Abstract

Abstract Strawberry ( Fragana × ananassa Duch. cv. Surecrop) plots fumigated with Vorlex (a mixture of methyl isothiocyanate and dichloropropanes-dichloropropenes) averaged 1148 kg per ha more berries than nonfumigated plots. Granular urea applied to the soil before planting was as effective in increasing fruit yield as an application split before planting and in August of the first growing year. Yield increased as the amount of Ν applied increased, but was not influenced by Ν source.
