An experiment was conducted at Bihar Agricultural College, Sabour during the year1996-97 to study the effect of different crop regulating treatments on fruit weight and seed weight of guava cv. Sardar. The results revealed that there was more increase in fruit weight and seed weight during winter season as compared to rainy season. However the effect of season on 100-seeds weight was found to be non-significant. There was flower and leaf shedding during rainy season under different treatments resulting in reduced crop yield
