title: AMMI Analysis of Yields and Oil Content in Some Linseed (Linum usitatissimum L.) Genotypes in South and Central Ethiopia

description: Linseed (Linum usitatissimum L.) is important to the Ethiopian farmers in terms of its various home uses generating potential in both domestic and foreign markets. One of the major linseed production constraints in the country is the lack of high yielding and high oil content varieties. This experiment was conducted at Hossaina, Kokate, Dida-Midore and Holeta to assess the genotype-by-environment interaction (GEI) among the varieties for yield and oil content. The experiment was carried out using nine released out and three pipeline varieties with a local cultivar. The analysis of variance of AMMI exhibited a very highly significant (P ≤ 0.001) variation due to varieties and locations for grain yield, oil content and oil yield, but GEI was significant for oil content and oil yield and not for grain yield indicating that the stability of the genotypes over the range of locations tested. The genotypes CI-1652, Tolle, Kassa-2, CI-1525, Jeldu, and Kulumsa-1 for oil content and the genotypes Kassa-2, Jeldu and CI-1525 for oil yield formed the first adaptive group with high mean and IPCA1 closer to zero IPCA1 indicating that they were the most stable and had wider adaptability across the studied environments. The AMMI selections for oil content and yield per environment included Kassa-2 in all the four locations; Jeldu in Holeta and Kokate; Kulumsa-1 in Dida-Midore, Hossaina and Kokate; CI-1525 in Holeta and Hossaina; Dibannee in Hossaina for both oil content and oil yield but in Kokate only for oil yield.

title: Assessment of Food Insecurity and Coping Mechanisms among Pastoral Households of Afar National Regional State: The Case of Chifra District, Ethiopia

description: Inspired by the current vulnerability of pastoral households, this study was carried out in Chifra district of Afar National Regional State; Ethiopia, with specific objectives of assessing the status of food security, the local food insecurity coping strategies employed by different food security status groups and identifying the major determinants of food insecurity. In order to achieve these objectives cross-sectional data on demographic and socio-economic characteristics, and institutional aspects were collected from 120 households that were drawn by a multi-stage sampling procedure from 3 randomly selected Pastoral Kebeles through structured interview schedule and focus group discussion during January and February 2011. The main tools of analysis for this study include descriptive and inferential statistics and binary logit econometric model. Results of descriptive and inferential statistics indicate that using the calorie intake approach, 65.8% of sample respondents were food insecure, while 34.2% were food secure.Further analysis showed that sale of sheep and goats (shoats), reducing number and size of meals; seasonal migration (some of the family members), receiving food aid and borrowing cash or food from neighbors or relatives were the frequently practiced copping strategies by pastoralists of the study district. On the other hand, analysis of the logistic regression model resulted in eight statistically significant variables affecting the food security status of the sampled households in the district. Family size, age of household head, dependency ratio, livestock disease incidence were causing food insecurity whereas sex of household head, herd size, income from livestock production and non-farm income were working against food insecurity. The study recommends that appropriate policy measures be taken towards limiting dependent population size through integrated and accessible health and education services, improving the contribution of the pastoralist women through trainings that could help remove cultural barriersand supporting the livestock sector through proper forage development as well as extended veterinary service and disease control programs.

title: Growth and Yield Components of Tomato as Influenced by Nitrogen and Phosphorus Fertilizer Applications in Different Growing Seasons

description: Tomato is an important cash crop in Central Rift Valley of Ethiopia. However, the yield is constrained by poor soil fertility management and lack of appropriate/adequate fertilizers rates recommendation. Experiments were conducted at Melkassa on station with the objectives of evaluating effect of N and P fertilizer applications on growth and yield, and determining optimal requirements for tomato. The experiments were conducted under both cool season furrow irrigated and rain-fed conditions with variable fertility status of the fields. The treatments consisted of four rates of nitrogen (0, 50, 100 and 150 kg N ha-1) and four rates of P (0, 46, 92 and 138 kg ha-1). The experiments were laid out in a CRBD in a factorial arrangement and replicated three times using Melkashola variety. Data on growth and canopy characteristics such as plant height and stem diameter, main lateral branch length, canopy width and depth were measured from selected plants. Some of the growth and yield components such plant height, canopy diameter, canopy width, stem diameter, lateral branch length, total dry mass above the ground per plot, shoot fresh and dry weight, marketable and unmarketable fruit yield and total yield at harvest were measured were assessed. Maximum fruit yield was estimated from regression lines of applying 105 kg N ha-1 and 85 kg P ha-1 under furrow irrigated experiment (continuously cultivated field). However, the highest fruit yield was from application of 40 kg N ha-1 and 10 kg ha-1 for the rainfed experiment (relatively fertile field). Thus, results of both experiments were averaged to propose on farm verification of N and P requirement of tomato, N 73 kg ha-1 and P 48 kg ha-1 around Melkassa and similar soil types.

