Purpose: As a result of adverse climatic conditions and inadequate soil management practices an experiment was carried out to study the effect of compost on reducing irrigation water use to product maximum yield of sorghum bicolor in a sandy soil.
Design/methodology/approach: A pot experiment was conducted under natural conditions, the pots were arranged in a complete randomized block design. The main plots were assigned to water treatment, the sub plots to the compost management and Least Significant Differences (LSD) test was used to determine differences among means (LSD at P<0.05).
Findings: The study proved that reducing irrigation water to 50% while increasing quantity of compost to 10 t ha-1 produced higher plant height.
Originality/value: The addition of compost to the soil is valuable to economize irrigation water use in a harsh land like a sandy soil.
