Conventional tillage-land is plowed with a moldboard plow
Minimum tillage-seedbed is prepared only enough so that the seed can make contact with the soil and germinate
No-till-planting seeds directly into the residue of the previous crop
Row crop planters-plant seeds in precise rows with even spacing within the rows
Drill planters-plant seeds in narrow rows at high population rates
Broadcast planters-scatter the seed in a random pattern on top of the seedbed
Date to plant
Germination rate of seeds
Uniformity of seed
Insect and disease control problems
Type of soil
Egyptians used water from the Nile River for irrigation
Chinese and Native Americans used irrigation
Sprinklers-spray water through the air, much like rainfall
Surface irrigation-water gets to the crop by gravity, flowing over the surface of the soil or in ditches or furrows
Subsurface irrigation-supplies water to the roots of crops underground
Mechanical pest controlGenetic control
Cultural pest controlChemical control
Biological pest control
Pulling or mowing weeds
Use of screens, barriers, traps, and electricity
