GROWTH RESPONSE OF Pennisetum purpureum, Setaria spacelata AND Panicum maximum IN SALINITY
Abstrak
The study was conducted to determine the response of the growth of 3 grasses species to salinity. The
study was conducted for 3 months, at Kompleks Perumahan Dosen UNIPA Amban in Manokwari West
Papua. The study was designed with a split plot design in to Completely Randomize design (CRD) 4x3
with 4 replications. As the main plot is grass species and the subplot is salinity based on growing media.
Main plot is grass species (Sp) consisting of: Pennisetum purpureum (Sp1), Panicum maximum (Sp2) and
Setaria spacelata (Sp3) and then subplot is growing media (M) consisting of: soil 100% (M0), soil 70%
+ 30% of sand (M1), soil 50% + 50% of sand (M2) and soil 30% + 70% of sand (M3). Statistical analysis
shows that the effect of salinity is significant on plant growth variable, namely plant height, number of
leaves and number of tiller in each grass species. Planting media M1(soil 70% + sand 30%) performs the
best result, and species with positive response to salinity is Setaria grass (Sp3).
