Therefore, soil amendment is important to improve soil nutrient either by organic or inorganic technique. In this paper, we considered different inorganic fertilizers to determine the main optimal effect and their interaction on the yield of crop by adoption of mixed-level factorial experiment. Three inorganic fertilizers namely Nitrogen (N), Phosphorous (P) and Potassium (K) were considered each at different levels using tomato crop for investigation. We set up a multiple linear model to match with the design. We estimated the model parameters with the error component and sums of squares. A 2×3×4 design structure for factorial combinations—of factor N at two levels, factor P at three levels, and factor K at four levels using a randomized complete block design with three replications—was developed. Normality of the data was tested and factors visualization for both main and interaction effects were illustrated by the use of graphs. The result revealed that Nitrogen (N) and Potassium (K) concentration are significant while Phosphorous (P) concentration is not, the effect of two-factor interactions for NP and PK are not significant and NK is significant, which signified that the yields do not depend on the levels irrespective of the factor. Based on the results, we concluded that phosphorus is the best inorganic fertilizer compared with Nitrogen and Potassium in terms of soil nutrient for the yield of crops.","PeriodicalId":253942,"journal":{"name":"Research Journal of Agricultural Economics and Development","volume":"1 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141640675","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}

{"title":"Perceived Effects of Climate Variability on Crop Production in Imo State, Nigeria","authors":"Nwaeboh A. V., Egwuonwu H.

Climate variability has direct impacts that cause vulnerability to the natural and social systems through changes in average temperatures, temperature extremes and extreme weather events like flooding and droughts. The study described the socio-economic characteristics of the crop farmers, ascertained crop farmers’ knowledge on climate variability, determined the perception of farmers on climate variability, and examined the perceived effects of climate variability on food crop yield production. A multistage sampling procedure was used in the selection of one hundred and eighty-three (183) crop-based farmers. Structured questionnaires were used in obtaining data and the data collected were analyzed using frequency, percentage, mean score and multiple regression analysis. Findings show that the mean age was 48.77 years. Majority (71.58%) were females. Majority (78.14%) were married with an average household size of 8 persons. Most (65.57%) had secondary education with an average farming experience of 21.18 years. Average farm size and farm income were 1.24 hectares and ₦33,000.00 respectively. Findings show that farmers had major knowledge of climate variability as zero/minimum tillage practices (99.45%) and knowledge on rain-water harvesting (97.81%) amongst others. Farmers perceived climate variability (x̄ = 3.49), starts late and ends early (x̄ = 3.45), extremes in temperatures (x̄ = 3.39), too much/heavy rains (x̄ = 3.396) and long dry spells during the season (x̄ = 3.51), amongst others. Crop farmers further perceived that climate variability has resulted in declining crop yields (x̄ = 3.35), increased water scarcity on farm (x̄ = 3.45), high incidences of pest and diseases (x̄ = 3.29), and increased rate of erosion/flooding (x̄ = 3.50) amongst others. The study strongly recommends that the extension services should be strengthened so as to pay farmers regular visits to ascertain their challenges on the effects of climate variability and know where to assist them.","PeriodicalId":253942,"journal":{"name":"Research Journal of Agricultural Economics and Development","volume":" 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680884","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 methodology adopted in the research is linear regression with the application of the Ordinary Least Squares (OLS) Technique. The E-views 10 was the econometric software used for the research. The major findings of the study reveal that agricultural output contributes negatively and insignificantly to economic growth, government agricultural expenditures contribute negatively and insignificantly to economic growth, rainfall contributes negatively and insignificantly to economic growth and foreign direct investment in the agricultural sector contributes negatively and insignificantly to economic growth. It is therefore the recommendation of this paper that the government of Nigeria should encourage farmers by giving soft loans for agricultural activities. This will help farmers meet with financial needs in terms of purchasing some seeds, hiring machines, etc. thereby boosting massive agricultural production in Nigeria.","PeriodicalId":253942,"journal":{"name":"Research Journal of Agricultural Economics and Development","volume":"24 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141017116","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}

