Guji zone has the external favorable environmental conditions that are in favor of honey production and marketing. However, current knowledge on honey product value chain is lacking. A total of 120 households were interviewed by using semi-structured questionnaire, key informant interview using checklists were primary data collection methods. The data were collected from 11 traders and 14 honey consumers by using interviewed. The collected data was analyzed by using SPSS. The major honey value chain actors in the study area was identified input suppliers, producers, local collectors, cooperatives, wholesalers, retailers, processors and final consumers of the product. The study result showed that honey producers was constrained by Pests and Predators, absconding, lack of Bee forage, agro-chemical application, lack of beekeeping equipments, lack of institutional linkage, marketing constraints and lack of modern input supply and traditional hives bought to high price from local market. While governmental and non-governmental- organizations are identified honey value chain supporters in the study areas. Four market channels were identified. From identified honey marketing channels (producers - collectors – cooperatives – processors - consumer) are the major share of honey goes to marketing through channel II. The study suggests that beekeeping and districts agricultural development agents through provision of appropriate training and formation of beekeeper unions and cooperatives to address problems and strengthening linkage/interaction among honey value chain actors, and supportive institutions.","PeriodicalId":53319,"journal":{"name":"International Journal of Food and Agricultural Economics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88681293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coffee is one of the most important cash crops across the world and a major source of export earnings. The adoption on awareness of farmers about organic farming is one of the best preferable measures to improve both high quality and quantity of coffee production. The general objective of this study is to analyze socio-economic factors influencing farmers’ adoption of coffee organic farming in Gakenke district of Rwanda. This study employed a cross-sectional survey design and a multi-stage sampling technique was adopted to select sample for this study. Hence, the total sample size for this study was 182 respondents. Descriptive statistics such as frequency and percentage was used to analyze the first and second objectives. While inferential statistics (logit regression) was used to analyze objective three. The overall objective of the study to analyze socio-economic factors influencing farmers ‘adoption of coffee organic farming in Gakenke district of Rwanda. In this study, the majority 60.4% of the respondents were male. Result shows that farmers had high level of awareness in Recycle wastes of plant and animal (100%). The most commonly and highly adopted practices was crop rotation of intercropped crops such as bush beans, tomatoes, pineapple and vegetables in general. The result of logit regression analysis in Table 4 shows that four factors such as education level, land size, farming experience and gender had positive and significant influence on adoption of organic coffee farming. It was therefore recommended that youth should be encouraged and supported to enter this sector because they are in their active age and are more adopter of innovation than old people who are more conservators. Provision of training and technical advice on organic farming practices through agricultural extension services and developing information networks among farmers is vital.","PeriodicalId":53319,"journal":{"name":"International Journal of Food and Agricultural Economics","volume":"104 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90899774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The low adoption rate of fertilizer usage has been partly attributed to high costs of fertilizer in addition to use of agronomic recommendation without fertilizer economic analysis. The study therefore, set out to determine the profitability of fertilizer micro dosing and weeding regimes in finger millet production in eastern Uganda. A randomized complete block design in split plot treatment arrangement with three replications was used. Weeding regime treatments were the main plot and fertilizer micro dosing treatments as the sub plots. The treatments included: different micro dosing rates of nitrogen and phosphorus, weeding regimes and SEREMI II finger millet variety. Nitrogen was applied in the form of urea (46%), in two splits of 50% each at vegetative and flowering stages respectively. The results of the study indicate that weeding once at 20 Days After Sowing (DAS) and a combination of N and P (16.6 kg N ha-1 and 10.6 kg P ha-1) fertilizer micro dose application is the most profitable combination and could make farmers earn up to Uganda shillings 1,984.220 per hectare compared to only Uganda shillings 373,000 from none application of fertilizer.

