ABSTRACT

 

Soybean varieties differ in their sensitivity to imazethapyr herbicide damage. In these experiments, we examined the impact of herbicide-imazethapyr spray on the growth and yield of two soybean varieties. Morphological changes resulted from herbicide application, including leaf elongation and formation of large shoots at the cotyledonary node in JS 335 only. Herbicide treatment significantly reduced the vegetative and reproductive growth and yield variables relative to the control (unsprayed with herbicide). The application of herbicide substantively reduced the weed load in soybean. Although herbicide application significantly impacted several growth variables, it had no significant impact on yield. This is the first record from India.
