Citrus is highly sensitive to saline water. So what is the minimum threshold limit for salt levels in the irrigation water to be used for irrigation of kinnow orchard.
Block buster success of kinnow in northwestern India is an indication of tolerance level against saline irrigation water , but surely its detrimental against saline water having SAR beyond 6 and RSC beyond 1.5 meq/ litre...depending upon soil texture and presence of absence of subsoil calcareousness....
Dear Manish
The tolerance threshold of citrus to salinity is about 1.2-1.5 dS/m.
The tolerance to salinity is genotype dependent. Then, it is necessary to know the nearest rank for Kinnow, assuming that thw wide range for citrics is that signaled by Seied.
It is partially convincing. Worldwide rough lemons are considered universally salt sensitive rootstock..Perhaps the use scion involving willow mandarin and king mandarin augers well with Bili Kichli , another strain of rough lemon rootstock...
