The experiment was conducted at the Institute of Agriculture, Agricultural Engineering College and Research Institute, Tamil Nadu Agricultural University, Kumulur, Tamilnadu, India. The experiment was conducted in Completely Randomised Block Design with 3 treatments and 8 replications during rainy and summer seasons. Three different growing conditions such as Polyhouse (T1), Shadenet (T2) and open condition (T3) were fixed as three treatments. The variety used in the study was Amaranthus PLR 1. Parameters such as Plant height (cm), Leaf Weight (g), Stem weight (g), Root weight (g), Total plant weight (g), Total green weight (g), Plot yield (kg) and Total yield (t/ha.) are recorded after harvest at 21st day after sowing. In rainy season, maximum plant height (25.68 cm) at 21 DAP was recorded under shade net condition, followed by polyhouse condition (23.57 cm). Amaranthus grown under Polyhouse condition recorded significantly the highest in leaf weight (1.23 g), stem weight (2.17 cm), root weight (0.53 cm), total weight (3.93 cm), plot yield (19.67 kg) and yield (8.50 t/ha). It was followed by amaranthus grown under shadenet condition. In summer season, amaranthus grown under shade net recorded maximum values in all the observed parameter such as plant height (24.47 cm), leaf weight (1.53 g), stem weight (2.36 g), root weight (4.62 g), total weight (4.62 g), total green weight (3.89 g), plot yield (19.32 kg) and total yield (9.60 t/ha). It was followed by amaranthus grown under polyhouse condition. From these experimental findings, we conclude that the yield performances of Amaranthus PLR 1 are better under polyhouse during rainy season and under shadenet during summer conditions. The variation in the performance of Amaranthus under polyhouse and shadenet based on the season is proportional to the availability of optimum temperature and relative humidity for the crop in that seasonal condition.
