Abstract
This study pursued to investigate sustainable methods to increase growth and yield of sweet pepper. To realize this purpose, a plastic house experiment was done, and two factors were studied under split-plot design. The main factor was focused on the application of mineral and organic rates (100% NPK,75% NPK+ 25% chicken manure, 50% NPK+ 50% chicken manure). The sub main factor was spraying of the organic liquid tea, specifically compost tea and vermicompost tea, in addition the Control treatment to study its effect on vegetative growth, chemical constituents, photosynthetic pigments, yield and quality. The results cleared that the treatment of 100% NPK of recommended dose enhanced vegetative growth, while 75% NPK of recommended dose + 25% chicken manure enhanced chemical contents in leaves and fruits in addition enhanced yield and quality. Concerning the impact of the organic liquid tea, the maximum values of all studied traits obtained from spraying vermicompost tea compared to other applications. It is evident that the combination of 75% NPK of recommended dose + 25% chicken manure and spraying with vermicompost tea showed a bilateral interaction that was noticeably better than other interactions. Growers may improve the productivity and nutritional value of sweet peppers by taking these suggestions into practice, which will ultimately benefit both producers and consumers.
