Bio-efficacy of herbicides on growth and yield of strawberry cv. Chandler

Abstract

A field trial was carried out on weed control in strawberry during 2007-08. Weed control treatments significantly reduced their population and dry matter as compared to weedy check. The lowest weed population and weed dry matter and highest weed control efficiency (WCE) was observed in weed-free check followed by herbicide treatment of oxyfluorfen + napropamide @ 0.60 + 5.00 kg a.i./ha. The strawberry plants attained maximum height (14.82 cm) with a spread (26.26 cm) under weed-free conditions followed by plants applied with oxyfluorfen @ 0.55 kg a.i./ha and polythene mulch treatment. Maximum yield (182 g/plant) was obtained under weed-free plots followed by(179.33 g/plant) under polythene mulch. The yield obtained under weedy check was (106.66 g /plant). Weed control efficiency and weed index was observed in the range (0-100%) and (0.00-41.39%).
