<p>This study aimed to predict the likelihood of government high school principals and science teachers in Rawalpindi, Pakistan, adopting school vegetable gardens using the Theory of Planned Behavior framework. Specifically, the study examined: (1) how theory’s components (attitudes, subjective norms, perceived behavioral control) predict intentions to use school gardens, and (2) the effects of demographic factors like gardening experience and qualifications on these theoretical constructs. A survey of 122 principals and teachers from 22 government high schools revealed that all three components of the Theory of Planned Behavior significantly predicted intentions to use school vegetable gardens. Importantly, participants who engaged in personal gardening or farming demonstrated substantially higher scores on intentions, perceived control, and both cognitive and affective attitudes compared to those without such experience. Educational qualifications related to agriculture also positively influenced attitudes and perceived control, even in the absence of practical experience. The key findings indicated that all three components of the theory of planned behavior; affective and cognitive attitudes, subjective norms, and perceived behavioral control significantly predicted intentions to use school vegetable gardens; demographic variables of gardening or farming in personal time rendered a significant and positive effect on all the components of theory of planned behavior; significant differences were observed between two groups of those who gardened or farmed in their time and those who did not about components of theory of planned behavior.</p>
