Abstract
Recently, there has been increasing concern about reducing and replacing chemical fertilizers with biofertilizers to enhance soil fertility and maintain agroecosystems and sustainable agricultural production. Given that knowledge of biofertilizers is information-intensive, the lack of information-seeking behavior (ISB) might be the primary constraint for farmers adopting biofertilizers. This study aimed to analyze how ISB influences farmers' adoption of biofertilizers, using a sample of 228 onion farmers in Al-Ahsa Governorate, Saudi Arabia. The results indicate that most farmers had a moderate level of ISB. The most frequently accessed sources were mobile applications, extension institutions, and progressive farmers. The results of cluster analysis show that farmers' ISB differed significantly according to their main occupation. Among the onion farmers, 35%had adopted biofertilizers. The findings also reveal that farm size, attitude toward biofertilizers, the credibility of information sources, and the usefulness of the information positively and significantly influence farmers' adoption of biofertilizers. It was concluded that understanding the relationship between adoption and ISB could assist policymakers in focusing on knowledge diffusion when designing extension programs and advisory services to facilitate better usage of biofertilizers.
