                  ABSTRACT:
  
This paper presents the review of literatures on agricultural technology adoption, specifically the factors that have the most significant association with technology adoption, continuance and discontinuance. The information were collected from the secondary data available and analyzed.
The farmers’ decision of adoption of technology was strongly influenced by age, gender and literacy of house hold head as the houses with educated, younger, male household head were more reluctant to practice new technologies in agriculture than older people or female household head.
The off farm asset, household wealth index, family size, number of contacts with an extension agent, participation in extension-education activities, membership in social institutions and the presence of farm workers were the most important socio-economic factors influencing the adoption of technology. While continuous use of the technology was influenced by the literacy of the household head, visits by extension agents, farmers’ experience, household land size, membership of farmers groups/cooperatives and off-farm work.
Similarly, the factors affecting the disadoption of technology were increase in price of inputs, lack of credit, lack of extension visits and lack of timely availability of inputs and distance from market. The farmers reported to be discontinuing technology were illiterate and most of them from female household. From the review it is found that extension service, household literacy and availability of credit and inputs and involvement in cooperatives have the biggest impact on technology adoption.

Key words: Technology, Adoption, Continuation, Discontinuation

 III.            INTRODUCTION OR BACKGROUND OF THE STUDY:

Agriculture plays a crucial role in the economy of developing countries, and provides the main source of food and income to their rural populations. Agriculture provides employment opportunities to 66 percent of population and contributes 33 percent share in the GDP of Nepal (MOAD, 2017). Nevertheless, Nepal is struggling to produce an adequate supply of food for its citizens and the reason behind this is the dominance of small and marginal farm holders following traditional and indigenous farming technology which is regarded as low yielding technology. However, there is potential for increasing agricultural productivity as exemplified by the large gap in yield between those of research stations and farmersfields (Paudel and Matsuoka 2009). The adoption of new technologies, such as fertilizer, improved seed, etc. is central to agricultural growth and increasing productivity. Improved agricultural technologies help to boost the performances of the agricultural sector and hence enhance the overall growth of developing countries (Kassie et al. 2011). National Seed Vision (2013-2025) of Nepal states that improved seed can contribute 20-30 percent increment in crop yield. The adoption of high yielding crop varieties by farmers in developing countries has been viewed as the solution to lower incomes in agriculture over the years. Improved seeds and inorganic fertilizers can improve crops’ productivity resulting higher quantities of crops production both for self-consumption and for increased household income (Kassie et al. 2011). Agricultural technologies increase food availability by boosting crop productivity, increasing the supply of food per unit of agricultural land (Feder et al. 1985). Although adoption of new technology is an effective way to increase agriculture production and productivity it is relatively complicate process. Development of a new technology occurs at a particular point in time, while the awareness and use of the technology takes place over a long period of time. The impact or intended purpose of a new technology i.e. productivity growth, can only be felt after adoption and use by the target end users. However, the magnitude of the impact is determined by the rate of adoption, following the diffusion and learning about the technology or innovation over time. Upon introduction of a new technology, it can either be adopted if found to be beneficial and profitable relative to existing alternatives or rejected if found unprofitable. In the agricultural sector, widening of adoption of new technology by all farmers is rare due to the various deterrents to adoption imposed by various economic, social, physical, and technical factors. In all the cases a technology is not continued adoption in some cases the technology are discontinued. The purpose of this study is to analyze the factors influencing farmer’s adoption and continuation or discontinuation of improved agricultural technologies in Nepal.

 IV.            OBJECTIVES:

Broad objective:
  • The main objective of this study is to perform a systematic literature review about the factors influencing adoption of agriculture technologies found in Nepal and other countries.

Specific objectives:
  • To characterize the main technologies used by farmers and factors of major influence in the adoption of those improved technologies
  • Analyze the influence of socioeconomic factors, sources of information, farmer perception and technological factors in the adoption of new technology
  • To determine factors influencing in continuation and discontinuation of agriculture technology.

