Abstract:
The Bhendi Yellow Vein Mosaic Virus (BYVMV) is the most destructive disease causes heavy yield loss to the farmers. Hence, to create awareness about new improved bhendi varieties and to assess the performance of three Bhendi cultivars with special reference to Yellow Vein Mosaic the present study was carried out under On Farm Testing at coastal district of Ramanathapuram, Tamil Nadu. The lesser mean days to 50% flowering of 49.51, 49.71 and 50.89 was recorded with Kashi kranti, Co (Bh) 4 and traditional Bhendi cultivars respectively. The plant height (124.97 cm) was higher in Co (Bh) 4 cultivar, whereas it was 98.77 cm in traditional variety and 95.49 cm in Kashi kranti. The other growth parameters viz., no. of fruits per plant (16.8), fruit length (12.17 cm) and weight (15.31 g) also maximum in Co (Bh) 4 followed by Kashi kranti (11.66 fruits/plant, 9.01 cm and 8.8 g) and traditional cultivar (8.86 fruits/plant, 8.72 cm and 8.66 g). The Nil BYVMV was recorded with Co (Bh) 4 and it was 16% in Kashi Kranti and 12% in traditional cultivar. The highest average yield of 18.99 t/ha was recorded with Co (Bh) 4 followed by traditional variety (12.43t/ha) and Kashi Kranti (11.78 t/ha). Similarly, the highest net return and BCR of Rs. 1,06,420 and 3.33 was recorded with Co (Bh) 4 followed by traditional variety (Rs. 57,440 and 2.36) and Kashi Kranti (Rs. 49,240 and 2.09)
