Evaluating the effects of manual hoeing and selective herbicides on maize ( L.) productivity and profitability.

The objective of this study was to evaluate maize production and the economic profitability of weed management techniques. Field trials were conducted at the Kasapa farm during the 2021/22 growing seasons using a split-plot design with three repetitions. The main factor was the herbicides applied in pre-emergence alone (2L ha: acetochlor, bentazon, imazethapyr and 60 g ha chlorimuron-ethyl), then mixed (1L ha: acetochlor plus bentazon plus imazethapyr plus 30g hachlorimuron-ethyl), manual hoeing (3-5WAS) including the non-weeding.