    V.            LITERATURE REVIEW:

Definition and imp of adoption:

Adoption of innovations refers to the decision to apply an innovation and to continue to use it (Roger and shoemaker, 1971).  An adopter is a farmer who has adopted a component or more of a technology and continued using it, whereas non-adopters are those who have never tried a technology (Doss, 2006). Adoption of new farming technologies is one effective way to increase agricultural productivity (Minten and Barrett, 2008). A study conducted in Mexico showed that adoption of improved maize varieties improves household welfare (Becerril and Abdulai, 2010). Similarly, in sub-Saharan Africa, adoption of improved maize was indicated to have positive outcomes (Alene et al., 2009). Cavatassi et al. (2011) found that agriculture technology permits a reduction in the probability of crop failures and increase grain quality, safeguarding farm income for household food consumption and nutrition. Emiliano Magrini & Mauro Vigani, (2016) found out that use of improved maize varieties and inorganic fertilizers in Tanzania enhanced food availability by increasing maize productivity, which in turn allowed for greater maize production available for local household consumption.

Adoption factors:
There are several factors influencing the rate of adoption, continuation or discontinuation of new technologies in agriculture sector. Rao and Rao (1996) found a positive and significant association between age, farming experience, and training received, socioeconomic status, cropping intensity, aspiration, economic motivation, innovativeness, information source utilization, information source, agent credibility and adoption. There are several examples from the adoption literature (e.g., Becerril and Abdulai 2010; Just and Zilberman 1988; Koundourietal.2006; Uaiene et al, 2009) reveal that adoption decisions are based on risk, uncertainty, input rationing, information imperfections, human capital and social networks. The resource-poor farmers are often reluctant to invest in any untried technology because of their limited resources (cash, labor, time). As economic theory would predict, relatively wealthier (or more resource-endowed) households are better able to cope with production and price risks and consequently are more willing to adopt new technologies than their poorer (or less resource-endowed) counterparts (Bola et al. 2012; Hardaker et al. 2004; Langyintuo and Mungoma 2008). Feder et al. (1985) found that farm size, risk and uncertainty, human capital, labor availability, credit constraints and tenure security were the most important factors determining adoption decisions. Yet some of the concerns raised by Feder et al. (1985), mercer (2004) and Doss (2006) on the need to study the dynamic patterns of adoption remain unanswered. The few recent studies that have properly tracked the dynamics of adoption yield important new insights on learning process, farmer experimentation with new technologies, the impact of changing profitability, social conformity effects, etc( Foster and Rosenzweig, 1995; Cameron 1999; Conley and Udrey, 2001; Moser and Barrett, 2003, 2006).
Moreover, some of the factors that influence the continued use of technology are linked to the experience in using it; the more the farmers know a technology, the more they keep using it. These phenomena generate modeling problems related to self-selection and endogeneity (Doss, 2006).
Human capital endowments, usually captured by family size and composition and education are the main factors influencing the technology adoption and continued use decisions of households.
Family size and composition influence such decisions from both labor supply and consumption demand sides. Availability of labor within the household, as measured in number of adult household members, is taken into account.

Disadoption factor:
Technology adoption is complicated process the households may adopt a technology and will keep on using it. However, apparently the farmers may try a technology and decide not to continue using it also. Rogers (2003) reported two types of reasons for discontinuing a technology use on the part of farmers; that is, replacement discontinuance, where farmers discontinue using the existing technology in order to adopt a superior one, and disenchantment discontinuance, where a decision to discontinue a technology, with or without replacement, is due to dissatisfaction with its performance. There are several reasons behind farmers’ discontinuation of the technology.
Lack of credit and low household income is the reason behind the adoption of both improved maize seeds and inorganic fertilizers in Tanzania. It shows that adopters have a higher level of welfare compared to non-adopters. Both technologies enhanced food availability by increasing maize productivity, which in turn allowed for greater maize production available for local household consumption. Similarly, adopters of improved maize seeds show lower vulnerability to poverty, suggesting that benefits of adoption can last over time and are not confined to a single harvest cycle. On the other hand, inorganic fertilizers have a stronger effect on household resilience, accelerating replenishment of food stocks. The human capital assets (education, skills, and training) of the household head affect the profitability of modern technology, as they reflect unobservable productive characteristics of the decision maker, such as farming skills and entrepreneurship (Carletto et al., 1999).Education increases the ability of farmers to obtain, process, and use information relevant to the technology leading to greater use of new technologies (Wozniak, 1997). However, the literature on the relationship between education and adoption is not definitive, for example Weir and Knight (2000) show that education is associated more with timing of adoption rather than with adoption itself.

