Performance evaluation of power operated wetland paddy weeder in Odisha


C Chanakyan, Dr. SK Mohanty

Weeding is one of the most laborious, costly, time consuming and drudgeries operation in the paddy cultivation. The mechanical power weeder has been promoted to reduce the drudgery, time and cost of operation. The study was conducted to evaluate the performance of mechanical Paddy Power Weeder. The weeding was done 35 days after transplanting in the variety of Swarna at 25 cm row to row spacing during Kharif season in the Central Farm of Orissa University of Agriculture and Technology in sandy loam soil. The various mean performance parameters such as Speed of Operation, Effective field capacity, Field efficiency, Weeding efficiency, Plant damage and Fuel consumption was observed to be 1.65km/h, 0.065 ha/h, 78.9 percent, 84.8 percent, 4.12 percent and 16.9 l respectively. The mean physiological parameters such as working Heart rate, Oxygen Consumption Rate, Relative Cost of Work Load and Energy Expenditure Rate observed to be 139 beats/min, 1.13 l/min, 55.9 percent and 23.78 kJ/min respectively. The Body Parts Feeling Discomfort Score of the subjects using a 10 point scale was observed to be maximum in right and left foot, right and left leg, right and left palm, right and left elbow.
