Abstract
A technology has been developed for weeding in between wide row crops such as Jatropha and Eucalyptus by using tractor operated rotovator with appropriate modifications in the traction wheels of the tractor. The machine is capable of weeding 0.20 ha/h with 97 per cent weeding efficiency and 83 per cent field efficiency. Cost of replacing the tractor rear pneumatic wheels with iron wheels comes to Rs.14,000/-. Cost of weeding by this technology comes to Rs.1700/ha. When the wide row crops are planted in check row planting (rows in both directions), the equipment can be used for weeding and interculture in both directions.
