Allelopathic Effects of Schima khasiana and Michelia champaca on Germination and Growth of Some Legume and Cereal Crops of North Eastern Himalayan Region

Allelopathic influences of Michelia champaca and Schima khasiana were tested in bioassay on two cereal crops (maize-Zea mays paddy-Oryza sativa), legume food (rice bean- Vigna umbellata soybean- Glycine max). The aqueous leaf extracts fresh dried leaves above tree species suppressed the growth test crops. study revealed that are least toxic to germination, yield various Although, germination paddy soybean was adversely affected by species, however, magnitude toxicity very less which is evident from dry matter production Rice bean maize have been found resistant phytotoxicity. It therefore; well data maize, paddy, rice can be grown successfully proximity khasiana.
