Aims
To measure the effect of plant growth regulants and their interaction with nitrogen on wheat grain yield and quality, in the absence of lodging.
Key messages
Plant growth regulators had no significant impact on wheat grain yield in 2012, at four different sites.
Plant growth regulators can reduce grain yield and quality with incorrect application timing, especially to crops under stress i.e dry, nutrient deficient, frost, waterlogging.
