Description
Summary:The experiment was conducted in Horticultural Facilities Unit of the Department of Horticulture and Landscape - College of Agriculture - Tikrit University. Iraq for the period from 3/15/2020 to 1/15/2021. The experiment was designed as a randomized complete block design (RCBD). The experiment included two factors: first shading with two levels without shading (open field) and lath house (net 33%). second spraying with chitosan in three concentrations 0, 500, 1000 mg. L −1 . Results showed that shading treatments exceeded in length and width leaves gave 52.08 cm and 17.8 mm. open field gave highest Diameter of the basal florets 34.32 mm, foliar with chitosan 1000 mg.l −1 gave highest leaves number 19.12 . Length and diameter of syphilitic Peduncle recorder in interaction between lath house and foliar chitosan 1000 mg.L −1 was 109.02 cm and 9.21mm respectively.
