Abstract

Herbicide use, which has now become an integral part of the chemical inputs required for weed control in modern agricultural production, have not only contributed to healthy crop growth but also improved farm work efficiency .The experiment was conducted to determine the economy of tillage and herbicide weed control in cassava production during 2021 and 2022 growing seasons at theTeaching and Research Farm, Ladoke Akintola University of Technology, Ogbomoso, (Longitude 8⁰15^”N and Latitude 4⁰ 25^’” E) Oyo State Nigeria. The experiment was a randomized complete blockdesign, replicated three times with split plots arrangement, the treatments were Lagon (1 kg ai/ha), Primextra Gold (3 kg ai/ha), Xtravest (3 kg ai/ha), Atrazine (4 kg ai/kg), Pendimethalin (2 kg ai/ha) and Metolachlor (1 kg ai/ha) herbicide weed control. Hoe weeding at 4, 8 and 12 week after planting and unweeded checks were included to serve as control. Data were collected on sprouting and survival of cassava plants, weed population and biomass, and cassava tuber yields. Partial budgeting was used to evaluate economics of production. Data were subjected to analysis of variance and means compared with least significant difference (LSD 0.05).

Results showed that the herbicide treatments significantly affected both the sprouting and survival of cassava plants, hoe weeding had the least weed density (34.50 m ^-2), Highest cassava fresh tuber yield(63.67 t/ha) was also obtained from hoe weeding. 3 hoe-weeding was the most profitable (N1634000) followed by Primexra Gold (N1511500), Metolachlor (N 1456500), Atrazine (N1262000), Xtravest (N 1196500), Lagon (N 1160000) and Pendimethalin (N1131000) in that order.
