Drip irrigation

Drip water system includes dripping water onto the dirt at low rates (2-20 litres/hour) from an arrangement of little breadth plastic channels fitted with outlets called emitters or drippers. Water is connected near plants with the goal that exclusive piece of the dirt in which the roots develop is wetted, dissimilar to surface and sprinkler water system, which includes wetting the entire soil profile. With drip water system, water applications are more regular (normally every 1-3 days) than with different techniques and this gives an ideal high dampness level in the dirt in which plants can prosper.

Drip water system framework releases water to the crop utilizing a system of mainlines, sub-mains and sidelong lines with outflow focuses dispersed along their lengths. Each dripper/emitters, opening supplies a deliberate, decisively controlled uniform use of water, supplements, and other required development substances straightforwardly into the root zone of the plant.

Water and supplements enter the dirt from the emitters, moving into the root zone of the plants through the joined powers of gravity and capillary. Along these lines, the plant's withdrawal of dampness and supplements are recharged very quickly, guaranteeing that the plant never experiences water stress, subsequently improving quality, its capacity to accomplish ideal development and high return.


Major Components of Drip Irrigation System

1) Pump station takes water from the source and gives the correct weight to conveyance into the pipe framework.

2) Control valves control the release and weight in the whole framework.

3) Filtration framework cleans the water. Basic sorts of the channel incorporate screen filters and graded sand filters which expel fine material suspended in the water.

4) Compost tank gradually includes a deliberate measurement of manure into the water, while irrigating fields. This is one of the significant points of interest of drip water system over different techniques.

5) Mainlines, sub mains and laterals supply water from the control head into the fields. They are normally manufactured using PVC or polyethene hose and ought to be covered in soil because they deteriorate chemically under the exposure of solar radiation. Parallel funnels are normally 13-32 mm width.

6) Emitters or drippers are gadgets used to control the release of water from the horizontal to the plants. They are normally dispersed more than 1 meter separated with at least one Emitters utilized for a solitary plant/tree.A wide range of Emitters outlines has been created as of late. The premise of configuration is to deliver a Emitters which will give a predefined steady release which does not differ much with water pressure changes and does not obstruct easily.

Not at all like sprinkler water system, drip water system just wets some portion of the dirt root zone. This might be as, low as 30% of the volume of soil wetted by alternate techniques. The wetting designs which create from dripping water onto the dirt rely upon release and soil class.

Just piece of the root zone is wetted it is as yet essential to meet the full water needs of the cultivated plants. It is here and there suspected that drip water system spares water by decreasing the sum utilized by the harvest. This is not valid. Yield water utilize is not changed by the strategy for applying water. Harvests simply require the appropriate sum of water for good development.

Drip water system is not a substitute for other demonstrated strategies for the water system. It is simply one more method for supplying water. It is most appropriate to regions where water quantity is negligible, where water or workers are costly, or where high esteem crops require more number of water applications.

Potential points of interest of Drip Irrigation 

Enhanced water utility
Water necessities can be decreased with drip water system over conventional one in spite of the fact that the water savings, obviously, rely upon the product, soil, ecological conditions and the achievable on-cultivate water system proficiency. Essential purposes behind water savings incorporate accuracy water system, diminished surface dissipation, diminished water system spillover from the field and controlled profound permeation misfortunes beneath soil root zone.

Better plant development and yield 
Under drip water system, soil water content in the dynamic segment of the plant root zone remains genuinely steady since water can be provided gradually at a controlled rate. Here, the aggregate soil water potential, soil air circulation, fewer plant diseases and confined plant root development.

Increased effectiveness of fertilizer utilization
Drip water system offers significant adaptability in fertilization. Continuous application of plant supplements along with the irrigation water appears to be beneficial for higher crop yield.

Reduced weeds
Since weed invasion relies upon soil dampness content, drip water system diminishes weed invasion because of restricted wetting of root zone as it were. Critical diminishment in weed biomass was seen in drip water system plot when contrasted with surface flooded plots

Saving of labour

Drip water system can be effortlessly automated where labour is constrained or costly. fewer labour expenses and more prominent productivity is accomplished.

Five Layer Shri Palekar Ji Model - 36*36 model for full 1 acre

Huge trees, for example, Mango, Jack-fruit, Jamun, and Amla ought to be planted 36 feet separated. Guava, Chikku, Lemon and Pomegranate saplings can be planted in the middle of the mango plants at a separation of 18 feet. Papaya, Drum-stick, Banana that involve lesser space ought to be planted in a space of 9 feet between the second arrangement of trees recorded previously. The above plants ought to be planted along a similar column over the plot of land leaving space to develop a single assortment of vegetables, millets and so forth on each bed. separate 1 section of land into a break even with squares of 36ft X 36ft. In each piece of 36 ft x 36 ft ( which is additionally separated into four 9ft X 9ft sub-squares) We can grow around 170 trees, in that 9ft x 9 ft part of the land (one sub-square). Plant 1 Banana Tree, 4 Arecanut Trees, 4 Black pepper Creepers getting on Arecanut trees, 2 Coffee Plants, 2 Glirsedia Trees, 2 Venella Creepers hopping on Glirsedia trees

Stone pole fencing Vs Cement pole fencing Vs Iron pole Fencing

Which is best Fencing? (Stone Vs Cement Vs Iron pole Fencing) Height: If your main concern is to protect your farm from theft, above 10 feet height poles required, which stands 8 feet above ground and 2 feet below ground. Size: 4Inch * 6Inch average pole dimension with 8-10 feet length. Barbed wire from TATA wiron Durability: Stone poles are much more durable than cement or iron. Cement poles starts crumble, iron poles often leads to damage due to rust. Especially poles used to support other poles used in corners or usually called as cross pieces must be strong. Only stone poles give sufficient support without damage. Weight: Stone poles have good weight when compared to cement or iron, so it is not easy to theft by a single person. Whereas Iron poles are easy to lift and carry. Distance: Ideal distance between pole to pole is 8 feet. Even in case when the fence wire sags after some period, it can be re-tightened. If distance increases there will be problem with fence wire. Suppor

Want more flowering for fruit trees? Learn the concept of Smudging !!

Is your tree is lazy to give fruits? Is your tree stubborn to bear fruits? You can make your tree listen to you., how? SMUDGING... Smudging is concept of giving smokey fire to tree, branches and leaves. Some of old aged people know this concept very well, it was slowly perished after potassium nitrate/paclobutrazol came into existence which will make tree to induce flowers and bear fruits. Smudging is simple, gather dried material like leaves, branches, peels, husks etc. Identify air movement, burn dried material. With the flow air into you farm smoke will spread to all trees. Or Keep dried material under the tree and slowly start fire the smoke will spread to the tree. If you want more smoke add some green leaves like Neem or Moist organic material. Best time to do smudging is early morning where air movement is very low and smoke will spread evenly. This need to be done every morning until tree induce with flowers. For Example, Mango trees will start flowering in the months of SEPTE
