The organic fertilizers’ application and the traditional use for long periods of time have influenced the rich plant diversity in Apuseni Mountains, Romania. The objective of this study was to identify the effect of manure’s application upon the plant diversity and productivity of Festuca rubra L. –Agrostis capillaris L. grasslands. The experimental field evaluated four variants (V1: control, V2: 10 t ha-1 manure, V3: 20 t ha-1 manure, V4: 30 t ha-1 manure). After ten years, important changes at the sward level were observed. The control’s phytocenosis is naturally represented by Festuca rubra L. - Agrostis capillaris L. grassland type. Then, following the application of organic fertilizers, Trisetum flavescens L. - Agrostis capillaris L. appeared. The large quantities of organic fertilizers produced a considerable limitation on plant diversity. The applied treatments do not produce any important improvement of the grassland types’ agronomic value. Taking account the influence of organic fertilizers upon the DM yield, plant diversity and agronomic value, it is considered that the treatment with 10 t ha -1 manure annually applied produces optimum changes and might be taken into consideration for the low-input systems in Apuseni Mountains

Over time, studies of the vegetation of natural grasslands have evolved from simple observations to rigorous research. Feed obtained from natural meadows without major technological imputations is mediocre in quality, and pastures in a rather advanced state of degradation. The main purpose of this paper is the ecological and fodder evaluation of the Festuca rubra type of grasslands in the Apuseni Mountains based on the floristic composition and the productivity of these grasslands. The experience was carried out in Ghetari village, Apuseni Mountains, which was located in 2001, following the method of randomized blocks with 4 experimental variants in 4 rehearsals. Each variant were fertilized with organic inputs using the same quantities each year. In the paper we use the results obtained after 15 years of experience. The application of organic fertilizers caused significant changes in the canopy causing changes in the dominance of the type of grassland. The livestock manure applied on the studied grassland has increases significant yield production at all variants of fertilization.In this paper it was shown on which species the productivity of the grassland increased from the control variant to the fertilized variant with the maximum dose. Regarding the analysis of the phytodiversity, this tells us if the number of species is reduced in all the treatments, 10 t/ha of manure leads to an increase in phytocoenosis equivalence and implicitly to the Shannon index.

An important part of efficient livestock production is ensuring the sufficient grass for hay and pasture. However, low soil nutrient levels often limit forage production. With good fertilizer management and soil fertility, the productivity of many hay and pasture fields can be greatly improved. Through good fertilizer management, the productivity of many hay and pasture fields can be significantly improved by Ross H. McKenzie (2005). The aim of this paper was the effect of fertilization with liquid fertilizer (UAN) the harvest of dry and floristic composition changing on natural grassland. The experiment whose results we present was placed in 2014 in the place in Baisoara Mountain village, Cluj County. Experience has been placed on the Festuca rubra and Agrostis capillaries - of grassland type. The natural grassland of Festuca rubra with Agrostis capillaries responded very well to mineral fertilizers with liquid fertilizer UAN. The floristic composition of natural grassland fertilized with liquid fertilizers based on nitrogen, it can be seen an increase the Gramineae families and an evidence downward trend from Fabaceae families.

Natural grasslands are significant resources for forage production, which is not exploited enough, mostly because of low production, as a result of bad grasslands management. The research has been carried out on the association Danthonietum calycinae to evaluate the effects of different nitrogen application rates (N20, N80 and N140) and lime (1 tha-1) on the floristic composition, soil microbes and dry matter yield. Botanic composition was strongly influenced by the treatments, especially by N applications. Nitrogen fertilisation led to significant increase of grass species in the association (from 57% to 82%), while higher rate of nitrogen caused a significant decrease of plants from other families (especially legumes). Application of low and medium rate of nitrogen positively effect on microbial abundant in soil, but the highest dose (140 kg N) reduced all microbial count, except fungi. Mineral nitrogen fertilisation had a favourable effect on dry matter yield in all treatments. The highest increase in dry matter yield relative to the control was in N140 treatments (6.66 t ha-1). Results indicated that optimal applications of nutrients for this association is application of PK and lime and 80 kg of nitrogen which enable high yield (6.38 t ha-1) in comparison with control (3.16 t ha-1) and preserving soil fertility and the environment at the same time.   ********* In press - Online First.

