Forage, the main feedstuff for ruminants, includes grasses and legumes, browses, and side products of food crops. However, legumes generally have greater crude protein content relative to other species of forage plants. One of the species of legumes is alfalfa (Medicago sativa), a perennial crop that can grow from the tropics up to sub tropics. In spite of its excellent nutrient content, In Indonesia alfalfa is still not widely explored and used for feedstuff. A study was conducted to explore and evaluate of alfalfa performances in terms of the height, number of tillers, dry matter (DM) and crude protein (CP) productions under the effects of different plant densities and ages of defoliation”. The height of the location of study was 200 m above sea level with an average temperature of 270 C. The results showed that the ranges of the height of alfalfa, the numbers of tillers, DM and CP productions were 33.31-56.32 cm, 36.38-82.36 tillers/bunch, 556.9-1018.9 kg/ha/defoliation, and 149.75 – 291.79 kg/ha/defoliation, respectively. In general, the ages of plant at the time of defoliation and plant distances affected (P<0.05) the variables being studied. The older plants resulted in greater DM and CP yields, and more densely plantation resulted in greater DM and CP yields.Keywords: alfalfa, plant density, defoliation age.

Abstract. Suwignyo B, Arifin L, Umami N, Muhlisin, Suhartanto B. 2021. The performance and genetic variation of first and second generation tropical alfalfa (Medicago sativa). Biodiversitas 22: 3265-3270. This study aimed to compare the growth performance, nutrient content, seed viability, and genetic variation of first- and second-generation alfalfa (Medicago sativa L.). First and second-generation alfalfa seeds were obtained from the Forage and Pasture Science Laboratory, Department of Animal Nutrition and Feed Science, Faculty of Animal Science, Universitas Gadjah Mada (UGM), Yogyakarta, Indonesia. First generation alfalfa (F1) seeds were obtained from cross breeding of two different parental alfalfa varieties, namely, Canadian and local. The second-generation (F2) seeds were obtained from plants of the first-generation alfalfa (F1). A randomized design experiment was conducted using the two types of alfalfa (first- and second generation). Alfalfa from Canada as female parent was used as the baseline in the genetic masker test. Seeds were planted in a polybag, watered twice a day, and received 12 hours of daylight and 4 hours of artificial light. Plants were then harvested 8 weeks after planting by cutting the plant canopy. Genetic variation was examined using the Inter Simple Sequence Repeat (ISSR) method followed by descriptive analysis. Germination, plant height, dry matter content, organic matter, and crude protein were assessed as variables using a Student’s T-test. Our results showed that germination, plant height, leaf color, and nutrient content (dry matter, organic matter, and crude protein) of the first- and second-generation alfalfa plants were not significantly different. However, the second-generation alfalfa demonstrated better seed viability than the first generation plants, then it can be categorized as a new genotype (tropical alfalfa) based on genetic variation analysis.

Abstract Background Understanding the relationship between dry matter yield production and forage quality throughout the growing season will help to optimize the cutting intervals between harvests in different Alfalfa (Medicago sativa L.) varieties. An experiment was conducted to assess the effects of harvest frequency on forage yield and quality of 2 improved cultivars (ILRI-6984 and var. DzF-552) of alfalfa (Medicago sativa L.) in Western Dembia district over 20 months during 2017 and 2018. Four harvest frequencies (every 30, 40, 50 and 60 days) were compared in a randomized complete block design (RCBD) with 4 replications. The experiment was laid down in a randomized complete block design (RCBD) in factorial arrangement with four replications. To assess their production potential plant height (cm), number of branches per plant, fresh biomass yield (t ha−1) and dry matter yield (t ha−1) of the forge and its nutrient content were recorded. The data collected was subjected to analysis of variance (ANOVA) by using the general linear model (GLM) procedure in Statistical Analysis System (SAS) (2003) version 9.1. Results The results revealed that highest forage dry matter yield was recorded for variety ILRI-6984 harvested every 40 days (26.8 t DM ha−1) and for var. DzF-552 when harvested every 60 days (24.1 t DM ha−1) (P<0.001). While crude protein concentration tended to decline as age at harvest increased, there was little consistency in the pattern. Crude protein yields were also inconsistent across treatments but ILRI-6984 harvested every 40 days produced the highest yields (6.5 t ha−1) (P<0.001). Conclusion These preliminary findings need to be confirmed under field conditions on a large scale along with longer-term studies to examine the longevity of the stands at these harvest frequencies. Irregular harvesting based on stage of maturity should be compared with fixed inter-harvest intervals.

