Standardization of different planting season and spacing on vegetative growth, flower yield and yield attributing character of African marigold (Tagetes erecta L.) variety Pusa Narangi Gainda

Abstract

The present investigation was conducted during Kharif, Rabi and Summer season 2019-20 and 2020-21 at College of Agriculture and Research Station, Raigarh, Chhattisgarh. The treatment comprised of three factors i.e. different planting season (Se1: Kharif, Se2: Rabi and Se3: Summer) three spacing (S1: 30 x 30 cm, S2: 45 x 45 cm, and S3: 50 x 50 cm). Three factor experiments are laid out in randomized block Design (Factorial) with three replication. The results revealed that (Se1) Kharif season produced significantly higher value of plant height, diameter of flower and yield attributes, (number of flower per plant, flower yield per plant (g), flower yield (kg) and yield (t/ha)) followed by (Se2) Rabi season during both the years 2019-20 and 2020-21 and mean of two years. While, (Se2) Rabi season recorded higher plant spread, primary and secondary branches, first bud appearance, fresh weight of individual flower, and 50% flowering under this investigation. The maximum significant plant height and earliest first bud appearance, flower yield per plant (g), flower yield (kg) and yield (t/ha) was obtaining in treatment (S1) 30 x 30 cm during both the years 2019-20 and 2020-21 and mean of two years. Maximum plant spread (E-W and N-S) in observed in treatment (S3) 50 x 50 cm during both the years and on the basis of mean data followed by (S2) 45 x 45 cm during this investigation.
