Application of nitrogen and phosphorus increases seed yield and essential oil of coriander.

 

In field experiments conducted with Coriandrum sativum from 1991 to 1994, N was applied at 0, 20, 30 or 60 kg/ha as urea and P was applied at 0, 15, 30 or 45 kg/ha as single superphosphate. Seed yield and essential oil yield increased with increasing rates of N and P. There was a significant interaction between N and P for essential oil yield but not for seed yield. Total N and P uptake increased with increasing application of N and P. N application increased the postharvest soil organic carbon content and Olsen extractable P, but P application increased only extractable P.
