Abstract
The present study is entitled as, “Weed management studies in maize
(Zea mays L.)”, was conducted at Research area of K.V.K. Damla, Yamuna
Nagar (Haryana) under CCS Haryana Agricultural University, Hisar during
kharif season of 2004. The experiment was laid out in randomized block design
in field with 15 treatments of herbicides and three replications.
All the weed control treatments effectively controlled the weed and gave
significantly higher yield than weedy check. Post-emergence application of
glyphosate (1%) at 45DAS with pre-emergence application atrazine (500 g/ha)
provided excellent control of all the weeds till maturity. Pre-emergence
application of prometryn (1000 g/ha) fb glyphosate (1%) at 45 DAS and one
hoeing at 21 DAS fb glyphosate also provided excellent control Dactyloctenium
aegyptium and Cynodon dactylon. Post-emergence application of glyphosate
either with pre-emergence application of atrazine or prometryn gave the grain
and stover yield statistically at par with weed free treatment.