 VI.            METHODOLOGY OF THE STUDY:

The study is based on the secondary information collected from the different sources like published journal articles, books, dissertations and working papers on factors affecting technology adoption in agriculture in Nepal and other countries. Web pages were visited and the relevant information were collected. Author's experience in technology adoption in agriculture is also internalized in the paper. Finally, information collected from different sources were analyzed and presented.

VII.            RESULT AND DISCUSSION:

Factors related to adoption and Continuation of Technology:

The farmers’ decision of adoption of technology is strongly influenced by human capital, asset endowment, institutional and policy variables (Motuma Ture et al, 2010). While continuous use of the seed is influenced by the proportion of farmland allocated to maize, literacy of the household head, involvement in off-farm work, visits by extension agents, farmers’ experience, household land size, and fertilizer usage. Ghimire & Huang, (2015) found the positive influence between household wealth index and adoption and intensity of adoption of improved maize varieties. The factors most strongly related to adoption were farmersages, with older farmers being less likely to adopt, possibly because of risk aversion. Education and extension services positively influenced adoption among poorly endowed households, implying that increased awareness and information reduced risk aversion and motivated farmers to adopt new technology. It was similarly reported in Ethiopia that education influences timing of adoption but not whether to adopt an agricultural innovation (Weir and Knight, 2000).
Similarly, membership of farmers groups/cooperatives and off-farm work positively influenced adoption among the subsample of well-endowed households. The distance to market showed a negative impact on adoption and intensity of adoption, the implication is that high production and transaction costs make farmers less competitive in product markets.
Similarly, Ransom et al, (2003) found significant and positive relation between adoptions of improved varieties with khet land area, ethnic group, years of fertilizer use, off-farm income, and contact with extension. Access to extension has been widely reported to positively influence adoption and continued use of agricultural technologies (Feder and Umali, 1993; Knowledge and Bradshaw, 2007). Ghimire, Wen-chi and Shrestha, 2015) revealed that education, extension services and seed access play significant roles in adoption decisions of rice varieties among rural households. Additionally, farm and field characteristic variables such as farm size, endowment of favorable land type (e.g. lowlands), and animal power (e.g. oxen) are the key factors influencing the probability of adoption. Similarly, (Marc Jim Mariano et al., 2012) found that the adoption of certified seed technology and integrated crop management practices in rice were influenced by farmers’ education, machinery ownership, irrigation water supply, capacity-enhancement activities, extension service and profit-oriented behavior. Extension services seem to have the biggest impact on technology adoption. This is supported by Adeogun et al, (2008) found that the main source of technology is through extension personnel and also implied that an inverse relationship exist between the farm size and adoption. Farmer’s age and education, market distance from field and availability of information about input and product as well price were found to be contributing in adoption of technology negatively and positively. (Paswel P. Marenya and Christopher B. Barrett, 2006) found that the size of the farm owned by a household, the value of its livestock, off-farm income, family labor supply, and the educational attainment and gender of the household head all had a significant positive effect on the likelihood of adoption of technology. Seyyed ali noorhosseini-niyaki1 and mohammad sadegh allahyari, (2012) found that family size, number of contacts with an extension agent, participation in extension-education activities, membership in social institutions and the presence of farm workers were the most important socio-economic factors for the adoption of rice-fish farming system.


