ABSTRACT
EFFECT OF SOIL DESINFECTION WITH METHYL BROMIDE IN THE WHEAT MONOCULTURE YIELD TRIAL AT THE EXPERIMENT STATION LA PLATINA IN 1977

The effect of soil desinfection with Methyl Bromide was analysed in 1977 in the wheat monoculture experiments carried on at the Experiment Station La Platina, Santiago, Chile. Every year, since 1963, wheat was sown in each plot. About 40% of yield increases was observed in the highly fertilized as well as in the non fertilized plots, due to soil desinfection.
These differences were not influenced by the hectoliter or the 1,000 grains weight. but they were related to the number of produced grains.
