Abstract: The objective of this experiment was to determine the response of snap bean varieties to different rates of cow dung vermicompost and their interaction effects. A 3×4 factorial experiment arranged in a randomized complete block design (RCBD) with three replications was carried out under Lath house condition. Factor one consisted three varieties of snap bean (Plati, Faraday and BC4.4), while Factor two consisted four rates of cow dung vermicompost application rate and 1 recommended rate of NPS (R5). The results revealed that, the main effects of vermicompost rates and snap bean variety showed significant difference (P≤0.05) for all growth parameters studied except for total leaf chlorophyll content. Accordingly, the interaction effect of vermicompost rate and variety were significant for Plant dry weight. Therefore, taking the findings of the present study in to consideration, it may be tentatively concluded that, the farmers at the Jimma may apply the combination of 45t/ha cow dung vermicompost and Variety BC4.4 would help to improve the growth of Snap bean. However, repeating the same study across season and location at field condition would help to draw sound conclusion and recommendations. Hence, future studies should look in to these factors to develop cow dung vermicompost fertilizer and snap bean varieties recommendation for optimum growth of snap bean in Jimma area.

Abstract: Ethiopia is the second largest wheat producer in sub-Saharan Africa, after South Africa. In Ethiopia, wheat ranks fourth in total cultivated area and production. This study applied logit regression to examine determinants of adoption of improved wheat varieties in the Liban jewi district of West Showa zone Oromia region Ethiopia. The objective of the study is to analyze determinants that affect adoption of improved wheat varieties which exert significant influence on the adoption behavior of sample respondents in the study area. A total of 154 sample respondents drawn from 6 PAs of the district included in the survey. The model result shows that the adoption of improved wheat varieties by respondents in the study area was positively and significantly affected by farm size, livestock ownership, extension contact and access to credit, whereas, age of respondents, distance from market and distance from farmers training center had negatively and significantly influenced adoption of improved wheat varieties in the study area. The result underscores the need for research and extension programs to be sensitive to the needs of farmers when developing and disseminating technologies that are relevant to their agro-ecologies.

Abstract: Ornamental potted plant are often proposed as a passive approach for improving indoor air quality (IAQ). Volatile organic compounds (VOCs) enter indoor environments through internal and external sources. Indoor air concentrations of VOCs vary greatly but are generally higher than outdoors. Plants have been promoted as indoor air purifiers for decades, but reports of their effectiveness differ. The aim of this study was to determine the selective of several potted indoor and outdoor species plants which can sustain and improve indoor air quality by using the native species plants. The experimental design was a complete randomised design experiment with four replications and it was conducted at the Horticulture Research Centre laboratory. Different native ornamental potted plants species such as Eugenia sp.; Scindapsus pictus; Schismatoglottis sp.; Tradescantia pallida; Piper porphyrophyllum; Alocasia reginula; Ledebouria socialis; Peperomia sp. and Ledebouria petiolata respectively had a different significant effects on absorption of the VOCs gases. The maximum and significant absorption of potted indoor plants species tested sequently was from Ledebouria socialis; Eugenia sp.; Piper porphyrophyllum; Peperomia sp.; Scindapsus pictus; Tradescantia pallida; Ledebouria petiolata; Alocasia reginula and Schismatoglottis sp. The leaf area, having moderate function of VOCs gas absorption did not drastically reduce the VOCs gas volume. Overall, the data from the laboratory studies illustrate the potential for indoor plants leaves to be used as air purifier and indoor air VOC samplers.

Abstract: On farm verification trial of soil test based crop response phosphorus calibration study on bread Wheat was conducted at Yaya Gulele district of North Shewa zone during 2018 cropping season using optimum amount of nitrogen (92kgN/ha), critical P-value (23ppm) and Phosphorus requirement factor (3.7) determined during soil test based crop response phosphorus calibration study in the year 2017. Using the equation (23-pi)×3.76 which were developed during calibration study, verification trial was conducted on farmer’s field of land unit 10m by 10m in the same districts with the objectives to verify research finding obtained from P-fertilizer Recommendation study on bread wheat crop and to provide site specific soil test based P-fertilizer recommendation. Soil test based P- calibration result (T3), Farmers’ practice (T2) and the control (T1) were the treatments. The trial was laid out in RCBD considering farmers as replications. Analysis of Variance indicated that there was significant difference (P<0.05) for the treatments tested as fertilizer rates. The highest mean grain yield (37.13 qt/ha) was recorded with soil test based P -calibration result (STBPCR) which was significantly higher than farmer’s practice (21.98 qt/ha) and followed by the control. MRR range from 857.27% in STBFR to 738.01% in farmer’s practice. Agronomic data were collected on heading date, maturity date, plant height, and Stem length, and Spike length, biomass and grain yield. Therefore, it is concluded that for obtaining aimed yield target and profit with sustenance of soil fertility in Yaya Gulele Districts, the optimum rates for wheat Production were found to be 200 kg/ha Urea (92 N/ha) and Soil test based P-fertilizer recommendation could be followed for wheat Production.
