Thirty grass populations were evaluated for dry matter yield, N content, P content, organic matter digestibility and winterhardiness. Of these populations, Agropyron cristatum, A. desertorum, A. elongatum, A. intermedium, A. trachycaulum, A. trichophorum, Bromus inermis and Elymus junceus are used extensively for forage crops and E. angustus is being commercialized at present. Of the remaining populations, A. smithii, E. cinereus, Oryzopis hymenoides, E. akmolinensis, E. curvatus, Roegneria sibiricus, and Stipa viridula × O. hymenoides do not appear to have any potential as forage crops; whereas A. sibiricum, E. virginicus, E. sibiricus, A. caespitosum × A. caninum, A. caespitosum × A. trachycaulum, A. cristatum × A. desertorum (4n) show some potential and should be investigated further.

Twenty grass populations were evaluated for dry matter yield, N content, P content, organic matter content, organic matter digestibility and winterhardiness. Of these populations, Agropyron intermedium was most suitable for a hay crop on a well-drained irrigated soil. Agropyron trichophorum, Bromus inermis, and Phalaris arundinacea were lower-yielding alternatives that had a satisfactory N content and good digestibility. Elymus angustus shows promise as an irrigated hay crop and should be evaluated further. The usefulness of the following populations was limited by one or more of these factors: low yield (Y), low N content (N), low digestibility (D) and lack of winterhardiness (W): Dactylis glomerata ’Kay’ (Y,N,D), Dactylis glomerata ’Chinook’ (Y,N,W), Elymus sibiricus (Y), Festuca arundinacea ’Kenmont’ (Y,N,W), Festuca elatior ’Trader’ (Y,N), Phleum pratense (Y,N,D), Poa ampla ’Sherman’ (N,D), Poa bulbosa cv. P4874 (Y,N,D), and Poa pratensis (Y,N,D).

The effects of five times of irrigation, two times of N-fertilizer application and four rates of N-fertilizer application on the seed yield, dry matter yield, N, P, NO3-N, Ca, Mg, and K content and K/(Ca+Mg) ratio of Altai wild ryegrass (Elymus angustus Trin.), were studied from 1974 to 1977. No clear-cut methods to maximize the seed yield on irrigated land were found. Highest dry matter yields were obtained from grass given three irrigations and 400 kg N/ha per year. Spring applications of N fertilizer resulted in forage with a higher N content than fall applications. The N content of the forage increased with increasing levels of N fertilizer, whereas the P content of the forage was reduced by N fertilizer applications. Toxic levels of nitrates can be expected from spring applications of 400 kg N/ha. This danger was reduced if N fertilizer was applied in the fall. The Ca, Mg and K content increased with increasing levels of N fertilizer. The K/(Ca+Mg) ratio indicated that there was little danger of grass tetany problems in animals fed fertilized Altai wild ryegrass.

A study was conducted to determine the best agronomic practices for the cultivation of jerangau merah as a new medicinal crop. Jerangau merah is scientifically known as Boesenbergia stenophylla is a ginger plants that is highly endemic to the Borneo Highland. This understorey herb grows in cluster and under the heavy shades of forest canopies and perceived only the sunflecks that pass through the forest canopies. Jerangau Merah has been consumed by the locals for its medicinal values since decades ago. Generally, B. stenophylla is well known for its function as antidote for alcohol. Moreover, the B. stenophylla is also beneficial for rheumatic pains, remedies for stomach ache and toothache and as antiseptic wash as well. This herb is not propagate by the locals due to its sensitivity to sunlight and lack of agronomic information for B. stenophylla. Harvesting it from their natural habitat, however, seen the decline it its population size hence cultivation is essential. This paper aimed to determine the total nutrients, dry matter yield and phytochrome content of Bosenbergia stenophylla R.M. Smith under different light regimes. A study for determining suitable planting media for B. stenophylla was conducted at Universiti Putra Malaysia (UPM). The treatments are: i) (M1) with the ratio of 3:2:1 top soil: sand: organic matter, media ii) (M2) consists of soil mixture 3:2:1 placed in water-logged polyethylene bags and media iii) (M3) contained only leaf litters. The results showed that the herbs showed significantly higher number of shoots and leaves in the common soil mixture. But, better root development in media containing leaf litters. The study proceeded with field experiment at Ba’Kelalan to determine the effect of different shade levels and fertilizing regimes on growth. B. stenophylla was cultivated under two different levels of shade cloths: 70% and 90% level of shade and different fertilizing regimes (T1 as control, no fertilizer applied to the plants; T2, chicken dung; T3, NPKMg and T4, mixed of chicken dung and NPKMg). The study for determining the effects of different shade level and fertilizing regimes on seedling’s growth which conducted at Ba’Kelalan in factorial randomized completely blocked design (RCBD). The data collected for 9 weeks of planting which include nutrient content in soil, leaf, PAR and phytochrome content and growth parameters. Regarding the nutrient uptake, the results showed no interactions between fertilizing regimes and shade levels. There were no significant different in nutrient elements except for magnesium and potassium. Magnesium is essential for the formation of chlorophyll which ensure efficiency of photosynthesis when under higher light intensity. Among all the fertilizer treatment, it was showed that chicken dung amendment has higher nutrient uptake. Thus, it is recommended chicken dung should be added into the NPKMg for better nutrient uptake. Further study on suitable fertilizer rates apply to B. stenophylla should be taken into consideration. Moreover, plants cultivated under 70% have been higher and have higher dry matter yield than those plants cultivated under 90%. The result also revealed that there was significant different in chlorophyll content of B. stenophylla cultivated under 70% which treated either with chicken dung and NPKMG respectively. However, plants under 90% have higher chlorophyll content than those under 70%. Based on the results, plants under 70% shade was taller than those under 90% and there were significant difference in height among treatments under 70%.  It was observed plant treated with NPKMg was taller. This study showed that shade and fertilizers significantly affected the dry matter yield of B. stenophylla. Moreover, adding NPKMg to the treatments yields more dry matter content of jerangau merah. As for phytochrome content, there was no significant effect of fertilizer on phytochrome content. However, there was significant difference among the shade levels. 90% shade showed higher phytochrome content than those under 70%. In overall, both shade and fertilizer is important in cultivation of Jerangau Merah. 70% shade was observed to have significant effects on growth of jerangau merah and also more economical compared to 90%. Moreover, combination of organic matter and NPKMg also promote the growth of jerangau merah enhance the nutrient uptake efficiency of jerangau merah. However, further investigation of suitable fertilizer and application rate are required to determine suitable fertilizer for jerangau merah and application rate for optimum growth of jerangau merah.

