This study principally assessed the influence of socio-economic factors on uptake of rhizobia inoculant technology in the Northern Region. Sample sizes of 210 respondents were interviewed using questionnaires. Secondary data was also collected for the study and the results analyzed. Simple random and purposive sampling techniques were used in selecting respondents. The data were analyzed using appropriate descriptive statistics and multiple linear regressions. The linear multiple regression model was fitted to estimate the factors that are perceived to influence or predicts farmers Uptake of Rhizobia inoculant. The adjusted coefficient of determination (R2) of 0.350 suggests that, 35.0% of the variation of farmers’ uptake of rhizobia inoculant can be explained by the model. On the other hand, the linear regression model revealed nine variables had significantly influence on farmers’ uptake of rhizobia inoculant in the study area, these includes; Years of inoculant introduction, Sex, Demonstration plot, Age, Video show, Marital Status, Farm size, Farming Experience, Radio program and Educational level at 5.0% significant level.

The agricultural sector faces a challenge of poor soil fertility and food insecurity in Africa,1 with high cost of inorganic fertilizer2 and poor economic status of most smallholder farmers. Farmers in Africa are unable to inorganic fertility, agricultural research have developed rhizobia inoculants as a cost effective substitute of improving low soil fertility,3 as well as boosting yield of soybeans.4
However, the use of rhizobium inoculants have been an effective agronomic practice for ensuring adequate N-nutrition of legumes, compared with the application of N-fertilizer.5
The use of rhizobia inoculant boosts legumes production and improves soil fertility at a cheaper cost,6 Notwithstanding its potential to addressing low Nitrogen in soil and its cost effectiveness, adoption of rhizobia inoculants by farmers still remains low.7 Whiles, the country is still far from realizing wide-scale use of rhizobia inoculant among farmers. To achieve realized wide-scale use of rhizobia inoculant among farmers, it would be important to understand the factors which influence uptake or adoption of agricultural technology among end users. However, leading researchers have established a relationship between socio-economic characteristics and technology adoption. For instance, Lavison8 established that farm size can affect and in turn be affected by the other factors influencing of technology adoption. Also, human capital of the farmer is assumed to have a significant influence on farmers’ decision to adopt new technologies,9 Education of the farmer has been noted to have a positive influence on farmers’ decision to adopt new technology. Education level of a farmer increases his/her ability to obtain; process and use information relevant to adoption of a new technology. 8,10
Age is seen as another determinant of adoption of innovation. With older farmers assumed to have gained knowledge and experience over time and are better able to evaluate technology information than younger farmers. 11 Bonabana &Wabbi,12 suggested that sex is a determinant of agricultural technology adoption. Since the head of most farming household is the primary decision maker and men have more access to and control over important production resources than women because of socio-cultural values and norms.10
Thus, all these scholars’ points to the fact that farmers’ socio-economics factors have influence on uptake of technology. Hence, this paper aims to determine how farmers’ socio-economics factors would influence uptake of rhizobia inoculant technology in the Northern Region by examining its effects with respect to farmers intensity to use rhizobia inoculant technology in farms and draw conclusions that might help in developing interventions to encourage adoption of rhizobia inoculant technology
The study will be carried out in the northern region of Ghana. Primary data on socio-economic factors that influence farmers’ uptake of rhizobia inoculant technology in the Northern Region were collected using questionnaire and key informant interviews (among legume farmers) to 210 respondents. Secondary data were gathered from records of SARI, IITA as well as reviews of journals and library materials. The survey employed purposive and simple random sampling techniques in selecting the sample for the study, in selecting the districts for the study, purposive sampling technique were employed and two (2) districts out of 27 districts in the Northern Region were selected. These districts were, namely Tolon District and Savelugu Municipality.
The selection is because of the operations of Savannah Agricultural Research Institutes (SARI) and International Institute of Tropical Agriculture (IITA) within these districts having major demonstrations field and community outreach. Six communities were randomly selected from Savelugu Municipality and Tolon district respectively. From the list of legume farmers from each community sampled, the lottery method of random sampling technique were used to sample 35 legume farmers from each of the six communities to form a sample size of 210 in the Northern Region of Ghana. Data was analysed using frequencies and percentage as well as multiples linear regression.
Demographic profile of farmers
The survey results (Table 1) show that majority of legume farmers (73.3 %) were males; with 26.7 percent of legume farmers being females. Although females form the least group in the survey, they play several roles such as planting, harvesting, shelling of legumes etc. However, much of what the women do on the farm is, mostly considered as family labour and this could accounts for the small number of female farmers (26.7%) in the study area. On age of respondents, the results revealed that, 23.8 percent of the farmers were below the age 30, with 5.7 percent being above 60 years. However, 37.6 percent of farmers were between 30 and 45 years, whiles 32.9% of the respondents were between the age 46 and 60 (table 1.0) as seen the table below. The analysis on marital status of respondents indicates that, majority of farmers (78.1%) interviewed were married, while very few (5.2%) are single (never married) and 10 percent and 6.7 percent divorcees and windows respectively. With educational status of respondents, few farmers had Junior High education (9.0%), primary education were 25.2 percent and 12.4 percent had secondary education. However, 53.3 percent had no-formal education. With, none of the respondent having tertiary. These results indicate that majority of the farmers were illiterates with no formal education. Though, Higher education status of a farmer increases their ability to process and use information disseminated to them on agricultural innovation.8

