Abstract :
The effect of three Glomus species on growth
parameters in term of shoot length, root lenght, dry weight
proximate composition and quantitative evaluation of
mycorrhizal dependency of three sorghum (Sorghum bicolor
L.) varieties i.e. SS-1 Johar, PARC SS-2 and SP-462 were
evaluated. The AM inoculated plants showed significantly
better performance than the non-inoculated plants in terms
of plant height, number & length of leaves, root length,
number of seminal roots and dry weight. Proximate analysis
showed enhancement in crude protein, fat, moisture and ash
content in mycorrhizal plants except carbohydrate and crude
fibers. Regarding mycorrhizal dependency (M.D), maximum
value was noted in SV2 (74.30%) variety while least was
observed in SV3 (21.30%). This study clearly indicates the
potential of using indigenous AM fungi (Glomus species) as
biofertilizer in sorghum crop in low fertility soils hence
reduce chemical fertilizer input and proved to be
environment friendly.