The development of the yield and nutritive value of timothy (Phleum pratense L.) both in the primary growth and in the regrowth were studied at MTT Plant Production Research, a unit of MTT Agrifood Research Finland, in Rovaniemi (66°35´N) in 1999–2001. The dry matter yield and leaf:stem ratio were measured from the crop samples, and the contents of crude protein and organic matter digestibility of both whole plant samples and leaf and stem fractions were analysed. In primary growth, the most rapid increase of dry matter, 220–240 kg ha-1 per day, was measured around the beginning of the heading stage. There was a very strong positive correlation between the proportion of stems and the amount of dry matter in the primary yield. The daily growth rate of the regrowth was less than half of that of the primary growth. The fastest decrease, 1 percentage unit per day, in crude protein content was measured at the pasture stage (4–5-leaf stage). During the entire sampling period, the average daily decline in crude protein content in the primary growth of timothy was 0.65 percentage units. The main cause for the rapid decline in crude protein content was the high proportion of stem matter and its low protein content. In the regrowth, during the last four weeks before the harvest, the average daily decline in crude protein content was 0.28 percentage units.The average decline in organic matter digestibility from early pasture stage to late silage stage was 0.9 percentage units per day. The most remarkable change was noticed at the growth stage of timothy when about the half of stems were heading and it was then that the digestibility decreased by more than one percentage unit per day. The rapid decline in organic matter digestibility was due to the low digestibility of stem matter. The daily change in forage digestibility in the regrowth was very small, on average 0.11%.;

The experiment goal was to determine the supplementation effect of katuk leaves meal and Zn bio complex on dry and organic matter consumption and digestibility of postweaning male of Ettawa Crossbred. The experiment used sixteen heads of the postweaning male of Ettawa Crossbred aged 4-5 months with an initial body weight of 9.01±1.85kg (CV 20.55%). Completely Block Randomized Design (CBRD) with 4 treatments and 4 replications were applied in this experiment. Those treatments were P0: Lamtoro + concentrate without katuk leaves meal and Zn biocomplex (control); P1: P0 + 5% katuk leaves meal (on the basis of forage dry matter)  and Zn bio complex; P2: P0 + 10% katuk leaves meal (on the basis of forrage dry matter) and Zn bio complex; P3: P0 + 15% katuk leaves meal (on the basis of forage dry matter) and Zn bio complex. Variables measured were dry matter (DM) consumption, organic matter (OM) consumption, DM digestibility, and OM digestibility. Average of DM  consumption were P0 (326.68 ±44.13g/h/d), P1 (351.68±63.47g/h/d), P2 (351.78±33.41g/h/d) and P3 (346.24±32.48g/h/d). Average of OM consumption were, P0 (300.38 ±41.14g/h/d), P1 (316.11±57.05g/h/d), P2 (315.54±30.83g/h/d) and P3 (309.21±29.00g/h/d). Average of DM digestibility, P0 (78.94 ±4.67%), P1 (78.77±9.54%), P2 (64.82±11.45%), P3 (75.38±14.56%). Average of OM digestibility, P0 (81.17±4.01%), P1 (80.77±8.69%), P2 (68.79±9.90%), and P3 (76.93±12.77%). The result of variance analysis showed that treatment has a significant effect (P<0.05) on dry and organic matter consumption but no significant (P>0.05) on dry and organic matter digestibility It can be concluded that supplementation of of katuk leaf meal (Sauropus androgynus L. Merr) at 5% up to 15% and Zn bio complex might increase dry and organic matter consumption of postweaning male of Ettawa crossbred.

