The purpose of this pilot study was to describe the participation of farm women in farm work in one California country. Women from 228 farms, approximately 55 percent of the farms in Yolo County, California, were interviewed by telephone concerning their efforts and roles on the family farm. The study found that the main criterion of whether or not the women actively participate on the farm appears not to be farm size as much as the need for the extra work women supply as part of the family unit. Thus, the woman is less likely to be involved in the operation when labor can be sufficiently tapped through the husband, the male children, the extended family, or hired help. On the other hand, if such sources of labor are unavailable or if the husband has an off-farm job, then the woman can be expected to have a greater degree of involvement in each of the three dimensions of farming: decision making, production tasks, and management support services. The study also found that women who are more involved tend to be better educated, younger, and more cognizant of problems encountered by farm women. They are also more likely to live on the farm and to perceive technology as having increased female activity in farming. The study concluded that women participate in farming much more than is generally recognized. Given current trends, their involvement in both decision making and task participation will continue to grow. Besides these two crucial areas, women contribute to farming by working outside jobs to help support marginal farm operations.
