Implementation of Aerial Monitoring Technology in Permanent Grassland Management

In the last decade, in Romania, the management of large and very diverse agricultural areas from the point of view of the relief has been imposed especially the for the case of permanent grasslands. These ecosystems that are in balance due to the interdependence between the biotic and abiotic factors should be exploited according to correct management practices, supervised so that their level of production and quality should not be damaged. With the help of computer systems, the management and exploitation plan was established for 10-year periods corresponding to the period of renting these areas to livestock breeders. The present study aims at using the aerial monitoring with drone systems, the aerial surveillance of the correct implementation of management practices contractually assumed by the users and the breeders respectively. Thus, it is analyzed the quadratic processing of the surfaces, the compliance with the limits of rented areas, the observance of the load with animals per hectare (livestock unit LU) as well as of other management elements imported for maintaining and improving the condition of the permanent grasslands of Romania

Floristički sastav i kvalitet zemljišta Na prirodnim travnjacima Vojvodine

Ten specific locations (Aradac, Titel, Novi Sad, Krnješevci, Melenci - two locations, Deliblato, Bela crkva, Kumane and Novo Miloševo) on permanent grasslands of Vojvodina province were selected over the period of two years (2005, 2006). The soil and floristic analyses conducted in the locations of Movo Miloševo and Kumane indicated that cultural practices wouldn't be sufficient and that more serious practices would be needed. Regarding soil chemical composition, pH value vary from slight acid to slight alcal, except the locality of Aradac where reaction is acid. In all determinated locations nitrogen and potasium content is high, while phosphorus vary from low to high. Localities differ in floristical composition and thus in capability in animal nutrition. By applying cultural practices it is possible to increase forage yield and quality on determinated location. All locations were marked using GPS. Also, measures were taken to help the grasslands overwintering and to facilitate the action of fertilization treatments in the spring of 2007.U toku dvogodišnjeg perioda (2005/2006) određeno je deset specifičnih divergentnih lokaliteta (Aradac, Titel, okolina Novog Sada, Krnješevci Melenci - dva lokaliteta, Deliblato, Bela Crkva, Kumane i Novo Miloševo) na prirodnim travnjacima Vojvodine. Na navedenim lokalitetima utvrđen je hemijski sastav zemljišta i floristički sastav, odnosno kvalitet prirodnih travnjaka. Svi determinisani lokaliteti su obeleženi i locirani uz pomoć GPS metode. U pogledu hemijskog sastava zemljišta, pH vrednost varira od blago kisele do blago alkalne, izuzev lokaliteta Aradac na kome je utvrđena kisela reakcija zemljišnog rastvora. Na svim lokalitetima je utvrđen visok sadržaj azota i kalijuma, dok sadržaj fosfora u zemljištu varira od niskog do visokog. Ispitivani lokaliteti se razlikuju u pogledu florističkog sastava odnosno kvaliteta travnjaka, pa time i podobnosti za ishranu domaćih životinja. Na svim lokalitetima moguće je povećati prinos i kvalitet travnjaka primenom određenih agrotehničkih mera, pre svega drljanjem i đubrenjem. U tom smislu primenjene su adekvatne mere za tzv. prezimljavanje travnjaka, u cilju efikasnijeg sprovođenja i delovanja tretmana (drljanje i đubrenje) u proleće naredne godine (2007)

A Case Study of Consumer’s Attitudes towards Agro-Food Markets in Danube Microregion in COVID-19 Pandemic

The COVID-19 pandemic affected many aspects of human life including consumer behavior. The main aim of this paper was to identify basic patterns of changes in consumer attitudes towards agri-food products under the influence of the 2020 pandemic and to better understand to what extent and what kind of food market problems appeared for the inhabitants of the Danube microregion. For this purpose, an explorative study was elaborated. Assuming that the experience of COVID-19 affected consumer attitudes and sense of food security, a hybrid survey was conducted in the Danube microregion (Croatia, Serbia and Romania) during 2022. Data collected from a total of 903 respondents were statistically analyzed in SPSS. Descriptive statistics, PCA, ANOVA and t-Test were employed. The main results have shown that although the surveyed population of the Danube microregion during the pandemic in 2020 was generally not afraid of food shortages, food was in most part available for their families and their shopping habits have not changed to a large degree, the experience of the pandemic has raised the level of awareness about some issues related to food and specifically the prices of food products. Also, three different patterns of attitude and behavior towards food and agriculture, which emerged as a result of the experience of the pandemic in 2020, were identified. These patterns also proved to be different for different segments of the population. The findings suggest the need for stronger support for the development of locally affordable food systems with the use of ICT as a coping mechanism in crises

Effect of salinity stress on ion accumulation and on the photosynthetic activity of a new energy plant, phalaris arundinacea cultivars

Reed canarygrass (Phalaris arundinacea) is a good candidate for bioenergy production in Northern and Middle Europe. The crop is well-adapted to cold and drought stress but its resistance to high salinity has not been revealed in details. In this study the effects of 75 and 150 mM NaCl treatments were investigated on the ion accumulation, water potential changes and photosynthetic activity of three Romanian reed canarygrass genotypes, Tardin, Romanesti diverse and Timpuriu. Since cv. Tardin was able to maintain high K+ level and relatively low Na+ concentration in leaf tissues, high stomatal conductance and net CO2 fixation rate under salt stress and as it could maintain the water potential of tissues at control level, this genotype can be defined as salt tolerant. Salt stress induced significant Na+ accumulation, very low K /Na+ ratio, and severe reduction in stomatal conductance and photosynthetic activity in the leaf tissues of Timpuriu cultivar, which proved to be sensitive to high salinity

The relationship between humour types, assertiveness, self-efficacy, personality, and perfectionism in pre-service teachers

Teachers’ humour has a special place in the educational context with multiple benefits for themselves and their students. As a complex concept, humour is strongly related to individual personality, which is also complex and diverse. The current research aimed to investigate the correlations between four types of humour (affiliative, self-enhancing, aggressive, and self-defeating) and assertiveness, perfectionism, and Big Five personality traits (openness, conscientiousness, extraversion, agreeableness, and emotional stability) in pre-service teachers. The obtained results show that the adaptive type of humour (affiliative and self-enhancing) positively correlated with assertiveness, Big Five personality traits, and the adaptive form of perfectionism, and negatively with the maladaptive form of perfectionism. Also, the maladaptive type of humour (aggressive and self-defeating) negatively correlated with assertiveness, Big Five personality traits, and positively with the maladaptive form of perfectionism. An intriguing finding was the positive correlation between aggressive humour and assertiveness
