A fundamental aspect in the management of secondary forests of this species is the need to concentrate growth on the dominant trees, since the achievement of large-sized individuals is essential for supplying the wood industry. Within the framework of a project aimed at designing management tools that make it possible to make high forest production compatible with livestock. To this effect, preliminary results of the response of the forest mass as well as of the remaining individuals are presented against three intensities of selective thinning. The objective of the work is to have basic information that allows establishing sustainable management guidelines in secondary forests, in its initial stages for the provision of quality wood for forestry-industry with forestry-livestock production schemes.","PeriodicalId":176249,"journal":{"name":"Forestry Research and Engineering: International Journal","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128633707","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}

Since construction of medium to modern irrigated agriculture is expensive, matching crop requirement with resources available through land suitability evaluation is necessary to improve production and productivity in the area. Such important study however,ha.s not been undertaken in Kilosa kwa Mpepo traditional irrigation scheme proposed for modernization. This study, evaluates the land suitability of Kilosa kwa Mpepo traditional irrigation scheme for rice (Oryza sativa L.) and maize (Zea mays L.) cropping systems using FAO maximum limitation method. After matching land qualities with land use requirements, results indicated that soil wetness, soil physical characteristics, and soil fertility status were the major limiting factors affecting land quality within the proposed irrigation scheme. Results also showed that of the total area surveyed (i.e. 1,117 Ha) 25% was rated as highly suitable (S1), 37% as moderately suitable (S2) and 37% as marginally suitable (S3) for irrigated rice based cropping systems. However, after controlling floods the highly suitable (S1) to marginally suitable (S3) land observed was to a large extent related to soil physical property, leading to inadequate capacity to retain nutrients. Similarly, results of land suitability for irrigated maize based cropping systems indicated that of the total study area, 37% was rated as highly suitable (S1) and 63% as moderately suitable (S2). The moderately suitable land in the surveyed area was related to soil physical property and poor soil fertility status (i.e. texture and low pH). Taken together, these data suggest that well-designed irrigation infrastructures along with flood protection band and drainage structures may control and or reduce the incidence of floods and waterlogging conditions in the study area. Long-term fertility management requires consideration of use of organic materials such as manure and compost. Such programs need to maximize use efficiency and minimize environmental losses. Implementation of the proposed approach to optimizing land management will reverse the suitability of land from marginally suitable to highly suitable land thus delivering a range of socio-economic and agro-environmental benefits to the farmers in Kilosa kwa Mpepo village in Malinyi District","PeriodicalId":176249,"journal":{"name":"Forestry Research and Engineering: International Journal","volume":" 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141222044","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}

On the other hand, the absence of soil conservation practice can lead to accelerating soil erosion and affect the components of physical soil conditions significantly.7 Soil and water conservation practices have the ability to overcome the problem of soil erosion followed by improvement in soil physical properties. Wise use of soil conservation practices that are the decisive tool to maintain the productive potential of the soil help to decreasing the exposure of soil to erosion. Conservation practices can address both the processes of soil erosion and possible solutions to conserve the soil in a sustainable way. The improvement is in soil organic matter content, soil structure and its aggregate stability, water holding capacity, soil bulk density, soil porosity, and its workability.8 Similarly, low soil porosity, gravimetric soil moisture content, clay and silt proportion was revealed in the cultivated land without soil bund as compared with non–conserved land and reversely highest soil bulk density and sand fraction.9 Soil erosion has a great negative effect on the change of soil physical properties including soil structure, soil texture, soil moisture content, and soil bulk density in a long period of time.","PeriodicalId":176249,"journal":{"name":"Forestry Research and Engineering: International Journal","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126052348","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}

Contemporary evaluations say that Liberia’s forest is dwindling, but Liberia still has one of the largest remnants of pristine forests in the world. The Amazon region in Brazil, South America, and the Congo Basin in Central Africa, can boast of larger forests, but the Liberian forest is large and a real economic resource for both agriculture and forestry. Response to the demand for timber, non–timber forest products, mining, and agricultural products is deforestation and land clearing, both of which are taking a negative toll on forest and agricultural lands. Land clearing, including the complete removal of large and otherwise robust trees, is typically imperative. A major focus of small farmers consequently involves tree felling, land clearing, and debris removal by burning. Moreover, improper extraction of forest trees, with other misuse of agriculture and forestry lands, is having very negative effects, including increasing erosion, poor drainage, low soil fertility, and the resultant poor land productivity.1","PeriodicalId":176249,"journal":{"name":"Forestry Research and Engineering: International Journal","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133123180","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}

Therefore, partitioning of overall variance due to genetic and non–genetic causes becomes necessary for effective breeding programme. The genotypic coefficient of variation estimates the heritable variability, whereas phenotypic component measures the role of environment on the genotype. High phenotypic coefficient of variation and low genotypic coefficient of variation for a character indicated high influence of environment in its expression. The phenomenon of transmission of characters from parents to offspring is usually measured in terms of heritability. Therefore the estimates of heritability and genetic advance would help to formulate a sound breeding programme.