title: Effect of Planting Methods on Maturity and Yield of Onion (Allium cepa var cepa) in the Central Rift Valley of Ethiopia

description: Onion dry bulb are commonly established in the field either by direct sowing of seeds to the field, or by transplanting seedling from seedbed or from sets depending on the growing conditions of the specific region. However, the potential of the different methods have not been tested particularly in the potential onion producing areas of Ethiopia. Field experiments were conducted at Melkassa Research Center of Ethiopian Institute of Agricultural Research to investigate the effect of different planting methods on maturity and dry bulb yield of onion in two different seasons in 2008/09. The experiment consisted of three planting methods of onion, namely direct seeding to the field, transplanting of seedlings and planting sets, and three onion cultivars (Adama Red, Bombay Red and Nasik Red), arranged in factorial split plot design with three replications. Cultivars were assigned to the main plot and planting methods to the sub-plot. Data on days to maturity, dry bulb yield, bulb weight and bulb diameter were collected. Planting methods and cultivars showed statistically significant difference (P&lt;0.01) both for earliness and dry bulb yield. However, their interaction was not significant. Sets planting resulted in higher yield (39.1 t ha-1) followed by transplants (36.3 t ha-1) and direct seeding (19.5 t ha-1). The cultivar ‘Bombay Red’ (33.3 t ha-1) gave significantly higher yield than ‘Adama Red’ (31.1 t ha-1) and ‘Nasik Red’ (30.2 t ha-1). Sets matured earlier (94 days) than transplants (104 days) and direct sown (135 days). The overall result indicated that in addition to the current transplanting practice onion establishment from set may also be a good option for dry bulb production in the Central Rift Valley areas of Ethiopia where earliness and high yield are important parameters considered by onion growers.

title: Determinants and Coping Strategies of Household Food Insecurity in Rural Areas of Tigray: The Case of Rural Adwa Woreda

description: This paper identified the major determinants of household food insecurity and their local coping strategies based on primary data collected from 180 randomly selected households of rural Adwa Woreda, Tigray National Regional State. To assess the determinants of food insecurity binary logit model is employed. The extent and magnitude of household food insecurity, food expenditure inequality, and the coping strategies of the food insecure households are also identified using indices of Foster, Greer and Thorbecke (FGT), Gini Coefficient, Lorenz Curve and Coping Strategy Index. The absolute food poverty line for the study area during the study period is estimated to be ETB 1634.75 per adult per year. The incidence, depth and severity of food insecurity are 63.33 percent, 18.82 percent and 6.99 percent respectively. Furthermore, the Gini Coefficient for the study area is found to be 31.20 percent. Among the most common coping mechanisms of households in the study area include selling household asset, leaving the entire days without eating and sending household members for beg. Access to agricultural extension services, off farm income, number of oxen owned, total land size and safety net participation are found to be the major determinants of household food insecurity that significantly reduce the level of households food insecurity in the study area. Whereas age dependency ratio, family size, crop disease incidence and fertilizer utilization are uncovered to be significant and positive covariates of household food insecurity in the study area.

title: Analysis of Historical Rainfall Data and Associated Risks on Rain-Fed Tef Production at Debre Zeit, Central Ethiopia

description: As drought is the major bottleneck for the rain fed tef (Eragrostis tef) production, developing workable strategy that can mitigate its impacts is mandatory. To draw this strategy knowledge on how the rainfall behaves in the past decades is important. The central theme for this paper is studying the rainfall behavior over the past six decades in relation to the major rainfall induced risks for the rain-fed “tef” production system using 59 years of rainfall data. Risk of dry spell during germination and flowering is computed whereas crop water requirement satisfaction index is generated using water balance approach. The study shows strong intra annual variation but no trend on the annual and monthly mean rainfall totals, and number of rain days. The existence of this intra annual variation has enabled a wide range of possible planting dates that runs from late June to late August and there was no indication of trend that the planting date has a tendency to be either later or earlier in recent years. The result also depicts once in five years early and once in nine years late onset of the rain. Existence of these wide range of possible planting dates, early and late onset of the rain, high intra year variability in rainfall amount and number of rain days and absence of any apparent trend on the rainfall amount and number of rain days may shed some light how farmers are now facing frequent extremes that may consequence frequent crop failures. This signifies the need for every year rainfall forecasts and their appropriate analysis to have successful planting as well to minimize related risks and consequently to have better and consistent production system.

