cultivators that are readily available commercially and mechanical land preparation, after

data collection in order to further increase the reliability of the instrument. Nine items

remained in the index for analysis (Appendix C, Table 2).

 I created one and two dimensional indices to measure subjective norms, normative

beliefs, self-identity, self-efficacy, control beliefs and resource access. I used an expert

panel to create these indices. The Delphi method is a technique used to identify items

about which there is consensus among a group of experts (Adler & Ziglio, 1996). This

approach aims to get experts' opinions about a subject by using a series of questions with

controlled opinion feedback (Adler & Ziglio, 1996). I first compiled a list of nine experts

in agriculture. These experts included farmers, agricultural extension agents and

agricultural service providers. I created a list of topics and questions that related to each

variable measured. I then asked the expert panel to list 7-10 items that would answer the

questions for each variable. Next, I created a rule to determine which items to keep on

the list. I kept the items that 40% of respondents said were important. I then created a list

which included these top responses and sent them back to the panel and had each person

rank the items for importance on a 1-5 scale. I then took the mode for each item and kept

the most consistent four to six answers. These items were included in the final indices

that measured the variables (Appendix C, Tables 3 through 12).

 I developed two indices to measure self-identity, control beliefs and access to

resources. I created a modem identity index and traditional identity index to measure

self-identity. I created a modem control belief index and traditional control belief index

to measure control beliefs. Lastly, I created a modern resource access index and

traditional resource access index to measure access to resources. I developed two indices

for each of these variables to determine if the modern and traditional indices are
