- Abstract
Three possible sources of field contamination by weed seeds were studied during 1983-86 in two areas of Fars Province, Iran. These sources were crop seed, irrigation water and sheep manure. Manure was found to be the most important, adding almost 10 million seeds ha-1 at each application. Farmer-saved seed of wheat, the main crop of the area, added an average of 182,000 weed seeds ha-1. Irrigation water added no more than 120 seeds ha-1, but was able to carry seeds over long distances without affecting viability.
