Key Points

Transplanting in the second week of February enhances growth and yield in African marigold.
The spacing of 60 × 30 cm significantly improves growth compared to other spacings.
Maximum flower yield per plant occurs with the interaction T1S1, while highest yield per hectare is with T1S3.
The study utilized a randomized block design with factorial treatment combinations over two years.

Abstract

Flowering behavior of floriculture crops influenced by many agro-techniques. Among them, proper time of transplanting and spacing directly affect the growth and yield. The current study used an RBD (factorial) design with two factors: Factor 1: Transplanting time (T), which is the second week of February (T1) and the fourth week of February (T2); Factor 2: Spacing (S), which is S1: 60 × 30, S2: 45 × 30 and S3: 30 × 30 cm. The purpose of this study was to assess the impact of transplanting time and spacing on the growth and yield of summer African marigold (Tagetes erecta L.) cv. Punjab Gainda 1. Treatments were repeated thrice. Experiment was conducted for two years i. e. 2020-21 & 2021-22. Result showed that 2nd week of February (T1) influenced growth and yield. Among different spacing, 60 × 30 cm (S1) improved growth and yield. However, 30 × 30 cm (S3) gave higher yield per hectare. Interaction effect of T1S1 recorded maximum number of flowers and flower yield per plant, whereas flower yield per hectare was observed with T1S3.
