First & foremost suggestion is not to go for the readymade kits, as most often these kits would not suit your requirement.
I strongly suggest a tailor made approach here.
To start with;
A)Please find a model layout based on your PPT attached here
B)Estimate the no of plants/water per plant per irrigation schedule required
C)Estimate water requirement of each zone
D)Size your main line & subline that can carry the required water
E)Drip laterals & emitters would be depending on your plant to plant spacing
F)The motor selection would depend on the total water requirement per schedule, pressure head required (determined after calculating the distance & pressure losses across the main, subline & laterals based on materials used), availability of no of hrs of power etc
Depending on the water quality you may opt for the drip head unit i.e filters, fertigation units etc. The head unit would be near the water source & act as a distribution point where main lines would be controlled by individual valves.You can inturn use check valves to control sublines too.If multiple fertigation units needed, connect the fertigation units individually to the sublines.
Hope this helps!
