EFFECT OF BULKY AND CONCENTRATED ORGANIC AND BIO-MULCHES ON PHYSICO CHEMICAL PROPERTIES OF SOIL IN BABY CORN FIELD

Abstract

The experiment was conducted to Influence of organic and bio-mulches on physico-
chemical properties of soil in baby corn cultivation field at Annamalai Nagar. The experiment
was laid out in a randomized block design with eight treatments in three replications.
According to the treatment schedule, mulching was practiced after 15 days of crop
germination. The mulch materials used were sugarcane trash at 10 cm thickness (12 t ha-1),
coir pith at 2 cm thickness (10 t ha-1). Sawdust 2 cm thickness (10 t ha'1) and crop residues at
10 cm thickness (10 t ha-1). For the bio-mulches, seeds of fenugreek and coriander were
sown and cuttings of mint were planted 20 DAS of main crop. Among the organic and bio
mulches were identified. The mulch materials used was sugarcane trash at 10 cm thickness
(12 t ha-1) which recorded the maximum level of water holding capacity of soil, ph and
organic carbon of baby corn field .
