Published: December 2021

The practice of sustanainable agriculture demands the best qualitative indexes for spraying machines and, especially, better distribution uniformity on the working width of these machines.
The experimental trials in laboratory conditions were made for EEP-600ME mounted spraying machine by using the HERBST testing equipment for measuring the cross-cut distribution uniformity, which showed the fact that the boom inclination angle has a great influence on distribution uniformity. Rise of boom inclination angle over 2° leads to decreasing of distribution uniformity. At boom inclination angle only by 5°, the variation coefficient of distribution uniformity is over 24%, value that exceeds the allowable limit by four times over.
In order to maintain the qualitative indexes in sloped areas there is a demand to use spraying machines that are equipped with devices for boom leveling.

Published: December 2021

The control of ice cream powder mixture production is carried out evaluating the ice cream liquid phase. The present study was conduced on ice cream and unfrozen liquid phase in order to indirectly evaluate the rheological properties by measuring the powder mixture. The calibration set was formed by samples with different percentage of thickeners, maintaining constant the concentration of the other remaining compounds. After the NIR acquisitions the powders were mixed with warm milk, blended and than settled in order to obtain the unfrozen liquid phase needed for the rheological measurements. For each recipe three batches were prepared. The flow curves were evaluated by using the Ostwald de Waele’s equation and the goodness of fit was evaluated by the R2, which was above 0.95. Predictive models of rheological parameters were set up by means of PLS regressions in order to predict the consistency coefficient (K) and the flow behavior index (n) from spectral acquisitions. High correlation of calibration was found for both parameters and NIR spectra obtaining R2 of 0.884 for K and 0.874 for n.
The good prediction of the models encourages applying them to reduce significantly the time of the powder mixing control during production.

Published: December 2021

The efficiency of the anti - erosion agricultural operations is one of the main objectives of the designers for machinery and soil working tools on slopes. Mathematical modelling that using a systemic approach of the phenomena and processes and realistic assumptions, allows the optimum constructive-functional parameters for soil working tools, in order to achieve a properly working with low energy consumption. Storage capacity of the sediment profiles achieved by ground shaping is properly estimated according to the geo - climatic conditions of the area.
Previous researches (Cardei, Cota, 2008) led to the establishment of a calculation model in this respect. The method of calculation for choosing the geometry of profiles is the application of the final investigations, in conditions to assure a satisfactory storage capacity of sediments and a minimum energy consumption for the soil working processes.

The preservation of the genetic variability at the crop plants is an important premise for a long durable agriculture. Romania still has an important genetic diversity at the crop plants. Unfortunately in Romania the risk of this diversity disappearance is very big due to the age of the seeds producers and the big surface of unused land.
During 2007-2009, at University of Agricultural Sciences and Veterinary Medicine (USAMV) from Cluj-Napoca a series of actions for collecting vegetable seeds, for description from agronomical, biological and biochemical point of view of authentic local varieties, for producing and preserving seeds in the Gene Bank of Suceava have been undertaken. Investigations were made in 26 counties of the country but the experimental fields were placed at USAMV Cluj-Napoca.
In this work paper are briefly presented the main characteristics of the local varieties of parsley (Petroselinum crispum, subsp. crispum). Among the 64 studied cultivars, 54 (85.7%) proved to be local varieties and among these 5.5% are used for leaves, 20.4% for roots and 74.1% have mixt destinations.

Preservation of genetic variability at crop plants is of maximum importance for sustainable agriculture. Local varieties of crop plants can hold some unique genes that encode important characteristics for the present and future of humanity’s nutrition: resistance at stress factors, biotic and abiotic, nutritional and therapeutic qualities, excellent sources of genes for improving varieties, and so on. Ex situ conservation of local varieties in gene banks is a measure designed to save them from extinction.
During 2007-2009, at UASMV Cluj-Napoca have been studied more than 400 cultivars of vegetables for their characterization, production and for conservation of their eeds in seed gene banks.
For carrot 84 cultivars from 21 counties of the country were collected, among these 38 proved to be authentic local varieties, which represents 45.2%.
This paper presents biochemical characteristics (dry matter, total carbohydrate and total carotenoid) and the resistance to preservation of the local varieties taken into study, in comparison with five homologated carrot varieties.
Regarding biochemical analysis, mean values are the following – dry matter: 12.7% at local varieties and 9.4% at homologated varieties; total carbohydrate: 6.3% at local varieties and 3.7% at homologated varieties; total carotenoid: 10% at local varieties, with a minimum of 1.9% and a maximum of 23.2 mg/100 g. Average degree of attack by E. carotovora was 7.2% at local varieties, and 8.3% at homologated varieties.
