Abstract: This study was examined the nutrient content of compost prepared by farmers for soil fertility improvement and crop production. Heavy metal concentration in the compost was also investigated. The specific objectives were to asses and evaluate nutrient contents of farmers practiced composts prepared from diversified material sources and to make data base for composting processes. A total 213 samples were collected from Bedele, Gechi and Dabo district by random sampling methods from a representative sites. The pH, moisture content, OC, TN, C:N ratio, exchangeable Ca and Mg, Available P, EC, Mn, Fe, Cu and Znwere analyzed according to a standard laboratory procedure. An average OC and OM content of farmer practiced composts were 10.1, 13.9 and 12.1% and 18.9, 23.96 and 20.86% in Bedele, Gechi and Dabo Hana respectively. An average Moisture content of compost prepared in the study areas were 7.2, 7.6 and 6.2 for Bedele, Gechi and Dabo Hana respectively. Moisture content of compost prepared in these three districts were below the standard range. This may be caused due to the problem of watering during compost preparation. An average electric conductivity of composts were 1.5, 1.1 and 1.2 in Bedele, Gechi and Dabo Hana disticts respectively. The majority of the macro and micronutrients were analyzed for compost collected from Bedele, Gechi and Dabo Hana district were below the recommended range. This is due to unbalanced substrate during compost preparation especially absence of legume materials or residue from mixing materials.

Abstract: Tea is economically important export commodity for Ethiopia Predicting the physical land suitability of tea is vital to avoid a sightless expansion of tea plantations and significant to recognize the potential suitable area for tea to disseminate of tea plantations in the country. Land suitability analysis is pre-request for assigning specific land for specific purposes. The study incorporate applications of Geographic Information System, Remote Sensing and Analytical Hierarchical Process (AHP) to allocate suitability weights to criteria that influence tea plant's growth to produce a predictive suitability map for its cultivation. Topography, Soils, climatic and land use features were included in the process as an important contributing factor for tea plant's growth. Each of the evaluations criteria layers were classified into four suitability class of not suitable, less suitable, suitable, and highly suitable. The results indicated that important influential factors affecting tea cultivation suitability evaluation were Rainfall (23.9%) followed by soils pH (18.05%) Elevation (12.72%), land use (10.79%), Aspect (9.07%), soils texture (6.96%), Slope (6.43), soils Depth (5.25%) temperature (3.42%) and drainage class (3.42%) respectively with 8.23% consistency index. The results revealed that the moderately suitable suitability class occupied the largest proportion of Land (84.92%), followed by highly suitable area (11.42%) and the unsuitable area (3.66%). the study area were precipitation, soil reaction, Altitude, Aspect and current Land use were identified as main limiting factors for Tea productions.

Abstract: We live in a moment where so many unimaginable things are happening simultaneously. The most natural formation in our climatic and geological zone today is the forests. They are vital component of ecological stability, continuity of life, landscape, and balance of impurities, subsequently checking ecological dilapidation. Forests, as a type of land use, permit biological production with a market worth and assist with shaping the quality of human life and existence. Poland's timber assets have been consistently expanding, their volume remains at 2.5 billion m3 of gross merchantable lumber. Toward the finish of 2010, Poland's woodland cover estimated by the global appraisal standard added up to 30.4% and was below the European normal (32.2%, except the Russian Organization). Over the years, forests covered practically the entire area of Poland. Due to socio-economic development, however, the forest cover remained at 40%toward the end of the 18th century but dropped to 20.8% by 1945. This cycle was switched during 1945-1970 when nearly a million hectares of land was afforested, which expanded the forest cover to 27.0%. The figure has since then been fluctuating, at the end of 2014 forest area covered 30.7% and today, It 31%. This review evaluates the state of Polish forests in the past, present and suggests a strategy for the way forward through diverse means of sustainable management.

Abstract: Study is carried out at National Key Lab of Plant Cell Biotechnology, Ho Chi Minh City, Vietnam. Vietnam has planning to re-culture of coffea plant in area of over 40.000ha in South of Vietnam. Good quality of seedlings have a big demand. Using bioreactor technique is the first method to resolve the lack of seedlings. Stem, leaves of in vitro plantlets were used as planting materials. Somatic embryo callus was initiated on medium supplemented with MS+ BA (0.1mg/l) + 2iP (2mg/l) + IBA (2mg/l). Somatic cell suspension was created and proliferated on medium MS + kinetin (1mg/l) + BA (0.1mg/l) + 2iP (2mg/l) + 2.4D (1mg/l). Embryogenic suspension was stimulated on the medium MS + kinetin (1mg/l) + BA (4mg/l). In vitro shoots of coffee were regeneration on the medium MS + kinetin (1mg/l) + BA (4mg/l) + Adenin sulfate (40mg/l). Plantlets were enhanced growth and development in immersion-bioreactor cultivation by sinking/rising floated 1min/6hrs. Temperature, light intensity and stirring in stirring-bioreactor cultivation were favoured at 26±2°C, 11.1-22.2μmol/m2/s, and 30rpm. Micropropagation of coffea sp. by bioreactor technique was set up to produce 25,260 plantlets per liter of somatic embryogenesis suspension.
