Title

Lodging: Significance and preventive measures for increasing crop production

Seema Dahiya; Sandeep Kumar; Harender Harender; et al. International Journal of Chemical Studies 2018

Other claims from this paper (6)

Observation Cereals are more prone to the effects of both root and stem lodging.
Observation The affected plant becomes weaker and tends to earlier seed production.
Observation Lodging lowers crop yield and nutrient content.
Observation Yield is more affected when lodging occurs at the ear formation stage of the crop.
Observation Stem lodged plants are harder to harvest and there is more waste.
