Trickle Irrigation: Prevention of Clogging
Transactions of the ASAE, 1979ABSTRACT TRICKLE irrigation experiments using Colorado River irrigation water on citrus trees in south-western Arizona were conducted to evaluate clogging of emitters and to investigate methods for controlling clogging. Clogging is related to the water quality in terms of the suspended sediment load, chemical compo-sition, and biological activity ...

Trickle Irrigation Uniformity and Efficiency
Journal of the Irrigation and Drainage Division, 1978Expressions are developed and presented for the pressure head available at any point within a trickle irrigation subunit. Histograms are drawn showing the distributions of pressure within typical subunits. Distributions of emitter flow rates within typical subunits are derived from considerations of the effects of pressure differentials and ...

We previously developed a new, coupled‐source–sink modeling approach for evaluating an upper bound to the relative water uptake rate (water use efficiency) for two‐ and three‐dimensional geometries. Because the formulated water‐flow problem is linear, the relative water uptake rate for any given collection of point (or line) sources and point (or line)

Trickle irrigation water quality and preventive maintenance
Agricultural Water Management, 1979The most serious problem in trickle irrigation is clogging of emitters or applicators. Recommendations and guidelines are presented for preventive maintenance which include water filtration, chemical treatment, pipeline flushing and field inspection. A suitable type, size and capacity of a filtration unit is required.

Trickle irrigation of sunflower with municipal wastewater
Agricultural Water Management, 1991Abstract A field experiment was carried out for three years on a Calcaric Lithosol to study the influence of treated municipal wastewater in comparison with freshwater, supplemented with four N or P levels, on soil fertility and on growth and yield of trickle-irrigated sunflower ( Helianthus annuus L.).

Yield response of bananas to trickle irrigation
Australian Journal of Experimental Agriculture, 1981Supplementary trickle irrigation applied twice a week by single microtube at replacement rates of 0 (control), 20, 40, 60, 80, 100 and 120% of Class A pan evaporation (El from 1970 to 1976 increased bunch weight significantly (P= 0.02) above 40% E. Treatment 60% E gave a bunch weight of 27.6 kg compared with 25.7 for the control. The control, 20 and 40%

Designing Trickle Irrigation Laterals for Uniformity
Journal of the Irrigation and Drainage Division, 1974Design equations are derived that can be utilized to calculate the maximum lateral length for a given value of the uniformity coefficient. The solution depends upon the emitter flow function, elevation change, pipe size, reduction coefficient for dividing flow, pipe roughness coefficient, the average emitter flow rate, and either the average emitter ...
