Abstract:
The objective of this study was to establish the best planting spacing and nitrate, phosphorus, and potassium concentrations for the growth of French marigolds in the Rabi season of 2022–2023. With 15 treatment combinations, a Randomized Block Design (RBD, Factorial) was used. These combinations included three planting spacings (S₁: 30 x 30 cm, S₂: 40 x 30 cm, and S₃: 40 x 40 cm) and five NPK application dosages (F₁: 70:30:10 kg ha^-1, F₂: 85:45:25 kg ha^-1, F3: 115:75:55 kg ha^-1, F₄: 130:90:70 kg ha^-1, and F5: 100:60:40 kg ha^-1). In accordance with the findings, the treatment combination F₄S₃ substantially had the maximum number of primary branches (29.57), secondary branches (45.22), flowers (110.33), and flower yield per plant (0.276 kg). Which was at par with treatment combination F₄S₂ for the number of primary branches, number of flowers and flower yield per plant.
