THE INFLUENCE OF FOLIAR FERTILIZATION WITH HUMIC ACIDS ON THE PRODUCTION OF WHITE CABBAGE

The main purpose of the study was to test the effect of some fertilizers based on humic acids on autumn cabbage,Bucharest F1 in the ecological conditions of the South-West of Romania. The foliar products applied were formulated and obtained by ICPA Bucharest. The biological material was represented by the Bucharest F1 hybrid. The experience included three variants: V1-untreated, V2-foliar fertilization with Deceneu and V3 foliar fertilization with Humifert Plus. In order to achieve the proposed objectives, biometric determinations have been carried out on the eatable organs: height and diameter of the head, the shape index and the degree of stuffi,but also the quantity and quality of the cabbage production. Application of fertilizers led to increased production at the fertilized variants, significant differences were at the variant with the Deceneu product, 132.5 kg/ha and a good accumulation of ascorbic acid, 35.78 mg/100g fresh matter, when applying Humifert Plu

RESEARCH ON CLOVER CROP MIXED WITH PERENNIAL GRASS FORAGE IN THE CENTRAL AREA OF OLTENIA

In the central area of Oltenia, Trifolium pretense specie can be used as perennial legume mixed with Dactylis glomerata or Lolium hybridum for temporary meadow. Between these two experimeted mixtures the best results were obtained by Trifolium pratense and Lolium hybridum that realized 6.25 t/ha dry matter as an average value on three experimental years. The meadow including 80 % Dactylis glomerata + 20% Trifolium pratense without fertlization, lead to the lowest forrage yiled, while the yield obtained by the mixture 40 % Lolium hybridum + 60% Trifolium pratense was much higher

THE INCREASING OF FODDER YIELD IN THE CENTER PART OF OLTENIA FOR SUSTAINABLE DEVELOPMENT OF LIVESTOCK

The environmental conditions from experimental area (ARDS Simnic, Dolj, Romania) offers favorable conditions for temporary meadows that give increased yield of quality feed. The proper fertilizing schedule combined with a good management contributes to a long permanence of temporary pasture

THE EXPERIMENTAL RESULTS REGARDING THE INFLUENCE OF THE COMPOST AND OF THE AMENDAMENTS TO THE TEMPORARY MEADOWS FROM SCDA SIMNIC

Both the simple mixture of graminaceae and pulverize and the complex react very weel both to the organic fertilization and the chimical one with nitrogen.The amount of the crop obtained in the mictures with organic fertilization, with oxidat between 1,3 – 2,1 t/m d.s. at the simple mixture and 1,8 – 2,6 t/ha d.s. in the case of the complex mixture of nitrogen. The nitrogenous, too has substantially contributed to the encreasing of the crop, ensuaring a growth of over 3,6 t/ha d.s. (N120) at the simple mixture, respectively over 5,4 t/ha d.s. (N120) at the complex mixture

Quantitative spectroscopy of single molecule interaction times

Funding Information: Deutsche Forschungsgemeinschaft (421152132 (subproject C03)), EXC 2046 (MATH+Incubator project IN-B2).Single molecule fluorescence tracking provides information at nanometer-scale and millisecond-temporal resolution about the dynamics and interaction of individual molecules in a biological environment. While the dynamic behavior of isolated molecules can be characterized well, the quantitative insight is more limited when interactions between two indistinguishable molecules occur. We address this aspect by developing a theoretical foundation for a spectroscopy of interaction times, i.e., the inference of interaction from imaging data. A non-trivial crossover between a power law to an exponential behavior of the distribution of the interaction times is highlighted, together with the dependence of the exponential term upon the microscopic reaction affinity. Our approach is validated with simulated and experimental datasets.Publisher PDFPeer reviewe

RESEARCHING RESULTS ON THE FERTILIZER APPLYING ON SOWN PASTURES ON LUVISOIL FROM ARDS SIMNIC

The sown pastures that are made of valuable grasses and leguminous fodder species have a high productive potential which can only be capitalized byproper fertilization. The mineral fertilizers are applied on a large scale due to their easy absorbtion by plants because they are soluble and immediate effect. Thenitrogen fertilizers applied on several rates substantially contributes to theobtaining of high harvests of fodder of good quality ensuring a better rescheduling of production

RESEARCHES ON THE APPLYING TIME OF FERTILIZERS AND THEIR TYPE ON SOWN PASTURES FROM CENTRAL AREA OF OLTENIA

Proper use of fertilizers on pastures assumes the detailed knowing of technical aspects related with the type of the fertilizer, the combination, the rate, the splitting, the time of applying, all these things making the object of extensive researches. Regarding the chemical fertilization, on sown pastures there can be used, both, simple fertilizers (ammonium nitrate, nitrocalcar, superphosphate, potassium salt, etc.) and complex ones in different formulas

A public dataset of 24-H multi-levels psycho-physiological responses in young healthy adults

Wearable devices now make it possible to record large quantities of physiological data, which can be used to obtain a clearer view of a person’s health status and behavior. However, to the best of our knowledge, there are no open datasets in the literature that provide psycho-physiological data. The Multilevel Monitoring of Activity and Sleep in Healthy people (MMASH) dataset presented in this paper provides 24 h of continuous psycho-physiological data, that is, inter-beat intervals data, heart rate data, wrist accelerometry data, sleep quality index, physical activity (i.e., number of steps per second), psychological characteristics (e.g., anxiety status, stressful events, and emotion declaration), and sleep hormone levels for 22 participants. The MMASH dataset will enable the investigation of possible relationships between the physical and psychological characteristics of people in daily life. Data were validated through different analyses that showed their compatibility with the literature

USE OF LIQUID FERTILIZERS BASED ON HUMATES EXTRACTED FROM LIGNITE IN WASTE DUMPS RECULTIVATION

Four liquid fertilizers based on humates obtained from lignite were developed and tested. The fertilizers were applied on the waste dump resulted from lignite open cast covered with fertile soil, at maize and alfalfa crops. The application of liquid fertilizers based on humates led to very significant increase of maize grain and alfalfa yields. The production reached the level of yields obtained in the area on land that was not affected by mining activities. The alfalfa plants concentration of macro elements and micro elements belongs to the ”normal” domain. The maize leaves had scarce nitrogen, potassium, copper, iron, and manganese contents and normal phosphorus and zinc contents

EVOLUTION OF SOIL ATTRIBUTES IN CONSERVATIVE AGRICULTURE

Results are presented obtained in an experiment carried out in conservative agriculture system in which chemical fertilizers assortments were tested in N, NP, NPK, and NPK with potassium humates matrix. Doses of 0; 50; 100; 150; and 200 kg N/ha were applied. The experiment was placed on a Haplic Phaeozem[1] at SCDA Teleorman and the test plant was soya. The evolution of soil physical and chemical characteristics was aimed at. Soil samples were collected on the 0-20 cm depth. It was ascertained that soil works in conservative agriculture system didn’t lead to changes in the total cation exchange capacity, exchangeable bases sum, and base saturation degree. The latter had a decreasing tendency,  from 88.6-90.6% to 85.8-88.5%, but not statistically ensured. Mobile forms of phosphorus and potassium had very significant increases in the variants treated with NP, NPK matrix fertilizers. Total forms remained constant.
