A field experiment was conducted at Olericulture Division, Horticulture Research Center (HRC) of Bangladesh Agricultural Research Institute (BARI), Gazipur, Bangladesh, during the period from October 2017 to April 2018 to study the effect of grafting compatibility of different rootstock with different scion for eggplant. The 24 grafted treatments (6 scion × 4 rootstock) and 6 non grafted treatments of eggplant (Solanum melongena L.) showed significant variation in grafted and non-grafted different characters studies. Thirty treatment combinations showed significant better yield, fruit and shoot borer infestation. Among the thirty treatment combinations grafted on different rootstock like S. sisymbriifolium, BARI Begun 8, BARI Begun 10 and EgN 203 with several scions viz., BARI Begun 4, BARI Begun 9, BARI Hybrid Begun 2, BARI Hybrid Begun 4, BARI Bt Begun 2, BARI Bt Begun 4. The highest marketable fruit in grafted treatment was observed in T4 (28.97 fruit/plant) followed by in T1 (26.9 fruit/plant), in T5 (26.47 fruit/plant), while average fruit weight in grafted treatment was observed (321.47in T6 followed by T18 (266.47 g) T12 (236.47), T24 (201.47 g). The highest fruit length in grafted treatment was observed in T5 (16.7 cm) followed by T17 (16.3 cm), T3 (15.9 cm), T13 (15.9 cm), T23 (15.7 cm), while the highest fruit diameter in grafted treatment was observed in T24 (10.23 cm) followed by T12 (10.13 cm). The lowest infestation by fruit and shoot borer infestation was observed in T7 (4.93%), while the overall infestation (%) rate was 4.33–27.37. The significant highest fruit yield (36.77 t/ha) was produced by T6 closely followed by T1 (36.43 t/ha), T13 (35.35 t/ha), T4 (34.56 t/ha), T5 (32.69 t/ha), T19 (30.69 t/ha), T17 (30.07 t/ha), while lowest fruit yield was recorded (12.37 t/ha) was produced by T26 followed by T8 (15.32 t/ha), T28 (15.61 t/ha). Among the grafted and non- grafted eggplant treatments, T6 (36.77 t/ha), T1 (36.43 t/ha), T13 (35.35 t/ha), T4 (34.56 t/ha), T5 (32.69 t/ha), T19 (30.69 t/ha), T17 (30.07 t/ha) were the highest yielder. In compare of rootstock, better performance was observed in BARI Begun-8 rootstock while grafted with 4 scions viz., BARI Begun-4 (36.43 t/ha), BARI Hybrid Begun-4 (34.56 t/ha), BARI Bt Begun-2 (32.69 t/ ha), BARI Bt Begun-4 (36.77 t/ha). However, the study was for one season experiment. So, to draw a conclusion it is needed to conduct this experiment in another season.
