Onion Response to Drip Irrigation Intensity and Emitter Flow Rate

Emitter and filter tests for wastewater reuse by drip irrigation

Agriculture is the main user of water in Italy, as in most regions of the world. Particularly in Mediterranean regions, where it is more difficult to meet the agricultural water demand with conventional resources, wastewater reuse represents a viable option. Drip irrigation is particularly suitable for wastewater reuse because it minimises the health risks to farmers and product consumers due t...

Effect of deficit irrigation on crop growth, yield and quality of onion in subsurface drip irrigation

Indiahas the largest area under onion (Allium cepa) crop but its average productivity (14.21 t ha-1) is considerably lower than the world’s average of 19.4 t ha-1. Besides low productivity, irrigation efficiencies are also very low i.e. 30-35% in India. Managing onion crop with less than adequate irrigation water availability is a challenge in several parts of the country. Options of i) deficit...

Simulation of the flow characteristics of a drip irrigation emitter with large eddy methods

Realizing the internal flow visualization inside the drip irrigation emitter is the basis of optimizing the labyrinth path structure and promoting its anti-clogging capability. The Computational FluidDynamics (CFD)method has become an effective approach to research the water movement in the labyrinth path of the drip irrigation emitter. In this paper, the standard k-ε model and the Large Eddy S...

Modeling the future of irrigation: A parametric description of pressure compensating drip irrigation emitter performance

Drip irrigation is a means of distributing the exact amount of water a plant needs by dripping water directly onto the root zone. It can produce up to 90% more crops than rain-fed irrigation, and reduce water consumption by 70% compared to conventional flood irrigation. Drip irrigation may enable millions of poor farmers to rise out of poverty by growing more and higher value crops, while not c...
