A tractor drawn roto drill cum herbicide applicator (RDHA) was developed during 2012-13, at College of Agricultural Engineering, Bapatla. It was developed for adaption of minimum till technology and timeliness of and herbicide application operations. The RDHA was a combination of rotovator, seed hopper (Trough feed type) and rocker sprayer pump. It performs tillage, sowing and herbicide application simultaneously in single pass of tractor. It was found that the total time required for performing the three operations (tillage, sowing and herbicide application) simultaneously with developed RDHA was 3.68 h/ha and 4.61 L /hr which was 26% less when compared with the time required for performing the three operations individually. RDHA consumed 17% more fuel when compared total fuel consumption of individual operations. The RDHA was evaluated for terits seed rate which was observed to be 25.33 kg/ha for paddy and 19.02 kg /ha for maize. The application rate and spray angle were found to be 321.35 l/ha and 36.52â° respectively.
