VARIETAL PERFORMANCE OF CHILLI AGAINST MAJOR SUCKING PESTS

Abstract

The study was conducted at the research farm of Sher-e-Bangla Agricultural University (SAU), Dhaka during the period from May to August 2014 to study the host preferences of sucking pest on different varieties of chillies. The study comprised with eight varieties of the chilli varieties which are- BARI-I, BARIII, Bindu, Balujuri, Augnikonna, Black Lady, Jhal Morich and Surjamukhi. Data was recorded on number of sucking pests/plant at early, mid and late growing stage, fruiting status in terms of healthy, infested fruits and infestation level in number and weight basis, yield contributing characters and yield. Aphid, jassid, white fly, mite and mealy bug were found in all growing stage. The lowest number of aphids/plant was recorded from BARI II and the highest number from Black Lady. At entire fruiting stage, the highest number of healthy fruits/plant (46.40) was recorded from BARI II, while the lowest number (39.20) from Jhal Morich. The lowest number of infested fruits/plant (1.80) was recorded from BARI II, whereas the highest number (3.27) from Black Lady. The lowest fruit infestation/plant (3.74%) was recorded from BARI II, whereas the highest (7.16%) from Black Lady. At entire fruiting stage, the highest weight of healthy fruits/plant (378.52 g) was recorded from BARI II, whereas the lowest weight (283.97 g) from Surjamukhi. The lowest weight of infested fruits/plant (16.29 g) was recorded from BARI II, whereas the highest weight (28.45 g) from Black Lady. The lowest fruit infestation/plant (4.24%) was recorded from BARI II, whereas the highest (8.55%) from Black Lady. The longest plant (95.28 cm) was found from BARI I, while the shortest plant (81.04 cm) from Jhal Morich. The maximum number of fruits/plant (51.73) was recorded from BARI II, while the minimum number (43.07) from Jhal Morich. The highest weight of individual fruit (8.12 g) was found from BARI II, while the lowest (7.15 g) from Augnikonna. The highest fruit yield (17.50 t/ha) was found from BARI II and the lowest (13.07 t/ha) from Jhal Morich.
