INFLUENCE OF GROWING CONDITIONS ON YIELD AND ESSENTIAL OIL OF CORIANDER DURING YEAR-ROUND CULTIVATION
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 5
Abstract
Coriander (Coriandrum sativum L.) is an important crop for its tender leaves with characteristic flavor used for culinary preparations as well as the seed used mainly in powder form as spice. Protected cultivation in summer days is a possible alternative to farmers to manage external climatic factors, which may affect seed’s germination and plant biomass of coriander. To find out the relationship between growth and development of coriander with microclimate, a study was conducted under open and protected conditions. Result showed a significant negative correlation between maximum temperature (Tmax) with green leaf yield after one cut (r= -0.823*), green leaf yield after two cut (r= -0.862*) and essential oil content of leaf in no cut (r= -0.829*). Besides, essential oil of leaf in one cut was found positively correlated with both maximum relative humidity (RH max) (r= 0.861*) and minimum relative humidity (RH min) (r= 0.431). Significant negative correlation was observed between Tmax and seed yield (r= -0.853*). Interestingly RHmin and seed essential oil was positively correlated (r=0.880**). No correlation was found between Tmax fluctuation and leaf yield. RHmax was positively correlated with green yield after one cut (r= 0.996**) and green yield after two cut (r= 0.962**).
