Abstract/ Executive Summary:

Performance of herbicides-Ronstar (Oxadiazon), Logran (Triasulfuron), Lintur (Triasulfuron + Dicamba) and Setoff (Cinosulfuron) were compared against no weeding in three wheat varieties (Kanchan, Akber and Protiva). Ronstar, Lintur and Setoff were applied as pre-emergence while Logran as both pre and post emergence. Herbicides reduced weed growth and significantly increased grain yield of wheat. Application of either Logran as pre or post emergence or Ronstar as pre-emergence effectively controlled weeds and produced 43-46% higher grain yield of wheat.

Keywords: Pre emergence, Post emergence, Herbicides, Wheat

Location: BARI HQ, Gazipur

Start Date: 05-11-1999

End Date: 31-03-2000

Program Area: Crop-Soil-Water Management

Commodity: Chemical weed management

Objectives:

The study was undertaken to select the effective herbicide for weed control in wheat field

Methodology:

The experiment was laid out in split plot design with three replications. Three wheat varieties (Kanchan, Akber, Protiva) were used in the main plots and four herbicides (Ronstar, Logran, Lintur and setoff) with pre and post emergence application were assigned in the sub plots. Efficiency of herbicides were tested against no weeding. The unit plot size was 5 m x 4 m. fertilizers at the rate of 100-60-40 kg/ha of N, P₂O₅ and K₂O were applied. data on yield and yield contributing parameters were analyzed statistically and mean separation was done by Least Significantly Difference Test.
