Wheat stand establishment behaviour was studied in different cropping systems under rainfed conditions, during 1992-
94. On the basis of wheat emergence (rn") and emergence rate index, two distinct groups of cropping systems were
observed. The first group included fallow-wheat, mashbean-wheat, mungbean-wheat and cowpea-wheat systems whereas
the second included maize-wheat, sorghum-wheat, millet-wheat, sunflower wheat and soy bean-wheat systems. Wheat
stand establishment was significantly (P<0.05) higher in the first group than in the second group. In Rabi 1992-93 wheat
emergence was completed in a short period and emergence rate index was higher than that for 1993-94 due to dry weather.
Overall, there was significantly (P<0.05) better residual soil moisture (0-15 em layer) in fallow-wheat, mashbean-wheat,
mungbean-wheat and cowpea-wheat cropping systems than other systems under study during both the years.
