| Abstract | ||||
| Two field experiments were conducted to assess the growth and productivity of hot pepper (Capsicum annuum L.) at Assiut Agr. College Farm, Assiut Uni., Assiut Governorate. Egypt. Experiments were conducted during the cropping season of 2018/2019 and 2019/2020 under development irrigation system. The study consisted of 2 released hot pepper varieties (Ealaganle and Bigmama3), 2 foliar concentrations of salicylic acid and potassium silicate (PS) were tested. Treatments were laid out under Split plot design with three replications where, variety was assigned as main plot factor, foliar concentrations were arranged as sub plot factors, respectively. Data were collected for physical quality of Hot Pepper fruit (Capsicum annuum L.) and fruit Productivity. Analysis of variances (ANOVA) revealed that varieties differed significantly (P≤0.05) in Fruit physical quality of Hot Pepper fruit (Capsicum annuum L.) and fruit Productivity. Ealaganle var., surpassed Bigmama3 var., in Fruit physical quality of Hot Pepper fruit (Capsicum annuum L.) and fruit Productivity. Results proved that spraying Ealaganle var., with 8 ml/L of PS 9 times significantly increased pepper fruit yield and yield attribute. Application of potassium silicate at 4 and 8 ml/L gave the maximum Hot pepper yield (21.14 & 20.03%) for T4 and (32.17 & 30.97%) for T5 compared to the control (T1) in the 1st and 2nd seasons, respectively. Additionally, a positive and highly significant relationship between yield and harvest frequency was recorded. | ||||
