We studied the biochemical composition, nutritive value of the green mass and prepared hay from Ro-manian cultivars of perennial ryegrass, Lolium perenne L. „Mara” and „Măgura” grown in monoculture on the experimental plot of the National Botanical Garden (Institute) “Alexandru Ciubotaru”, Chisinau, R. Mol-dova. Results revealed that dry matter of harvested green mass contained 98-116 g/kg CP, 299-326 g/kg CF, 71-77 g/kg ash, 329-353 g/kg ADF, 546-593 g/kg NDF, 38-40 g/kg ADL, 291-313 g/kg Cel, 217-240 g/kg HC, with nutritive and energy value 60.9-65.3 % DMD, 60.1-64.8 % ODM, RFV=96-108, 12.12-12.45 MJ/kg DE, 9.95- 10.23 MJ/kg ME and 5.97-6.25 MJ/kg NEl. The biochemical composition, nutritive and energy va-lue of prepared hay: 94-110 g/kg CP, 351-385 g/kg CF, 79-82 g/kg ash, 390-423 g/kg ADF, 631-689 g/kg NDF, 46-50 g/kg ADL, 344-373g/kg Cel, 241-266 g/kg HC, RFV=76-86, 11.13-11.61 MJ/kg DE, 9.14- 9.53 MJ/kg ME and 5.17-5.55 MJ/kg NEl. The biochemical methane potential of green mass substrates reached 338-344 L/kg organic matter. The studied cultivars of Lolium perennec could be used in the Republic of Mol-dova for the restoration of degraded permanent grasslands, as a component of the mix of grasses and legumes for the creation of temporary grasslands, the harvested biomass can be used as feed for farm animals or as substrate in biogas generator for renewable energy production.

The flora of the Altai Mountains is characterized by a rich variety of representatives of the Fabaceae family, which are found in a wide range of habitats and under various anthropogenic loads. The genera Astragalus L. and Oxytropis DC. are the most numerous in terms of species diversity. Many representatives of the genera Vicia L., Trifolium L., Hedysarum L., Latirus L., Melilotus Mill., Medicago L., Pisum L. are good forage plants. The vegetation in the steppe grasslands of the Altai Mountains indicates the presence of predominantly intensive grazing farm animals, in which there is the formation of transient communities by reducing the participation of the prey species and the role of not eaten, eaten bad, harmful and poisonous plants. At the same time, the share of the legume component in the living ground phytomass in meadow steppes is quite high (25–50 %), in real steppes it is about 5–28%, and in desolate steppes – 11–17 %, which is largely due to the species diversity of legumes and their adaptability to natural, climatic and anthropogenic factors. Species Onobrychis arenaria, Medicago falcata are found in the meadow steppe, and Astragalus austrosibiricus, A. tibetanus, A. brevifoliu, and Oxytropis argentata are found in the steppe pastures, which develop a good green mass and have relatively high morphometric indicators. Astragalus testiculatus, A. laguroides, A. dilutes, Oxytropis pumila, Hedysarum gmelinii, Gueldenstaedtia monophylla, and harmful pasture plants – Thermopsis mongolica, Caragana pygmaea – are adapted to drier stony habitats. Of the wild relatives of cultivated plants from familia Fabaceae in the flora of the Altai Mountains there are more than 10 species. According to the results of environmental testing of 13 varieties of annual legumes (Vicia L., Pisum L., Glycine L.), it was found that they are characterized by higher rates of green mass yield (by 12–16%) than traditional varieties of these crops in the mid-mountain zone of the Altai Republic.

Lolium Perenne L

The thermal time, expressed in accumulated growing degree-days (AGDD), was used as a predictor to describe and simulate the independent growth of two pasture crops, Lolium perenne L. and Bromus valdivianus Phil. Two sinusoidal models (four-parameter Logistic and Gompertz) were applied to the growth variables (total leaf blade length per tiller—LBL, and accumulated herbage mass—AHM). The nutritive value of pastures was predicted and modeled using regression equations (linear and quadratic), depending on each nutrient. Data for modeling were collected from a two-year study, in which LBL, AHM, and nutritive value variables for L. perenne and B. valdivianus pastures were measured at three-day intervals. Defoliation was determined according to the AGDD, such that the swards were defoliated at 90, 180, 270, 360, and 450 AGDD. The Logistic and Gompertz models presented similar values for the growth rate (GR) parameters, superior asymptote (Asup), inferior asymptote (Ainf), and point of maximum growth (Pmax). In both species, the maximum growth was 260 AGDD. The GR was similar for both species in different seasons of the year, but the maximum AHM varied, with B. valdivianus presenting a higher value (+1500 kg DM ha−1) than L. perenne during the spring. The regressions accurately described the nutritive value, demonstrating a positive linear relationship between the AGDD and concentrations of neutral and acid detergent fiber (NDF, ADF), an inverse linear relationship with crude protein (CP), and a quadratic relationship with metabolizable energy (ME) and water-soluble carbohydrate (WSC) concentration.

