Abstract

Sowing dates, flowering dates and yields of barley of more than 500 sample plots (20 x 20 m) in Spain have been investigated. Data of the seasons 1993-1994, 1994-1995 and 1995-1996 have been studied. The association between sowing dates, rainfall and soil moisture status has been tested. For rainfall, observed and interpolated data were used. Soil moisture estimates were retrieved from scatterometter data of the European remote sensing satellites (ERS). Analysis of the sowing date demonstrated that sowing is associated with the expected beginning of the rainy season. Variation in sowing dates as a result of variation in rainfall could not be demonstrated. Yield variance analysis, grouping yield by sowing date and by flowering date, demonstrated no significant effect of sowing and flowering date on yield.
