In this study the performance and cost-economics were compared for maize seed. During the study it was found that the mean draft requirement measured during experiment was 384.17 N with an average power output of 0.158 kW/ h. The average speed of operation of the planter was found to be 1.46 km/h. The average seed to seed distance was 30 cm and average row to row distance is 45 cm. The depth of seed placement was 6 cm and actual seed rate observed was 13.2 kg/ha. The theoretical field capacity was 0.127 ha/hr

In India, area under cultivation is about 159.7 million ha. 68% of the total net sown area comes under dry land cultivation, spread over 177 districts. As farmers turn increasingly to multiple cropping systems to boost their incomes and meet increased demand for their produce, the time available for seedbed preparation has decreased considerably.

The side-shift offset rotavator was a newly introduced implement in the field of interculture operations, especially for the orchard crop. The commercially available implement was equipped with J shape soil cutting blades. Those blades were replaced with L shape blades due to their undesirable outcomes. The testing was carried out separately for both types of blades at a fixed tilling depth of 9.6 cm. In this study, the type of cutting blade, kinematic parameter and soil moisture were the considered as the explanatory parameters.