Factors related to discontinuation of technology:

The important factor affecting discontinuation of technology is the time to time increase in price of inputs like improved seed varieties and fertilizers which are unaffordable to poor farmers.(Motuma Tura et al) identified that high price of seed and fertilizer as reasons for discontinuance of improved maize varieties mainly due to lack of financial resources. Since prices of seed and fertilizer are the major components of cost of production, a rise in input cost may render farm activities unprofitable; this is in line with the disenchantment theory of disadoption (Rogers, 2003). Oladele and Kareem [29] reported that 60% of arable farmers in Oyo state, Nigeria had stopped using fertilizer due to the unavailability, and the untimely and high cost of the input.
Another major factor that farmers mentioned as a constraint to adoption of technology was lack of credit. Partly because of defaulting problems, farmers have found it increasingly difficult to get credit from official sources. Tenkir et al. (2004) indicated that about 40% of farmers who tried new inputs discontinued using them in Ethiopia. (NEGASAl, 1997; Degu, 2000; Feleke, 2006) showed that extension service, access to credit and market, respectively are the main factors influencing the adoption of improved maize seed in Ethiopia. Feleke (2006) also emphasized that access to credit is a powerful policy option in raising the probability of the adoption of improved maize seeds. The households that have adopted improved maize seeds were better off in terms of livestock wealth and average land holding as compared to non-adopters. Kolawole et al. (2003) report on Nigerian farmers who abandoned a technology due to natural hazards and emerging economic constraints. Access to credit, by helping farmers to finance the acquisition of improved seed and fertilizer could enhance adoption and continued use of an agricultural technology.
Montuma et al., found that among those who discontinue the technology have more female family members as improved varieties traditionally required more male agricultural labor tasks and are located farther from the development agents and town markets.
Among the discontinuers more than half of those who discontinue were illiterate, most of them have never hired farm labor, and a third of them were not members of cooperatives.
Neill and Lee (2001) reported farmers in Honduras relayed a legume species after planting maize but the practice was being abandoned at the rate of 10% per year by previous adopters because of the emergence of another weed species that increased labor requirements and reduced maize yields. Oladele, (2005) found that the lack of extension visits and lack of availability of inputs to farmers who have adopted the improved varieties of maize would lead to discontinuance. Igodan, et al [13] reported that farmers who are more exposed to formal extension information have a high propensity towards adoption than those with less exposure. The extension visits will help to reinforce the message and enhance the accuracy of implementation of the technology packages.
Inadequate infrastructure; that is, roads and lack of seed, is another external factor affecting technology adoption and continued use. Households living near major towns have good access to both physical infrastructure and seed supplies, and can purchase seed from the market, hence are expected to continue using adopted technologies. So, the issue of input and market availability should not be allowed to impact negatively on the adoption behaviour of the farmer.

VIII.            CONCLUSION AND RECOMMENDATION:

In developing countries widespread adoption of improved agricultural technologies is one way to eradicate poverty and to ensure food security. However, adoption of new technologies is not sufficient to meet this national need. In addition it must be ensured that farmers use the technology in a sustainable manner. This paper provides insights into the key factors associated with the adoption and continuous use of improved technologies and the results reveal that the age of household influences adoption of technology as younger people were more reluctant to practice new technologies in agriculture. Similarly, educational level was also main factor affecting technology adoption. Households head having formal education had tendency to take risk and could process information more rapidly than others. The farmers having regular contact with extension personnel adopted improved technologies and continued it than people away from extension services. The major factor affecting adoption was distance from market and availability of inputs, there exists inverse relation between market distance and adoption of
The adoption and continued of technology can be achieved by promoting extension visits that would help to reinforce the message and improve the accuracy of implementation technological packages. Similarly timely supply of inputs would lead to decrease discontinuity of adoption of technology. Given the significant role played by extension and access related variables, increased emphasis on information dissemination, field demonstration, and farmers’ participatory research and training programs to popularize new technologies and enhance their adoption rate are required.
