Influence of integrated nutrient management and plant geometry on quality of ajowan (Trachyspermum ammi L. Sprague) in Southern zone of Telangana

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).
