Abstract

Salty soils are recognized as an ever increasing problem connected with irrigation agriculture. Millions have been spent by state, federal and private agencies on technical research in an attempt to solve this problem. Other millions have been spent on drainage projects, land leveling, field explorations and soil amendments attempting to alleviate the situation in the field. Physical conditions such as lack of drainage outlets or the impermeable nature of soils may prevent reclamation. Some areas are physically capable of drainage but the cost would be excessive. This condition necessitates the production of salt tolerant and sometimes water tolerant crops if such lands are to give any returns. Other lands may produce such crops during the reclamation period. Plants are known to vary in their ability to grow under salty conditions; however, salt tolerance does not insure profitable production. Some highly tolerant plants have little economic value and/or their production on salty soil may be very low. Some plants are known to be salt tolerant in the mature stage but sensitive in the seedling stage. This study concerns the emergence and survival of certain forage plants when seeded in a saline soil. The techniques used in approaching this problem have been modified since this study was conducted.
