Abstract
Field experiments were conducted during 2020–21 to assess the performance of high yielding cassava varieties YTP 2 (Yethapur 2) and Sree Athulya. They were compared with traditionally cultivated type called Mulluvadi Local. The trial was conducted at ten different locations of Vellakovil block of Tiruppur district during rabi 2020. The results showed that, YTP 2 recorded maximum plant height (197.21 cm), stem girth (9.78 cm), number of leaves (32.56) and canopy spread (62.36 cm) at harvest. Number of roots (7.78), maximum length of the root (38.05 cm), maximum girth of the root (21.22 cm), root yield (6.38 kg/plant), estimated root yield (41.37 t/ha) and starch content (29.40%) were also highest in YTP 2. In addition, it was highly resistant to cassava mosaic disease. The benefit cost ratio was highest in YTP 2 (2.30) and concluded that, YTP 2 can be recommended for large scale cultivation in Vellakovil block of Tiruppur district.
