Abstract

A seventy days pot experiment was conducted in season of 2002 to study
the effect of farmyard manure (FYM) and chicken manure (CM) individually and lor
together combined with or without a biofertilizer (SF) of Azospirillum brasilense and
Bacillus megaterium var. p < /em>hosphaticum on wheat growth grown on sandy, calcareous
and clayey soils. Results revealed that all manure treatments whether combined with
biofertilizers or not led to significant increase in wheat dry weights. Weights of plants
grown on clayey soil were higher than the corresponding grown in sandy or
calcareous soils. Response of wheat to organic manure treatments was more
pronounced in sandy and calcareous soils than in the clayey one. Although N, P and
K contents of wheat plants were higher in the clayey soil. yet the response to organic
manuring was more obvious in sandy and calcareous soils. Organic manures
application enhanced the biological activity in the remained soil in terms of
dehydrogenase activity, C02 evolution and total bacterial count.
