Survey on the Severity of Xanthomonas Axonopodis PV Malvacearum and its Management in Adamawa State, Nigeria (Published)

Prevalence survey on bacterial blight disease of cotton were carried out in some cotton growing locations in Adamawa State in 2018 to determine the severity of the disease in the study areas and the best combinations of cotton genotypes and plant extracts in the management of the disease. Results of the survey revealed the presence of the disease with variable percentage severities with Yola South recording the highest severity of 67.03%, followed by Guyuk (58.24%) while the least severity of 35.97% was recorded in Lamurde Local Government Area respectively. Results further showed that the combination of SAMCOT 8 cotton variety with Allium sativum as plant extract (50%) gave the best control of the disease during the study. This study has revealed the presence of the diseases in these locations with varying levels of severities. Further studies of the disease and other diseases in other locations needs to be carried out so as to determine the most effective management strategy.

Review On Land Degradation and Its Management (Published)

Land is the essential component which provides us food, shelter, and fiber. It is non-renewable resource which is degrading day to day. The present review focuses on effect of land degradation on agriculture and environment; and how we can manage our lands from further degradation. Agriculture is an important sector of economy and plays a significant role like GDP share, foreign exchange earnings, and employment. Land degradation is an environmental process in which biological, economical, and quality of land is lost due to alteration in chemical, physical, and biological properties. Factors like climatic, natural, and anthropogenic deteriorate the quality of land and degraded it for agricultural use. Agriculture sector is directly linked with land while most of the agriculture land is degraded by some factors. The most frequent causes of degradation are poor farming practices, inappropriate irrigation, overgrazing, urban sprawl, commercial development, and land clearance.  Due to rapid changes in climatic conditions, deforestation, desertification, erosion, salinization, water logging, and organic matter depletion lead to land degradation. For restoration of land, it is important to minimize these activities and properly managed all factors. We can manage our land by ground covers, alternate fuels, timber replantation, and dams and by making the policies. Improvement and reclamation of degraded lands the domestic structure must be integrated in all related areas which gives direction for asset in sustainable land management and stimulating community response towards sustainable land management. Furthermore, organic agriculture may be an alternative to save our land from degradation.

White Mango Scale (Aulacaspis tubercularis) Management approaches: A Review (Published)

There are different species of insects and diseases that contribute to low yield of mango tree throughout its stages of development. This review was intended to collect research works on white mango scale with special focus on research works done in Ethiopia. Different findings of research works on the insect were carefully studied. The white mango scale insect, Aulacaspis tubercularis (Hemiptera: Diaspididae) is a recent threat to mango production in Ethiopia which was introduced the first time in 2010 in western part of the country. It has spread to all mango producing areas of the country within a short period of time reducing the production and quality of mangos. Control measures taken against the white mango scale include use of chemical insecticides, quarantine, cultural practices, biological control using parasitoids and predators and integrated pest management. Quarantining the insect is the management method recommended in many cases. Generally, the current reports revealed that mango production in Ethiopia will be under serious threat which can even destroy total mango production in the future.

Effect of Management Factor on Stochastic Frontier Production of Organic Rice Farming in Indonesia (Published)

The main problem in this study is the effect of management factor on stochastic frontier production of organic rice farming that emphasized production efficiency. The aim of this research was to analyze the role of managerial ability of farmers in organic rice farming production. This study was conducted on 216 organic rice farmers as a sample during two planting seasons with purposive sampling method. The sample was consisted of two farmer groups, i.e. Pangudi Bogo and Pangudi Raharjo in Dlingo Village, Mojosongo District, Boyolali Regency, Central Java Province, Indonesia. This research used stochastic frontier production function approach with cross section data and estimated with maximum likelihood estimation. The result showed that average value of production efficiency is 0.5928 and the most dominant variable in determining the technical inefficiency of organic rice farming was variable of farming system management.
