This was the experiment taken up during training at Central Institute of Agricultural Engineering, Bhopal. The concepts of Precision Farming including Drip Irrigation and plastic mulching have been discussed.

2. Precision Farming
(Plastic Mulching & Drip Irrigation)
Venue of the Experiment:
Central Institute of Agricultural Engineering,
Bhopal
Topics covered:
 Comparison of Chili production with and
without using Plastic Mulching in a Drip
irrigated transplanted field.
 Clogging and Coefficient of uniformity of
Drippers in Drip Irrigation System.

Drip Irrigation
Delivers Water directly to the Root Zone
To reduce the Water loss/Over Irrigation as well
as Uniform Water distribution to each plant
Plastic Mulching
It is the laying of a polyethylene(Plastic) cover
over the Plantation Area, so as to Control
Evaporation loss & Weed Growth…
DRIP IRRIGATION + MULCHING = PRECISION FARMING

DRIP LATERALS AND
PLASTIC MULCH

 Coefficient of Uniformity is Checked before
laying down the Drip laterals.
 Measured the Volume of Output Water at five
different Drippers in a lateral.
 Ten Nos. of Observations taken.
 If Cu found to be irregular, laterals were checked
for repair/replacement of Dripper/Laterals.
 Land preparations made, if necessary.
