Fat Analysis The analyses of forage quality

25 effects of light quality on whole plant mineral nutrient uptake and status have been little studied Aphlaho 2006. In actual condition forage plantation was forced by the limitation of sun availability that could be influence forage production. This condition occurred as the impact of competition both the trees and its plant. In general, plants have two main strategies in response to light competition: overgrow and shade the competitors andor tolerate shade by maximizing growth under reduced light Humphreys 1981. The former was obviously not a viable strategy for pasture plants growing in association with trees. However, tropical grasses were differing in their tolerance of shade. Several data were gained as its responses regarding to different levels of solar radiance, the utilization of organic fertilizer and defoliation management. The information consists of variations including forage yield, plant architecture plant layer height, and leaf area also chlorophyll concentration. In the early respond was provided the measurement on forage yield production on P. purpureum. Table 7. The Measurement forage yield Mgha P. Purpurem on different levels of shade, organic fertilizer and defoliation management treatments.

The data illustrated that levels of shade, organic fertilizer and defoliation management were persuaded on forage yield on P. purpureum. The study showed that yield production depressed as the less number of irradiance accepted by plants. At the same time, the utilization of higher amount of organic fertilizer enlarged yield production compared with less organic fertilizer. It was observed underneath shading condition, the forage yield was reducing, but it could be enhance by adding the organic fertilizer. Underneath shading condition 26 5 10 15 20 25 30 35 60 80 M g ha a a b 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.
