1. An agricultural seeder for research plots, comprising:
a front gang of planting units;
a rear gang of planting units spaced a distance behind said front gang of planting units;
a first metering system for metering seed for at least one of the planting units in said front gang of planting units;
a second metering system for metering seed for at least one of the planting units in said rear gang of planting units; and
a controller that receives a tripping signal from a tripping system and causes said first and second metering systems to trip at different times to compensate for the distance between said front and rear gangs of planting units so that starting and stopping locations for seed metering for the front gang of planting units is laterally aligned with starting and stopping locations for seed metering for the rear gang of planting units, thereby creating aligned alleyways between plots in a field.
