SCHEDULING OF IRRIGATION

IRRIGATION

It is a practice that aimed that the supplemant of the water by both of natural rainfall and irrigation(artificial source) to ensure the favourable moisture regime in the soil to get higher yield.

SCHEDULING OF IRRIGATION

Technique used to determine the quantity and time of  irrigation, so that optimizing the crop yield with the higher water use efficiency leeds to the soil minimum damage.

CRITERIA FOR SCHEDULING OF IRRIGATION

The criteria depends upon the crop to crop and place to place, some of them are...

• Cumulative pan evaporation (CPE)
• IW : CPE Ratio
• Available soil moisture
• Soil water-stress
• Growth stages
• Canopy temperature
• Leaf water potential
• Use plant indicator
• Cell sap concentration
• Spectral reflectance(canopy) by remote sensing.
