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
[INM
1] 100% NPK (20:40:20 kg/ha) + FYM (12 t/ha) + VC (6 t/ha) + NC (3 t/ha) + AMC (7.5 litres/ha), [INM
2] 75% NPK (15:30:15 kg/ha) + FYM (12 t/ha) + VC (6 t/ha) + NC (3 t/ha) + AMC (7.5 litres/ha), [INM
3] 50% NPK (10:20:10 kg/ha) + FYM (12 t/ha) + VC (6 t/ha) + NC (3 t/ha) + AMC (7.5 litres/ha), [INM
4] 100% NPK + FYM (12 t/ha) (Control), at three plant geometries (S
1) 30 cm x 10 cm, (S
2) 30 cm x 30 cm and (S
3) 45 cm x 30 cm. Among the quality parameters, essential oil content was found significantly more with T
3 (INM
1+ S
3) (3.26) and was at par with T
2 (INM
1+ S
2) (3.19) while, the lowest was recorded in T
7 (INM+ S
1) (2.02). The highest protein content was observed in T
3 (INM
1+ S
3) (19.76), followed by T
6 (INM
2+ S
3) (18.30) while, the lowest was recorded in T
7 (INM
3+ S
1) (12.61).
