Chemical Weed Management, Chickpea, Growth, Weed Dynamics, Yield Attributes,Abstract
A field experiment was conducted at the Research Farm of the College of Agriculture, Banda University of Agriculture and Technology, Banda. The climate of this region is typically semi-arid, characterized by extremes of temperatures during both summers and winters. The experiment was conducted in a randomized complete block design (RCBD) with 10 treatment combinations of pre and post-emergence herbicides. Among herbicides pre-emergence application of Imazethapyr 40g alone or in combination with pendimethalin or oxyfluorfen significantly reduced weed density, and weed dry weight and proved efficient in managing sedge weeds. The highest weed control efficiency recorded at all three stages of crop growth was associated with Pendimethalin 1000g PE fb Imazethapyr 40g PoE. Application of Pendimethalin 1000g PE fb Quizalofop-ethyl 50g PoE markedly influenced the yield and yield attributes of chickpea.
