The mechanisation of agricultural practices has resulted in increased agricultural productivity in India. As a consequence it seems that, rotary tillage implements are now being projected as important tools in obtaining fine tilth in soil. Even the Indian agriculture can be profitable by increasing land under cultivation, timely farm operation, reduction of cost of operation, adoption of tractor drawn rotavator etc. The rotavator was tested in terms of width and depth of cut, speed of operation, fuel consumption, theoretical and effective field capacity. Also soil parameters like soil moisture content, type of soil, bulk density etc. were studied. The performance of rotavator was evaluated for medium black and trashy soil. The cost of operation of fertile land was found to be 1988 Rs./ha and that of cultivated land was 1668 Rs./ha. It is found that the field efficiency for cultivated land was found to be more than barren land.Keywords

Rotary tillage implements are now projected as important tillage machinery for better seedbed preparation; however, the ordinary rotavator being in line with the tractor center line at the rear cannot be used in orchards due to the hindrance posed by narrow space between the plants. Therefore, the concept of a modified offset rotavator was proposed, which could perform intercultural operation between the plants. The study was conducted to evaluate the performance of the modified offset rotavator in guava orchard of Horticulture Research Center, Pantnagar. It was found that the draft (negative) for the L-shaped blades increased (1203.4 to 1841.4 N) as the forward speed increased (2.0 to 3.0 km/h) with Increase in depth of cut (80 to 120 mm) for the shield kept in the lowered (down) position and fuel consumption was higher 9.93 l/h at given forward speed 3.0 km/h with 120 mm depth of cut. Soil break up (mean mass diameter) resulting from the Impact action of L-shaped blades on soil was found increased (1.05 to 1.95 mm) as the forward speed increased (2.0 to 3.0 km/h). The extent of residue incorporation was the maximum 97.30 % at forward speed 2.0 km/h with 120 mm depth of cut, whereas at higher forward speed 3.0 km/h, field performance index was observed 88.28 %. The minimum area uncovered near the girth was reported 0.143 m2 at higher girth 0.48 m while plant injury at 3.0 km/h resulted due to impact of sensing assembly with plants was found 50 % in form of scratch on the girth.Keywords
