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.

The purpose of this study was to determine the effect of gamma-ray irradiation on Sorghum sudanense in the first offspring (F1) on plant growth, production, and lignin content at different harvest ages. This study used a split-plot design in which varieties of Sorghum sudanense with gamma irradiation and Sorghum sudanense without gamma irradiation are the main plot. Meanwhile, the harvest age is the subplot. The planting area was 1.5x1.5 m, each with 3 replications. The materials used were Sorghum sudanense without gamma-ray irradiation and the first generation seeds (F1) of Sorghum sudanense with gamma irradiation. The method used was irradiating Sorghum sudanense seeds with gamma-ray with a dose of 300 Gy, planting, maintenance, and harvesting. The harvest ages were 50, 70, and 90 days. The data observed were plant growth, namely plant height and length, dry matter (DM) and organic matter (OM) production, and lignin content. Sorghum sudanense with gamma irradiation had higher plant height, plant length, also DM, and OM production (P<0.05) than Sorghum sudanense without gamma irradiation. The lignin content of Sorghum sudanense with gamma irradiation was lower (P<0.05) than Sorghum sudanense without gamma irradiation. Longer harvest age increased (P<0.05) plant height, plant length, production, and lignin content. In conclusion, there were characteristics differences between Sorghum sudanense with gamma irradiation and without gamma irradiation (parents). The longer harvest led to higher plant height, length, production, and lignin content. There was an interaction (P<0.05) between varieties and harvest ages. Gamma irradiated Sorghum sudanense had a peak production at the age of 70 days, with a lignin content of 3.63%.

Fermented complete feed (CF) based forage-fodder and agricultural by product as feed for ruminants can be implemented in the household and industrial purpose. Complete feed technology is one of alternative to solve the problems of stock and quality of feed. The nutritional value can be set by determine the number and type of mixture, livestock will not has an opportunity to choose so that it can minimize residual feed, practical, and can be stored for long periods. Fermented complete feed very much match to be implemented in the dry season or in the emergency situation. During Merapi Volcano eruption in 2010 was one of moment which is need CF technology. Rice straw can used for CF that can be socked during dry season, also the quality might improve (from 3—4% of crude protein content became 7—8%) with addition of rice brand or other ingredients. Fermented complete feed based on rice straw, forage-fodder or agricultural by product has a multifungtion in the emergency situation, reduce disaster risk, and feed security conservation.

Sorghum is a potential feed crop to be developed in the tropics that has a long dry season such as in Indonesia. This study aims to determine the effect of harvesting age and nitrogen fertilizer level on the production and nutrient content of sorghum plants Numbu varieties. This study used a split block design with 2 factors and the difference between averages was tested with Duncan's Multiple Range Test (DMRT). The main factors are the age of harvest time consisting of U1 (50 days), U2 (60 days) and U3 (70 days). The second factor is the nitrogen fertilizer level which consists of P1 (0 kg / ha), P2 (100 kg / ha), and P3 (200 kg / ha). Each treatment was carried out 3 replications. The results showed that growth and production were influenced by harvest age and fertilizer level. The nutrient content of sorghum plants of Numbu variety which is influenced by harvest age is only BK, BO and SK, the contents of PK and LK, are not affected by harvest age. The highest BK content in treatment U3 (22.55%). The highest BO content in U3 treatment (91.90%). The highest SK content was in treatment U3 (38.56%). The content of PK and SK was significantly influenced by the nitrogen fertilizer (P <0.05), while the content of BK, BO and LK, was not significantly different. The highest PK content in treatment P3 (7.58%). The lowest SK content was P3 treatment (34.78%). These results indicate that the use of nitrogen fertilizers up to 200 kg / ha can increase (P <0.05) crude protein content, and reduce crude fiber content.

Abstract Weed is one of the plants that grow around rubber plantations that have the potential to provide forage for ruminant feed. This study aimed to explore the environmental conditions and identify the botanical composition of weeds under the shade of rubber trees in immature plants (IP) at PTPN IX, Getas Farm, Semarang, Central Java. Exploratory research was conducted to identify the botanical composition of weeds in three IP groups, such as 1-2, 3-4, and 5-6 years old. The composition of the weedsâ€™ botany was divided based on the plantsâ€™ morphology into grass, legume, forbs, and browse. The environmental conditions data were analyzed using the ANOVA method and followed by Duncan's Multiple Range Test (DMRT). The botanical composition data were tabulated using a summed dominance ratio (SDR). The results showed the light intensity, wind speed, environment temperature, and weed botanical composition decreased as the rubber plants ages. The composition of rubber plantation weeds on IP 1-2 years old consisted of 32 species (5 kinds of grass, 4 legumes, 21 forbs, and 2 browse). The composition of weeds on IP 3-4 years old consisted of 15 species (8 kinds of grass, 2 legumes, and 5 forbs), while IP 5-6 years old consisted of 6 species (4 kinds of grass, 1 legume, and 1 forb). The dominant weeds of each IP were Calopogonium mucunoides, Cyrtococcum acrescens, and Cyrtococcum oxyphyllum, respectively. Based on the results of the study it was concluded that the area of IP 1-2 years old rubber plantation weeds has the highest botanical composition and potential as ruminant feed.

The glass house experiment involving compost tea and harvest age was conducted to investigate the effect of giving compost tea (cricket and rabbit feces) and harvesting age on productivity, nutrient content, and in vitro digestibility value of Cichorium intybus. Compost tea (CT) is an aqueous extract from compost that can correct nutrient deficiencies during crop production and protect cultivation. The research treatment consisted of two factors, namely: the age of harvest and the dose of compost tea. The administration of compost tea consisted of three kinds of doses as follows: no compost tea (P0), 200 mL of compost tea (P1), and 400 mL of compost tea (P2). The experimental plants were harvested at different age, consisting of 25, 35 and 45 days after planting (DAP). The experimental design was Factorial Completely Randomized Design (CRD) with 6 treatments and 9 replications. The data were statictically analyzed using analisys of variance, and differences among value of each treatment were tested with the Duncan Multiple Range Test. The results indicated that compost tea dose and harvesting period treatment affected (P<0.05) leaf length, fresh leaf weight, crude protein content, dry matter digestibility (DMD), and organic matter digestibility (OMD). Meanwhile, it showed not significant effect (P>0.05) on the leaf width and root length. The results suggest that the fertilization treatment of 200 mL of compost tea and 25 DAP could increase productivity (leaf length and fresh leaf weight) of chicory, nutrient content (crude protein) of chicory, and in vitro digestibility (DMD and OMD).
