Observation Narrow sense heritability for seed yield in peas was 0 to 41 percent.
Intervention effect The observed change from selecting for higher protein was generally less than predicted.
Intervention effect The observed decrease from negative selection for protein was generally greater than predicted.

Intervention effect Pronamide treatments reduced first cutting quackgrass yields in alfalfa.
Intervention effect Pronamide treatments increased first cutting alfalfa yields.

Association Total herbage yield from all cuttings remained constant or slightly increased in dense alfalfa stands after pronamide treatment.
Intervention effect Pronamide applied with potash as the carrier was as effective against quackgrass as pronamide applied in water.
Intervention effect Pronamide treatment increased crude protein concentration in first cutting alfalfa herbage at all locations and years.
