Performance Evaluation Of Furrow Lengths And Field Application Techniques

Abstract: The study evaluated performance of furrow lengths and field application techniques. The experiment was conducted on 2000 m2 field at Bontanga irrigation scheme. Randomized Complete Block Design (RCBD) was used with three replicates. The replicates include Blocks A, B and C of furrow lengths 100 m, 75 m and 50 m respectively. Each replicate had surge, cut-off, cut-back and bunds treatments. Water was introduced into the furrows and the advance distances and time were measured. Results of the study showed that at Block A, surge technique recorded the highest advance rate of 1.26 min/m and opportunity time of 11 min whilst bunds recorded the lowest advance rate of 0.92 min/m. Significant difference (3.32, p≥0.05) occurred between treatment means of field application techniques at Block A (100 m). Significant difference (2.71, p≥0.05) was also recorded between treatment means. At Block B (75 m) there was significant difference (2.71, p≥0.05) between treatment means. No significant difference (0.14, p≤0.05) was observed among surge, cut-back and bunds techniques. There was significant difference (2.60, p≥0.05) between treatment means, but no significant difference between cut-back and bunds techniques in Block C (50 m). Their performance was ranked in the order Surge > Cut-back > Cut-off > Bunds for furrow lengths 100 m, 75 m and 50 m respectively.
