Seed yield and quality of coriander (Coriandrum sativum L.) as influenced by seed priming
Abstract: Seed priming, a controlled hydration process, is a simple and cheap technology to the farmers for better germination of seed ensuring a good yield and quality.An experiment was conducted to evaluate the effects of different priming media, and duration on seed germination, growth, yield and essential oil content of coriander at the Horticultural Research Station, Mondouri, West Bengal.There werethreedifferent concentrations of chemical (KH2PO4) viz., 3-, 2-,1% and control (distilled water) with three different duration of soaking viz., 12-, - 16- and 20 hrs.Seed priming with KH2PO4 has significant influence on plant height of coriander.Maximum number of primary branches per plant (7.0), number of secondary branches per plant (12.3), maximum germination (91%), were recorded with 1% KH2PO4 for 20 hrs. 3% KH2PO4 for 12 hrs was found to produce maximum test weight (13.0 g),whereas, seed priming with 1% KH2PO4 for 20 hrs out-yielded all other treatments resulting in the highest number of umbels per plant (23.3),umbellets per umbel (5.7), seed per umbel (38.4), seed yield per plant (3.5 g), seed yield per meter square (15.0 g), projected seed yield (13.5 q ha-1), respectively.It may be concluded from the results that to obtain higher germination, seed yield and essential oil of coriander, seeds should be treated with 2% KH2PO4 as seed priming chemical for 20 hrsunder this Gangetic alluvial region as revealed from the result.
