Performance of Red Amaranth under Shade Condition for Agroforestry Systems

ABSTRACT

Performance of red amaranth (Amaranthus gangeticus) under four levels of light- 100, 75, 50, and 25% photosynthetically active radiation (PAR) was evaluated to judge its suitability for inclusion in agroforestry systems. Mosquito nets of different mesh size have been used to create desirable light levels. It was observed that in red amaranth, any reduction in PAR affected all morphological and yield parameters of red amaranth negatively. Plant height, number of leaves plant-1, leaf size, stem girth, fresh and dry yield were decreased significantly with decreasing light levels but the trend of response of different morphological parameters to different light levels were different. The mean fresh and dry yield (t ha-1) of red amaranth grown under 100, 75, 50 and 25 % PAR levels were 12.77, 9.54, 5.75, 3.19 and 1.27, 0.92, 0.55, 0.26, respectively. Therefore, red amaranth may not be included in tree-crop agroforestry system.
