Researches regarding the production capacity and quality of alfalfa in crisurilor plain condition

Nitrogen supply through mineral fertilization affects nitrogen biological fixation process in legume plants, even though plants can directly absorb the mineral N. For species such as alfalfa, in addition to the inhibitory effect, mineral fertilization decreases the useful life of the crop and the quality of protein in the dry matter According to some authors there is a positive response in biomass production for N application only in excess of 100 kg ha-1 year. The aim of this paper is to find conditions resulting in higher production of alfalfa under different variants of fertilisation in Batar conditions, Bihor county and the chemical analysis of this forage. The research was carried out in the experimental fields that belong to the society SC Frevest SRL from Batăr locality, Bihor county, the experiment being placed on a chernozem argiloiluvial soil. The experimental setup was randomized block design, in three repetitions, the plot surface being 45 m2 . Sowing was made on October 5th 2010. In order to determine the production, the harvesting was done at 61st phenophase (beginning of flowering: 10% of flowers open) of alfalfa (the extended BBCH-scale, general). Considering the analyses regarding alfalfa production capacity the biggest production of green mass was obtained at N50P50K50+ N100 fertilization variant of 47.00 t ha-1. The differences are statistically assured as very significant and have been registered between alfalfa production obtained at variant N50P50K50 (25.7 t ha-1) and variant N50P50K50 + N50 (42.3 t ha-1); variant N50P50K50 (25.7 t ha-1) and variant N50P50K50 + N100 (47.0 t ha-1): variant N50P50K50 + N50 (42.3 t ha-1) and variant N50P50K50 + N100 (47.0 t ha-1). Regarding the chemical composition of the yield of N50P50K50+ N100 fertilization variant we can conclude: crude protein content is 178.7 g/kg, crude fiber content is 302.4 g/kg, NDF is 520.8 g/kg, ADF is 307.6 g/kg and ADL is 91.9 content on dry matter basis (kg DM)

Investigation regarding the production capacity of triticale under different variant of nitrogen

Some authors say that nitrogen supply through mineral fertilization affects nitrogen biological fixation process in legume plants, Triticale (xTriticosecale Wittmack), resulting from crossing between wheat and rye, has the potential to introduce valuable economic benefits to both grain and herbage production systems. Others say that triticale produces at least 20% more forage than wheat, and is higher in forage quality than rye or wheat and triticale has agronomic advantages, it can be grown on more marginal land (arid, acidic, etc.) and requires less agricultural chemicals (fertilizer, agronomic chemicals, etc.). For this triticale seems to be an interesting alternative to other cereals, particularly bread wheat, in environments where growing conditions are unfavorable or in low-input systems. The aim of this paper is to find the maximum production of triticale taking under different variant with chemical fertilisation in Batăr conditions, Bihor county and the chemical composition of this. The research was carried out in the experimental fields that belong to the society SC Frevest SRL from Batăr locality, Bihor county, the experience being placed on a chernozem argiloiluvial soil. The biggest production of triticale obtained in 2012, under different fertilisation variant was registered at N50P50K50 + N100 variant (5,4 t.ha -1 ), which shows us, that exist significant statistic differences between the production obtained at fertilisation variant N50P50K50 + N100 (5,4 t.ha-1 ) and the production obtained at fertilized variant N50P50K50 that have obtained 4,8 t.ha-1 . Regarding the chemical composition we can conclude that: the dry matter content is 88.56%, crude protein content is 134.41 g/kg, crude fiber content is 17.4 g/kg, NDF is 470.27 g/kg, ADF is 22.13 g/kg and ADL is 18.45 g/kg, content on 1000 g fresh matter
