Abstract:
In order to investigate the effect of spacing and pinching on growth, flowering and yield of french marigod an experiment was carried out during rabi season 2022-23 at Hazipur research farm, C B G Agriculture P G college, Lucknow (U.P.). The experiment was on Tagetes patula, the French marigold flower in combination of two intervals of pinching at 30 DAT and 60 DAT with three spacing viz., 30X30 cm, 30X45 cm and 30X60 cm respectively. Making it all in nine combinations which were tested in factorial randomized block design. Maximum plant height was recorded with closer spacing S₀ i.e.30 x 30 cm (58.90 cm) followed by closer spacing S₁ i.e. 30X45 cm (57.88 cm) respectively. Under pinching treatment maximum height was recorded with P₁ i.e. without pinching (57.91 cm) followed by (55.62 cm) with P₁ i.e. pinching (at 30DAT) respectively. While growth characters under spacing treatment i.e. maximum spread of plant (35 cm), Numbers of branches (38.60) and Diameter of stem (1.65 cm) were recorded with wider spacing S2(30x60 cm) followed by S₁ (30x45 cm). However, maximum spread of plant (31.40 cm), Number of branches per plant (37.5 cm) and diameter (1.63 cm) were recorded with pinching after 60 DAT respectively. spacing and pinching affects yield characters of Tagetes patula mainly Dry matter content (18.56%) (19.38%), Number of flower (48.31) (51.97), Fresh weight of flower (445.6 g) (452.5 g), yield of flower (306.2 q/ha) (321.3 q/ha), Net return (126696.7 rs/ha) (129698.7 rs/ha) and B:C Ratio (1.42) (1.44) were found with the widest spacing (30X60 cm) and pinching done at 60 days after transplanting. Results revealed that plants pinched at 60 DAT with widest spacing (30X60 cm) were giving best growth and flowering of French marigold respectively.
