cotton: Artificial defoliation in cotton phenology

Description Usage Format References


Cotton production can be drastically reduced by attack of defoliating insects. Depending on the growth stage, the plants can recover from the caused damage and keep production not affected or can have the production reduced by low intensity defoliation. In order to study the recovery of cotton plants (Gossypium hirsutum) in terms of production, Silva (2012) conducted a greenhouse experiment under a completely randomized design with five replicates. The experimental unity was a pot with two plants and it was recorded the number of cotton bolls at five artificial defoliation levels (0%, 25%, 50%, 75%, and 100%) and five growth stages: vegetative, flower-bud, blossom, fig and cotton boll.
