Within the paper the results of conducted researches in order to obtain a protein hydrolysate from wool waste as raw material are presented. The experiments were conducted in two variants: a) alkaline hydrolyse using potassium hydroxide, a mix of potassium hydroxide with urea and a mix of potassium hydroxide with sodium hydroxide as well as b) acidic hydrolyse with sulfuric acid or a mix of sufuric acid with phosphoric acid in different proportions. The parameters intervals used were: pH 0,5-2,5 for acidic hydrolyse and pH 9,5-13,5 for the alkalinic one; temperatures between 120-150 °C and pressures between 1,4-4,6 bar. Acid hydrolysis is favored by the high proportion of sulfuric acid, phosphoric acid, a low pH and from high temperature and pressure. The alkaline hydrolysis is favored by a pH higher then 12 as well as the urea content. A high temperature and pressure has a beneficial effect over alkaline hydrolysis.

In this study our goal was to analysis the influence of different concentrations of lead on the process of water accumulation in the roots and stems of bean seedlings. In the experiments, the Borlotti variety are used. The seeds (100) were soaked in the corresponding lead acetate solutions: V1 – distilled water; V2 - 0.001%; V3 – 0.005%; V4 – 0.01% and V5 – 0.1%. and were put in germinators. The roots and stems of 10 seedlings of each experimental variant were used for determining the quantity of humid and dried substance. The control had high quantity of humid substance, which proves that the water contained in the vegetal material was important for the growth of these organs. The most significant decrease was recorded at concentrations above 0.1%, being highly inhibited.

Soybean is currently one of the most important agricultural crops being used in human and animal nutrition, as a raw material for industry but also has agro-phyto-technical importance because it contributes to the raising of soil fertility by fixing atmospheric nitrogen by symbiosis between soybeans and Rhizobium japonicum bacteria, which forms root-nodules. To achieve the aims, a poly-factorial experience has been placed during the period 2015-2017 at ARDS Turda, with the factors: Factor A - the tillage system (a1 the classical tillage system by plowing with the return of the furrow and a2 the minimum tillage system, chisel variant; factor B- the fertilization (b1-N20P20K0 100 kg/ha, applied simultaneously with sowing, b2-N20P20K0 100 kg/ha, applied simultaneously with the sowing + N20P20K0 100 kg/ha, applied in the 4-6 leaves phenophase, b3-N20P20K0 100 kg/ha applied simultaneously with sowing + N30 100 kg/ha, applied in the 4-6 leaves phenophase and b4-N20P20K0 100 kg/ha applied simultaneously with sowing + N20 100 kg/ha, applied in the 4-6 leaves phenophase, factor C-climatic conditions in the experimental years (c1-2015; c2-2016; c3-2017). The soybean variety studied was Malina TD. Following the application of the minimum tillage system, the yield decreases with a significant difference of 86 kg/ha compared to the conventional tillage system. A very significant influence in the yield of superior quantitative yields is fertilization, in the three variants where the supplementary fertilization was applied, there were obtained very significant yield increases of over 199 kg/ha compared to the control variant which produced a yield of 2373 kg/ha.

The aim of this research was to identify the ecological factors which have influences on distribution, development and habitat suitability of the summer truffle (Tuber aestivum) in the Sub-Carpathian region of Transylvania. The ecological factors such as average annual temperature (°C), average annual precipitation (mm/year), the length of the bioactive period (months), land slope (grade), slope orientation, soil pH and its compaction level were analyzed having specific influences on forest vegetation development in Sub-Carpathian hills, and in the same time on the possibility of symbiosis existence between the trees and summer truffle. The most favorable regions from the Sub-Carpathians of Transylvania for summer truffle growth proved to be Dealurile Năsăudului and Homoroadelor Sub-Carpathians followed by Muscelele Năsăudului and hills of Bistrița, where the average annual temperature is between 6,8-11°C with an average annual precipitation of 900 mm/year, a 3-6 months long bioactive period and high humus content of the soil.

During June, 2017, ten products from the food bases category have been studied. The companies and the products types were noted and the manufacturer’s labels were studied. It has been found that the rules on the labeling of food bases are respected. The study had the following objectives: studying the ingredients and the nutritional composition and identifying the additives used in the manufacture of the product. Studying product labels also highlighted an increased salt and sugar content. The percentage of dehydrated vegetables was between 4.49% and 38%. The vegetables content was different for the food bases investigated. The 40% of food bases had between nine and ten dehydrated vegetables, the 60% had between four and six dehydrated vegetables. Additives added to foods during processing are important to improve their appearance and to extend their shelf life.

Prunus cerasus L. are an allotetraploid species from temperate climatic zone. The aim of this study was to characterize some native sour cherry genotypes from different orchards from Romania, based on RAPD markers. We used 14 primers RAPD to analyze a total of 14 varieties of sour cherries. After analysis, a good level of polymorphism was generated about only six primers (OPA 04, OPB10, OPA17, OPA20, OPA03 and OPB17) the rest of primers were considered monomorphic. The dendrograme separated the cultivars according to their genetic and geographic origin. The genetic similarity among the cultivars showed a good diversity between the genotypes, so we can suggest that our native cultivars of sour cherry can be considered as distinct genotypes for futures breeding programs and new cultivar identification. Results also confirm that the RAPD primers can be used for genetic studies and to evaluate the varieties for breeding programs.

To determine the evolution soil fertility as a result of NPK fertilization, are presented experimental results from a long-term experience after 44 years of fertilization. The experimental field is located on the chernozem - soil type, the plant of culture was wheat. Nitrogen and phosphorus doses that were applied had 2 graduations. We tracked the influence of fertilizers on the production and content of nitrogen, phosphorus, potassium, humus, pH and heavy metals: Cu, Cd, Pb and Zn from the soil after harvesting. The highest yield (4288 kg / ha) was obtained in fertilized variants with N100K150, variants where the production level increased by 216% compared to the unfertilized soil (1987 kg / ha); Fertilization with 100 kg / ha of phosphorus alone or with 50-150 kg / ha of potassium and fertilization with N100P100 along with doses of 50-150 kg / ha of potassium have led to very significant increases in the level of the mobile phosphorus in soil (from 34 mg / kg in unfertilized soil to 178 mg / kg in variant fertilized with N100P100 kg / ha), the potassium content of the soil increased very significantly with the increase of the applied potassium dose.

Mineral and organic fertilization have a huge effect on natural grasslands. The purpose of this research is to assess the state of the biodiversity and pastoral value for grasslands from the Transylvanian Plateau area. In this area has been analyzed the floristic composition and a series of ecological indexes, respectively humidity, soil reaction, temperature and nitrogen. Other aspects taken in account were the agronomical and anthropogenic specters. The analyzed grasslands are placed in the perimeter of Gheorgheni village, from Cluj County. Experience includes 20 experimental variants with organic fertilization with combined with mineral fertilization, 5 variants in 4 rehearsals. Each experimental variant is 2 m long X 5 m wide. In most hill meadows the economic efficiency is relatively low, and in order to be increased, it is necessary to apply the whole complex of measures for their improvement, care and exploitation, of which a special role is the application of appropriate treatments that stimulate the development of valuable species. Several researches show that applying fertilizers on grasslands is economically justified since, generally, 1 kg of active element results in an increase of 80-100 kg of green matter.
