| Abstract |
In a calcareous sandy loam soil under Zea maize plants, a field study was conducted to monitor three summer seasons (1997, 1998 and 1999) for evaluating sub-surface drain spacings (25, 40, 70, 90 and 150 m with 1.5 m average drain depth). The obtained data reveal that the sub-surface drainage system is appreciable lowering water table, reduction in salts and increase crop yield of Zea maize. The deep water table, decrease in profile salinity and increase in crop yield in the drain spacing of 25 m and 40 m. These two drain spacings (25 and 40 m) are highly effect on water table, soil profile salinity and maize yield as compared with those of others (70, 90, 150 m drain spacings and un-drained). A highly significant decrease in soil salinity is found due to leaching and continuous cropping. However, the increase in crop production of maize has no significant difference between 25 and 40 m drain spacings, but there is a highly significant difference between 25, 40 m and those of 70, 90, 150m drain spacings. A highly negative significant correlation is found between grain yield of maize and both of soil salinity, sodium and chloride ions and SAR values. Therefore, installing sub-surface drainage system, net profit of crop production depend on drain spacings and capital investment under the studied soils.
Key words: Sub-surface drainage, drain spacings, water table, soil salinity, calcareous soil, zea maize production.
