Drip irrigation system

With drip irrigation system, the total production can be about two-three times more than the amount of water we have.  There are two reasons for this.


Irrigation is possible in two to two and a half times the area as compared to other natives.


The constant increase in the required amount of moisture in the root area of ​​the plant increases the yield per hectare.


The main parts of this system are pumps, driving machines, gravel, filter screens, filters, compost tanks, main line, sub main, lateral and drip plastic.  It is especially important to have a gravel filter if the water source is an open well.  Large particles, sesame, lilies, leaves and other wastes in open well water are dissolved in gravel filters.  The gravel filter is made of stainless steel cylindrical tank filled with sand and various gravel.


In this method drip water is given as per the need around the root area of ​​the plant so that the soil stays moist but the roots get the required air as it is not irrigated with water.  This provides adequate water and nutrients to the plants on a regular basis.  The plants get uniform, uniform and as much water as they need.  Watering in the Nikpala or Surface Kayara system does not get air to the roots for the first four days, only water and air can get to the roots for the next seven days.  For the next four days the roots do not get enough moisture due to evaporation and sinking into the soil.  Thus watering every fortnight gives the plant a chance for its healthy growth.  The roots do not get air in the next days and do not get enough moisture in the later days.  So the only solution to the problem of underdevelopment of plants and low production is drip irrigation system.


Advantages


Some of the main advantages of this method can be considered as follows.


Eliminating water consumption due to evaporation and drainage saves 70 to 80 per cent of the water irrigated by this method, which irrigates more than double the amount of water.


Good quality and higher yields are obtained as water is supplied as per the requirement of the crop drop by drop.


The crop ripens early.  Thus the goods can be sold at higher prices than the initial shortage.


The opposite effect arising from salinity in alkaline soils is due to the presence of moisture which makes it possible to take more produce in such soils.


Chemical fertilizers and pesticides can be easily applied in the soil by drip irrigation when the crop needs it.  Fertilizing by dissolving it with water does not extend beyond the plant roots in the soil.


Crops can easily get the nutrients in the soil when needed.  This is because the nutrients are first soluble in water and then absorbed by the roots along with the moisture.  Thus in this method it is possible to retain moisture continuously in the original area.


Good use can also be obtained by efficient use of alkaline (saline) water.


 Irrigation can be done easily without leveling the hilly land.  This also saves the cost of leveling the land.

Soil erosion can be prevented.  In other methods, dhoria or nikpala also costs 5% of the land.  It can be prevented in this method.


10. Very little weeding reduces weed costs.  In addition, the disease spread by weeds can be completely prevented.


 Limits


This method is very expensive and huge investment is made in developing it.  The smaller the distance between the two lines, the higher the cost.  Therefore, this method is not economically viable for ordinary farmers for short distance crops.


 Maintenance


The following maintenance is required for the full investment of the capital investment made behind the drip irrigation system.


Clean the gravel and screen filter every week.


Run the system at the pressure recommended by the company.


To prevent drip jam, soak in water with concentration of 0.6% acid for about 15 minutes every two to three months.


Over a period of two to three weeks, clean each main and submain pipes by pouring water in the opposite direction.
