This study aimed to evaluate the characteristics of in vitro fermentative digestibility of odot grass planted at different spacing and defoliation ages-days after planting (DAP). The study was conducted in the Field Laboratory of the Faculty of Animal Science of the Halu Oleo University and the Laboratory of Nutrition for Dairy Sciences of the Faculty of Animal Husbandry, IPB University. The study was designed by using factorial randomized block design (3x3). The first factor was planting spacing (60 cm x 90 cm, 75 cm x 90 cm and 90 cm x 90 cm), and the second factor was defoliation age (60 DAP, 90 DAP, and 120 DAP), consisted of 4 groups and there were 36 treatment combinations. The grouping was based on the slope of the land. The study data were analyzed by using analysis of variance using SPSS 21 and if the treatment had a significant effect, a different test between treatments was tested by using the Duncan’s Multiple Range Test (DMRT) test. The experimental results showed that the interaction between planting spacing and defoliation age did not affect the characteristics of fermentation and nutrient digestibility in vitro. However, the in vitro fermentation characteristics were affected significantly (<em>p</em><0.05) by defoliation age, but were not affected by planting spacing whereas the pH level was not affected by spacing and defoliation age. Further tests of the differences between treatments showed that the planting spacing treatment was not significantly different (<em>p</em>>0.05), whereas among the defoliation age treatments were significantly different (<em>p</em><0.05). The conclusion of this study was the treatment of planting spacing and defoliation age did not affect digestibility in vitro fermentative of grass odot. The treatment of defoliation age independently influenced the in vitro digestibility of odot grass.

Randomized Block Design

The study aimed to evaluate the agronomic characteristics of elephant grass (Pennisetum purpureum Schum.) genotypes on energy production in the combustion form. A randomized block design with 3 repetitions was used. The treatments were arranged in subdivided plots scheme, considering as a plot the genotypes and as subplots, the harvest season. The agronomic characteristics plant height (H), leaf length (LL), leaf blade width (LBW), stem diameter (SD), tillers number (TN), stem percentage (SP), dry matter yield (DMY) were evaluated. The rainy season provided greater H to elephant grass genotypes with height above 3.5 m. The average SP obtained by the genotypes was 68.21% and 67.21% to the first and second year of cultivation, respectively, which gives the biomass good quality of burning. The rainy season provided greater DMY comparing to the dry season. In the first year of cultivation there were genotypes with annual dry matter yield (ADMY) above 50 ton ha-1 year-1, however, the non-maintenance of soil fertility promoted the reduction of 39.17% and 39.05% in the DMY and ADMY, respectively. Analyzing the agronomic characteristics, we conclude that the promising genotypes of elephant grass to produce energy in the form of direct combustion are CNPGL 91-25-1, Cubano Pinda, BRS Canará, Porto Rico and Mercker.

SUMMARYHerbage accumulation is determined by the tissue turnover of individual plants and by the regulation patterns of the number of individuals in a plant population, which function in conjunction to enable swards to adapt to variations in growth and management conditions. Based on the hypothesis that intermittent grazing strategies change the proportion of basal and aerial tillers and, consequently, sward herbage accumulation, the objective of the current experiment was to evaluate the components of herbage accumulation in elephant grass cvar Napier (Pennisetum purpureum Schum. cvar Napier) from January 2011 to April 2012. The treatments corresponded to combinations of two post-grazing (post-grazing heights of 35 and 45 cm) and two pre-grazing conditions (0·95 and maximum canopy light interception during regrowth – LI0·95 and LIMax) and were allocated to experimental units (850 m2 paddocks) according to a 2×2 factorial arrangement in a complete randomized block design with four replications. The following response variables were evaluated: the population density of basal tillers (TPDb) and the population density of aerial tillers (TPDa), the number of aerial tillers per supporting unit (A/B+VC), growth rates of the leaf (LGR) and stem (SGR), leaf senescence rate, net leaf accumulation rate (LAR), and the contributions of basal and aerial tillers to sward growth and senescence. The swards managed with the LI0·95 target had greater TPDb than those managed with the LIMax target, but no difference was recorded between the LI pre-grazing targets for TPDa. The larger A/B+VC ratio recorded for the swards managed with the LIMax target resulted in a higher contribution of aerial tillers to the growth and senescence of swards. This growth strategy resulted in a higher SGR and lower LGR and LAR for the swards managed with the LIMax target relative to those managed with the LI0·95 target. The post-grazing height targets affected only LGR during winter and the second summer and SGR on average for the experiment, with higher values recorded for the swards managed at 35 cm. The LI pre-grazing targets played a central role in defining the compensatory mechanisms responsible for the competitive ability of the plants, which were primarily expressed in the variation of the proportion of basal and aerial tillers in the tiller population and interfered with the components of herbage accumulation and total herbage yield of the swards.

