Bell pepper (Capsicum annuum) has been in high demand since ever. High quality of fruit and increased yield are desired characters both for the researchers and the growers. The impact of foliar application of chitosan (CHT), Salicylic Acid (SA) and Putrescine (PUT) on fruit yield and physico-chemical characteristics of "Yolo Wonder" bell pepper cultivar was studied for two consecutive years (2012 and 2013). Results indicate application of chitosan (0.5), putrescine (3 mM) and SA (3 mM) increased fruit weight, fruit diameter, and yield as compared to control and other treatments. Fruit firmness was increased in PUT (2 mM, 3 mM) and SA (3 mM) as compared to control. Furthermore, fruit harvested from these treated plants did not affect days to fruit maturity and number of fruits per plant. Higher PUT (3 mM) and SA (3 mM) concentration proved significantly better in reducing disease incidence. Present research proves SA and PUT sprays more effective than CHT for improving fruit physical and chemical characteristics such as fruit size, fruit weight, yield, fruit firmness, and vitamin C content. Finally, the biostimulants used in this study can easily be used to improve yield and quality of bell pepper without compromising the food safety standards. [ABSTRACT FROM AUTHOR]
