PERFORMANCE OF SOME TOMATO VARIETIES AGAINST WHITEFLY AND FRUIT BORER

Abstract

The experiment was conducted in the central farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during November to March, 2017 to evaluate varietal performance of tomato against the infestation of white fly and tomato fruit borer. This is the single factor experiment. Ten varieties of tomato T1: BARI Tomato 2, T2: BARI Tomato 3, T3: BARI Tomato 14, T4: BARI Tomato 15, T5: BARI Tomato 16, T6: BARI Tomato 17, T7: Sonali 35, T8: Solar, T9: Bijli 11 and T10: Sonli 12 were used as the experiment materials. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. At 50 DAT the maximum number of white fly plant-1 (27.97) was recorded from T8 (Sonali 35) and the minimum number of white fly plant-1 (19.23) was recorded from T2 (BARI Tomato 3) variety. The highest number of branches, leaves, inflorescence plant-1 was recorded in T2 (BARI Tomato-3) and lowest was recorded in T7 (Sonali 35). The highest percentage of branches, leaves, inflorescence infestation was recorded in T7 (Sonali-35) and lowest was recorded in T2 (BARI Tomato-3). At 85 DAT the maximum number of fruit borer plant-1 (10.70) was recorded from T7 (Sonali 35) variety and the minimum number of fruit borer plant-1 (9.06) was recorded from T2 (BARI Tomato-3). At 85 DAT the highest number of infested fruit plant-1 (4.13) was recorded from T5 (BARI Tomato 16) variety and the lowest number of infested fruit plant-1 (3.12) was recorded from T2 (BARI Tomato-3). Total number of fruit plant-1, individual fruit weight, and weight of fruit plot-1 and yield of different varieties varied significantly due to different variety. The highest yield (53.83 t ha-1) was obtained from T2 (BARI Tomato 3) variety and the lowest yield (47.01 t ha-1) was obtained from T4 (BARI Tomato 15) variety. All varieties were infested by whitefly and fruit borer. But the BARI Tomato 3 (T2) variety is better among 10 varieties regarding more tolerant to the whitefly and fruit borer and resulted higher yield.
