Abstract/ Executive Summary:

An experiment was carried out at the Agronomy Laboratory Field, Department of Agronomy, Hajee Md. Danesh Science and Technology University, Dinajpur during the Boro season to study the effect of weed control measures on the yield of BRRI dhan29.The results showed that the experimental field was infested by thirty two weed species belonging to thirteen families. The influence of herbicides at different doses showed significant effects on the weed population. The yield attributes were significantly influenced by weed control measures. Among the different herbicides, highest yield (5.06 t ha^-1) was recorded by the application of Ronstar 25EC. Therefore, application of Ronstar with recommended dose maximized the yield of BRRI dhan29.

Program Area: Crop-Soil-Water Management

Commodity: Chemical weed management

Objectives:

1. To evaluate the weed control efficiency in transplant Boro rice at different doses and asses the effect of different doses of herbicides on yield of transplant Boro rice.

Methodology:

The experiment was conducted at the Department of Agronomy, Hajee Mohammad Danesh Science and Technology University, Dinajpur during Boro season to study the effect of weed control measures and the yield of boro rice BRRI dhan29. The experimental field was a medium high land having sandy loam soil with pH 5.60. The herbicidal treatments of AMCHLOR, RIFIT and RONSTAR bearing with three doses (Lower, Recommended and Higher) were applied in the experimental plots on RCBD design with three replications. h₁ = amchlor 5G, h₂ = rifit 500 EC, h₃ = ronstar 500EC. Doses of herbicide h₁ = T₁, T₂, T₃ (20 kg ha^-1, 25 kg ha^-1, 30 kg ha^-1). h₂ = T₁, T₂, T₃(750 mlha^-1, 1005 mlha^-1, 1250 mlha^-1) h₃ = T₁, T₂, T₃ (1500 mlha^-1, 2010 mlha^-1, 2500 mlha^-1). The data were collected on the following broad steps at different dates as per experimental requirement. Data were recorded on different crop characters viz. Plant height (cm), Number of total tillers m^-2, Number of effective tillers, Length of panicle (cm), Number of spikelet’s panicle, Grain yield, Straw yield etc. The collected data were compiled and tabulated in proper from for statistical analysis. Analysis of variance (ANOVA) was done following single factor RCBD design with the help of a computer package (MSTAT-C).
