The decision support system (DSS), namely Design of Micro Irrigation Systems (DOMIS) has been developed to design drip, sprinkler and micro-sprinkler irrigation systems. This provides expert opinion for optimal layout plans for MI system design by using the necessary data on crops, soil characteristics, groundwater and agri-climatic conditions as default options with a provision to modify as preferred by the user. The design includes selection of pipe sizes, pumping system, filters and fertilizer application systems along with possible shifts per day in case of sprinkler irrigation system and total time of irrigation. The web-based system (http://domis.iari.res.in) uses scientific algorithms and expert suggestions; the flexibility of DSS and ease of use make the DSSDOMIS a superior tool for designing micro-irrigation systems with a view to enhance water productivity in agriculture. It also provides general information about different Government schemes, central and state agencies promoting micro irrigation, approved system suppliers in different states and general information about different districts in the country. The DSS helps farmers as well as policy makers and researchers obtain optimal design and cost estimates of a micro-irrigation system.Keywords

This study reports the effect of surface and subsurface drip irrigation with municipal wastewater and groundwater on growth and yield of cauliflower. Eight treatments were evaluated: surface drip (T1), subsurface drip (non-pressure compensating) (T2), bioline subsurface drip (T3) and bioline (pressure-compensating) surface drip (T4) using groundwater, and the same drip systems using primarily treated municipal wastewater (i.e. T5–T8). Results showed maximum leaf area index and ischolar_main length density (5.64 and 5.25 cm/cm3 respectively) of cauliflower in subsurface drip system having pressure-compensating lateral applying wastewater and minimum (4.48 and 4.05 cm/ cm3 respectively) in surface drip system having inline lateral applying groundwater. The highest curd yield (79.67 tonne/ha) was found with subsurface pressurecompensating drip with wastewater application, whereas lowest (59.01 tonne/ha) was recorded in case of inline surface drip with groundwater. The cauliflower curd yield increased by 7.58% and 8.49% under surface and subsurface pressure-compensating drip laterals with wastewater application, with a saving of 30.1% nitrogen, 14.14% phosphorus and 33.7% potassium, compared to groundwater-irrigated treatments.Keywords
