Abstract: The present investigation entitled on “Influence of integrated nutrient management and plant geometry on quality of ajowan (Trachyspermum ammi L. Sprague) in Southern zone of Telangana” 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 thrice. 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 quality parameters, essential oil content was found significantly more with T₃ (INM₁+ S₃) (3.26) and was at par with T₂ (INM₁+ S₂) (3.19) while, the lowest was recorded in T₇ (INM+ S₁) (2.02). The highest protein content was observed in T₃ (INM₁+ S₃) (19.76), followed by T₆ (INM₂+ S₃) (18.30) while, the lowest was recorded in T₇ (INM₃+ S₁) (12.61).