This study was conducted in Nutrition Lab. to investigate the effect of the type and level of substitution of urea with ruminant manure, M (sheep, cow and buffalo) on basis of nitrogen (N) content on the nutritive value of rice straw silage (RSS). Accordingly silages were nominated as, S-RSS, C-RSS and B-RSS. Urea (U) was substituted with dried manure at 6 combinations, 100:0, 90:10, 80:20, 70:30, 60:40 and 50:50 of U:M. Silage samples were prepared by treating chopped straw with pre-treated solution contained 10% low quality debis and 2% urea. Results showed that lower (P˂0.01) DM loss (11.4%) was observed in S-RSS, and with addition of urea only (3.6%).        Samples of S-RSS and C-RSS recorded higher (P˂0.01) Fleig points (Fp) as compared with those prepared by the addition of B-RSS, 60.42, 55.58 and 49.59 respectively. Reduction (P˂0.01) in this parameter was noticed in samples prepared with a combination of 100:0. Aerobic stability (AS) was a reduced (P˂0.01) in samples prepared by addition of S-RSS by 15 and 13 hours in comparison with samples of C-RSS and B-RSS respectively. Samples prepared with combination of 100:0 were prior (P˂0.01) as compared with other samples.        Results also showed an increase (P˂0.01) in in vitro digestibility of organic matter (IVOMD) in samples of S-RSS in comparison with samples prepared by addition of C-RSS and B-RSS, 49.99, 44.59 and 42.77% respectively. Samples prepared with combination of 100:0 recorded lower (P˂0.05) in vitro digestibility of dry matter (IVDMD) as compared with combinations of 70:30 and 60:40 of U: M, 40.52, 45.36 and 45.94% respectively.

The influence of the improved drainage broadbed and furrow (BBF), as opposed to the traditional flat seedbed over the growing season on the dry matter yield and nutritive value of Avena sativa, Vigna unguiculata, Lablab purpureus, Vida dasycarpa, Trifolium steudneri and Sesbania sesban were studied on Vertisol. Up to 7 t/ha dry matter yield was recorded for Avena sativa and Lablab purpureus when planted on Vertisols with improved drainage. Dry matter yield of forage crops also increased with advance in stage of maturity or subsequent harvests. On both improved and traditional flat seedbed methods, the chemical analysis of forage crops showed similar declines in crude protein content and in vitro dry matter digestibility (IVDMD) levels as the maturity of forage crops progressed.

<p>The development of sheep livestock is done as a comodity producer to meet the need of the meat. To increase the productivity of the sheep, the feed have a certain quality with the mix of worm flour. This research aims to determine the influence of the use of worm flour (Lumbricus rubellus) concerning to dry and organic matter digestibility lokal male sheeps feed. This research was conducted in the enclosure of research at the Faculty of Agriculture, Animal Husbandry Department of the Universitas Sebelas Maret Surakarta which is located in the Village Jatikuwung, Gondangrejo District, District Karanganyar. Research was conducted from December 28th, 2008 to February 22nd, 2009 using the 12 local male tail sheep with body weight on average 13.82 ± 0.73 kg / head. Feed given at 6% of body weight consist of a concentrate forage and comparison with 70:30 per cent (basic dry matter). Utilized of the concentrate made of a mixture that consist of bekatul, oilcake soybean, corn flour, worm flour, and premix while forage given a field grass. Feed treatment used field grass 70%, concentrate 30% (P0); field grass 70%, 28% concentrate, worm flour 2% (P1); field grass 70%, 26% concentrate, worm flour 4% (P2) and 70% field grass, 24% concentrate, worms flour 6% (P3). Experimental design used was the Complete Random Design (CRD) pattern, the direction of the 4-level treatment (P0, P1, P2, and P3). Each treatment consist of 3 test replications and the replications each of one local male sheep. Parameter observed: dry matter consumption (DMC), organic matter consumption (OMC), dry matter digestibility (DMD), and organic matter digestibility (OMD). Results of research indicate that the average of the four treatment (P0, P1, P2 and P3) respectively for the dry matter consumption 858.35, 876.57, 881.55 and 887.58 (grams/ head/ day), organic matter consumption 670.32, 682.04, 686.16 and 689.03 (grams/ head/ day), dry matter digestibility 55.17, 59.51, 57.19 and 58.84 percent and organic matter digestibility 66.28, 69.09, 67.21 and 68.12 percent. Variansi analysis results show that the dry matter consumption, organic matter consumption, dry matter digestibility, and organic matter digestibility is not significantly different (P ≥ 0.05).
