Comparative performance of Amaranthus (Amaranthus spp.) genotypes in different growing media under shade net condition

Abstract

The current investigation entitled effect of organic manures under shade net condition in raised bed system on growth attributes of Amaranthus (Amaranthus spp.), was conducted at Dr. B. S. K. K. V., Dapoli during the kharif season in the year 2024. In the experiment, there were twelve treatments and three replications in Factorial Randomized Block Design (FRBD), comprising factor A: Amaranthus genotypes (3) and factor B: Growing media (4). The experimental results depicted that the treatment combination T7 [Nigdi grown in with Soil + Vermicompost (10 t ha-1)] revealed significant superiority over other treatments in respect to the growth parameters and yield attributes viz., days required for germination, plant height, number of leaves, leaf length, yield per meter square, yield per hectare. However, the treatment combination of T5 [Nigdi local grown in soil + FYM 10 t ha-1)] noted significantly at par results, in kharif seasons. Vermicompost improved soil conditions through better nutrient availability, drainage, temperature and aeration, accelerating growth and advancing harvests in Amaranthus. However, final performance was chiefly governed by the inherent genetic traits of each genotype.
