kenya. It was also demonstrated that avocado contributes highly to household income and food security. The crop should therefore be accorded priority by policy makers and more research needs to be encouraged especially in the management of pests and diseases. Capacity building to avocado growers should be routinely carried out so as to avoid the many challenges that emanate from lack of technical knowledge. Intervention in value addition of avocado is an aspect that Kenyan county governments need to engage in by investing in cottage industries on avocado processing.
牛油果(Persea americana Mill.)属于樟科，是肯尼亚农村社区和经济的重要作物。目前，牛油果主要由小规模种植者(85%)在几个农业生态区种植，他们种植牛油果是为了维持生计、当地市场和出口。大约70%的鳄梨种植在肯尼亚中部和东部地区。中部地区产量40%，东部28%，西部13%，裂谷10%，尼扬扎6%，海岸2%，内罗毕县1%。主要产区有穆兰加、基安布、西卡、恩布、梅鲁、塔塔山和基塔莱。本研究的目的是评估牛油果在肯尼亚山区的生产限制和对粮食安全和收入的贡献。研究人群包括牛油果小农。选取牛油果产量最高的尼耶里县、穆兰加县和恩布县进行有目的抽样。采用简单随机抽样的方法，从每个选定的区县中抽取40名小农参与调查。采用结构化问卷收集数据，并使用SPSS软件包进行分析。结果表明，制约牛油果生产的因素包括病虫害、缺乏优质种植材料、土壤贫瘠、牛油果种植者缺乏技术知识和缺乏结构良好的营销体系。该研究确定了肯尼亚鳄梨附加值的差距。研究还表明，鳄梨对家庭收入和粮食安全的贡献很大。因此，决策者应优先考虑这种作物，需要鼓励进行更多的研究，特别是在病虫害管理方面。应定期开展牛油果种植者的能力建设，以避免因缺乏技术知识而产生的许多挑战。通过投资牛油果加工的家庭手工业，干预牛油果的增值是肯尼亚县政府需要参与的一个方面。

A field experiment was conducted at the students’ research farm Faculty of Agriculture, Nnamdi Azikiwe University Awka to determine the effect of Neem-based compost rate on soil physicochemical properties and growth responses of Amaranthus viridis in Awka. Three treatments were used and a control was set out to monitor the effects of the applied treatments. The design was laid out in a Randomized Complete Block Design (RCBD), with 4 replication each. Where beds with 0 t/ha received 0kg of the compost, 3.5 t/ha received 2.1 kg/m² of the compost, 7 t/ha received 4.2 kg/m² of the compost and 10.5 t/ha received 6.3 kg/m² of the compost. The experiment lasted for 6 months and plant data was collected before harvesting. The treatments were applied in an experimental plot of 2m by 2m. The result obtained was subjected to a statistical analysis of variance using GENstat and least significant difference (LSD) to compare the mean. The mean were separated at 5% level of significance. Generally the applied treatments improved soil fertility as there was a significant increase in Moisture content (MC), Field capacity (FC), Plant Available water (PAW), Permanent wilting point (PWP), Bulk density (BD), and Total porosity (TP) of the soil. Also, potential hydrogen ion (pH), Available phosphorus (Av. P), Nitrogen (T.N), Organic carbon (OC), Calcium (Ca), Magnesium (Mg), Potassium (K), Sodium (Na), Exchangeable Acidity (EA), Effective Cation Exchange Capacity (ECEC), Base Saturation (BS) and exchangeable aluminum (Al3+) were all significantly differed. On the effects of the treatments on growth parameters, T3 (7 t/ha) gave the highest plant height and number of leaves with mean value of 25.8", and 30.9" respectively. The control gave the highest mean leaf width 3.43".

Sorghum is a staple food in Mali, yet grain yields are low and do not contain high lysine, threonine, iron and zinc content. Drought is the most significant cause of crop yield loss, especially in water limited areas where most of the world’s poorest farmers live. Development of drought tolerant bio-fortified sorghum hybrids will enhance food production and the livelihood of farmers in these areas. To assess the adaptation, yield potential, and to identify the traits contributing directly and indirectly to drought resilience, a study was conducted in two locations. Thus, a total of 49 F1 hybrids were developed and used in this study along with three commercial hybrids. Ten (10) bio fortified hybrids were identified with grain yield ranging from 3774 to 5068 kg ha-1 with an average heading date of 74-83 days. The new bio-fortified sorghum hybrids in this study yielded three times as much as the local varieties, which yielded 1 to 1.5 tons. The index of varietal sensitivity varied 253.43 to 81.12 %. For drought resilience, a significant correlation was identified with index of varietal sensitivity through mibrid, stay green and leaf senescence. A positive and negative correlation among grain yield, stay green and mibrid were observed. This study identified bio fortified sorghum hybrids with high grain yield and tolerant to drought stresses. These ten hybrids are worthy to be utilized in participatory trials for their registration in the seed catalog.

