“…Onion Y obtained in the EAU4Food project were comparable to those obtained in other irrigation experiments in Ethiopia (Bekele and Tilahun, ; Kifle et al, ) (Table III). Bekele and Tilahun () subjected onions to different levels of deficit irrigation (gravity drip) at different phenological stages in Wollehat Sekota (north‐eastern Ethiopia).…”

Agriculture in developing countries will have to transform and increase production by an estimated 70% in order to meet demands by 2050. Although well‐managed commercial farms offer little manoeuvring space for increasing agricultural water productivity, smallholder farms usually operate at low input costs and therefore provide ample opportunities to reduce the potential yield gap through agricultural intensification. The aim of this paper is to analyse and compare yields and water productivities obtained in field and modelling experiments in Ethiopia (maize, garlic, onion), South Africa (tomato) and Tunisia (tomato, potato, wheat). Innovative agricultural practices were introduced on smallholder farms: irrigation scheduling and NPS Zn fertilization in Ethiopia; high‐yielding cultivar, drip irrigation, mulching and organic amendments in South Africa; and crop water modelling in Tunisia. In general, crop yields increased up to eight times with innovative practices compared to current conventional farming practices. Crop water productivities were fairly stable within the same experiments, but increased with innovations, indicating that intensive farming can be more environmentally sustainable than conventional farming. Intensive farming systems in a resource‐rich environment (high radiation levels, relatively fertile, deep and well‐drained soils), combined with technology transfer and capacity building could be seen as viable strategies to secure food for smallholders and communities in African rural areas, as well as to improve water utilization in water‐scarce catchments.

“…From these calculations, the E a values for surge flow treatments were higher than those for continuous ones. This can be attributed to the rapid advance of the waterfront for surge flow treatments (Ismail et al, 1985(Ismail et al, , 2004Kanber, 2001;Kifle et al, 2008). On the other hand, the E a value for the 4-surges treatment with the mouldboard plough was the highest.…”

“…This may be due to a higher off-time between surges that reduced infiltration rate, according to Samani et al (1985). Generally, the surge flow treatments had a faster advance rate than the continuous ones (Horst et al, 2007;Ismail, 2003;Kanber, 2001;Kifle et al, 2008;Latif and Ittefaq, 1998). This may be attributed to the redistribution of the infiltrated water in the soil profile during the off-time, particle sealing of the wetted soil surface, and the creation of a smooth surface for the next surge (Izadi et al, 1990;Segeren and Trout, 1991;Trout, 1991).…”

“…Horst et al (2007) observed that the best irrigation water productivity was achieved with surge flow on alternate furrows, which reduced irrigation water use by 44% and led to high application efficiency (85%). Kifle et al (2008) reported that surge flow treatment with lower discharge rates and a lower cycle ratio performed better in reaching the tail end of the furrow, with an advance time 23% faster than a comparable continuous flow.…”

“…Many authors and investigators (Eid, 1998;El-Zaher et al, 1996;Horst et al, 2007;Kifle et al, 2008;Wang et al, 2005) have summarised the potential benefits of using surge rather than continuous irrigation. Bishop et al (1981) reported that in a surge furrow irrigation experiment with cycle times of 2, 5, 10, and 20 min and with a cycle ratio of 0.5 and a discharge rate of 1.26 l s -1 , surge flow irrigation was more effective during the first irrigation than in the second one.…”

A b s t r a c t. Surge flow irrigation is one of the irrigation techniques for controlling furrow irrigation. The aim of this study was to investigate the effect of surge furrow irrigation on water management compared with continuous irrigation for different tillage systems. An experimental field was treated with various tillage systems (mouldboard plough, chisel plough and rotary plough) and water irrigation application methods (continuous flow, control) in which irrigation water was applied continuously, and surge flow (3-surges, 4-surges and 5-surges) in which irrigation water was applied intermittently until it reached the tail end of the furrow. The results showed that water savings obtained using the surge technique were 18.58, 11.84 and 18.93% lower water use than with continuous flow, for the mouldboard, chisel and rotary ploughs, respectively. The 3-surges treatment with the rotary plough reduced the advance time by 25.36% from that for continuous irrigation. The 4-surges treatment with the mouldboard plough had the highest water application efficiency (88.13%). The 3-surges treatment with the rotary plough had the highest distribution uniformity (85.01%). The rotary plough did not cause as much soil aeration around the root system as the other tillage systems. The field research provided information about surge flow, aimed at reducing advance times and increasing irrigation efficiency.K e y w o r d s: irrigation, ploughing system, water application efficiency, distribution uniformity, advance rate INTRODUCTION
