Development of Low Pressure Fertigation Injector
There has been a tremendous growth in fertilizer use throughout the world in the twentieth century. By the end of twentieth century, developing countries had increased the utilization of fertilizers to 60% of the world’s fertilizer use and produced 55% of total nitrogenous fertilizer . Drip irrigation offers several advantages like high irrigation efficiency, labor and energy savings, improvement in quality and yield of produce and opportunity to manipulate inputs, as per the crop demands, over the conventional irrigation method. Black , Miller et al. , Kaneworthy  and Smith et al.  indicated that there was a saving of up to 50% of the fertilizer, when applied through a drip irrigation system.