With the advantage related to the higher productivity, the ever-increasing of domestic demand as a result of urbanization and population growth, rice production under smallholder farmers is expanding very fast. The study was designed to determine the cost of production and profitability of rice under smallholder farmers in the rain fed upland production ecosystem. Descriptive statistics and enterprise budget were used to analyze data collected from selected farmers. Descriptive analysis result reveals labor cost was the main cost item in rice production which took about 74% of the total variable cost, of which weeding cost took about 37%. The enterprise budget analysis reveals sampled farmers obtained gross margin of ETB 12,084.46 per hectare from rain fed upland rice production with benefit cost ratio of 1.44 and break even price and yield of 6.45 ETB per kg and 2157 kilogram per hectare, respectively and the gross margin was more sensitive for price and yield fluctuations. Thus, upland rice production is a profitable enterprise. Moreover, in order to make the enterprise more attractive, it is important to promote productivity-improving and labor-saving modern technologies and strengthen the market information delivery system and collective action by farmers.","PeriodicalId":53319,"journal":{"name":"International Journal of Food and Agricultural Economics","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74567827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four cows of same milk yield, body weight, stage of lactation, but differing parities were arranged in 4x4 Latin square design. The animals were provided with natural grass hay (T1), untreated finger millet straw (T2), EM2 treated finger millet straw (T3) and urea treated finger millet straw (T4) diet ad libitum and all treatments were supplemented with concentrate mix. Results of chemical analysis of the treated finger millet straw showed that the treated straw had good nutritive value. The daily dry matter (DM) and crude protein (CP) intakes were significantly (P<0.001) different among the treatments with the highest intake observed for cows fed EM2 and urea treated finger millet straw (T3 and T4). Milk yields varied significantly among the dietary treatments with the lower mean milk yield recorded for cows in T1 and T2 as compared to those in T3 and T4. This study indicated that EM2 and urea treated finger millet straw diet increased the net return. Feeding EM2 and urea treated finger millet straw with concentrate mix was found to be an effective approach to maximize the utilization of locally available feed resources for relatively high animal productivity during the dry season for small scale dairy keepers in rural areas. Therefore, the result demonstrated that EM2 and urea treated finger millet straw had better feeding value as compared to untreated finger millet straw and natural grass hay for lactating crossbred dairy cows.","PeriodicalId":53319,"journal":{"name":"International Journal of Food and Agricultural Economics","volume":"57 2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83392456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The evaluation indexes were selected based on the instruction of the U.S. Soil Conservation Service (SCS) and American Society of Civil Engineers (ASCE). Parameters of the absolute emission uniformity (EU), the statistical uniformity of Coefficient (Us), efficiency reduction factor (ERF), and flow rate coefficient of variations were obtained. The results indicated that 43.7 percent of the projects being studied had a very good statistical emission uniformity and 31.3 percent showed a Poor and average statistical emission uniformity and 25 percent of the projects had an unacceptable statistical emission uniformity. The flow rate non-uniformity of the droppers and the resulting low coefficients indicated the manipulation of the droppers. The average ERF is 0.717 in the selected projects, which is due to the non-supply of the pressure required in the irrigation systems. The dependence of the Farmers and agricultural operators on government’s aids is one of the main challenges and obstacles of the growth of agriculture and stable productivity in the region.","PeriodicalId":53319,"journal":{"name":"International Journal of Food and Agricultural Economics","volume":"475 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78519821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, information on the cost-effectiveness of such drying systems for decision-making by investors is lacking. This study seeks to assess the financial and economic feasibility of a solar-biomass hybrid dryer for maize drying. A cost-benefit analysis was done using net present value (NPV), benefit-cost ratio (BCR), and internal rate of return (IRR) as well as payback period to measure the financial viability of the dryer operation and the profitability of the investment. The results show that the total capital expenditure required to establish the drying system is $ 5,263 with a running cost of $ 1,166 per year. Using an economic utilisation period of 10 years, the investment in the dryer was determined to be viable with an NPV of $ 4,876 and an IRR of 38% at a capital cost of 24%. At a drying charge of $2.11/bag, the results show the initial capital invested can be recouped in a PBP of 2.7 years at a BCR of 1.48. These financial indicators suggest that investment in the dryer is profitable. Further analysis shows that, at a projected 30, 266.80 tonnes of maize produce per season by smallholder maize farmers in the study area, about 210 of the hybrid dryers are needed to provide drying services to the farmers. This translates into about 420 direct job opportunities created for the youth and the potential to prevent