Krishi Vigyan Kendra (KVK), Pandirimamidi, DR. YSRHU conducted on farm trials from 2019-20 to 2021-22, in four selected villages involving eighteen farmers covering an area of 4.5 acres. The principal objective of this study was varietal assessment of high yielding tomato hybrids i.e. Arka Abedh (multiple disease resistant) and Arka Samrat (triple disease resistant) for ascertaining and recommending the cultivars best suited for the region. The results showed that tomato hybrid Arka Abhed (T₂) (528.23 q/ha, 564.65 q/ha and 589.78 q/ha) proved to be the best in yield followed by Arka Samrat (T₃) (501.24 q/ha, 538.67 q/ha and 558.75 q/ha) and INDAM - Rashmi hybrid (T₁) (402.72 q/ha, 434.55 q/ha and 455.45 q/ha) for the three consecutive years of the study. The net returns increased steadily in the demonstration plots ranged from Rs. 2,54,261/- to Rs. 3,38,074/- in tomato hybrid Arka Abhed, whereas tomato hybrid Arka Samrat recorded Rs. 2,35,368/- to Rs. 3,13,250/- from 2019-20 to 2021-22. An Extension gap of 125.51 to 134.33 q/ha and 98.52 to 103.30q/ha were recorded in Arka Abhed and Arka Samrat respectively. Technology Index for tomato hybrids observed as i.e. INDAM - Rashmi (13.24%), Arka Abhed (18.65%) and Arka Samrat (30.15%).
