Growth and Yield of Amaranthus (Amaranthus spp.) Varieties in Different Planting Systems under Shade Nets during the Kharif Season

Abstract

The present investigation carried out at College of Horticulture, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth Dapoli, Dist. Ratnagiri during kharif season in year 2023-2024. The experiment was laid out in Factorial Randomized Block Design consist of eight treatments with four replications. In the experiment Factor: A composed four amaranthus types V1: Konkan Durangi, V2: DPL-AS-6, V3: DPL-AS-4, V4: Nigadi Local and Factor: B is planting systems B1: Flat bed, B2: Raised bed. During investigation, the analysis of variance revealed that all the characters viz. growth parameters and yield attributing characters varied significantly. In amaranthus types Konkan Durangi (V1), recorded minimum days required for germination (3.12), highest plant height (25.72 cm), stem diameter (4.98 mm), number of leaves per plant (8.72), minimum days to first harvest (24.83), maximum number of harvests (3.30), highest mean yield per square meter (1.39 kg) and yield (13.92 t ha-1). In the planting systems raised bed (B2), had the minimum days required for germination (3.41), highest plant heights (25.27 cm), number of leaves per plant (8.45), longest leaf length (7.06 cm) and widest leaf breadth (3.99 cm), largest stem diameter (4.17 mm), minimum days to first harvest (25.60), maximum number of harvests (3.01), mean yield per square meter (1.31 kg) and yield (13.06 t ha-1).
