Abstract: The experiment was conducted to investigate the effects of different imported fish feeds on the performance of juvenile African Catfish (Clarias gariepinus). A-13 week feeding trial was conducted using 225 juveniles which were randomly assigned to five treatment groups in 15 indoor plastic tanks at a stocking rate of 15 fish per tank and three (3) replicates per treatment. The fish were fed at 5% body weight, twice daily. The five treatments were Coppens (T1), Aqua (T2), Ranna (T3), Pira (T4) and Durante (T5). Data for each parameter was subjected to one-way analysis of variance (ANOVA) while means of various results were compared at 5% level of significance. There were significant differences (P<0.05) in the weight gain among the treatments, with 54.07g and 21.73g for fish fed with Aqua and Rana respectively. Also, there were significant differences in the specific growth rate (SGR) as well as the protein efficiency ratio (PER) among the feed brands with Aqua and Rana having 2.79 and 1.97 as well as 1.49 and 1.12 respectively. In all the treatments, there were significant differences (P<0.05) in the survival rates of the fish with the highest percentage in fish fed with Coppens (93.33%). A kilogram of Aqua and Pira feeds each cost $1.75 while the estimated costs of feeding one individual fish to a weight gain of 1kg using the same feeds were $2.78 and $3.73 respectively. Although, from this feeding trial, it is expensive to raise a kilogramme of fish using Pira fish feed, but due to the high survival rate, it is recommended for catfish production. It is assumed that the biomass harvested will make up for the cost incurred.

Abstract: Cross Correlation (CC) analysis provide a correlation between two time series. The observations of one series are correlated with the observations of another series at various lags and leads. CC analysis also help in identifying variables which are leading indicators of other variables or how much one variable is predicted to change in relation of the other variable. In this paper we attempt study the relationship between monthly maximum temperature and relative humidity in Bida, Niger state from 1981 to 2012 collected from the NCRI, Baddegi. The results revealed that there is a negative relationship between Temperature and relative humidity in Bida. Also negative relationship is revealed at lag 0, positive lags of 1, 2, 9, 10, 11, 12 and 13 while for negative lags of 1, 2, 3, 10, 11, 12, and 13. We recommended that our work will be helpful to farmers, statisticians and to Agricultural Economist and Econometrician to understand the interrelationship between these variables and to take appropriate action or caution.

Abstract: Ethiopiahas suitable environmental condition for potato production. However, the productivity of potato is very low as compared with world average due to lack of stable, high yielding, and disease resistant cultivars. Therefore, the objective of this study was to evaluate the promising genotypes and verify the most stable, high yielding and disease resistant potato genotype for highlands of Bale. For the study, the experiment was carried out at three locations from 2009 to 2011 production seasonusing 11 genotypes including local and standard checks. Randomized complete block design with three replications was used for the experiment. One of the experiments was conducted at the research farm of Sinana Agricultural Research Center, Oromia Agriculture Research Institute, Sinana and the others at the farmers’ field, Dinsho and Shalo. The study found that the Milki (CIP-394640.539) varietyhad above average yield performance in most test environments, out yielded the Jalane, Ararsa and Hunde. The average tuber yield of Milkiover locations and over years is about 49.31 t/ha. It has also better yield stability than checks. Milkiis, therefore, released in 2012/13 for production for all potato growing environments in the highlands of Bale and other similar agro-ecologies.

Abstract: This fertilizer experiment was undertaken at Bule hora district, Eastern Guji zone, southern Ethiopia in 2016. The objective of the experiment was to study the effect of different NP rates on the yield and yield components of Irish potato to determine biological and economic optimum NP rate at the area. Adapted and recommended variety of Irish potato variety (Gudane) was used for the experiment under rainfall. The treatment consisted of combination of five levels of N (0, 50, 80, 110 and 140 kg N ha-1) and four levels of P (0, 45, 90 and 135 kg P ha-1). Data were collected on parameters like plant height, number of branch per hill, tuber weight, marketable yield per hectare, unmarketable yield per hectare and total yield per hectare. ANOVA and Partial budget analysis were used to determine biological and economic optimum NP rate. Tuber yield was significantly affected by both P and N levels. There was also a significant N and P interaction effect on tuber yield. The maximum total tuber yield (195.06qt ha-1) was obtained when 50 kg N ha-1 and 135 Kg P ha-1 were combined, and it was closely followed by 193.21 qt ha-1 obtained at 110-90 kg ha-1 NP combinations, resulting in grain yield benefit of 361 and 358% over the control, respectively. Almost all collected parameters were significantly affected by P rate but did not respond to N rate. This could be due to substantial amount of total N in the soil (0.61%) which was in the high range. As to partial budget analysis, treatment 110-90 kg ha-1 NP combination had highest net benefit and acceptable marginal rate of return (473.67%). Based on this experiment, 110-90Kg ha-1 NP combination was found profitable and recommended for Irish potato farmers of Bule hora district and similar areas.

Abstract: The study was conducted in Malga district of Sidama Zone in Ethiopia to describe the socioeconomic characteristics of households and identify factors governing the intensity of barley adoption. The district was known with barley production. The study used both primary and secondary data. Multistage sampling techniques were used to select three peasant associations and 129 barley producing households. Descriptive statistics (mean, standard deviation and frequency) was used to describe variables under consideration whereas econometric model (Tobit) was applied to and identify the factors governing the adoption of improved barley. The result of analysis revealed that age, farm experience, oxen, membership of cooperative, distance to all weather roads and annual income were found to be significant variables affecting the intensity of barley adoption. Therefore, infrastructural development, providing inputs access, creating financial viability and strengthening farmer’s organization are areas that need policy attentions.

Abstract: Horticulture is the branch of agricultural science that uses technology and marketing strategies to increase vegetables, fruits, flowers and ornamental plants production for human welfare. In Ethiopia, more than 85% of the population depends on agriculture. However, agricultural production is less due to lack of advanced agricultural technologies and yield losses caused by damaging pests, diseases and environmental conditions. Many farmers in west and southwest Shewa zones also depend on agricultural production especially cash crops like fruits and vegetables. The study was conducted in the seven districts producing major horticultural crops and the data collection was done in May 2013. The study districts did not have enough information on horticultural crop cultivation constraints and opportunities. Data on horticultural crops constraints and opportunities were collected based on prepared questionnares with group discussion of farmers and other responsible bodies. The two zones are suitable for growing of various horticultural crops. Farmers are faced a lot of problems such as abiotic (lack of pure planting materials, long chain marketing systems and adverse environmental factors) and biotic factors (fungus, bacterial and insects) on the horticultural crop production.

Abstract: The study analysed off-farm activity participation and determinants for rural households in Northern Province of Zambia. The multinomial logit (MNL) model was used in estimating factors influencing the households’ choice of off-farm activity. Secondary data for the 2012 Rural Agricultural Livelihoods Survey (RALS12) from Central Statistical Office (CSO) of Zambia, which used a multistage sampling method, was utilized. Cross sectional data for 1,000 farm households was used in this analysis. The findings shows that 46.40% of the respondents do not combine agriculture with off-farm activities. The age, education, number of adult household members, farm size, cooperative membership and extension service access were key significant determinants of households’ participation into off-farm activities. This shows the need for off-farm activities to be part of rural development policies. The interventions should also be designed to suit the needs and situations of different categories of the households in the study area.
