An evaluation of farmers’ adoption of yam minisett technology in Agricultural Zone 3, Rivers State, Nigeria

The study investigated farmers’ adoption of yam minisett technology in Agricultural Zone 3, Rivers State, Nigeria. The objectives of the study were to examine farmers’ level of awareness of yam minisett technology in the study area, to access the extent of adoption of yam minisett production technique in the study area, examine the constraints to adoption of yam minisett technology in the study area and to determine the influence of yam minisett utilization on the yield of yam in the study area. The study adopted a survey research design. A sample of 360 farmers was selected using random sampling technique. Structured questionnaire was used for data collection. Frequency, percentages, mean and standard deviation were used to analyze and realize the objectives of the study. The findings of the study reveal that farmers in the study area had low awareness level about the yam minisett technology and adoption of the yam minisett technology. Cost of innovations, lack of technical efficiency and low sprouting rate of minisetts, poor extension delivery service and the top-down extension approach which does not take cognizance of farmers-identified production problems, lack of youth participation and involvement in farming (yam production) as a result of search for white-collar jobs, socio-economic characteristics such as educational level or background, and lack of land to commercially produce in quantity, among others are constraints to the adoption of yam minisett technology in the study area. It was recommended that the farmers should be encouraged to engage in training and to seek financial assistance in order to overcome the problem of scarcity and high cost of inputs.

Yam (Dioscorea spp.) cultivation has the potentials to greatly contribute to poverty alleviation and food security, in Cameroon. The full production potentials of yams have not been exploited, leaving Cameroon with an annual production of 648,407 metric tons (MT) at the sixth position, among the six countries of the West African yam zone, with 67.3 million MT. This review highlights research gaps in the yam production chain, which can be exploited to enhance production in the country. Subsistent yam cultivation takes place in all five agro-ecological zones of the country. Although with many fluctuations, yield and production quantities have recorded a marginal net increase, since 1961. Cameroon has nine cultivated and 17 wild species, exploited by Baka pigmies for food, but there is no established genebank, thereby exposing the genotypes to genetic erosion. Cultivated species are both indigenous and exotic, and traditional seed systems (sorting, junking, and milking) are exploited for seed procurement. Minisett technology is also gaining grounds. Yam processing is very limited, and, coupled with poor conservation facilities, contributes to elevated post-harvest losses. The yam marketing system is poorly organized, and hinders farmers from reaping optimum benefit from the activity. Other major constraints to yam production include high labour demand, pests and diseases, absence of improved seeds and research neglect. There is the need for concerted efforts involving all stake holders in the yam production chain to enhance yam production in Cameroon. Key words: Review, yam (Dioscorea spp.), production, Cameroon. &nbsp

Subjective Household Income Risks And Schooling Investment In Rural India

This study assesses the impact of adoption of improved seed yam technology (the minisett technology) on yam yields and the income of smallholder farmers in the northwest region of Cameroon. This technology has the potential to increase yam yields by a factor of 2 to 3 compared to traditional techniques, however, adoption by smallholder farmers in Cameroon has so far been low. Survey data was collected from a total of 394 randomly sampled farmers in three of the five administrative divisions of the northwest region. Of this total sample a sub-sample of data from 274 farmers who had been exposed to the technology was analyzed using propensity score matching (PSM) and employing a variety of different matching algorithms that take into account counterfactuals and potential impact. PSM is a quasi-experimental research design which was adopted because it is known to address problems of selection bias resulting from sampling and selfselection issues. The results show that the adoption of the minisett technology has a positive and significant (p

A Tobit Analysis of Propensity to Discontinue Adoption of Yam Minisett Technology among Farmers in Anambra State, Nigeria

This study analyzed farmers’ propensity to discontinue adoption of yam minisett technology in Anambra State, Nigeria. Data were collected in 2015 with validated questionnaire from 134 proportionately and randomly selected yam farmers. Data collected were analyzed using the Tobit model. Results of the estimation showed that significant variables leading to discontinuance of adopted yam minisett technology were extension visit, participation in extension related workshops, feedback provision, input availability, and perception of yield. Foremost among these factors were extension visits and participated in extension related workshops which therefore should be sustained after farmers have adopted a technology.

Factors limiting the yam minisett technique adoption: A review

The yam minisett technique was developed to overcome the scarcity of seed yams, and has been introduced to farmers more than any other scientifically improved yam propagation method. However, the adoption rate of this technique has not significantly improved over the years. This paper presents an overview of the factors contributing to the low adoption rate of the technique since its deployment in Nigeria. Three main classes of factors influencing the adoption of the yam minisett technology are presented; informational factors, technical factors and economic factors. Among the informational factors, low rate of extension contact coupled with low membership of social groups has negative impacts on the level of awareness of the technology. Issues relating to technical and economic limitations are the major challenges faced by the minisett technique adopters. Among these, the low survival and sprouting rate of minisetts, high labour costs and low level of capital are of utmost importance.