Phleum Pratense L

Wild ecotypes of Festuca rubra L. (four accessions), Poa pratensis L. (three accessions ) and Phleum pratense L. (three accessions) originating from Central Slovakia were investigated. Dry matter production, qualitative traits as well as mineral content were studied under identical soilclimatic conditions in a three-cut system. Yield potential of wild ecotypes of Festuca rubra L. coming from mountain regions was significantly lower (P < 0.01) when compared to Festuca rubra L. cultivar Levočská. In contrast, as a consequence of low variability, the dry matter yield of Phleum pratense L. wild ecotypes originating from higher altitudes was comparable to the dry matter yields of Festuca rubra L. cultivar Levočská. There were not noted any considerable differences found in the content of crude protein, fibre or mineral substances between the wild ecotypes and the cultivars. All accessions showed consistent patterns in seasonal distribution with the highest dry matter yield at the first cut and with the lowest one at the third cut. In general, concentration of crude protein and fibre did not vary considerably among cultivars and wild ecotypes at all species under uniform growing conditions.

An experiment was conducted twice concurrently at Vom in Plateau State Nigeria in 2011 to evaluate the effects of three animal based organic fertilizers and three rates of application on the growth, seed and herbage yields of Rhodes grass (Chloris gayana var. Callide). This study involved three types (poultry, rabbit and sheep dung) of animal fertilizer and three rates (0, 25 and 50 t ha-1) of application in a 3 x 3 factorial arrangement fitted into randomized complete block design and replicated three times. Animal fertilizers significantly (p < 0.05) increased growth, seed, fresh herbage and dry matter yields of Rhodes grass. Generally, fertilizers from poultry and rabbit were similar and better (p < 0.05) than that of sheep in the enhancement of the measured variables. At 6 weeks after fertilizer application (WAF), fresh herbage yield was in the range of 14.6 – 48.3 t ha-1 whereas dry matter yield ranged from 4.7 – 13.9 t ha-1 while seed yield was 1.8 – 2.3 t ha-1. At 12 WAF, rabbit fertilizer produced significantly higher values than sheep fertilizer by 21.2 % for sward height, 70.1 % for fresh herbage yield and 61.4 % for dry matter yield. The correlation coefficients among the measured variables were positive and highly significant. The highest correlation recorded (0.937**) was between fresh herbage and dry matter yields. The study indicated that application of either rabbit or poultry fertilizer can suitably enhance Rhodes grass growth for higher herbage and seed yields. The study also showed that 25 and 50 t ha-1 of animal fertilizers on Rhodes grass yielded similar results. With adequate fertilizer application, Rhodes grass can produce sufficient herbage to meet the nutritional requirement of several ruminant livestock. It is not economical to apply more than 25 t ha-1 of animal fertilizers to Rhodes grass if they contain more than 1.21 % of nitrogen.

Vegetative Organs

The dry matter and moisture contents of the aboveground vegetative organs and kernels of four maize hybrids were studied in Martonvásár at five harvest dates, with four replications per hybrid. The dry matter yield per hectare of the kernels and other plant organs were investigated in order to obtain data on the optimum date of harvest for the purposes of biogas and silage production.It was found that the dry mass of the aboveground vegetative organs, both individually and in total, did not increase after silking. During the last third of the ripening period, however, a significant reduction in the dry matter content was sometimes observed as a function of the length of the vegetation period. The data suggest that, with the exception of extreme weather conditions or an extremely long vegetation period, the maximum dry matter yield could be expected to range from 22–42%, depending on the vegetation period of the variety. The harvest date should be chosen to give a kernel moisture content of above 35% for biogas production and below 35% for silage production. In this phenophase most varieties mature when the stalks are still green, so it is unlikely that transport costs can be reduced by waiting for the vegetative mass to dry.