Liquid organic fertilizer with the right concentration is expected to be a source of nutrients for the growth of mini elephant grass. The aims of this study were to determine the effect of liquid organic fertilizer with different concentrations of urine and Local Microorganism (LMO) on the production of mini elephant grass. The research method used was a randomized block design (RBD) with 4 treatments and each treatment consisted of 3 groups as replications. The treatments used were liquid organic fertilizer, with concentrations of P0 (as a control), P1 (100 % urine, 0 % LMO), P2 (90 % urine, 10 % LMO) and P3 (85 % urine, 15 % LMO). The results showed that liquid organic fertilizer with different concentrations of urine and MOL had no significant effect on plant height, number of leaves, number of tillers and production of fresh weight (g/clump). The liquid organic fertilizer with different urine and MOL concentrations has no significant effect on the growth and production of mini elephant grass.

Structural characteristics (total in marked tillers of leaves (NFT), expanded leaves (NCE), green leaves (NFV) and dead leaves (NFS) and number of tillers per plant (NPP)) and morphogenic variables (tillering (TApPP) and rates of total leaf (TApFT), expanded leaf (TApFE) and live leaf (TApFV) appearance) were evaluated in four elephantgrass genotypes (Napier, Cameroon and Pioneiro cultivars and clone CNPGL 91 F27 05). Greenhouse evaluations were carried out every three days, from the 3rd to the 60th day after standardization cutting, according to a completely randomized block design under a factorial treatment scheme (four genotypes and 21 measurement days). The NFT and NCE of the CNPGL 91 F27 05 and Pioneiro genotypes were larger than those of Cameroon and Napier genotypes. The average TApFT was 0.249 leaves/day. The NFS increased progressively and equaled the growth of NCE 44 days after the standardization cut. Number of leaves and number of tillers per plant were positively correlated. The highest values for NFV were about eight and nine. A great potential for leaf density was observed for the Pioneiro cultivar.

This study aimed to evaluate the chemical composition and fatty acid (FA) profile of chopped forage and silage of BRS Capiaçu elephant grass at four regrowth ages: 50, 70, 90 and 110 days. A randomized block design with five replications was used. The ensiling was carried out manually in experimental silos without wilting using no additives or bacterial inoculants. The results were analyzed using mixed models (P < 0.05). The model included treatment (regrowth age) as a fixed effect and block as a random effect. Linear and quadratic effects of the treatments were analyzed using orthogonal contrasts. There were linear increases in the dry matter (DM, g kg-1) and lignin (g kg-1 DM) contents and linear reductions in the in vitro DM digestibility (g kg-1) of chopped grass and silage as a function of regrowth age (P < 0.001). Quadratic effects (P ≤ 0.01) were observed for the chopped grass contents (g kg-1 DM) of crude protein (CP), ether extract (EE) and neutral detergent fiber (NDF) as a function of regrowth age. There were linear decreases (P < 0.0001) in the CP content (g kg-1 DM) and pH and linear increases (P < 0.001) in the EE and NDF contents (g kg-1 DM) in the silage as a function of regrowth age. There were linear decreases (P < 0.01) in the chopped grass contents and linear increases (P < 0.05) in the silage contents of total FAs, linoleic and α-linolenic acids (g kg-1 DM) asa function of regrowth age. BRS Capiaçu elephant grass must be harvested at up to 70 days of regrowth to obtain forage with good nutritional value and the highest levels of linoleic and α-linolenic acids (g kg-1 DM). To produce silages with adequate pH values and the highest levels of linoleic and α-linolenic acids (g kg-1 DM), BRS Capiaçu must be harvested between 90 and 110 days of regrowth.
