Amino acids foliar spraying palliate the negative effects of low irrigation on greenhouse sweet Cayenne pepper

Sweet Cayenne pepper is a nutrient-dense, sweet-tasting greenhouse vegetable that often faces water stress in dry areas, and optimizing growth with minimum consumption crucial. In this study, we investigated the impacts of amino acids (AAs) foliar application on reducing losses sweet cv. “Lombard” under conditions. The bushes were irrigated 3-day 6-day intervals simultaneously sprayed an AA fertilizer (0, 150, 300 mg/L). Vegetative growth, reproductive traits, yield parameters measured. Results showed significant decreases plant height, roots length, SPAD, leaf greenness index, leaves turn yellow brief drought stress. number flowers was reduced by up to 50%, 3-month decreased significantly from 7 5.05 kg/m2. However, AAs application, vegetative fruit number, increased significantly. highest yield, 2.93 kg/plant, observed mg/L AAs, while average 1.83 kg/plant recorded treatment without application. spray remarkably improves quality reverses destructive effects low irrigation. future direction could focus mechanism positive impact fruit, particularly conditions, further optimize minimize consumption.