ADOPTION OF YAM MINISETT TECHNOLOGY IN DELTA STATE, NIGERIA

Yam minisett technology provides seed yams repidly. It is designed to alleviate the problem of seed yams scarcity, which has been identified as a major constraint to increased yam production. This study examined the adoption of the technology by farmers in Delta State, Nigeria. A random sampling technique was employed in the selection of respondents. A sample size of 240 yam farmers participated in the sutdy. Data were collected through the use of structured interview schedule. Both descriptivew and inferential statistics were used in analyzing data generated by the study. Results of the sutdy reveal that respondents had moderate awareness of yam minisett technology with an overall awareness percentage of 46%. The study also found an overall mean adoption score of 2.24, which indicates a general low adoption of the technology with an overall awareness percentage of 46%. The study also found an overall mean adoption score of 2.24, which indicates a general low adoption of the technology by the farmers. Application of minisett dust with adoption score of 2.05 was the least adopted yam minisett technology item, while cutting into minisett was the most adopted with adoption score of 2.79. The study found a significant relationship between some farmers’ socioeconomic characteristic and adoption of yam minisett technology. Reommendations of the study include that more awareness on the technology should be created among the farmers by the relevant agency through the use of extensions campoaigns, demonstrations and small plot adoption trials (SPAT). Also, farm credit should be granted to yeam farmers through the State Government's Mirco Credit Scheme (SGMCS) to enhance their adoption of the technology.

Factors affecting proportions of land allocated to the mini-sett technology by yam producers in Northern Ghana

The study investigated factors affecting proportions of land allocated to the yam mini-sett technology among 120 randomly selected farmers in Northern Ghana. About 41% of the farmers allocated about 33% of their yam land to the technology. Results from the Tobit regression model suggest that the dissemination of the technology must also target farmers who are non-natives, household heads, less experienced, have large household sizes, and record low yields. The process must consider the type of cropping systems, seed yam production and collaborations with non-formal educational programs. Training must promote positive perception about the technology and proliferation of off-farm income generating activities. Key words: Adoption, Northern Ghana, Tobit, yam mini-sett.

Socio-economic Determinants of the Adoption of Yam Minisett Technology in the Middle Belt Region of Nigeria

The paper assessed the socio-economic determinants of adoption of yam minisett technology in the middle belt region of Nigeria; where 120 farmers were sampled through multi-stage random technique from six villages in two Local Government Areas of Kogi and Benue States. Data collected by structured interview were analyzed using descriptive statistics such as frequency counts, percentages and means; and probit regression model. Results showed that 98.33 percent of farmers were aware of the technology while only 9.32 percent adopted the technology. The probit analysis indicated that age of the farmers, farm size, years of farming experience, amount of credit available and frequency of extension contacts were positively related to adoption and would probably increase adoption of the improved yam minisett technology. There is need to increase availability of credit, fertilizers and yam minisett dust, as well as improve extension services in the study area.

Economic Analysis of Commercial Seed Yam Production Systems in the Sub-humid Ecologies of the River Niger

Published studies to date have suggested that seed-yam (Dioscorea rotundata) production in Nigeria using minisett (∼0.025 kg) technology or an adapted form of the technology using larger setts (0.08 to 0.1 kg) was not profitable. But these studies were often conducted under artificial conditions where labor inputs may have been inflated. This paper describes the results of a questionnaire-based survey designed to explore the economic performance of seed-yam producers in the Ilushi hinterland area of Nigeria, along the western bank of the River Niger. It is the first economic study of this important source of seed yam. Farmers in this area specialize in seed-yam production via two techniques: the use of small whole tubers (0.05 to 0.1 kg) and setts (cut pieces of tuber) of 0.12 to 0.15 kg. Results suggest that seed-yam production is profitable in the area using both systems, with gross margins (revenue – costs) of between Naira 23,395 and 61,375/ha (or US$175 to $458/ha).

Effect of chemical and time of cutting of milked yam Minisetts on storability and Performance of Minisetts

The milked yam minisett technology was developed as a rapid method of seed yam multiplication with an advantage of higher, early and uniform sprouting of setts compared to the normal minisett technology. A study was carried out at the Teaching and Research Farm as well as AgronomyProcessing and Storage house of the University of Agriculture, Makurdi to test the effect of chemicals and time of cutting of milked yam minisetts on storability and performance of setts in the field. The setts were milked in September and October 2006 and same time in 2007, treated with chemicals and reburied. They were harvested in December and stored for 5 months before planting them out in the field. Results showed that setts milked and cut on October 30 each year recorded the greatest rotting of setts in the month of May of the following year before plantingthem out in the field, followed by setts milked and cut on September 30. The setts milked and cut on October 15 each year, stored better than the others and had the highest percentage germination in storage. The best treatment among setts milked and cut on September 30 (Monceren)yielded more than the best treatment among setts cut on October 15 (Monceren and rizolex) by about 73.6% and the best treatment cut on October 30 (Monceren) by about 194.6%. Also the best treatment among setts milked and cut on October 15 yielded more than the best treatmentamong setts milked and cut on October 30 by about 69.7%. So in terms of the storability of setts, the setts milked and cut on October 15 were the best while setts milked and cut on September 30 that survived storage performed best in the field. The best time to milk and cut the setts is between the end of September and mid October. Monceren fungicide performed better than all the other chemicals.

