Correlation between Water Deficiency, Yield Components and Crop Productivity of Banana

Water is a limited factor that significantly influence productivity of banana and is needed to ensure optimum yield. Currently, Grand Nain is becoming a popular banana cultivar in Sudan, but the yields are low due to improper water management and agricultural practices. To investigate the effect of irrigation water quantity on the growth and yield of banana crop, a field experimental was conducted during the period of 2009-2010 on the eastern bank of the Nile River, 54 km of North Khartoum, Sudan. In the concerned experiment a randomized complete block design was used, where three different irrigation water quantities of 1.0 ETc, 0.75 ETc and 0.5 ETc at an irrigation interval of two days using gated pipe (hydroflume). The results showed that the growth parameters, hydraulic performance, water use efficiency and the productivity were significantly response to the water quantities, where all parameters increased with increase of water amount. The highest values of above mentioned parameters were obtained by 1.0 ETc followed by 0.75 ETc and 0.5 ETc respectively. Using hydroflume improved irrigation efficacies, also the production indicators showed that the banana crop agronomic parameters response negatively with water deficiency. To improve productivity of banana in Sudan, and other semi ecological areas, more attention should be given to research geared towards improved water and unlike environmental conditions stress management.
