How to make Open Access to reach agriculture researchers in India

Its my view that Open Access concept had not reached researchers in agriculture especially in India. From the time when first OA workshop was conducted by MSSRF in 2004 till date, we have only few journals are OA and very few OA repositories. When I suggest/ask my colleagues to make their articles open, they first say, no its all copyright protected, I shall not do that. When I approach the administrators/managers, they say OA is not much important you first publish in high impact factor journals. We have now rating of journals in India by NAAS. They have given some rating and all the research staff is happy to publish in high rated journals and forget about whats the article's impact is about. Mean, does anyone citing? or does anyone is trying to improve upon that article?
