Abstract
Surge flow furrow irrigation is a new irrigation technique for controlling furrow irrigation. The main purpose of this study was to investigate the effect of surge furrow irrigation comparing with continuous irrigation on water management and yield of maize with different ploughing methods. Field experiments were carried out at Zarzora Agricultural Research Station, Etay El-Baroud, Beheira Governorate, Egypt during 199811 999 growing season. It was divided into three main plots; each plot was 17 m wide and 95 m long. The main plot was assigned to plowing systems. Each plot was divided into four strips (sub-main plots). The area of each strip was 332.5111’. The sub-main plot was assigned to irrigation treatments. The soil type is clay loam soil. The furrow has 95 m length, and 0.70 111 width, 0.04% slope, and 0.037 Manning’s roughness (n). The treatments were studied and tested in this work as follows: - Ploughing treatments (main plot): 1 - Moldboard plough (ploughing optimum depth 25 cm). 2- Chisel plough (ploughing optimum depth 20 cm). 3- Rotary plough (ploughing optimum depth 12 cm).
