Cassava is one of the most important tropical tuber crops that ensure food and nutritional security in the
developing countries. In India, cassava is cultivated mainly in the southern states viz., Tamil Nadu,
Kerala and Andhra Pradesh. Harvesting is one of the major difficult and labour intensive operations in
cassava cultivation. In India, cassava is mostly harvested manually by hand. This study was attempted to
evaluate the performance of tractor operated Tamil Nadu Agricultural University (TNAU) cassava
harvester with two industrial varieties (H-165 and Mulluvadi) and two commercial planting system
(Mound and Ridge) using six treatments in a randomized complete block design (RCBD). Based on the
field performance trial, the shank length and width of digging blade were modified and then their
dimensions were optimized for better performance. Among the selected treatments, it was found that a
minimum damage of 4.12% was observed for H-165 variety under manual harvesting and a maximum
damage of 9.05% for Mulluvadi variety in mound planting system under mechanized harvesting was
noticed. The tuber spread length was highly correlated with the per centage damage (%) of cassava
tubers. Thus, the tuber spread length is an important agronomical parameter to be considered while
selecting the variety for mechanization of cassava harvesting. This study also confirmed that the ridge
planting system is highly suitable for operating mechanized harvester as compared to mound planting
system.
