Field evaluation of different machineries was carried at Central Coffee Research Institute (CCRI) and Coffee Research Sub Station (CRSS), Chettalli during the year 2012-16. Results of field evaluation on different spaying system indicated that significantly higher field efficiency was observed with Multi Utility Track Vehicle spraying with 4 spray lance (0.557 ha per hour) and it was on par with Centralized Spraying System with 14 spray lance (0.510 ha per hour). Lower field efficiency was observed with power tiller spray system (0.410 ha per hour) with 8 lance. Similarly, the labor requirement for Multi Utility Track Vehicle system was less (9 labors per day) as compared to Centralized Spraying System (28 labor per day) and PT (16 labor per day), which resulted in labor cost savings to the extent of 211% as compared to Centralized Spraying System. Mechanical weed cutter was found to be more efficient and economic in terms of cost (Rs. 829 per acre) over manual weeding (Rs. 2800 per acre) and chemical weeding (Rs. 1075). Man days utilized for mechanical weed cutter was also much lesser (1.5 per acre) than manual weeding (10 per/acre) and chemical weeding (3.3 per/acre) respectively. Under the same trial, regeneration of weeds was more in manual weeding compared to mechanically weeding. Significantly higher number of pits (150 pits/man/day) with mechanical pit digger was observed as compared to manually (75 pits/man/day). Therefore use of small machineries in existing coffee plantations of India it would greatly improve the efficiency of field operations and reduce the labour requirement.
