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 + MULCHING = PRECISION FARMING
Precision farmingPrecision farming(Farming with (Farming with preciseprecise inputs of inputs of
water, fertilisers and other water, fertilisers and other agricultural inputs)agricultural inputs)Drip Irrigation
Delivers Water directly to the Root ZoneTo reduce the Water loss/Over Irrigation as
well as Uniform Water distribution to each plant
Plastic MulchingIt is the laying of a polyethylene(Plastic) cover over the Plantation Area, so as to Control Evaporation loss & Weed Growth…

We Tested for Four different Water Samples (With ECs 3,6,8 & 10 @ 29C) to be pumped through Drip Laterals.
Higher Electrical
Conductivity (EC) of Water

Coefficient of Uniformity ofCoefficient of Uniformity ofDrip Irrigation Drip Irrigation
(Tested with Online Drippers)(Tested with Online Drippers)
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.
