Abstract
The yield of soybeans, an economically important crop worldwide, is substantially reduced by different abiotic and biotic factors, including insect pests. Different insecticides are applied to control soybean insect pests. The application of insecticides may also affect the plants along with the pests. The effects of four insecticides (fenitrothion, etofenprox, thiamethoxam, and lambda-cyhalothrin-cum-thiamethoxam; LT) on the growth and yield of two soybean cultivars over two years were investigated. The plant height (PH), pod number, shoot dry matter without seed (SDWS), total shoot dry matter, seed yield per plant (SYP), harvest index (HI), and hundred-seed weight significantly varied with the insecticides. However, the primary branch number was not significantly affected by the insecticides. Significant interactions between the year and insecticide, except for the SDWS and HI, indicated that the growing environment also affected the influence of the insecticides. The PH was significantly tall in the thiamethoxam (50.07 cm) and short for the LT (46.66 cm) application. The SYP was significantly high for the LT (20.51 g) and low for the fenitrothion (11.51 g). This study showed that the type of insecticide could significantly affect the plant growth and yield of the soybean.
