A two-year field experiment was conducted at experimental farm, Faculty of Agriculture, Kafrelsheikh University, Egypt during both 2015/2016 and 2016/2017 successive winter growing seasons to the effect of some pre and postemergence herbicides on physiological and histological characters, productivity and quality of carrots (cv. "Tokita"). Each experiment included nine weed control treatments which consists of four herbicides (three herbicides used as pre-emergence i. e. prometryn 312.5 or 625g; linuron 112.5 or 225g and pendimethalin 425 or 850 g a. i./fed. while the other herbicide i. e. fluazifop-p-butyl 62.5 g was used as post-emergence, and hand hoeing twice (at 30 and 45 DAS) and weedy chick. Significant differences on chlorophyll content (chi. a, b and total) were induced during the both seasons. Prometryn gave the highest value of chlorophyll a. Pendimethalin gave the highest value of RWC and least of LWD. The highest values of carrot root half diameters and cortex tissue thickness were detected by pendimethalin treatment. All tested herbicides gave the highest values of quality characters in carrot roots, followed by hand weeding of the annual weeds. [ABSTRACT FROM AUTHOR] |
