Abstract:
The experiment entitled “Study on effect of different levels of nitrogen in combination with nano urea on growth and yield of marigold (Tagetes erecta L.) Cv. Pusa Narangi Gainda” was conducted during the Rabi season of the year 2021-2022 at College of Horticulture, Rajendranagar, Sri Konda Laxman Telangana State Horticultural University. Among the treatments, the treatment T₄ (50% N + Nano Urea @ 2 ml/l (2 sprays at 25 DAT and 50 DAT) recorded maximum plant height (71.33 cm), plant spread in North- South direction (49.67 cm), plant spread in East-West direction (50.67 cm), number of branches plant^-1 (9.26), leaf area (14.80 cm²), individual flower weight (9.17 g), flower diameter (5.69 cm), number of flowers plant^-1 (29.01), flower yield plant-1 (220 g), flower yield plot^-1 (4.42 kg) flower yield hectare^-1 (11.05 t), whereas minimum number of days taken to first flower bud initiation (32.8 days), number of days taken to 50 percent flowering (46.73 days), number of days taken to full bloom (49.73 days) and maximum duration of flowering (45.74 days) was recorded by T₁ treatment (100% RDF). However, T₆ (Nano Urea @ 2 ml/l (3 sprays at 25 DAT, 50 DAT, 75 DAT) recorded minimum in all the parameters.