However, in line with the findings, it might be difficult for illiterate’s farmers to properly understand information disseminated to them by promoters of rhizobium inoculant in order to make proper judgment on whether to adopt or not. With regard to farming experience, the results shows that, 19.5 percent of the respondents had less than 5 years’ experience of legume production, with 28.1% had between 5-10 years’ experience of legume production and 52.4 percent had more than 10 years’ experience of legume production. Some researchers suggest that experience in a particular is relevant in achieving results over time, (Fiedler, 2007; McCall et al. 2004). Thus, this suggests that since, most legume farmers had a much farming experience in legume production, adoption of rhizobium inoculant is likely to occur after these projects are over.
Relationship between farmers uptake rhizobia inoculant and socio-economic factors
Table 1.9 demonstrates that Adjusted R Square for this model is 0.350 which indicates 35.0% of the variation on uptake of rhizobia inoculant (dependent variable), uptake of rhizobia inoculant (dependent variable) can be explained by Years of inoculant introduction, Sex, Demonstration plot, Age, Video show, Marital Status, Farm size, Farming Experience, Radio program and Educational level (independent variables) (Table 2).

ANOVA analysis
According to Table 1.10, the F-value of 12.243 is highly significant at 5%. This indicates that the overall regression model with these independent variables (Years of inoculant introduction, Sex, Demonstration plot, Age, Video show, Marital Status, Farm size, Farming Experience, Radio program and Educational level) can well explain the variation of the dependent variable (Uptake of Rhizobia inoculant) (Table 3).

