Abstract

Trichoderma harzianum as well as Glomus mosseae inoculum (separately and combined) were prepared, and soybean plants were treated by these inocula in a greenhouse to compare their proximate analyses in sterilized and unsterilized soils. Soybean plants grown on sterilized soil gave higher percentage of crude fiber (3.66%), carbohydrate (50.00%), ash (4.53%) as well as dry matter (90.41%) than those grown on unsterilized soil. However, soybean grown on unsterilized soil gave higher percentage of crude protein (30.11%), oil (12.93%) and moisture content (9.62%) than those grown on sterilized soil. The inoculated treatment GT and G produced significantly higher (P < 0.05) amount of CP (30.22%) and (90.61%); and MC (9.86%) respectively than the control. Treatment of soil with combined T. harzianum and G. mosseae inoculum or separately in sterilized or unsterilized soil, will act as biofertilizer which can invariably improve yield, seed quality as well as the seed composition of soybean.

Key words: Moisture content, seed composition, seed quality.