This study was conducted to investigate the effect of plant density on biomass yield of maize fodder, its acceptability and digestibility by Sokoto Gudali heifers. Treatments P1, P2, P3 and P4 correspond to different plant densities of 53,333, 106,666, 210,526 and 421,072 plants/ha, respectively. Each treatment was replicated three times on 4m x 10m plots and fertilizer was applied as100 kg N/ha. Fodder was harvested at 6weeks of age (42 days after planting) and weighed to determine the biomass yield. Samples were also taken for chemical analysis. Harvested fodder were fed to Sokoto Gudali heifers to determine its preference and digestibility. Biomass yield increased significantly (P<0.05) within plant population with P4 (3.55 tons/ha) having the highest yield and P1 (1.61 tons/ha) having the least. Dry matter (DM, 23.64 – 27.22%) and crude protein (CP, 19.75 – 27.50%) of fodder increased as plant population increased while fibre components (ADF, NDF AND ADL) decreased. In this study, an increase in plant density produced more forage yield of very good quality with high dry Matter digestibility and no variation (P>0.05) in the preference by the animal.

ABSTRACT The objective of this work was to evaluate the effect of plant densities and sidedressed nitrogen (N) rates on nutrition and productive performance of the common bean cultivars IPR 139 and Pérola. For each cultivar, a randomized complete block experimental design was used in a split-plot arrangement, with three replicates. Plots consisted of three plant densities (5, 7, and 9 plants ha-1) and subplots of five N rates (0, 30, 60, 120, and 180 kg ha-1). Aboveground dry matter, leaf macro- and micronutrient concentrations, yield components, grain yield, and protein concentration in grains were evaluated. Lower plant densities (5 and 7 plants m-1) increased aboveground dry matter production and the number of pods per plant and did not reduce grain yield. In the absence of N fertilization, reduction of plant density decreased N concentration in common bean leaves. Nitrogen fertilization linearly increased dry matter and leaf N concentration, mainly at lower plant densities. Regardless of plant density, the N supply linearly increased grain yield of cultivars IPR 139 and Pérola by 17.3 and 52.2%, respectively.

The effects of early summer and fall cutting managements on two alfalfa (Medicago sativa L.) cultivars were studied over a 3-year period. Removal of the first crop of Saranac and Narrangansett alfalfas at prebud stage, followed by two cuts at the early bloom stage before early September, and a late fall harvest on October 25, produced seasonal dry matter (DM) yields of 7.5–8.6 metric T/ha in the 1st year. Stand deterioration, however, was severe and by the 3rd year, practically all alfalfa had disappeared. Average percent crude protein (CP) in cut 1 was 17.7–21.9 and percent in vitro dry matter digestibility (IVD) 67.4–73.8. Removal of the first cut at bud stage with two subsequent harvests at the early bloom stage also allowed a total of three harvests before early September and resulted in seasonal DM yields of 8.6–8.8 in the 1st year. Although the survival of alfalfa was increased over the managements where cut 1 was at prebud stage, a considerable decrease of alfalfa was still observed in the 3rd year. Under this management, average CP in cut 1 was 15.8–16.3 and IVD 64.1–68.4. Harvesting the first crop at early to midbloom stage and the second crop at early bloom in early to mid-August, followed by third harvest in late October, resulted in good survival with seasonal DM yields of 6.1–10.6. Lower CP and IVD were recorded in cut 1 than in the more intensive managements. Under all managements, average CP in cuts 2 and 3 was 14.9–17.3 and 13.3–19.4, respectively. IVD was 54.5–60.7 in cut 2 and 56.0–64.4 in cut 3.

