Abstract

THE EFFECT OF CUTTING AGES AND LEVEL OF ORGANIC FERTILIZER ON VEGETATIVE GROWTH OF BRACHIARIA HUMIDICOLA (Case Study At Agrostology Laboratory Faculty Of Animal ScienceSam Ratulangi UniversityManado)Brachiaria humidicola is a forages as animal feed. Defolation is a proces which is apart of vegetative removed by human or by grazing animals. Brahum is one of perenial species has stolon and has a good  ground cover. From agrostology point of view Brahum needs a good agronomic management and it is not as weeds species.     The aim of this experiment to asses the effect of defolition and level of organic fertilizer on vegetative growth of Brahum Treatments consist of ages of cutting of 30 day and 40 day after triming, and level of organic fertilizer of P1=0 gr; P2=400 gr; P3=800 gr; P4=1200 gr/polybag. Variable measured was the number of stolon, long of stolon and number of tiller. Treatment was arranged factorial 2x4 based on completly randomized design (RAL) with 4 replication.     The results of this research show that the interaction of treatments significandtly effected on all variabel measured, and the best result found at interaction between cutting ages 40 day and level of organic fertilizer 400 gr/polybag. Based on this result it could be concluded that do get the best performance of Brahum need to cut at 40 days regrowth and dosis of organic fertilizer by 400 gr/polybag. Keywords : Age of cutting, organic fertilizer, Vegetative growth, Brahum

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