Relationship between farmers uptake rhizobia inoculant and socio-economic factors
An equation is formed based on Table 1.11 below to determine the statistical significance of each of the independent variables (Years of inoculant introduction, Sex, Demonstration plot, Age, Video show, Marital Status, Farm size, Farming Experience, Radio program and Educational level) on the dependent variable (Uptake of Rhizobia inoculant). A linear multiple regression model was fitted to estimate the factors that are perceived to influence or predicts farmers Uptake of Rhizobia inoculant. The adjusted coefficient of determination (R2) of 0.350 suggests that, 35.0% of the variation of farmers’ uptake of rhizobia inoculant can be explained by the model. The result from the linear regression model revealed nine variables had significantly influence on farmers’ uptake of rhizobia inoculant in the study area, which are Years of inoculant introduction, Sex, Demonstration plot, Age, Video show, Marital Status, Farm size, Farming Experience, Radio program and Educational level at 5.0% significant level.
Sex
Sex of respondents in the study area was found to have a positive effect on inoculant use with a coefficient of 0.233. This means that women had a higher probability of inoculant use as compared to their male counterparts. Thus, women have a 0.233 higher chance of inoculant use compared to their male counterparts. This finding is in line with Obisesan (2014), studies which revealed a positive influence of sex on technology adoption.
Age
Age of respondents in the study area was found to have positive influence on the intensity of inoculant uptake with a coefficient of 0.309. This implies that when age increases by one year, the probability that a farmer uses soybean inoculant increase by 0.309 keeping all things constant. This result confirms with Kariyasa and Dewi (2011), that age is a determinant of adoption of new technology. Older farmers are assumed to have gained knowledge and experience over time and are better able to evaluate technology information than younger farmers.
Marital status
The study revealed a negative relationship between marital status and uptake of rhizobia inoculant in the study area, with a coefficient of 0.291. This implies that unmarried farmers are more likely to use rhizobia inoculant.
Educational level
Educational level was found to have positive influence on the intensity of inoculant uptake with a coefficient of 0.291. This implies that when a farmer educational status increases by one unit, the probability that a farmer uses soybean inoculant increase by 0.291 keeping all things constant. This result confirms Lavison,8 assertion that education of the farmer has have a positive influence on farmers’ decision to adopt new technology. Through, increasing their ability to obtain; process and use information relevant to adoption of the new technology.
Farming experience
Farming experience was found to have negative influence on the intensity of inoculant uptake with a coefficient of -.172. This implies that when a farmer educational status decrease by one year, the probability that a farmer uses soybean inoculant decrease by -.172 keeping all things constant. According to Mignouna et al.10 older farmers are assumed to have gained knowledge and experience over time and are better able to evaluate technology information than younger farmers as well as making decision on adoption.
Radio program
The use radio to access information on rhizobia inoculant was found to have positive influence on the intensity of inoculant uptake with a coefficient of 0.270. This implies that when a farmers is expose to information on rhizobia inoculant increase by one unit, the probability that a farmer uses soybean inoculant increase by 0.270 keeping all things constant
Video show
The use video to access information on rhizobia inoculant was found to have negative influence on the intensity of inoculant uptake with a coefficient of -.363. This implies that when a farmers is expose to information on rhizobia inoculant decrease by one unit, the probability that a farmer uses soybean inoculant decrease by -.363 keeping all things constant
Demonstration plot
The use demonstration to access information on rhizobia inoculant was found to have positive influence on the intensity of inoculant uptake with a coefficient of 0.122. This implies that when a farmers is expose to information on rhizobia inoculant increase by one unit, the probability that a farmer uses soybean inoculant increase by 0.122 keeping all things constant
Years of inoculant introduction
The years of inoculant introduction to farmers was found to have negative influence on the intensity of inoculant uptake with a coefficient of -.225. This implies that when years of inoculant introduction to farmers decrease by one year, the probability that a farmer uses soybean inoculant decrease by -.225 keeping all things constant
From the analysis above, nine variables out of ten variables namely; Sex, Age, Marital Status, Educational level, Farming Experience, Radio Program, Video Show, Demonstration plot and Years of inoculant introduction had a joint influence on the dependent variable (Table 4).13–15

In assessing the factors which assessed the influence of socio-economic factors on uptake of rhizobia inoculant technology in the Northern Region. The study results that, there were more males than females farmers in the Northern Region of Ghana. Majority of them are in their middle ages and married. Most farmers had significant experience in farming due to the numbers of years there having. Majority of farmers had no formal education. However, the overall socio-economic factors of farmers have a strong influence on farmer uptake of rhizobia inoculant. However, farm size has no influence on farmer uptake of rhizobia inoculant and for that matter. Farmers with large farm size are generally not in support of rhizobia inoculant usage as this characteristic has no influence on uptake of rhizobia inoculant. Though, years of inoculant introduction to farmers, sex, demonstration plot, age, video show, marital status, farm size, farming experience, radio program and educational level have influence on uptake of rhizobia inoculant. This suggests that focusing on these farmers socio-economic characteristic would aid in realising wide-scale usage of rhizobia inoculant among farmers.
