Irrigation systems effect on growth and productivity in mango orchard [electronic resource].

Includes references.

The experiment was carried out at the farm of the Egyptian Tank Factory 200, El-Sharkya Governorate, from seedling mango in the first of March 2002 to harvest in August 2006. Mango cultivar Zebda was used to optimize irrigation in mango orchard by evaluating three different irrigation systems on vegetative growth and productivity. Data revealed that the tree height, stem girth and root length density increased more under using the sub-surface irrigation (SSI) than drip irrigation (DI) and furrow irrigation (FI). The average crop coefficients for the mango orchard productive cycle were ( Kc = 0.69, 0.74 and 0.85)under SSI, DI and FI, respectively . The furrow irrigation causes the shot holes split disease, more than drip irrigation and sub-surface irrigation. It was 2.7, 2.1 and 0.6 % under using FI, DI and SSI, respectively. The average yield of mango under using SSI increased by 13.88% and 26.25% from DI and FI, respectively, because of the weed management, moisture distribution in root zone and irrigation efficiency with SSI best among other irrigation methods.
