Effects of different herbicides on post-harvest behaviour of chrysanthemum (Chrysanthemum species L.)

Abstract

Weeding is an important operation for chrysanthemum cultivation, which can combat a huge loss in terms of growth and productivity particularly during rainy season. The present experiment was carried out at Horticultural Research Station, Mondouri, B.C.K.V during 2014-15 to find out the effects of herbicides on weed control, plant growth, flowering and post harvest behaviour of chrysanthemum cv. Bidhan Tarun. The experiment consisted of three pre-emergence herbicide, two post-emergence herbicide; three hand-weddings at 25, 50 and 75 days after planting (DAP), weed free check and weedy check (Control). Among the treatments applied Pendimethalin, pre-transplanting pre-emergence @ 1.0 kg a.i./ha followed by hand weddings at 25 and 50 DAP showed better results to suppress the weeds, and results in higher plant growth, flowering, better post-harvest life and consumers acceptability.