The study generally identified and analyzedthe ecological status and socio-economic status of coastal communities of Barangay Tapel, Gonzaga, Cagayan, and also their dependency on the floral and faunal resources of water. The studycarried out interviews based on questionnaires and useddescriptive survey research design. The results of the study revealed that most of the respondents have a low level of education with fishing as the main source of income. Fishing as a source of income tells that BarangayTapel is a coastal community. Fishing activities are alsodone to the estuary where mangrove trees thrive. Most of the respondents said that the benefits derived from the coastal environments are recreation/relaxation, bathing/swimming, andtransportand navigation. However, due to natural and anthropogenic disturbances, today, benefits derived from the coastal area are very limited since there are changes observed in coastal resources specifically on the fishing ground location andvolume of catch. This generally implies that full understanding of socio-economic characteristics, coastal resource useand perception, and participation of the community plays animportant rolein the coastal resource restoration and management plans. Also, thisdatabase helps to understand the underlying causes of degradation and interventions needed in this community.

Inbreeding within sheep populations is a relatively understudied area due to limited pedigree information. This study assessed the level of inbreeding within a Charollais sheep population. Data were obtained from35,220 Charollais lambs between the years2000 to 2018 from performance-recorded flocks in the UK. Differences among flocks, study years, lamb eight-week body weight categories and if embryo transfer lambs were assessed. Mean inbreeding value for Charollaislambswas2.8% (s.e. ± 0.1), with a range of 0% to 31%. While the proportion of lambs with an inbreeding value of >7% has been relatively stable at 0.1 or less since 2006, the general trend is an increasing mean inbreeding coefficient for the population in recent years. After adjusting lamb inbreeding coefficient for fixed and random effects, the average inbreeding coefficient was found to be lower for lambs in the heavier eight-week body weight category (>32kg), for certain flocks (mean ranged from 0.4% to 14.6%), and for embryo transfer lambs. Monitoring of inbreeding and approaches used for genetic selection in flocks can help minimise poor lamb performance(i.e. potentially lower growth and body weight) associated with inbreeding.

Monitoring of inbreeding and approaches used for genetic selection in flocks can help minimise poor lamb performance(i.e. potentially lower growth and body weight) associated with inbreeding.","PeriodicalId":364314,"journal":{"name":"International Journal of Agriculture, Environment and Bioresearch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114221111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In northern Côte d'Ivoire, fishing is mainly practiced in agro-pastoral Dam Lakes. Previous studies on some of them indicated the possibility to increase their exploited production. This study was conducted from October 2018 to September 2019 on the Solomougou Dam Lake. Its objectives are to study the intensity of fishing activity and the rate of exploitation of this fishery. It appears that fishing is practiced throughout the year on this lake. However, 54.54% of fishermen stay there less than 6 months, also exploiting other fisheries in the region. Less frequented from August to October, its colonization gradually increases from November to reach the peak in March. Fishing gears are used seasonally. In fact, traps and gillnets are less used respectively during low water and flood periods of the Dam Lake. Sparrow hawks, less used by fishermen, are however used throughout the year while the use of longlines, bamboo traps and seine nets is limited to a few months. In terms of exploitation of the fishery, a density of 6.6 fishermen per km2 would be observed in a situation of full exploitation indicating a state of overexploitation of the fishery. However, taking into account fluctuations of fishermen’s number per month, their densities ranged between 0.8 and 2.6 fishermen per km2 from July to December, indicative of normal exploitation of the fishery and between 3.2 and 4.2 fishermen per km2 outside this period, a little above the recommended standards.

Arabica coffee is one of the main crop in Aie Dingin, Lembah Gumanti. However, production of arabica coffee in Aie Dingin is still low. Thus, this is important for analysis and assessment soil quality which have related to production of arabica coffee. The present study was conducted in Aie Dingin, Lembah Gumanti. The composite sample were collected from 0-20 cm, 20-40 cm, and 40-60 cm of soil depth in 12 location. The analysis of soil included: soil pH, cation exchange capacity (CEC), organic matter (OM), and base saturation (BS). The results showed that the most area in acidity, cation exchange capacity (CEC), organic matter (OM), and base saturation (BS) are dominant very low. For improving soil quality, we suggestion adding lime and fertilzer also growing protecting crops for prevent high rainwater directly to land field so that leaching was not occurred.
