Effect of thio-urea on yield and economics of coriander (Coriandrum sativum L.) varieties under normal and late sown conditions

An experiment was conducted during the rabi season of 2003–04 and 2004–05 to study the effect of thiourea on yield and economics of coriander varieties under normal and late sown conditions. The crop sown at normal sowing time (last week of October) produced significantly higher growth attributes, yield attributes, seed and straw yield and net returns of coriander as compared to late sown. Variety RCr-435 gave significantly higher seed and straw yield and net returns over variety RCr-41. The highest seed yield (14.2 q ha-1), straw yield and net returns (Rs 29,519 ha-1) obtained observed under two foliar sprays of 1000 ppm thiourea at vegetative and flowering stages was significantly higher over one foliar spray of 500 ppm at vegetative stage, seed soaking with 500 and 1000 ppm thiourea and water sprayed control.
