The purpose of this study was to investigate the effect of integrated nutrient management and plant geometry on growth attributes of ajowan (Trachyspermum ammi L. Sprague). For the purposes of the study a field experiment was carried out during the late kharif season of the year 2019-20 at College of Horticulture, Rajendranagar, Hyderabad. The experiment was laid out in a factorial randomized block design with 12 treatments replicated three times. The treatments include four integrated nutrient management levels [INM1 ] 100% NPK (20:40:20 kg/ha) + FYM (12 t/ha) + VC (6 t/ha) + NC (3 t/ha) + AMC (7.5 litres/ha), [INM2 ] 75% NPK (15:30:15 kg/ha) + FYM (12 t/ha) + VC (6 t/ha) + NC (3 t/ha) + AMC (7.5 litres/ha), [INM3] 50% NPK (10:20:10 kg/ha) + FYM (12 t/ha) + VC (6 t/ha) + NC (3 t/ha) + AMC (7.5 litres/ha), [INM4] 100% NPK + FYM (12 t/ha) (Control), at three plant geometries (S1) 30 cm x 10 cm, (S2) 30 cm x 30 cm and (S3) 45 cm x 30 cm. Among the interaction effect of integrated nutrient management and plant geometry on ajowan, maximum plant height (126.49 cm) was recorded at T1 (INM1+ S1), followed by T2 (INM1+ S2) (121.14 cm) and was at par withT4 (INM2+ S1) (119.52 cm), where as T9 (INM3+ S3) recorded minimum plant height (99.93 cm), while more number of primary (14.38) and secondary branches per plant (50.16), maximum fresh (142.51 g) and dry weight per plant (44.28 g) was noticed in T3 (INM1+ S3), while minimum was recorded in T7 (INM3+ S1) and maximum crop growth rate was in T1(INM1+ S1)(12.96 g dm2 day-1), where as T8 (INM3+ S2) recorded minimum crop growth rate (5.10 g dm2day-1).
