Following particulars were recorded from agriculture Land growing where:-

• FC = 20%
• PWP = 8%
• Permissible Depletion of available moisture = 50%
• Root Zone Depth = 2m
• Dry unit weight of soil =1400 kg/m^3
• Effective Rain fall = 20mm.
• Cu = 5.6mm/d
• Find NIR and FIR if application losses are 10%. Also,Find the Frequency of Irrigation.

$$As, N I R=C I R+\underbrace{L R+P S R}_{0} $$ Assuming leaching Requirement and Pre-sowing Requirement to be Zero, $$ \text { NIR }=C I R=C u-\text { Peff } $$

• Depth Required to the raised to satisfy consumptive use $=1.4 \times 2 \mathrm{~m}× 0.06 $ $=0.168 \mathrm{~m}$
