Effect of weed control on yield and quality of malt barley (Hordeum vulgare)

Abstract

The experiment was conducted at the Research Farm of the Khalsa
College, Amritsar during Rabi seasons of 2013-14 and 2014-15 to study
the weed control efficacy of different herbicides in barley. Minimum
weed dry weight was recorded in clodinafop (60g) + metsulfuron
(4g/ha), which was significantly lower than isoproturon (936 g) +
metsulfuron (4 g/ha), isoproturon (936 g) + 2, 4-D (500 g/ha), pinoxaden
(50 g/ha), fenoxaprop-p-ethyl (100 g/ha), isoproturon (936 g/ha), hand
weeding and weedy check during both the years. Maximum plant
height, , dry matter accumulation, effective tillers, ear length, numbers
of grains per ear, test weight, grain yield and malt yield were recorded
in clodinafop (60 g) + metsulfuron (4 g/ha ) which was significantly
higher than isoproturon (936 g) + metsulfuron (4 g/ha), isoproturon
(936 g) + 2, 4-D (500 g/ha), pinoxaden (50 g /ha), fenoxaprop-p-ethyl
(100 g/ha), isoproturon (936 g/ha), hand weeding and weedy check
in both the years.
