The germination was found to be decreasing with increase in leachate concentration of all the test crops. Invariably there was a decrease in shoot length, root length and vigour index with increasing leachate concentration of Radish and Mustard, however, the root length and number of secondary roots were observed maximum at 20% leaf leachate concentration in case of Radish and 10% in case of Mustard. The shoot length of French bean was recorded maximum at 30% leaf leachate, whereas root length and vigour index was maximum at 10%, number of secondary root was maximum at 50% leaf leachate concentration.. 收起
