摘要

There is need for an affordable small scale irrigation system in local farmsteads in Nigeria today to help farmers increase their potential for maximum productivity. Consequently, an attempt was made to design and construct a gravitational drip irrigation system for plantain production. The system was used for two cropping seasons of 2006-2007 and 2007-2008. The system includes a main line and sub-mains made up of PVC pressure pipes with diameter 27mm and 19mm respectively. The drippers dissipate water from the laterals through the use of long path tubes (6mm diameter tubing). Water from the overhead tank was supplied to the field by gravity, hence the system requires no energy source for pumping to the field except that required to fill the reservoir from the shallow well. The system was tested for efficiency. The designed water requirement for plantain was computed as 7.85 mm day~(-1). The average discharge value of the emitter was 3.827 h~(-1) which is closer to the designed discharge value of the emitters (4 / h~(-1)). The emission uniformity coefficient of the emitters was 84.2% which is high and considered suitable for the irrigation of the crop under study and acceptable for humid climate (JAMES, 1988). For both seasons, plantain biomass yields were significantly different (p<0.05) in irrigated treatments as compared to the control which was completely rainfed. For instance, biomass yields of T_(100) were 23.2 and 24.41 ha~(-1) as compared to T_0 values of 8.3 and 8.8 t ha~(-1) for 2006-2007 and 2007-2008 seasons respectively. These results suggest irrigation of plantain is necessary to achieve reasonable yield in the region.
