For oilseed rape crops, many authors have shown that the radiation use efficiency (RUEa) varies within a wide range, from 1 to 4 g MJ − 1 of S PARa according to developmental stage
For other crops SMN s were similar to those reported by Harrison (1995), albeit SMN s at TE and RO following winter wheat were no greater than average despite below-average
The 12 papers in this issue of the Journal give a cross cut of research addressing different hierarchical levels and different aspects and objec- tives of agriculture,
This study compared corn ( Zea mays L.) with annual Italian rye-grass ( Lolium multiflorum Lam) intercropping and corn monocrop systems under three controlled drainage levels
Except for 1993 at l’Assomption interrow tillage plus cover crop treatments had consistently lower weed biomass when compared to the weedy control.. Most of the weed control was due
Corn grain yield was generally not a ff ected by any intercrop treatment, although in 1993 some simultaneously seeded treatments resulted in decreased yields.. Soybean grain yield

Seed yield, nitrogen and sulfur uptake, glucosinolate (GLS ) and oil contents of spring oilseed rape grown in pot experiments... only been observed when applied with slurry at
