Content of Prussic Acid and Production of Sorghum Brown Midrib by Adding Urea Fertilizer and Extending Harvesting Time

Abstract. The aimed of this study to determine the effect of adding urea fertilizer (0, 50, and 100 kg/ha) and harvesting time (50, 80 and days) on prussic acid content and production of the brown midrib (BMR) sorghum plants. This study design was completely randomized factorial 3 x 3. The variables measured were prussic acid content, fresh yield, the production of dry matter (DM) and organic matter (OM). The results showed that content of prussic acid increased and highly significant with the addition of urea. The fresh yield of BMR sorghum is highest in the fertilization of 50 kg/ha and at the harvesting time 80 days. The highest DM production at fertilization 0 kg/ha and  harvesting time 110 day. OM production of the highest is the addition of fertilizer 0 kg/ ha and at the harvesting time on 80 days. From the results of this study concluded that on harvesting time 80 day sorghum  BMR have produces optimum and addition of urea to a level of 100 kg/ha did not affect the content of prussic acid, fresh yield, DM and OM

The Effect of Variety and Harvesting Time of Sorghum Planted in Stylosanthes Pasture on Growth, Production and Prussic Acid Content

This research was aimed to determine the growth, production and prussic acid content of sorghum variety that planted on stylosanthes pasture with different harvesting time. This research was done using split-plot design with three replications which sorghum variety (brown midrib resistance (BMR) and Super-2) as the main plot and harvesting time (6, 8 and 10 weeks) as the sub plot. The sorghum seeds were germinated for 12 days before planted on the 30 days stylosanthes pasture which was planted with planting space 25 x 25 cm. Sorghum was planted with planting space 75 x 25 cm. The variables observed were plants height, dry and organic matter production and prussic acid. Data obtained were analyzed statistically using analysis of variance and significantly different between means were tested with Duncan's New Multiple Range Test  (DMRT). Sorghum BMR had plant height, dry and organic matter production higher (P<0.05) than Super-2. Prussic acid content of BMR was lower (P<0.05) than Super-2. The older harvesting time increase (P<0.05) plant height, dry matter and organic production, but reduced (P<0.05) prussic acid content from 727.34 mg/kg to 241.71 mg/kg. Based on the results it can be concluded that the oldest harvesting time (10 weeks) produced the highest dry and organic matter, and reduce prussic acid content. Sorghum BMR is more productive and grew faster than Super-2. Sorghum BMR that harvested in 10-week shows the best in growth and productivity also had lower prussic acid content

The Effect of Harvest Age on Different Regrowth on Chicory (Cichorium intybus L.) Forage Yield by Intercropped with Pennisetum purpureum cv. Mott

This research was carried out to examine the chicory forage yields on different regrowth which were intercropped with Pennisetum purpureum cv. Mott (dwarf elephant grass) on different regrowth due to various harvest age. The research was conducted in the Laboratory of Forage and Pasture, Faculty of Animal Science UGM for 7 months, with a split-plot design and analyzed by Duncan with a total of 9 plots and an area of 2.5x2.5 m2 for each plot. The main plot was the harvest age treatment (30, 45, and 60 days) and the subplot was the regrowth (first and second). In the first stage, as many as 9 cuttings of dwarf elephant grass in one plot were planted with a spacing of 1x1 m2 until the plant height reaches 10 to 15 cm, then the chicory seeds were spread among the dwarf elephant grass plants with the sand mixture. The results showed the harvest age had a significant effect (P<0.05) on chicory's plant height, fresh forage yield, dry matter content, dry matter digestibility, and organic matter digestibility. The 30 to 45 days harvest age performed a higher fresh production more than the 45 days to 60 days harvest age. The 60 days harvest age and second regrowth yielded the highest mixed fresh production compared to the other harvest ages, namely from 12.50 ton/ha to 25.26 ton/ha. Based on the research results showed that the older the harvest age (60 days) increased the biomass of plant production but decreased the plant digestibility. The second regrowth was able to produce higher than the first regrowth, but there was no significant effect on the dry matter content and forage digestibility.

Effect of Different Beehives Size and Daily Activity of Stingless Bee Tetragonula Laeviceps on Bee-Pollen Production

Bee activities and colony may affect the production of bee products. Bee-pollen is one of the important products of honeybees, besides of honey. Tetragonula laeviceps is a group member of stingless bees found in tropical region. In Indonesia, Tetragonula laeviceps mostly create a nest in bamboos that make unfortunately difficult for harvesting of its products. The aim of this study was to investigate the effect of different beehives size and the daily activity (morning vs. afternoon) of stingless bee Tetragonula laeviceps on bee-pollen production. This study was conducted in Ngrandu, Katongan Village, Sub-district of Nglipar, Gunungkidul, Yogyakarta. Forty colonies of Tetragonula laeviceps were obtained from bamboos (similar in diameter and length) were transferred into four different group of beehives size (BS) made from dried wood, respectively: 35x17.5x13.5 (BS1); 35x20x17.5 (BS2); 37.5x20x20 (BS3) and 40x20x20 cm (BS4). Each group of beehives size had ten colonies/beehives as replicates. The colonies consisted of a queen bee, eggs, worker bees, and drones were transferred into wood beehives, and they were kept for two months for the study. The bee-pollen was harvested from beehives, separated from the propolis then weighed. The production of bee-pollen in the four different beehives size (BS1: 2.34±2.48 g/colony; BS2: 4.56±3.94 g/colony; BS3: 1.30±1.22 g/colony, BS4: 1.02±0.63 g/colony) was not different (ns) among the groups. The daily activity of bee bring the pollen to the nest in the morning (07.00 to 11.00) was significantly different (P<0.05) among the groups, but not significant (ns) different in the afternoon (14.00 to 17.00). The frequency of bringing in pollen into the hives at the morning is higher than at the afternoon (21.75 vs. 12.43 times/5 minutes). It could be concluded that the colony in beehive size of BS2 (35x20x17.5 cm) has higher daily activities and thus higher bee-pollen production, compared to the other beehives groups
