tailieunhanh - Quality blooming of marigold in hydroponics

An experiment to investigate “Quality flower production of Marigold in hydroponics” was conducted at Assam Agricultural University, Department of Horticulture. The experiment was laid out completely randomized design with two factor and three replications. In the experiment marigold plants were grown in five different hydroponic systems (NFT, Water Culture, Aggregate systems with Sand, Cocopeat and Sawdust as potting media) with three different level of hydroponic nutrient solution (EC dS/m, EC, dS/m and EC dS/m). Experimental results showed that the system, nutrient solution and their interaction significantly affected the flower quality and production. Among the systems, NFT was found significantly superior to all other systems in terms of quality flower production. Among the nutrients, early emergence of bud and flower was noticed in EC dS/m, whereas other flower characters were found to be significantly better in EC dS/m. Thus, from the floriculture perspective conclusion can be drawn that treatment combination of NFT and EC dS/m is optimum for quality flower production of marigold. | Quality blooming of marigold in hydroponics
