The existing pumping system adopted in the region dependsupon the supply of either electricity or fossil fuels. Additionally, theexisting lifting pumps for drawing water from bore-well have high suction:delivery head ratio, are uneconomical for small-scale applications.
Affordability of these systems to the smallholding farmers is a major concern as the operational cost overshadowed the profitability.
Thus to avoid these economic liabilities associated with existing pumping system and increase the profitability from limited
land and climate resources, this class of farmers usually goes for hand watering. Thus, in these conditions, the most befitting pumping system should have low suction:delivery ratio.
pumping system should have low suction:delivery ratio.
Micro-irrigation technologies are widely considered as one of
the most effective and efficient method of irrigation (Keller and
Bliesner, 1990). Several studies in the past have been carried out