Giant knotweed Polygonum sachalinense, weyrich's knotweed Polygonum weyrichii and spread wide knotweed P. divaricatum species from the collection of nontraditional fodder plants, Botanical Garden (Institute) of Academy of Sciences of Moldova, as objects of study have been served. The annual productivity of P. sachalinense was 12.42 kg/m2 of fresh mass or 3.09 kg/m2 of absolutely dry matter, P. weyrichii - 7.70 kg/m2 or  2.15 kg/m2 and P. divaricatum - 5.35 kg/m2 and 1.45 kg/m2 respectively. The species P. sachalinense is characterized by a protein (16.48%) and fat content (2.53%) at the level of fodder legumes. The content of these substances is lower in the species P. weyrichii and P. divaricatum compared with P. sachalinense but higher than in traditional forage crops: corn, sudan grass and sunflower. The nutritive value of natural fodder of species of the genus Polygonum is characterized by 0.20 to 0.23 nutritive units with a metabolizable energy content for cattle of 2.43 - 2.87 MJ / kg. The species P. sachalinense has a higher nutritional value of the natural fodder and is used in the production of quality silage.

Summary. Seasonal variation in herbage yield, and in the concentrations of water-soluble carbohydrates, crude protein, in vitro dry matter digestibility, neutral detergent fibre, acid detergent fibre and lignin in the herbage was measured for 5 perennial ryegrass (Lolium perenne L.) cultivars grown in 3 contrasting environments. Two separate trials were sown in one of the environments. The yield and nutritive value data were subjected to antedependence analyses to detect the presence of serial correlations between data from different harvest dates. Significant (P<0.05) antedependence was found in 2, 3, 3 and 6 of the 7 variables in the 4 experiments respectively. It was shown that serial correlations between harvest dates had the potential to cause the overestimation of the significance of cultivar effects in ANOVA of data from individual harvest dates, and in harvest and cultivar × harvest effects in combined ANOVA across all harvest dates unless statistical procedures appropriate for use with repeated measurements data were adopted.

A tenyészedényes kísérletünket a DE AGTC MÉK Agrokémiai és Talajtani Intézet tenyészházában állítottuk be 2010. május 27-én. A kísérletben Debrecen-Látókép környékéről származó mészlepedékes csernozjom vályogtalajt alkalmaztunk, amely az alábbi jellemzőkkel rendelkezett: KA: 37,5; leiszapolható rész: 51%; pH(KCl): 5,5; pH(H2O): 6,6; Hu%: 2,8; AL-P2O5: 140 mg·kg-1; AL-K2O: 316,3 mg·kg-1. Az adatok alapján a kísérleti talaj gyengén savanyú, vályog kötöttségű, közepes nitrogén- és foszfor-, valamint jó kálium-ellátottsággal rendelkezett. A kísérletben kontroll-, műtrágya-, valamint szalmakezelést alkalmaztunk, melyeket bizonyos kombinációkban három különböző baktériumkészítménnyel (Bactofil A, EM-1, Microbion UNC) egészítettünk ki. A kísérletet három ismétlésben véletlenblokk elrendezésben állítottuk be. A tesztnövény angolperje (Lolium perenneL.) volt. A kísérlet kezdetétől számított 8. héten a talaj-, valamint a növényminták begyűjtésére került sor. Meghatároztuk a növényminták száraztömegét, a növény foszfor- és káliumtartalmát, valamint a talajminták nitrát-, valamint AL-oldható foszfor- és káliumtartalmát. Eredményeink alapján főbb megállapításaink a következők: – Az angolperje száraztömegét a műtrágyakezelés szignifikánsan növelte. A hatás a tápelem-ellátottság javulásával magyarázható. – A növény foszforkoncentrációja a műtrágyázás következtében csökkent, amelyet a hígulási effektussal magyarázhatunk. – A növény káliumkoncentrációját a műtrágya-, valamint a műtrágya+baktériumtrágya kezelések szignifikánsan serkentették. – A talaj nitráttartalma szignifikánsan növekedett a műtrágyakezelés kivételével minden kezelésben. – A talaj AL-P2O5-tartalma az NPK-műtrágyázás és az EM-1 kezelés következtében statisztikailag igazolható mértékben megnövekedett, míg az AL-K2O-tartalom kizárólag a szalmakezelés hatására nőtt. A baktériumkészítmények önmagukban alkalmazva általában nem eredményeztek jelentős változást a vizsgált paraméterekben, azonban a készítmények szerves/ásványi anyagokkal kombinált adagolása esetében különböző mértékben befolyásolták a vizsgált mutatókat.
