Abstract :

In order to evaluate the effects of green manure and manure on some quantitative and qualitative characteristics, Dracocephalum Moldavica L, were tested in a Split-plot design, a completely randomized block design with four replications at the research farm of west Azarbaijan Agricultural Research Center in during the years 2011-2012. Main factor consisted of four types of green manure (Secale montanum, Trifolium Pratenes, Medicago sativa and Lathyrus sativus .L) and sub factor 5 types of manure ( 0 t/ha mannure (control), 40 t/ha mannure, nitroxin+ 1/3 manure, nitroxin+ 1/2 manure and nitroxin+ 40 t/ha mannure). The results indicated, that the effect of green manure and manure with nitroxin on leaf dry weight, grain yield, biological yield and harvest index, at the 1% level and on the thousand grain weight at the 1% level were statistically significant. The interaction of two factors showed that the highest amount of grain yield was related to the Secale montanum green manure in nitroxin+ 40t/ha mannure (2984 kg/ha) and the lowest amount of grain yield was related to Secale montanum green manure in the control of manure with nitroxin (1227/75 kg/ha). Also, maximum and minimum biological yield were obtained as affected by Medicago sativa green manure in in nitroxin+ 40t/ha mannure (17520 kg/ha) and in Secale montanum green manure in the control of manure with nitroxin (12580 kg/ha), respectively.