A four-stage sampling procedure was used in the collection of primary data with purposive selection of two agricultural development programme zones in Oyo State of Nigeria. 150 respondents were eventually used for the study. Structured questionnaires and interview schedules were used to collect data. Data were analyzed using descriptive statistics and Shapley decomposition approach. Age and household size of women were 35.5±1.06 years and 8.0±0.59 persons, respectively. Most respondents (88.0%) were married and 43.3% were farmers with income of N24,196.76±11,897.90 per month. Sources that largely explain inequality were primary occupation (0.5551), farm size (0.2523) and household assets (0.0766) and the relative contributions of these factors sum up to 80%. Total inequality computed by the Gini index was 0.2206 and it implies that the contribution of the predicted residual term to income inequality in this case was 22.06%.The marginal contribution of the estimated income sources of the weighted mean with no negative values from level 1 to 12 were primary occupation, educational level, workers per household, number of assets and location with weighted marginal contribution of 0.0125, 0.0120, 0.0105, 0.0071 and 0.0053 respectively. Narrowing the gap between those at the top and the bottom of income distribution will reduce inequality in the households and the nation at large and that is the more reason this study needs attention because within group components overwhelmingly accounted for inequality compared to the between group components. The role of spatial inequality and policies that encourage entrepreneurship training and non-formal education for women in rural areas would be inequality reducing, and would tend to be more effective if additional policy instruments are used to target other sources of measured income inequality.","PeriodicalId":253942,"journal":{"name":"Research Journal of Agricultural Economics and Development","volume":"53 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140699510","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}

Purposive and proportionate random sampling techniques were used to select 121 hot pepper farmers from whom the data was collected using a structured questionnaire. The data was analyzed using descriptive statistics, gross margin analysis, and stochastic frontier production function model. The result of the study shows that hot pepper production activity is dominated by male (99.2%) and married (95.0%) farmers whom are middle aged (Mean = 39 year) and most of them (about 53%) have household size of 1-10 persons, and an average farming experience of 13 years with a farm size average of 1.5 hectares. Majority of the hot pepper producers are engaged in its production for income generation while only few among them have access to credits. The result of the gross margin analysis (GM) shows that hot pepper farmers incurred total variable cost (TVC) of NGN138,703.6, and a return of NGN164,513.4 that yielded the profit of NGN25,809.8 per hectare of production and a return on investment of 1.28. The average technical efficiency (TE) of the farmers was found to be 80% among hot pepper farmers in the study area. Moreover the result of the frontier analysis shows that seed, labor and fertilizer are significant inputs determining hot pepper output. In addition to that inefficiency components of the frontier analysis revealed education, access to extension service, cooperative membership, Years of farming experience, farm size, and household size to be the significant determinants of efficiency of hot pepper production in the study area. The result also revealed that farmers in the study area are faced with major challenges of high costs of production inputs and problems of pests and diseases.","PeriodicalId":253942,"journal":{"name":"Research Journal of Agricultural Economics and Development","volume":"66 47","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139448830","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}

Multi-stage sampling procedure was deployed to select and interview 366 livestock marketers. Descriptive statistics, likert scale and binary logistic regression model were used to analyze data collected. Majority (76.5%) of the livestock marketers were found to be engaged in cashless transactions. The livestock marketing in the study area is predominantly by male (100%) and married (96.45%) marketers of which most of them have some level of formal education ranging from primary (40.71%), secondary (19.94%) and tertiary education (28.43%). They have an average age of 47 years with an average experience of 21 years of marketing activities. Majority (88.25%) of them were also found to have annual income of 100,000 – 1,080,000 naira. Results further show that cashless transactions were effective only in animal selling transactions (M=3.079) and animal purchase transaction activity (M=2.349), among various livestock marketing activities. The result findings also revealed level of education (p<0.01), income of the marketers (p<0.05), cooperative members (p<0.01), and mobile phone ownership (p<0.01) to be the statistical significant factors influencing decision of livestock marketers participation in cashless transaction in the study area. Inadequate cash in circulation (98.09%), poor acceptance of transfer by some marketers (96.99%) and uncertainty of transaction success (96.72%) were major challenges of engagement in cashless transactions in the study area. It can therefore be recommended that mitigating challenges and improving contributing factors will enhance cashless transaction effectiveness in Livestock marketing activities.","PeriodicalId":253942,"journal":{"name":"Research Journal of Agricultural Economics and Development","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139277096","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}

Primary data from the 330 copies of the questionnaire were distributed to rural farmers in the study area. Data obtained were analyzed using descriptive statistics, spearman correlation and paired sample T-Test to test the formulated hypotheses of the study at the 5% level. Results from the data analyzed shows that the correlation matrix between the variables (cooperative marketing, cooperative credit extension and cooperative farm input supply) revealed positive coefficient values of 0.111, 0.151 and 0.372 respectively. The implication of this is that there exists a significant positive relationship between the dependent and independent variables in the study area. This also explains that cooperative marketing, cooperative credit extension and cooperative farm input supply will help in reducing poverty in the study area. The study recommended that government should improve on the road infrastructure in the rural areas to create easy transportation of agricultural produce to city centers to further enhance rural income, government and relevant agencies are advised to make prompt and low interest rate credit facility available for farm business and should provide farmers with the needed input to boost farm business which can aid employment creation and also provide the farmers with the technical know-how through trainings and seminars on the use of implements/inputs that can be helpful to their farming.","PeriodicalId":253942,"journal":{"name":"Research Journal of Agricultural Economics and Development","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131657472","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}
