| Abstract | ||||
| Growth, yield, and quality for two hybrids of color sweet pepper as influenced by some stimulant materials i-e chitosan with concentration (250 ppm), melatonin with (50 ppm) and potassium silicate with (2000 ppm) in addition to control. were studied. The experiments were carried out in two successive seasons 2021/ 2022 and 2022/ 2023 at the farm and laboratories of the Horticulture Department Faculty of Agriculture Minia University, El Minia Governorate, Egypt, under plastic house conditions. The experiment was laid out as CRBD in the split plots design where the two hybrids were done out in the main plot and the stimulant materials were distributed in a subplot with three replicates. The results revealed that most growth parameters, yield, and its components such as average fruit weight and the number of fruits/plant in addition to some fruit quality i-e fruit wall thickness were improved significantly after spraying these materials compared to control plants (those plants which sprayed with water). Among these materials spraying plants with potassium silicate improved the number of fruits/plant, number of branches/plant, fresh weight of plant, and total yield. While spraying with melatonin had improved the average fruit weight, average fruit length, and dry weight of the plant, on the other hand spraying with chitosan had improved the average plant height. | ||||
