Abstract

Two field experiments were carried out during two seasons of 2004-2005 to
study the effect of inoculation with biofertilizers combined with different types of
composts on the growth vigour and productivity of maize plants (Zea mays) grown in
sandy soil. Some chemical and biological properties of the used soil after maize
cultivated were concerned.
Results of two seasons showed that inoculation with Serratia sp < /em>., Trichoderma
sp < /em>. or their mixture exhibited the higher values of dry weight of shoot and roots as well
as grain and stalk yields. Grains percentage of the mean of the two seasons
increases over uninoculated plants were 17.1, 11.2 and 24.5%, respectively. There
are significant increases in plant height, shoot dry weight due to bio-compost or town
refuse application compared to unamended soil. The increases in shoot dry weight
were 47.1 and 16.1 % for biocompost and town refuses application, respectively
against the unmanured soil. The increasing in grain yield over the mean of the two
seasons were 28.9 and 17.7% at the same order. Data general!y showed a slight
effect of inoculation on pH, EC, organic matter and total nitrogen content of soil under
investigation. On the other hand, application of organic materials displayed great
effect on all investigated soil properties. Using of 5 ton compost followed by using of 5
ton town refuse, strongly affect soil properties. The season of 2005 recorded the
higher values of the parameters than season 2004.
