Yaqui Valley 1989-90 wheat crop survey
During the period 8-15 April 1990, I examined 65 wheat crops in the Yaqui Valley, chosen strictly at random over the whole Valley (from Bacum to Bacobampo, and from Lobitos to the Carretera Internacional). I walked into each crop some 100 m and estimated by eye weeds (% of crop biomass), lodging(% of area), sowing date, soil fertility and grain yield.