Evaluation of factors driving the adoption of yam minisett technology by farmers in Abia State, Nigeria.

The study was carried out to evaluate the socio-economic factors influencing adoption of yam minisett technology by farmers in Abia State. 120 farmers were purposively selected from the three agricultural zones of the state namely Aba, Ohafia and Umuahia respectively. Primary data for the study were collected on respondents' socioeconomic characteristics, use of minisett technology and constraints militating the adoption of yam minisett technology using structured questionnaire. Data were analyzed using descriptive statistics such as frequency count and percentages. Ordinary least square regression analysis of the double log form was usedto determine the socioeconomic factors influencing adoption of yam minisett technology by the respondent farmers. Results showed that farmers fall within the age brackets of 40-50 years. Farm size (t= 2.99),Educational level (t= 2.75) and credit availability (t = 3.03) are positive and significant. (P=0.05) The problems farmers encountered included high cost inputs, and unavailability of credit facility. Others are procurement of land and insufficient extension services in that order. Conclusion is drawn that farm size, educational level and credit availability are the socio-economic factors influencing the adoption of yam minisett technology. It is then recommended that Government should evolve positive policies which will ensure that soft loans are given to genuine farmers at minimal interest rate and the farmers should be monitored to properly use the loan. This will enable them increase their farm size, procure inputs, adopt innovations and consequently improve agricultural production.Keywords: Socio-economic, Adoption, YamMinisett,

Factors influencing yam minisett technology adoption by farmers in Enugu state Nigeria

The study was designed to examine the factors influencing yam minisett adoption by farmers in Enugu state, Nigeria. A multi-stage random sampling technique was used to select 96 yam growing farmers in the state. Interview schedules were used to elicit information from the respondents. Data were analysed using statistical tools like frequency, percentages, means and probit model. The results revealed high level of awareness (93.75%) and high rate of adoption (88.74%) of the technology by the farmers. However, further investigation showed that the extent of adoption was low (24.71%). The probit results indicated that age (P=0.05), farm size (P = 0.01), educational status (P = 0.10), membership of farmers' association (cooperatives (P = -0.01), frequency of extension contact (P = 0.01) and access to credit (P = 0.10) were the variables that significantly influenced adoption of the technology. High cost of labour (82%), scarcity/ high cost of fertilizer (81%), scarcity of minisett dust (70%) and lack of loan (57%) were among others, the problems encountered by the farmers in adopting the technology. The study recommended that research and extension should step up promotion of the technology by ensuring that the complementary input are made available to the farmers to enhance adoption of the technology. The farmers should also be encouraged to increase their farm size and join cooperative/farmers association to have easy access to credits, information, input to enable them adopt the technology to increase their seed yam production in the State.Keywords: yam, minisett, adoption, farmers, labour cost, credit

Availability Of Improved Crop Production Practices In Aguata Area Of Anambra State, Nigeria

The study focused on availability of improved crop production practices in Aguata area of Anambra State, Nigeria. A structured questionnaire was administered to one hundred randomly selected respondents from twenty communities in five local government areas. Data analysis was by the use of frequency distribution, percentages, and mean scores. Findings of the study revealed that that the following improved crop production practices were available to the respondents: adequate crop spacing, optimum plant population, seed dressing, use of fertilizer, use of insecticides, regular weeding, adequate disease control measures, timeliness of planting, yam minisett technology, improved maize varieties, improved cassava varieties, dry season vegetables. Herbicide use was however identified as less available.

Socio-Economic Characteristics As Correlates Of Adoption Among Yam Farmers In Rural Ikwerre Areas Of Rivers State, Nigeria

This study assessed the correlation between socio-economic characteristics of yam farmers and adoption of yam minisett technology. It was carried out in the Ikwerre rural areas of Rivers State, Nigeria. The sample size of the study is made up of 252 yam farmers who were randomly sampled. Interview schedule was used for data collection. Data were analyzed with the use of percentages and Pearson Product- Moment Correlation Coefficient (r). Results indicate that complete adoption is as low as 18.6%. Results of the r-values of socio-economic characteristics of yam farmers and adoption at 0.05 level of significance shows that age (r=-0.1149) and farming experience (r=-0.0897) were negative, very low and not significant. Income (r= 0.5540), yam farm size (r=0.5982) and extension contact (r=0.5851) gave positive, moderate and significant correlation. Education (r=0.7658) however, gave a positive, very strong and significant correlation with adoption. In view of the above results, it is recommended that extension efforts concentrated around middle age yam farmers who have higher: income, farm size, extension contact and education will yield a better adoption among yam farmers in this study areas.
