Suitability of Drip irrigation
Drip irrigation is adopted extensively in areas of acute water scarcity and especially for crops such as Coconut, Grape, Banana, Ber, Citrus, Sugarcane, Cotton, Maize, Tomato, Brinjal and plantation crops. It is suitable to almost 80 crops in different soil and agro climatic conditions.
Advantage of drip irrigation
Drip irrigation offers several advantages over traditional irrigation methods.
- 1 Less weed growth: restricted weed growth to wetted areas only
- 2 Uniform and controlled water distribution closer to plant roots
- 3 Partial soil wetting: only to crop root zone
- 4 Moisture always at or near field capacity in the root zone
- 5 Less fertilizer/ nutrient loss due to localized application
- 6 High water distribution efficiency
- 7 Permits use of poor quality water
- 8 Recurrent irrigation is easily accomplished and has the effect of keeping soil moisture between field capacity and saturation
- 9 Soil factor plays less important role in frequency of irrigation
- 10 Levelling of the field not necessary
- 11 No soil erosion
- 12 Cultural operations are possible even during irrigation Low labour cost
- 13 Possibility of regulating variation in water supply.
- 14 Simultaneous of application water and fertilizer i.e. fertigation.
- 15 Low water delivery rate, low water pressure, precise placement of water.
- 16 Minimum application, field runoff and deep percolation losses.
