In addition, there are more than a few who are anxious about the expansion of the gap between the large-scale wealthy farmers and the poor farmers or landless workers because of the changes to the social customs in rural areas brought by the introduction of modern varieties, where they had previously employed many landless workers at harvest time for the traditional varieties (7), and for instance, by changing the harvesting tools from 'aniani' to sickles in Indonesia after the advent of the Green Revolution. (8)
Then, it used to be said that it was difficult for small scale farmers, who have long been growing the traditional varieties which did not require fertilizers, to adopt modem agricultural methods which require water supply and fertilizers for production of modem rice varieties. However, as Shultz said, even though small scale farmers are not particularly knowledgeable, once they find that one agricultural product brings a certain profit, they have the ability to grab these economic opportunities. If they see their neighbor's farmers getting a guaranteed profit through introduction of the Green Revolution, they will surely try to adopt the new technology. (9)
Farmers respond sensibly to changes in the price ratio between fertilizers and rice in both of the developed and developing countries, and take rational economic action. Table 3 shows the recurring result between the relative price of fertilizer against rice and fertilization costs per hectare, although the determination coefficient is not so high, fertilizer's t-value parameters of relative price to rice is meaningful, and it proved this rationale.(10)
There is an assertion denying the opinion that it causes increase inequality of income distribution in rural areas. Kikuchi established by the analysis of the rural areas in Laguna, Philippines, that the Green Revolution raises the income for laborers relative to the cost of the land, and it reduces economic inequality.(11)
Hayami also confirmed that small scale farmers introduced the modem varieties at an earlier stage through research in 30 rural areas in Asia (12), while Cristina David and Otsuka reached a similar conclusion from their research within seven Asian countries in 1985-1988 as well. (13) It may be natural to think that small scale farmers introduced the modem varieties earlier, except in the initial period