title: Analysis of the Determinants of Small-Scale Farmers’ Grain Market Participations in Ethiopia: The Contribution of Transaction Costs

description: The paper is based on data collected in 2007/08 by IFPRI on smallholder market participation in Ethiopia from a random cross-section sample of 1577 households, with a focus on staple food grains and the effects of transaction and non-transaction costs on output market participations as a buyer and a seller. The multivariate Probit and multivariate Tobit models were used to identify the determinants of market participation regimes. The results indicated that demographic characteristics of the households (age and dependency ratio), production assets (own and rented-in land and oxen), land characteristics, volume of production, and households income diversification (livestock and non-farm income) affected both sellers and buyers. Transaction costs associated with ownership of donkey and access to road and market explained the variation of market participations. Regional characteristics (distances, agro-climatic conditions, etc.) also highly affected the market participation of the households.

title: Apple Based Agroforestry in Dendi Woreda, Oromiya Region: Income Contribution and Determinants for Adoption

description: A study was conducted to evaluate and compare households’ income from apple based agroforestry system and identify factors that influence its adoption by smallholder farmers in Dendi Woreda, Oromia region. Two kebeles’ were purposefully selected and from which 250 households were randomly taken, where 33 were adopters of the technology and the remaining 217 were non-adopters. To obtain the necessary information, both primary and secondary data were collected and focus group discussion was conducted. The result revealed that farmers predominantly carry out various livelihood activities such as production of grain crops, livestock, vegetables, and apple fruit. In agri-horticulture agroforestry approach apple trees were integrated with vegetables at homesteads by adopters. The mean gross income of adopters from apple fruit was 58,234.85ETB ha-1 yr-1. Adopters’ mean annual gross income from vegetable + apple fruit was 344,602.3ETB ha-1 yr-1 and mean annual gross income of non-adopters from vegetable was 219,932.9ETB ha-1 yr-1. The income obtained from apple contributed 17 per cent to the income of the agri-horticulture system. Non-adopters annual net income from vegetables was 191,645.13ETB ha-1yr-1 and adopters’ annual net income from vegetable + apple was 312,378.79ETB ha-1 yr-1. The agri-horticulture system contributed 1.63 times higher net revenue for adopters in addition to its nutritional value. However, adoption of apple based agroforestry system was significantly influenced by different factor such as age (+), formal education levels (+), livestock holding (+), distance from market to home (+), sex (-) and total land holding (-). In order to maximize the benefits from the system land users are advised to follow integration of apple fruit trees in their food production activities incorporating their own farm resources to minimize input costs. Policy makers are also expected to advocate the systems performance in the study area and beyond.

title: Economics of Selected Water Control Technologies and their Successful Use: The Case of Ethiopia

description: Using a production function, marginal productivity of farm inputs and benefit-cost analysis, we explore the economics of selected water control technologies. From the production function, all farm inputs, including irrigation water is found to have a significant and positive effect on yield. Marginal value products of farm inputs are found to be positive but their magnitudes differ by type of control structures, crop type, agro-ecology and regions. The net present values of all water control structures are positive. There is a favorable precondition for sustainable adoption of these controls technologies and institutionalizing some sort of cost recovery schemes. The level of education, the ratio of irrigated land allocated to irrigated annuals and perennials, access to markets and off-farm income are found to have significant effect on successful use of these control structures. Recommendations and policy implications are drawn accordingly.

title: Suitability of Various Lignocellulosic Substrates for Cultivation of Pleurotus sajor-caju (Oyster Mushroom)

description: The objective of this study was to look into the possibility of using the different lignocellulosic biomasses for Pleurotus sajor-caju (oyster mushroom) cultivation. The mushroom species was cultivated on nine types of substrates; namely three acacia species, three types of straws, coffee husk and saw dust obtained from two types of timber species. Thirty types of treatments (pure and mixed) were used to grow the mushroom and significantly differing results were obtained. Yield data (biological efficiency, spawn running period (SRP) and days to first harvest (DFH) of the mushroom were measured. The shortest SPR and DFH were from the pure chopped barley straw (BS) followed by pure wheat straw (WS) and Acacia drepanolobium (DC), respectively. The maximum period was from the mixed sawdust of Aningeria adolfi-friedericii (AS) and Cupressus lusitanica (CS) in the ratio of 4:6. The least mushroom biological efficiency was also from the ASCS4 (4:6) mixture. No any fruit body appeared on the pure C. lustanica sawdust (CS) and the mixture of ASCS in a ratio of 3:7. On the other hand, the maximum biological efficiency of the mushroom was obtained from DC followed by BS, WS and SC, respectively. In conclusion, mushroom biological efficiencies of the pure A. drepanolobium and A. seyal substrates were found to be better than those of the mixed ones. These biological efficiencies were also found to be better than those of the agri-residues.
