The traditional agriculture predominate in the Sudan, most
technical packages and applications of modern agriculture
were not known to the farmers, which includes fertilization
and plant nutrition, Despite the success, which demonstrated
chemical fertilizers to gain increased productivity of many
crops, but heavy application of chemical fertilizers may
cause negative effects on the environment and the
accumulation of certain substances that pollute the soil and
discourage some minor elements to be not available to plant;
this make alternatives to chemical fertilizers Subject to
search and the path of discussion to avoid the negative
effects of chemical fertilizers. Among the means available to
achieve sustainability in agricultural production, organic
manure and bio-fertilizer which play an important and key
role because they possesses many desirable soil properties
and exerts beneficial effect on the soil physical, chemical and
biological Characteristics. However, the most optimum
organic and bio-fertilizer doses as well as their effectiveness
for upland crops have not been studied in details. In this
regard an attempt has been made to study the influence of
organic and bio-fertilizer in relation to chemical fertilizers on
rice production.
