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.","PeriodicalId":364314,"journal":{"name":"International Journal of Agriculture, Environment and Bioresearch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135505204","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}

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.

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.","PeriodicalId":364314,"journal":{"name":"International Journal of Agriculture, Environment and Bioresearch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135506537","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}

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.","PeriodicalId":364314,"journal":{"name":"International Journal of Agriculture, Environment and Bioresearch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135505931","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}

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.

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.

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.","PeriodicalId":364314,"journal":{"name":"International Journal of Agriculture, Environment and Bioresearch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115146991","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}
