Assessment of germination and feasibility of hydroponic growth of onion by four common water sources from Barishal region, Bangladesh

Four common water sources of Barishal region near to Bay of Bengal are Kirtonkhola, Andarmanik, Kuakata and available ground water. Based on salinity and agricultural purposes, Kirtonkhola and ground water are a source of fresh and brackish water, respectively, while Andarmanik and Kuakata are considered as saline water sources. Performance of onion seed germination by Kirtonkhola and ground water was best than other two sources. But in hydroponic growth observation, only ground water gave best result in case of new roots and shoots development from mature onion without adding any nutrients or growth hormones.
