Profile Modification of a Slowly Permeable Soil1

Abstract

Abstract

Under limited water (preplant irrigation only), profile modification of Pullman silty clay loam to depths of 90 and 150 cm increased grain sorghum (Sorghum vulgare, Pers.) yields by 66.2 and 80.1%, respectively, over a 3-year period. Modification (both 90 and 150 cm) increased water use efficiency in grain and total dry matter production by 41.3 and 25.2%, respectively. The increased yields and water use efficiencies resulted from changes in amount and distribution of stored water in the profile and from changes in plant rooting patterns.

Under adequate irrigation, profile modification had little effect on grain or stover yields but increased water use efficiency in two of three seasons.
