Abstract

Suitable irrigation method with application level is essential for adaptation and adoption in the areas where water resources are limited. Therefore, a field experiment was conducted to test the performance of alternate furrow irrigation (AFI or FFI) and convectional furrow irrigation (CFI) with three water application level on crop, yield response, water use efficiency and cost benefit analysis of cabbage. The experiment had two factors, factorial design arranged in Randomized Complete Block Design (RCBD) with nine treatments of three replicate. The treatment namely three furrow Irrigation method alternative Furrow Irrigation (AFI), Fixed Furrow Irrigation (FFI) and Convectional Furrow Irrigation methods (CFI) and three application levels full (100%), three forth 75% and half 50% of full ETc (crop water requirement). The result shows CWUE, IWUE and EWP were highly significantly (P<0.01) affected by both IMs and ALs. The highest and the lowest mean crop and irrigation water use efficiency (CWUE and IWUE), and economic water productivity (EWP) were recorded by AFI and CFI irrigation. Whereas, under ALs the highest and the lowest mean CWUE, IWUE and EWP were recorded by 50% and 100% ETc Application depth. Maximum water saved resulted from AFI and FFI, with 50%, 75% and 100% ETc application depth was equally computed as 58.33%, 37.50% and 16.67% which could irrigate additional area of 0.20, 0.60 and 1.40 ha for each treatment respectively. Contrarily yield reduction was higher in FFI followed by AFI and CFI with the same ALs. NR (net return) produced per hectare was higher in CFI followed by AFI and FFI. In case of BCR, AFI with 75% and 50% ETc was higher than FFI followed and the smallest by CFI of 50% and 75% ETc deficit level. Hence yield reduction and NR incurred by alternate (AFI and FFI) were compensated from additional irrigable area by diverting the water and labour saved. Generally from over all investigation of CWUE, IWUE, EWP, NR and BCR alternative furrow irrigation method (AFI) was better than FFI and CFI for the water scarce area.
