A multistage sampling technique was used to select 390 cocoa farmers from three zones where cocoa is commercially grown in Nigeria. Separate stochastic frontier models were estimated for farmers in Kwara, Edo and Ondo States, along with a metafrontier model to obtain alternative estimates for the technical efficiencies of farmers in the different states. Subsequently, a Tobit model was used to access the factors influencing cocoa production in the study area. Results revealed that, the average technical efficiency level was 0.685 for the pooled sample, 0.506, 0.837 and 0.713 for Kwara, Edo and Ondo States respectively, suggesting that there is substantial scope to improve cocoa production in Nigeria. The mean MTR values of 0.506, 0.837 and 0.712 for Kwara, Edo and Ondo States respectively, implied that Edo State was more technically efficient than other states in the study area.  The mean technology gap ratio (TGR) value of 84.3% indicated that, on the average, the cocoa farmers in the study areas would have to close a gap of about 15.7% in order for them to be technically efficient. The study recommended that cocoa farmers in Edo and Ondo States could improve their technical efficiency through a better management using the available technologies and resources while intervention to raise technology that will help close the gap between the regional frontier curve and the global frontier curve through raising and distributing disease resistant and high yielding cocoa seedlings to the farmers should be adopted in Kwara State.","PeriodicalId":222396,"journal":{"name":"Research on World Agricultural Economy","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124140262","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}

Taking advantage of the resource advantage of soil rich in selenium in Taoyuan County [1], it promotes high-yield cultivation and assembly technology of selenium-rich rice and rapeseed rotation in one-season rice area, optimizing the aggregate structure of the soil, improving the soil ecology and reducing the content of heavy metals in the soil [2], laying the foundation for the continuous increase in agricultural efficiency and farmers' income. Through rice and rapeseed rotation, the overwintering base of rice field borers are reduced, and the incidence of pests and diseases in the coming year is effectively reduced [3]. The implementation of supporting technologies for rice-rapeseed rotation cropping and the widespread promotion of high-quality varieties and planting techniques have improved the level of farmers’ planting. After one season of rice harvesting, most of the farmland is left unused. Using winter fallow fields to develop selenium-enriched rapeseed industry can actually increase the income of farmers.","PeriodicalId":222396,"journal":{"name":"Research on World Agricultural Economy","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129177477","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 total of 120 day-old broiler chickens from a reputable and disease free farm were used for this study. There were four treatments, each having thirty broiler birds replicated thrice with ten broiler birds per replicate using a Completely Randomized Design (CRD). The broiler birds were offered feed and water ad libitum. The growth parameters were taken on weekly basis. Carcass evaluation was carried out at the end of the trial. One bird per replicate was randomly selected, fasted over-night and slaughtered by severing the jugular vein. After scalding in warm water for about a minute, the feathers were manually plucked, each bird was cut into parts for carcass evaluation. The relative weights of the cut parts were as a percentage of dressed weight. The internal organs, such as heart, kidney, gizzard/proventriculus were all weighed separately and recorded using electric micrometer (3000g weighing gauge). The findings from this study showed that all the carcass parameters considered showed significant differences (p<0.05). Birds fed diet 3 gave the best live weight, slaughtered weight, defeathered weight, dressed weight and commensurate cut-parts. Soybean (whether cake or full-fat) demonstrate superiority over groundnut cake and cashew nut cake. Birds fed diet 3 gave the highest value of thigh, breast -cut, drumstick and wings, while birds fed diets 2, 1 and 4 gave less. The organ proportions of broiler chickens fed different dietary plant sources have all the parameters significantly difference (p<0.05), except the lungs though without any definite pattern. Average weight gain and feed conversion ratio were better (p<0.05) among birds fed diet 2, and 3. Cost benefits analysis per kilogram in naira terms for birds fed different plant protein sources in a sorghum-based diets were significant (p<0.05) among treatment levels. Least cost per kg feed was obtained in diet 1 (p<0.05). Cost of weight gained was (p<0.05) low in T1. Cost of feed consumed was low for diet T1 and T3. Revenue, gross margin and cost benefit ratio estimated were found to high (p<0.05) among T2 and T3. Broiler chickens fed diet 3 gave the best parameters. The actual contributions of the experiment, is to alternatively replace corn with sorghum completely at least cost with optimum performance.","PeriodicalId":222396,"journal":{"name":"Research on World Agricultural Economy","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131561560","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 specific objectives of the study were to describe the socioeconomic characteristics of the respondent, ascertain the extent of use of improved goat production technologies, determine factors influencing use of improved goat production technologies and identify the constraint to access and use of improved goat production technologies in the study area. A multi-stage random sampling technique was adopted in selecting the sample size 120 respondents. Data for the study were collected through the use of questionnaire. The data collected for the study were analysed with both descriptive and inferential statistics. The result of the socioeconomic characteristics revealed the mean age of the respondents was 43 years, majority 69.16% of the respondents were married, about 45% had secondary education, a mean household size of 6 persons, majority 66.67% were farmers, mean years of arming experience at 5.7 years, mean income of #102,000, mean farm size of 11 goats and majority (78.33%) of respondents were non- members of cooperative societies. The result on extent of use of improved goat production technologies, revealed that the respondents highly used most of improved goat production technologies as affirmed with the grand mean of = 3.20. On constraint to use of improved goat production technologies, all the respondents 100% agreed that lack of access to credit was a constraint to use, 100% agrees on lack of credibility from source of technological information, 99.2% agreed that they were afraid of taking risk, 93.3% agreed on difficulty in technology application among others. The OLS regression estimates of the influence of socioeconomic characteristics the respondents on the use of improved goat production technologies in the study area, revealed that age at 10%, education at 1%, household size at 1%, farming experience at 1%, farm size at 1%, income at 1% and access to credit at 5% were the determinants of use of improved goat production technologies in the study area and the null hypotheses rejected. In conclusion, greater use of available improved technologies will promote productivity, and therefore there is need for proper sensitization and awareness by relevant agencies.

