DETERMINATION THE EFFECT OF DEFOLIATION TIMING ON COTTON YIELD AND QUALITY
This study was carried out for determining the effect of different application times at 40, 50, 60 and 70 % boll opening and untreated plot of the defoliant on cotton yield, earliness and technological properties in Southeast Anatolia Region conditions in Turkey. Maras 92 cotton variety was used as...
