NONE
Step-by-step solution
1. Furrow irrigation involves constructing small parallel channels or ditches along the field length. 2. Crops are planted on the raised ridges between these ditches, while water flows through the furrows to soak into the soil. 3. This method minimizes direct contact of water with crop stems and reduces evaporation losses compared to flood irrigation. Answer: B
Explanation
Furrow irrigation is a surface irrigation method where small parallel channels or trenches called furrows are dug across a field. Water flows down these channels, and crops are planted on the ridges between the furrows so their roots absorb water laterally. This system helps conserve water and prevents direct crop inundation compared to flood irrigation.
Why the other options are wrong
A) Flood irrigation involves covering the entire field with water without ridges or furrows. C) Check irrigation involves dividing the field into level plots surrounded by levees. D) Option B is the correct answer.
Shortcut
Ridges and water ditches = Furrow Irrigation.
Common mistake
Confusing furrow irrigation with check or flood irrigation, where water covers the entire land surface rather than moving along channels.
Correct answer: B) Furrow Irrigation
