Abstract
An experiment was conducted during late kharif season of 2019-20 at College of Horticulture, Rajendranagar, Hyderabad, to find out the influence of integrated nutrient management and plant geometry on nutrient uptake of ajowan (Trachyspermum ammi L. Sprague) in the Southern zone of Telangana. 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, INM2, INM3 and INM4) and three plant geometries (S1, S2 and S3). Results showed that available nitrogen (351.33 kg ha-1), phosphorous (96.94 kg ha-1) and potassium (231.88 kg ha-1) content in soil were found significantly higher in T3 (INM1+ S3) over other treatments where as, T10 (INM4+ S1) recorded the lowest. The nutrient content in plant i.e. nitrogen (1.65%), phosphorous (0.93%), and potassium content (1.20%) in plant was found significantly maximum in T3 (INM1+ S3) while, the minimum was recorded in T7 (INM3+ S1). Regarding nutrient uptake by the crop, nitrogen (87.79 kg ha-1) phosphorous (61.10 kg ha-1) and potassium (61.99 kg ha-1) were found significantly higher in T1(INM1+ S1), while it was the lowest in T8 (INM3+ S2).