 ABSTRAK Ketersediaan hijauan pakan ternak haruslah memenuhi aspek kuantitas, kualitas dan kontinyuitas. Teknologi pengawetan pakan dengan membuat silase berbahan tanaman pakan yang sesuai diharapkan dapat memenuhi kebutuhan pakan tersebut. Sorgum memiliki potensi sebagai bahan silase yang baik namun perlu ditingkatkan kualitasnya dengan menambahkan hijauan yang tinggi kandungan protein kasarnya. Penelitian ini bertujuan untuk mengevaluasi kualitas dan karakteristik fermentasi silase kombinasi sorgum dan leguminosa. Penelitian ini dilakukan dengan mengkombinasikan Stay green dan Indigofera zolingeriana (100:0, 60:40, 50:50, dan 40:60%) sebagai bahan silase untuk dievaluasi pH, kandungan bahan kering (BK), bahan organik(BO), protein kasar (PK) dan Nilai Fleigh. Silase dibuat dalam silo ukuran 1 liter yang difermentasi selama 21 hari. Hasil penelitian menunjukkan bahwa meningkatnya persentase Indigofera zolingerianadalam silase meningkatkan pH silase, BK, dan PK silase. Peningkatan pH tersebut berakibat pada terjadinya proteolisis pada PK silase. Penggunaan Indigofera zolingeriana dalam silase kombinasi dengan sorgum Stay green pada persentase 40% masih memungkinkan untuk memperoleh silase kombinasi yang berkualitas baik (Nilai Fleigh 70,13) dan kandungan protein kasar mencapai 15,68%. Kualitas tersebut selanjutnya akan menurun apabila persentase Indigofera zolingeriana dinaikkan walaupun kandungan protein kasar meningkat.Kata Kunci: Silase, Kombinasi, Kualitas, Evaluasi, Nilai Fleigh.ABSTRACTFeed availability has to meet quantity, quality and continuity aspect. Feed preservation technology by making silage from suitable forage plants is expected to meet these needs. Sorghum has the potential as a good silage material but needs to be improved in quality by adding other forage which have high crude protein content. This study was aimed to evaluate the quality and characteristics fermentation of sorghum and legumecombination silage. This research was conducted by combining Stay greensorghum and Indigofera zolingeriana (100: 0, 60:40, 50:50, and 40: 60% combination) as silage material to be evaluated for pH, dry matter content (DM), organic matter (OM), crude protein (CP) and Fleighpoint. Silage was made in 1 liter size silos which are fermented for 21 days. The results showed that the increasing percentage of Indigofera zolingeriana in silage could increase silage, pH, DM, and CP silage. The increase in pH resulted in proteolysis of silage protein. The added of Indigofera zolingeriana in silage combination at 40% was still possible to obtain good quality silage (Fleighpoint 70.13) and reaching 15.68% of silage CP content. The silage quality was decrease if the percentage of Indigofera zolingeriana increased, even though the silage CP content could increasesafterward.Keywords: Silage, Combination, Quality, Evaluation, Fleigh point

