FURROW
There are several disadvantages with furrow irrigation. These may include: (1) an accumulation of salinity between furrows; (2) an increased level of tail water losses; (3) the difficulty of moving farm equipment across the furrows; (4) the added expense and time to make extra tillage practice (furrow construction); (5) an increase in the erosive potential of the flow; (6) a higher commitment of labor to operate efficiently; and (7) generally furrow systems are more difficult to automate, particularly with regard to regulating an equal discharge in each furrow (F.A.O 2013).

Examples of irrigation system are,Perennial irrigation (Dams)Direct irrigation (river canal irrigation)Storage irrigation (tanks and resevoirs)
`Chain pump system of irrigation is a traditional method of irrigation.
need of irrigation: insufficient of rainfall uneven distribution of rainfall improvement of perennial crops. mode of irrigation: 1. Lift irrigation 2. flow irrigation
Furrow irrigation should be used on slopes. Furrow irrigation creates parallel channels along the length of the slope.

It sprays water over the top of the plants, similar to a gentle shower. Not as efficient as drip irrigation, but much more efficient than flood or furrow irrigation.
The definition for furrow is " A long narrow trench made in the ground by a plow, esp. for planting seeds or for irrigation." Some of the synonyms for the word furrow are line, wrinkle, crease, groove, rut, and wake.

Only about 20% to 40%, depending on how it's done. Furrow irrigation can boost this to about 50% to 60%. Drip irrigation is still the most efficient, occasionally reaching nearly 90% efficient.
Bullocarts are used to plough the field in traditional periods. Irrigation is also done manually by collecting water from wells and pouring in the linings. the traditional methods of irrigation are .furrow .chainpump .moat .dhekli .rahat
