Evaluation of fly ash as a constituent of pot mixture

Abstract

Fly ash mixed with farmyard manure, vermicompost, sand and red soil in different ratios on a w/w basis was used for growing tomato, chilli, marigold, celosia and papaya. The response of pot mixture on germination, growth and development of these crops. The results indicated that the fly ash based pot mix showed positive influence in enhancing different growth parameters. In generalthe treatment T11 1:3 fly ash: vermicompost and treatment T6 fly ash: farmyard manure in 1:3 ratio recorded the highest germination percentage, maximum plant height and vigour index. Fly ash based organic substrate pot mixtures benefits increase in plant growth which in turn attains significance from the point of view of production of cost efficient pot mix.
