Grain yield of wheat and some causes of its variation at different technological levels of production

, : Grain yield of wheat and some causes of its variation at different technological levels of production. Investigaciones Agronomicas, Centro de Investigaciones Agricolas "Alberto Boerger" 5(1): 41-46

Factors affecting wheat grain yields over 13 years including high or low rainfall, sowing date and diseases at 3 technological levels, an experimental station, seed certification farms and ordinary farms, are analysed statistically and the results discussed.

Twenty wheat genotypes were evaluated in Maracai, Itabera and Campinas, Sao Paulo, Brazil, in the 1994/95 season. The genotypes showed differences in yield among sites. Cv. IAC 289, IAC 340 and BR 18 gave the highest grain yields, but did not diff...
