INTRODUCTION TO MICRO-IRRIGATION SYSTEM presentation on :- Subject: - Micro irrigation system designPresented by: -JOSHI DRASHTI ( PAGEN-096-2012 )KAUSHAL .V. GADARIYA (PAGEN-097-2012) WHAT IS MICROIRRIGATION SYSTEM?-Micro-irrigation refers to low-pressure irrigation systems that spray, mist, sprinkle or drip.-The term micro irrigation describes a family ofirrigation systems that apply water through smalldevices.-These devices deliver water onto the soilsurface very near the plant or below the soil surfacedirectly into the plant root zone.It is also known as pressurized irrigation system.
NEED OF MICROIRRIGATION SYSTEM Reduce the salinity of soil. to get timeless work.To reduce the evaporation and infiltration.To give sufficient amount of water to make a favorable condition of soil for building up the plant tissue. to get higher production to compete the increasing population of our country. insufficient rainfall, uneven distribution of rainfall.
ADVANTAGES OF MICROIRRIGATION SYSTEMWater saving or water efficiency :- By applying water only where and when it is needed, with less runoff and less evaporation from leaves and soil, the uniform application of water from drip irrigation systems can achieve high water savings.Weed and disease reduction: - Because of limited wetted area from non-spray type of micro-irrigation, weed growth is inhibited and disease incidences reduced.Improved Yield: - Slow and regular application of water and nutrients uniformly to all plants improves product quality and uniformity, and increases yield.Fertilizer Saving: - Fertilizer losses are minimized, reducing fertilizer costs. Labor Saving: - Less labor is required for irrigation, weeding, and fertilizer application compared to traditional production methods.Reduced Cultivation Cost: - Slow and regular application of water keeps an optimum soil-water-air ratio in the soil which is essential for healthy plant growth. It also reduces the need for frequent inter-culturing, weeding, etc.Evaporation and soil erosion are decreased.
DISADVANTAGES OF MICRO IRRIGATION SYSTEMHigh initial cost.Requires some management and maintenance.Clogging emitter and sprinkler nozzle.Salt accumulation near the root zone.Seed germination.Moisture restricted root zone.High skills are required.Short life time due to sun.Wind drift.A stable water supply is needed.
TYPES OF MICRO IRRIGATION SYSTEM
Drip irrigation system.Sprinkler irrigation system.Fogging irrigation system.Bubbler irrigation system.
DRIP IRRIGATION SYSTEMDrip irrigation system: - - It is an artificial application of water to the soil, near the root zone of plant at frequently and slowly using emitter.
CROP GROWN UNDER DRIP IRRIGATION SYSTEMFollowing crops can be successfully grown under drip irrigation system.Orchard crops grapes, banana, guava, orange, mango. vegetables tomato, chilly, capsicum, cabbage.Cash crops cotton, turmeric, strawberry.Flowers roses, jasmine, tulip, mogra.Oil seed ground nut, coconut, sunflower.Forest trees teakwood, bamboo, casurina.
Guava under drip
SPRINKLER IRRIGATION SYSTEMSPRINKLER IRRIGATION SYSTEMSprinkler irrigation system: - - It is a method of applying irrigation water above the soil surface in the form of spray or droplets, similar to the natural rain fall.
BASIC DATA REQUIRED FOR SPRINKLER SYSTEM DESIGNSurvey map of area.Water resource.Soil type.Climatic records.Type of crop.Hydrologic property of soil.Source of energy.Wind speed and direction.Water quality.
FOGGING IRRIGATION SYSTEM
FOGGING OR MISTING SYSTEMIt is the application of water in the form of very fine spray in order to create humidity in the air at low level or over head.There system are generally used in greenhouses to control the humidity and temperature.The flow rate of this system is 10 to 30 l/h and with pressure of 3.5 to 10 kg/cm2.
