Sugarcane (Saccharum officinarum) is vegetative propagated crop, grown in more than 80 countries.India is the second largest global producer of sugarcane next to Brazil.Maharashtra state plays vital role in Indian sugar industry.The area under sugarcane cultivation in Maharashtra was 10.22 lakh ha with the total cane production of 712.45 lakh tons, average productivity is 69.71 t/ha in the year 2017-18.Sugarcane cultivation is very labour consuming, requires about 3300 man working hours for different operations for its duration.Use of farm machinery helps in labour saving, ensures timeliness of operations, reduces human drudgery, helps in improving quality of work, reduces cost of operation and ensures effective utilization of resources.Considerable mechanization gap was found in usage of farm machinery especially in sugarcane planting, intercultural (weeding and earthing up), harvesting, detrashing and ratoon management.Earthing up plays an important role in maintaining the growth, yield of the sugarcane crop as well as ratoon.Introduction of multitasking implements is a step towards maximizing the economy of farmer in minimum expenditure.Therefore, based on the above facts the tractor operated two row forward reverse rotavator is developed.It is a tillage implement particularly used for inter culturing operation in sugarcane crop.In forward direction, it is used for weeding operation and pulverization in two rows.In reverse application earthing up in sugarcane crop is performed.The developed machine has provision to adjust the working width as per the row to row spacing of sugarcane crop.The height of ridge form after earthing up was 32 cm and its field efficiency was found to be 83.32 and 80.85% for forward and reverse operation respectively.
