Abstract: A manually operated low pressure low cost (LPLC) drip system was developed from locally available materials using KB pipes，KB pressure treadle pump，pressure drum with microtubes and medical infusion set.The field experiments were conducted and effect of various independent parameters such as vegetative growth，hydraulic performance，crop water requirements，water use efficiency，and cost economics were evaluated on different aspects for tomato and broccoli.The developed system has payback period of one season only with benefit to cost(BC)ratio of 1.59 to 5.31.Thus，appropriate，affordable，divisible，accessible，low operation and maintenance cost，user friendly LPLC drip irrigation system is a good alternative for small land holders.
