ﺛﻴﺮ ﺗﺮاﻛﻢ ﻛﺸﺖ و ورﻣﻲ ﻛﻤﭙﻮﺳﺖ ﺑﺮ رﺷﺪ و ﻋﻤﻠﻜﺮد ﮔﻴﺎه ﻋﺮوﺳﻚ ﭘﺸﺖ ﭘﺮده (Physalis peruviana L)

Gooseberry (Physalis peruviana L.) belongs to Solanaceae is well known for its nutritional and medicinal values and is native to South -America. In order to investigate the effect of planting density (50, 75 and 100 cm inter-row distance) and vermicompost (0, 5, 10 and 15 t.ha-1) on growth and yield of gooseberry, an experiment was conducted as factorial based on complete randomized block design with three replications in Research Station of Department of Horticultural Sciences and Landscape, University of Tehran, in 2013. Criteria such as collar diameter, number of lateral branches per plant, plant height, fruit yield, fruit marketable percentage and plant dry weight were evaluated. Results showed that treatments significantly affected all measured criteria in which application of 15 t.ha-1 vermicompost increased all measured criteria compared to control (non-vermicompost application) about 18.97, 16.69, 13.07, 35.47 and 11.48%, respectively. Also, inter-row distance of 100 cm performed better than 50 cm in case of all measured criteria. Interaction effect of planting density and vermicompost had not significant effect on all studied criteria.
