such as 60 and 80, the forage yield required higher organic fertilizer. In 40 and 50 days of plantation, the additional 30 Mgha organic fertilizer presences the
highest forage yield underneath limitation of sun availability. While, in the longer time or harvest time, it required less organic fertilizer to obtain maximum yield. In
60 days after plantation, the organic fertilizer was required for 20 Mgha. We calculated that as 31.1 of forage production was depleting, since it planted on
80 Levels of shade Figure 9.
Figure 9. The main effect levels of shade on forage yield P. purpureum. Subscripts with the same letter showed the significant different test by
Least Square Determination LSD in P0.05.
Moreover, the Analysis of Variance ANOVA result showed there was significance different on the Levels of shade P0.05. From figure 9, it could be
seen that forage yield showed significant differences on levels of shade. The result indicated that the less number of forage yield was produced in higher levels of
shade. It gained that the highest amount was obtained on 0 levels of shade as 30.50 Mgha. Furthermore, we also obtained the interaction both the organic
fertilizer and defoliation management due to forage yield Figure 10.

Figure 10. The interaction both fertilization and defoliation management on forage yield P.purpureum.
In figure 10, the interaction occurred as the impact of additional organic fertilization and defoliation management on forage yield. Furthermore, it could be
understood that the additional fertilizer, compacted with defoliation management. As in the early growing stage on the plant that required additional fertilizer to
support plant growth. In the longer time of defoliation management, the amount of fertilizer needed slowly decreasing. We also observed the influenced of
treatments on S. splendida. In table 8 was showing the forage yield S. splendida influenced by levels of shade, organic fertilizer and defoliation management.

Table 8 described the forage yield measurement of S. splendida. It could be seen from table 8 that the average of highest forage yield production was 24.73

shading highly influenced to forage yield. In S. splendida, within the longer time of defoliation management, it required less organic fertilizer. It could be seen in
Table 8 that the optimum forage yield for 0 levels of shade in 40 days after plantation for 30 Mgha, and with the longer time of defoliation management 50
and 60 days after plantation, the requirement of organic fertilizer was reducing for 20 Mgha. The result quite different with the influence of the limitation of sun
availability, whereas in 60 levels of shade showed the higher organic fertilizer requirement for 20 Mgha for 40 and 50 days after plantation. The organic
fertilizer was required higher for 30 Mgha for the longer time defoliation management 60 days after plantation. In this study, defoliation management has
a significance effect due to forage yield Figure 11.

different test by Least Square Determination LSD in P0.05.
Figure 11 described the influence of defoliation management due to fresh weight of S. splendida. It could be seen that the different time of days after
plantation has lead the different amount of fresh weight production. In this study, there was significance different on 60 days defoliation management p0.05. It
also found that S. splendida did not show the direct effect regarding to shading effect. However, the influenced of levels of shade has seen as the interaction with
the additional organic fertilizer Figure 12. a
