Abstract

Utilization of forages grown underneath the plantation crops is widely practices in the region of Southeast Asia and in the Pacific island. Since the plantation crops do not fully utilize all incoming radiation and nutrients, their competition with natural vegetation for nutrients is inevitable. In coconut plantation native forages and natural vegetation cannot survive under heavy grazing due to lack of grazing management practiced by farmers. This will lead to overgrazing and compacting the soil and in some circumstances triggering erosion, changing in botanical composition due to invasive weeds, and disappearance of the planting forages species. This disappearance is also probably due to other factors such as intolerance of those species in the shaded environment. However, this is not the case. Although shade tolerance species are planted, the pasture run-down still occurs. To overcome this problem there are three new approaches. The first one is that defoliation should based on biogeochemical process consideration.  It is should pay attention on the rhizosphere environment to ensure the nutrients uptake by forage, especially grasses is fulfilled.  The second one is that defoliation should ensure the health of the grass subject to cutting. With the climate change phenomenon, where the air CO2 is abundance, following by the increasing of air temperature, the time of defoliation or grazing should be focused on counting the accumulation of heat unit rather than focusing on forage’s age. The third one is that the appropriate grazing systems and stocking rate should take into account, to ensure the plant to have ability to recover after grazing.

Abstract

GROWTH RESPONSE OF Brachiaria humidicola cv Tully grass WITH ORGANIC FERTILIZER BOKASHI LAYING CHICKEN. This study aims to determine the growth response i.e stolon length, number of nodes, number of phytomers, and number of tillers of Brachiaria humidicola cv Tully with bokashi organic laying hens fertilizer. The completely randomized design was applied using four treatments and five replications for each treatment. The treatments were assigned level of bokashi. The levels of bokashi that B0 = 0 tons/ha (control), B1 = 2 tons/ha (1.8 kg/plot), B2 = 4 tons/ha (3.6 kg/plot) and B3 = 6 tons/ha (5.4 kg/plot). The variables measured consisted of stolon length, number of nodes, number of phyitomers, number of tillers. The Results of analysis of variance showed that treatment very significantly different (P <0.01) on stolon length, number of phyitomers, number of tillers and significantly different (P <0.05) on the number of nodes. Test of Honest Significance Difference (HSD) showed that B1 (1.8 kg / plot), B2 (3.6 kg / plot), and B3 (5.4 kg / plot) have higher length of stolone, number of phyitomers and number of tillers than B0. B3 and B2 had higher numbers of nodes than B0. It was concluded that the level 1.8 kg/plot organic fertilizer bokashi chicken laying equivalent to 2 tons/ha gave highest B. humidicola cv Tully growth response. Keywords: growth, B. humidicola cv Tully, bokashi laying Chicken

Abstract

EFFECT OF HIGH AND DISTANCE OF CUTTING TIME OF DWARF ELEPHANT GRASS (pannisetum purpureum cv. Mott) ON VEGETATIVE GROWTH AND DRY MATERIAL PRODUCTION. This research aims to identify and obtain data about the effect of height and distance of cutting time on vegetative growth and dry material production of dwarf elephant grass (pannisetum purpureum cv. Mott). The treatments were applied into factorial design on the base of Group Random Design (GRD) which consists of two factors and three replications. Factor A were cutting height, a1 = 0 cm above the ground, a2= 5 cm above the ground, a3= 10 cm above the ground, a4= 15 cm above the ground. Factor B age of cutting, b1 = 20 days, and b2 = 30 days. The measured variables were including the number of tillers, ratio of leaf/stem and dry material production. Result of analysis of variance (ANOVA) showed that the number of tillers and dry ingredient of grass were affected very significantly (P < 0,01) by the interaction of high of cutting and the age of plant. However, the age of plant was giving a significantly different effect (P < 0,05) on the leaf/steam ratio. While the interaction high of cutting and age of plant did not significantly affect (P > 0,05) the leaf/steam ratio. Based on the research, it can be concluded that I order to ensure the continued production of P.purpureum cv.Mott measured in the number of tillers and dry ingredient, it should be cut at the age of 20 and 30 days with a cutting height of 15 cm above ground level. The highest value of leaf/steam ratio was obtained at the cutting age of 20 days.Keywords : P. purpureum cv. Mott, high and age of cutting, growth, dry material production