economic loss of maize grains equivalent to $ 5,684.2 per year due to post-harvest losses of maize in the study area. The adoption and scale-up of the dryer have implications in addressing maize post-harvest loss at the smallholder level and job creation for the youth in the country.","PeriodicalId":53319,"journal":{"name":"International Journal of Food and Agricultural Economics","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80094097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resultant effects are obscenest and foulest recital in agricultural productivity which culminate in food insecurity, impoverishment and deprived national economy. This study examined climate smart agricultural practices among maize farmers in Funtua agricultural development zone of Katsina State. Primary data was collected with the aid of structured and pre-tested questionnaire administered to One hundred and sixty respondents using multi-stage sampling technique. Questionnaire administration was done by the researchers abetted by trained enumerators. Data collected from respondents was analyzed using both descriptive and inferential statistics. Socio-economic diagnosis shows that the mean age of the respondents was 48 years. This suggests that majority of the maize CSAP practioners in the study area are in their youthful age and mainly (53%) are fully involved in maize farming with majority (75%) having more than 11 years maize farming experience. This implies that most of the maize farmers are energetic, this can translate to better performance in maize farming activities. The majority of the farmers (68%) are educated. This would further enhanced in espousal of CSAP technology. The study further revealed that the most CSAP techniques in the study area is minimum tillage and mixed farming as used by 90% of the respondents, while about 85% of the maize farmers interviewed practiced cover cropping. Inferential statistics reveals that coefficient of multiple determination R-squared value of 51.5%. Three out of seven exogenous variables were significant, these are Household size, farm size and education. Household size was negatively significant (P < 0.01). It implies that an increase in the size of the farming household would decrease the practice of CSAP in the study area. Education was positively significant (P<0.01). This connotes that advancement in farmers education will influence the practice of CSAP in the study area. Farm size was positively (P < 0.1). This implies that an increase in the farm size will stimulate the practice of CSAP among the maize farmers. The study concludes that there are ample evidences of CSAP activities among maize farmers in Funtua agricultural zone. The study recommends that bottleneck occasioned from non-availability of land for maize production should be tackled through government intervention. Knowledge update with respect to CSAP farming techniques should be championed by the farmers’ group and agricultural institutions. Household size should be regulated and synchronized with focus on agricultural productivity.","PeriodicalId":53319,"journal":{"name":"International Journal of Food and Agricultural Economics","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79013658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Crop water requirement and irrigation scheduling of maize in selected districts of Metekel zone were estimated using CropWat model based on soil, crop and meteorological data, and AquaCrop based on soil, crop and meteorological data including Co2, groundwater, field management, and fertility status. Model performance was evaluated using Normalized Root mean square errors (NRMSE), model by Nash-Sutcliffe efficiency (NSE), Prediction error (Pe), and Model efficiency (MF). It is observed that the maximum reference evapotranspiration in the study area was found to be 7.1 mm/day in Guba and the minimum reference evapotranspiration was 2.9 mm/day in Bullen district. In all cases, the maximum ETo in all districts was fund to in March and the lowest in August. The maximum ETc of maize was found to be 702.4mm in Guba district and the minimum ETc was found to be 572.6mm in Bullen district using CropWat but the effective rainfall (Pe) for maize was determined as 185mm respectively in Wembera district. However, using the AquaCrop model the maximum ETc of 565 mm was recorded in Guba but 425 mm was recorded as a minimum in the Wembera district for irrigated maize in the study area. The study revealed that the irrigation scheduling with a fixed interval criterion for maize 10 days with 12 irrigation events has been determined. Moreover, furrow irrigation with 60% irrigation application efficiency was adjusted during irrigation water applications for all districts. The performance of the irrigation schedule and crop response was evaluated by the analysis results in the simulation using different models. It has been observed that there were a strong relationship and a significant relation between the simulated and observed values for validation. Hence, Normalized Root mean square errors (NRMSE), model by Nash-Sutcliffe efficiency (NSE), Prediction error (Pe), and Model efficiency (MF) showed that the AquaCrop model well simulated in all parameters considered. AquaCrop model is the most suitable soil-water-crop-environment management model, so future studies should suggest a focus on addressing deficit irrigation strategy with different field management conditions to improve agricultural water productivity under irrigated agriculture for the study area for major crops.","PeriodicalId":53319,"journal":{"name":"International Journal of Food and Agricultural Economics","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91002764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
