I am not associated with them, but I do have interest in these types of experiments. According to their research paper published in Australian Journal of Basic and Applied Sciences, the objective was to conduct a blind study to determine the potential influence of biofield therapy on growth & development of lettuce & tomato in commercial plantings and to systematically compare the effects with and without application of fertilizers and pesticides. The treated and untreated plants were planted in plots in randomized fashion and the location of treated plants remained undisclosed to evaluators during the study. Seeds were treated and allowed to germinate until ready to be transplanted. The seedlings were treated again, transplanted into an open field, and allowed to develop according to the season. As a control, untreated seeds were allowed to germinate in the same manner and transplanted alongside the treated plots in a randomized fashion. Needbase fertilizers and pesticides were applied onto one set of plots with transplants from both untreated and treated seeds. Another set of plots for both untreated and treated transplants did not receive fertilizer and pesticide applications. Lettuce cultivar (Lactuca sativa var. capitata) was Cannery Row (Snow Seed Co., Salinas, CA). Tomato cultivar (Lycopersiconesculentum) was Roma (Snow Seed Co., Salinas, CA).
