Abstract: Haricot bean (Phaseolus vulagris L), locally known as ‘Boleqe’ is a very important legume crop grown worldwide. The study was initiated to assess the performance of haricot bean cultivars in relation to growth parameters and to estimate the analysis of growth characteristics. The experiment was conducted during November 2016 up to January 2017 at the compound of Hawassa University in the College of Agriculture during of season. The treatment consists of three Haricot varieties namely; Hawassa Dume, Omo-95 and Red Wolayta were used for test. The experiment was arranged in RCBD with four replications. The data were collected are Days to 50% emergence, Leaf area (cm2), Stem and leaf dry weight (gm) and calculated on Specific leaf area, leaf area ratio, net assimilation ratio and relative growth rate and Biomass dry weight were collected. Analysis of variance showed that the collected data were significantly different with respect to varieties. From the result in terms of (specific leaf area and leaf area ratio) the varieties which show higher value at the first sampling will show also increased value at the second sampling and vice versa. Growth parameters showed increment from the first sampling to the last sample which indicates difference varieties in growing environment. Generally growth parameters showed an increment from emergency to maturity.

Abstract: P. quadrifida is a juicy, mat-forming species and a widespread weed, which is highly appreciated for its high nutritional and medicinal value. It has been used as a nutrition and medicine since thousands of years ago. This is an important wild herb naturally found as a weed in field crops found in the world especially in India. In Ethiopia, particularly in western part of the country, societies use this plant aerial part as a food without perceive the nutritional quality and its appropriate harvesting stage. This study aimed to evaluate the effect of three harvesting stage on proximate composition and mineral content of the vegetable. All extracts showed noticeable amount of moisture, ash, crude protein, crude fat, crude fiber, carbohydrate, and minerals content (Calcium, Magnesium, Phosphorus, Iron, Potassium, and sodium) of this vegetable at each optimum harvesting stage. The proximate composition and mineral content of this leafy vegetable aerial part was evaluated and the result of mean value obtained were showed as follow: moisture (81.17 - 89.25%), crude proteins (1.187 - 2.186%), crude fibers (1.483 - 2.157%), ash (1.814 - 2.41%), carbohydrates (2.866 - 12.916%), crude fat (0.117 - 0.16%) and food energy (19.18 - 57.85 kcal/100g). The mineral contents were good with significant amount of K (211.70- 249), Ca (109.25 -133.21), Mg (63.04 - 84.74), P (103.71 - 136.14), Na (61.96 - 83.90) and Fe (3.06 - 4.34) mg/100g of extracted sample. The studied vegetable has low fat content at all harvesting stage. The herb has energetic values of 57.85kcal/100g at post-flowering followed by pre-flowering with energy value of 30.39kcal/100g and flowering stage having the least energy value of 19.18 k cal/100g in the food.

Abstract: Rainfall variability is one of the most influential climatic factors that determine crop productivity. This study was conducted to analyze rainfall variability and its impact on potato productivity for the period of 2000-2019, and to assess farmer’s perception on impacts of climate variability and evaluate their adaptation measures for potato productivity in Haramaya District. Primary data were obtained from randomly selected farmers through questionnaire, key informants interview and field observation. Secondary data on rainfall and potato production were collected from Ethiopia Meteorological agency and Haramaya District Agriculture Office. Purposive sampling was used to select 362 farmers in the district. Proportionate sampling was used to select the sample of farmers in each of the three kebeles (Tiniqe, Tuji Gabisa and Kuro). The data collected were analyzed using Statistical software SPSS. Annual rainfall and potato yield showed decreasing trend from 2000 to 2019. Annual rainfall trends variability was significant and ranged from -25.25 in 2009 to +48.99 in 2007. Annual Potato yield trends variability was also significant and ranged from -33.14 in 2000 to +60.89 in 2007. Rainfall variations, crop diseases, pests, and high cost of inputs have been the major challenges facing potato production in the study area. Forty three percent (43%) of the respondents agreed that rainfall variation was the main cause of decreased potato yields 24% crop diseases and pests and 15% high cost of inputs 10% inadequate improved seed and 8% soil erosions. From the findings Pearson’s r=0.668 showed that there was significant impact of rainfall variability trend on potato yields. From the findings, the study recommended that soil and water management practices such as mulching, digging of trenches, water harvesting, crop diversification and use of irrigation during the dry spell as adaptation measures should be applied to cope with rainfall variation.

Abstract: Updated information on status of soil fertility and the soil plant nutrient relationship is important for soil fertility improvement and subsequently increases crop yields. The study was conducted to assess soil fertility status of sorghum fields and micronutrient concentration in sorghum tissues and examine the relationship between soil and sorghum tissue test micronutrient at Daro Labu district, Eastern Ethiopia. Twelve sorghum growing fields from four kebeles were selected purposively. Field survey was conducted to collect general information about soil fertility management practices and record spatial data. A total of 12 composite soil samples from the depth of 0-20 cm and 12 sorghum tissue samples were collected. The data were analyzed by using SPSS version 20. The soil texture was sandy clay loam and sandy loam. Soil bulk density was ranged from 1.35 to 1.53 g cm-3 within an acceptable range. The total porosity of soil was ranged from 41.49 to 45.27%. The soils were very low in OM content with values ranging from 0.60 to 1.18%. The TN content of soil was ranged from 0.06 to 0.14% which was low. The soils were better in their available P content. The CEC of soil ranged from medium to high. Exchangeable Ca and Mg were found to be high and medium respectively. Exchangeable K was low to medium which showed deficiency of K. The soil had adequate level of DTPA extractable Fe and Mn whereas deficiency of Cu and B was recorded. The 75% of soil was showed Zn deficiency. Sorghum tissue had adequate concentration of Fe and Mn. However, 66.67%, 16.67% and 58.33% of sorghum tissues were deficient with Cu (0.35 - 10.53 mg kg-1), Zn (7.06 - 20.39 mg kg-1) and B (0.18 - 4.69 mg kg-1) concentration respectively. The extractable Fe, Mn, Cu, Zn and B concentration in a plant tissue were positively correlated with their respective soil micronutrients. The soil of the study areas were at normal condition in terms of the studied soil physical properties. The data regarding chemical fertility parameters indicated that OM, TN, P, K, Cu, Zn and B are the main limiting factors for crop production. Therefore, application of organic materials (compost, vermicompost, FYM, crop residue management) and balanced minerals fertilizers containing K, Cu, Zn and B could be recommended. Moreover, further studies on application rates of those fertilizers by considering soil type and crop variety are suggested.
