Productivity and nutritional composition of maize fodder grown by hydroponic and conventional methods

Abstract

To achieve the objectives of the study, different biopolymer along with natural dye (marigold petals). It was found that chitosan treated samples exhibited highest percent dye absorption (50.25%), colour strength (10.51) and wash fastness grades was found same (4) for all biopolymer treated dyed fabric. Among these biopolymers the chitosan showed the highest dye absorption, colour strength and wash fastness rating with natural dye. Thus we can efficiently use the chitosan as a mordant to replace the synthetic harmful mordant with biopolymer in environmental friendly manner, to reduce pollution load on environment and save resources.
