The present investigation entitled Effect of plant geometry and nutrition on growth parameters of transplanted ajowan (Trachyspermum ammi L. Sprague) in the red loamy soils of Andhra Pradesh. was carried out at College of Horticulture, Venkataramannagudem, West Godavari district of Andhra Pradesh during Rabi 2017-2018. The experiment was laid out in a factorial randomized block design with 18 treatments replicated thrice. The treatments include plant geometries 30 cm x 20 cm, 45 cm x 20 cm and 30 cm x 30 cm at six fertilizer levels i.e. 75% RDF (15: 30:15 NPK kg hectare-1), 100% RDF (20: 40:20 NPK kg hectare-1), 125% RDF (25: 50 :25 NPK kg hectare-1), 150% RDF (30: 60: 30 NPK kg hectare-1), 175% RDF (35: 70: 35 NPK kg hectare-1), and 200% RDF (40: 80: 40 NPK kg hectare-1).Among the different fertilizer levels and plant geometry number of primary branches (14.90) and secondary branches (59.67), fresh weight (143.67 g) and dry weight per plant (48.67 g) significantly higher in the fertilizer level 200 % RDF with plant geometry 45 cm x 20 cm whereas plant height shows significantly higher (118.67 cm) in the fertilizer level 200 % RDF with the plant geometry 30 cm x 20 cm and plant spread (181 cm2)in the fertilizer level 200% RDF with plant geometry 30 cm x 30 cm, crop growth rate (12.20 g dm2 day-1) at 175% RDF with plant geometry 30 cm x 20 cm but plant population after 30, 60 and 90 days found non-significant.
