Abstract：In order to investigate the effects of Brassica green manure on flue-cured tobacco production in western Henan province,we conducted a field experiment with three Brassica green manure (rappini,mustard and rape) applications during idle time of flue-cured tobacco production,and conventional cultivation(no green manure) as the control to study the differences of the growth,disease incidence and yield of flue-cured tobacco.The results showed that three Brassica green manure applications significantly increased plant height and maximum leaf area of tobacco,remarkably enhanced the chlorophyll content,photosynthetic rate,transpiration rate,and stomatal conductance compared with the control.Compared with the control,Brassica green manure applications did not significantly affect disease incidence of tobacco mosaic virus,but significantly decreased disease incidence of tobacco root-knot nematode and black shank.The incidence rates of root-knot nematode with rappini,mustard and rape applications decreased by 38.5％,27.5％ and 50.5％,respectively,and the incidence rates of black shank reduced by 47.5％,53.5％ and 56.4％,respectively.Compared with the control,the applications of rappini,mustard and rape also significantly increased the yield,average price and output value of flue-cured tobacco,the yield increased by 8.7％,15.5％ and 24.7％ compared with the control,respectively.In general,compared the effects of three Brassica green manure aplications,rape was the best in promoting the growth and yield of flue-cured tobacco.
