Effect of Season and Growing Condition on Biochemical and Physiological Parameters of Coriander (Coriandrum sativum L.)

Coriander (Coriandrum sativum L.) is an important spice crop which belongs to the family Apiaceae and originated from Mediterranean Region. This study was conducted at the Department of Spices and Plantation Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during 2017 to study the effect of season of sowing on biochemical and physiological parameters of coriander under two different growing condition viz., open field and shade net (50%) with the variety CO (CR) 4. The experiment was laid out in a Randomized Block Design (RBD) with eighteen treatments replicated thrice. When we see the results, leaf area and leaf area index was high during the month of October in shade condition and September under open conditions. When we see the biochemical parameters like, Nitrate Reductase Activity, Ascorbic acid, SPAD vale and Soluble protein content were not influenced by sowing condition and season of sowing. Hence from this study it can be concluded that, the Physiological characters were influenced by sowing condition and season of sowing but the biochemical characters were not.
