Salt Salinity Tolerance on Nursery of Indigofera zollingeriana

Abstract

Indigofera zollingeriana., is a legume plant that has a high protein content and is very potential to develop as one of the forage crops. This study was conducted to determine the tolerance level of Indigofera zollingeriana, concerning to the level of NaCl concentration in cultivation seedlings as an effort to develop these forages on a marginal land, especially on saline land, so that the potential of saline land can be utilized properly. This study used a randomized block design with 3 groups and 5 replications, maintained and observed intensively for 30 days. The first treatment (P1) was grown on soil and compost media (1:1) and given a water without NaCl concentration. The second treatment (P2) was grown on soil, sand and compost media (1:1:1) and given a water with a concentration NaCl of 50 mM/2.925 g/l, and the third treatment (P3) was grown on soil, sand and compost media (1:1:1) and given a water with a concentration NaCl 100 mM/5.85 g/l. The results showed that Indigofera zollingeriana growth and develop on medium on the salinity of 9.9 indicated that the plant's tolerance high salinity levels despite the effect of salt stress affecting growth plant.
