“…leaf width. The results of this study are lower than those reported [10,12] The responses of several parameters due to the treatment of harvest time and the administration of urea fertilizer on sorghum samurai I and the 2nd cutting (ratoon 1) can be seen in Table 2. All agronomic parameters produced in samurai sorghum I at the 2nd cutting (ratoon 1) showed no interaction (p >0.05) due to different harvest times and urea fertilizer application.…”

Sorghum is a forage plant that can improve the ability to high temperatures, dry resistance, and the ability of ratoons. Ratoon is the ability of sorghum to regrowth due to being cut several times at different periods. This study aimed to evaluate the agronomic characteristics of samurai I sorghum harvested in each harvest period until the 1st ratoon. The research method used in each harvest period was utterly randomized with a factorial design (3 x 3) with 4 replications. Factor A is the age of harvest consisting of 80, 85 and 90 days of treatment and Factor B is the dose of fertilization consisting of 200, 300 and 400 kg/ha. The research area is 3 x 3 m2 in each experimental plot. The results showed that up to the 1st ratoon, samurai sorghum produced better plant height, leaf width and length than the primary and first ratoon cuttings, although there was a decrease in stem diameter in the first ratoon. The conclusion is that samurai I have good stability of agronomic characteristics up to the first ratoon so that it has the potential to be harvested in the next ratoon.

“…Plant height due to harvest time and dose Different fertilizer applications resulted in the same value (p >0.05), meaning that the treatment used did not affect plant height parameters. Results The plant heights obtained ranged from 217.00 -243.80 cm higher than reported [10,11] that 164, 86 -184, 18 cm and 214.38 cm in sorghum brown midrib.…”

“…BMR mutations are phenotypically portrayed by the presence of brown vascular tissues in the leaf edge and sheath as well as in the stem (Rao et al, 2012). BMR sorghum results from a genetic mutation that contains fewer lignin compounds (Green et al, 2014;Sriagtula et al, 2021) and is a promising forage source because of these low-lignin characteristics (Sriagtula et al, 2019). The BMR type contains less cell wall content than standard forage sorghum (Astigarraga et al, 2014).…”

The objective of this study was to evaluate the yield, nutrient profile and in vitro digestibility of new BMR mutant lines of sorghum in Indonesia. These mutant lines were GH2.1, GH2.2, GH2.3, GH4.1, GH4.2, GH4.3 and GH4.4. One sorghum mutant line (CTY) and two national sorghum varieties (Super 1 and Bioguma) were also evaluated as controls. In vitro digestibility and rumen fermentation were measured using Ankom Daisy Fermenter and Hohenheim gas test methods, respectively. In vitro measurement consisted of ten treatments with five replications following a completely randomized design. The highest stem sugar content was found in Bioguma (11.22%) and GH4.4 (9.32%) (p<0.05). The Bioguma variety and the GH2.3 mutant line had a higher number of stem segments and fresh forage yield than the Super 1 variety (p<0.05). A greater concentration of crude protein (CP) was observed for the GH.2.1, GH2.2, GH2.3 and GH4.1 lines (p<0.05). The GH2.3 mutant line had the lowest acid detergent lignin (ADL) content (p<0.05), while Bioguma had the highest level of non-fibre carbohydrate (NFC) compounds (p<0.05). The highest relative feed value (RFV) was observed for the GH2.3 line (p<0.05). Furthermore, GH4.2 and GH2.3 had greater in vitro true digestibility (IVTD) (p<0.05) but were not significantly different from Bioguma. Regarding yield characteristics, nutrient composition and in vitro digestibility values, the highest values were found in the Bioguma variety and the GH2.3 mutant line. Except for n-valerate (nC5), significant differences in all rumen fermentation parameters were observed among sorghum cultivars (p<0.05). Regarding the interrelationship between parameters, we found a medium correlation of DMD with the ADL and cellulose content of sorghum forage (R 2 = -0.489 and R 2 = -0.674, respectively). Based on these findings, the GH2.3 BMR mutant line should be further developed as forage sorghum.

“…Sorghum (Sorghum bicolor L. Moench) is the most produced crop in the world after wheat, rice, maize, and barley (Dahir et al, 2015). Sorghum has a wide adaptation and low input to grow on marginal lands (Mathur et al, 2017;Sriagtula et al, 2019). Sorghum has higher lignin content, which limits its consumption by ruminant animals due to conventional varieties of sorghum used is as a food and industrial crop (Sriagtula et al, 2017).…”

The mutant line of Brown-midrib sorghum has lower lignin content than conventional sorghum. The objectives of this research were to investigate the effects of plant maturity stages at harvest times on nutrient, fiber fraction, tannin content, volatile fatty acids (VFA) production, and in vitro fiber digestibility of mutant lines of Brown Midrib (BMR) sorghum. This research was arranged into a complete block design with a factorial arrangement in three replications. The first factor was a line of BMR sorghum consisted of 3 levels, i.e., Patir 3.1 (non-BMR line/control), Patir 3.2 (BMR line), and Patir 3.7 (BMR line). The second factor was the generative stages of sorghum consisted of 3 levels, i.e., flowering stage, soft-dough stage, and hard-dough stage. The observed variables were nutrient, fiber fraction, tannin content, in vitro rumen fluid characteristics, VFA proportion, acetate: propionate (A:P) ratio, and in vitro fiber-fraction digestibility (IVFFD). Data were analyzed by Analysis of Variance (ANOVA) and Duncan's Multiple Range Test (DMRT). No interaction between sorghum-mutant lines and harvest time on nutrient contents, except on total digestible nutrients (TDN), tannin, and VFA. The factor of sorghum-mutant line affected (p<0.01) crude protein (CP), crude fiber (CF), acid detergent fiber (ADF), lignin, neutral detergent fiber digestibility (NDFD), NH 3 , butyrate, isovalerate, and valerate. Maturity stages affected dry matter (DM), CF, ash, crude fat, fiber, and fraction, except hemicellulose, acid detergent fiber digestibility (ADFD), and NDFD, NH 3, isovalerate, and valerate. Patir 3.7 at the hard-dough stage produced the highest TDN, but the highest VFA was produced by Patir 3.1 at flowering stages. BMR sorghum-mutant lines produced higher ADF digestibility than non-BMR sorghum-mutant lines. The increasing NDF digestibility was significantly influenced by both sorghum-mutant lines and maturity stages (p<0.01). It is concluded that BMR sorghum-mutant lines at the hard-dough stage produce better nutrient and in vitro digestibility, but the butyric acid is higher in non-BMR sorghum-mutant lines.