Trials were conducted at Gangora in the northern Guinea Savanna ecological zone of Nigeria during the 1990 and 1991 rainy seasons. The effects of date of planting (4th,14th, 24th June and 4th  July) and levels of nitrogen fertilizer (0, 50,100, 150 and 200kg/ha) on growth components of Sorghum almum  were investigated. Planting in mid-June (14th June) in 1990 and early-July (4th July) in 1991 resulted in superior stand established and dry matter yields (p<0.05) than other dates. In mid-June and early-July planting 14 day post-planting, plant densities were 7.0 and 9.0 culms/m2 while plant heights were 20.4 and 11.3cm for the respective years. It had high tillering capacity and irrespective of date of planting (except for early-June planting) plant densities by 56 days post-planting (DPP) were greater than 100 culms/m2. Plant height at this stage were greater than 100 culms/m2 and were generally above 200cm. ninety DPP the pasture was at full bloom/hard dough stage. Dm yields then ranged from 8.0 to 11.4 tDM/ha in 1990 and 9.6 to 14.7 tDM/ha in 1991. Similarly seed yield for the respective years were 894.7 and 836.3 kg/ha. Fertilizer application (p<0.05) plant vigour, tillering and dry matter yield up to the highest N applied. In the first years trial, plant density at 35 days post-planting ranged from 12.0 to 29.0 culms/m2 while in the second year the ranged was 13.0 to 26.0 culms/m2. The corresponding values at 56 DPP (i.e 42 days following N application) were 32.0 to 81.0 and 45.0 to 101.0 culms/m2. Dry matter yields rose steadily from 6.5 to 12.5 tDM/ha in 1990 and from 8.9 to 13.6 tDM/ha in 1991 as fertilizer was increased 0 to 200 kgN/ha. Seed yield during the same period for the respective years varied from 416.0 to 753.0kg/ha. This study has shown that planting between mid-June and early-July with fertilize application of 100 to 200 khN/ha favour S. almum establishment and production in the northern Guinea Savanna of Nigeria

<p class="awabstrak2">The obstacle in planting and developing forage plants is limited land. One solution to anticipate this is to utilize land in plantations by introducing forage shade-tolerant among the main crops. The area of oil palm plantations in Indonesia reaches 14,677,560 ha potentially used in the integration system. This article outlines the superiority of <em>Stenotaphrum secundatum</em> from the selection results so that the reader gets comprehensive information about this grass, both in terms of production, nutritional quality and digestibility. <em>Stenotaphrum secundatum</em> selection’s variety grass is a forage shade tolerant that had derived by positive mass selection method which had had been tried it’s adaptability at two different elevation in North Sumatra. This grass is very suitable to be integrated in plantation land. The average fresh yield of <em>S. secundatum</em> at 55 and 75% shading level reached 2,386 and 2,001 g/m2/harvest, respectively. The digestibility of Steno grass selection’s result on growing Boerka goat shows a fairly good value, which ranges from 60.7% to 72.8%. Palatability of <em>S. secundatum</em> grass in goats is very good with consumption reaching 3.6% of body weight. <em>S. secundatum</em> grass, besides being tolerant of shade, is also resistant to pests, as long as it is maintained with good management. The crossing of polyploid Steno grass with diploid has produced drought tolerant varieties. This grass also has advantages in terms of dry matter production, nutrient content and crude protein production compared to other grass species and can be planted in wider plantation areas with 55-75% shade.</p>

Fluazifop-P, applied in the spring or fall and pronamide, applied in the fall only, reduced quackgrass infestation in established alfalfa and increased the dry matter yield of alfalfa. Herbicides did not improve alfalfa in vitro digestibility or crude protein content. Average residues of fluazifop-P in alfalfa treated with rates of 0.25 or 0.5 kg ai ha–1, were 0.1 mg kg–1when harvested 280 d after application, and 0.06 mg kg–1when harvested 295 d after application. Average residues in alfalfa harvested 41 and 55 d after application were 0.13 mg kg–1and 0.1 mg kg–1, respectively, with a 0.25 kg ha–1treatment and 0.19 mg kg–1and 0.05 mg kg–1, respectively, with a 0.5 kg ha–1treatment.

The aim of this study was to determine the degradation in the rumen for the dry matter (DM), organic matter (OM) and crude protein (CP) of alfalfa (Medicago sativa L.) harvested at different maturity stages by using an in situ nylon bag method. Maturity and harvesting effects were observed in ruminally degradable DM, OM and CP. High correlations between in situ degradability and maturity were determined. Alfalfa harvested in the bud period exhibited more extensive ruminal DM, OM and CP degradation than that harvested at other maturity stages. The alfalfa hay’s DM, OM and CP degradability were lowest (62.18%, 59.52% and 76.31%, respectively) in its most mature period of seed setting; its degradability decreased with maturity (17%, 14% and 13%, respectively).
