Economics of Drip Irrigated Closely Spaced Crops

WithKamal G. Singh, H. A. W. S. Gunathilake, Ramesh. P. Rudra, and Pradeep K. Goel

Cost of a drip irrigation system is comprised of: the capital investment; cost due to water pump, head control components, main line, laterals, emitters; installation cost; the operating cost of pumping energy, pump maintenance, lateral maintenance; and system operating labor cost, etc. Comparatively, the capital cost is predominant in any drip irrigation system. Therefore, in designing the system, the priority is given to plot an optimal geometrical layout of the system (lateral spacing and emitter spacing) without affecting the number of plants (plant density).
