Abstract:
The present investigation entitled “Studies on effect of nano urea on growth on French basil (Ocimum basilicum L.) cultivars under Southern Telangana conditions” was carried out during rabi season of the year 2021-22 at college of Horticulture, Rajendranagar. In an attempt to achieve the objective of effect of nano urea on growth on French basil (Ocimum basilicum L.). The field experiment was laid out in factorial randomized block design with 3 replications and eight treatment combinations. The different varieties (2 varieties) are V1 (CIM-Saumya), V2 (CIM-Sharada) and fertilizers (4 levels) F₁ - 75% RDN + Nano Urea @ 2 ml/l (2 sprays at 30, 60 DAT), F₂ - 50% RDN + Nano Urea @ 2 ml/l (2 sprays at 30, 60 DAT), F₃ - 25% RDN + Nano Urea @ 2 ml/l (2 sprays at 30, 60 DAT) and F₄ - 100% RDF (Control). Between varieties, at 45, 60 and 75 DAP (Days after planting), highest plant height (43.64 cm, 54.65 cm, 68.58 cm), highest number of branches per plant (12.72, 17.40, 22.65), highest number of leaves per plant (555.3, 655.3, 755.5), highest plant spread N-S (47.90 cm, 51.04 cm, 54.80 cm) and E-W (45.69 cm, 48.88 cm, 52.92 cm) was observed in variety V1 (CIM-Saumya).