Objectives of the study were to determine the entrepreneurship skills available that are utilized for empowering women in cocoyam production and determine the extension strategies for empowering women in cocoyam production. The hypothesis of the study states that there is no significant mean difference between the available entrepreneurship skills and strategies utilized for empowering women in cocoyam production. Questionnaire was the instrument for data collection constructed on a 4-point measuring scale which has (  as the cut of point. Instrument was validated by peer review of two experts in agricultural extension and statistics. The reliability was achieved by subjecting the data collected from pre-survey to Cronbach’s Alpha which yield a reliability co-efficient rα = 0.83 which affirmed high reliability index. Multi-stage simple probability and disproportionate sampling technique was used to select sample size of 250. In Abia, 100 women cocoyam farmers were sampled while 150 were sampled from Imo State. The instrument was administered and retrieved by the help of research assistants such as extension agents and executives of women development union in the sampled areas. The data collected were analyzed using descriptive statistics of frequency, mean and inferential statistics as t-test at 0.05 level of significance. The findings revealed that entrepreneurship skills were available in empowering women with the pooled mean scores of (  for Abia and (  for Imo State. The Imo women were better than Abia cocoyam farmers. It was also indicated that strategies for empowering women cocoyam farmers were used more in Imo State with 2  than Abia State 1 . The hypothesis of no significant mean difference was not rejected because t = -0.003 at P ≥ 0.05 indicated no mean difference between the strategies utilized in Abia and Imo State for empowering women on entrepreneurship skills in cocoyam production. It was concluded that women cocoyam farmers were less empowered and had less access to land, fund and extension services in both Imo and Abia State. But the Imo cocoyam farmers were marginally better than their Abia women cocoyam farmers counterpart on the strategies used on empowering women on entrepreneurship skills in cocoyam production. It was concluded that cocoyam farmers were less empowered on entrepreneurship skills, hence, they had less access to land, fund and extension services.

Using a survey design, a two-stage sampling procedure was used to select 81 males and 39 females from a population of 229 fish farmers. Data were presented using descriptive statistics and analyzed with budgetary technique and gender gap ratios. Key result shows that the men and youths had direct access to land through inheritance and purchase while the women (61%) accessed land through a family relation. The men and male youths performed majority of the gender roles involved in preparation of ponds, fingerlings stocking, fish management and post-harvest activities while the women and female youths were actively involved in fish management, liming and grading. Economic indicators show that the men and youths have a higher return on investment than the women implying that such power differences still exist. Hence, it is recommended that women should be organized in groups for empowerment.
