ABSTRACT
In the present study, an attempt was made for the comparative evaluation of porous pipe subsurface irrigation with inline and online drip irrigation in sandy loam soil. The study revealed that, at all operating pressures, viz., 0.4, 0.8 and 1 and 1.2 kg/cm2; the discharge rate of the porous pipes installed at different depths (7.5, 15, 22.5 and 30cm depths), was found to decrease with increase of time. The optimum operating pressure for the porous pipe in sandy loam soil having 1.6 cm inner diameter was found to be 0.8 kg/cm2 and porous pipes were having only medium distribution efficiency. The porous pipe installed at 22.5 cm depth was found to exhibit maximum soil moisture distribution efficiency and discharge rate. The performance evaluation of porous pipe in bhindi crop field revealed that porous pipe cannot be recommended for irrigating the plants since it get clogged even after one year and also in the first year itself it gave only medium distribution efficiency.
