EFFECT OF ECOLOGICAL PRODUCT CARBECOL AND BIOFERTILIZER ECOLIT ON MANAGEMENT OF LATE BLIGHT (PHYTOPTHORA INFESTANS) AND PRODUCTIVITY OF TOMATO (SOLANUM ESCULENTUM) PLANTS

Organic agriculture is gaining importance and the market for organic products has been significantly increasing nowadays. Different diseases affect tomato especially the pathogen Phytophtora infestans, which is a major threat in organic and durable agriculture. A greenhouse experiment was carried out to evaluate the effect of new biorational protection product Carbecol and humic substances Ecolit in late blight management in tomato and their impact on the productivity. Tomato plants during vegetation period were treated four times with Carbecol in dose 6 kg/ha alone as well as in combination with application of biofertilizer Ecolit in doze 3L/ha. Control were untreated plants. Experimental results revealed that foliar diseases like late blight of tomato were significantly reduced by treatments applied either alone or in combinations compared to untreated plants. However, the best results were obtained in variant with integrated application of Carbecol, Ecolit plus ecological protection product Funecol in concentration 0,4%. The treatments had beneficial impact on fruits productivity of tomato. Experimental results demonstrated that application of Carbecol alone did not significantly increase the yield. However, the integrated use of Carbecol, humic substances Ecolit and Funecol gave better effect and the yield increased by 15,7% compared to untreated plants. Hence, experimental data suggests that the combined application of Carbecol, Ecolit and ecological fungicide Funecol could reduce the incidence of Phytophtora disease and increase tomato productivity. The integrated application of these ecological products of plant protection and biofertilizer could be an option for development of durable agriculture

GENETIC AND CHEMICAL APPROACHES TO MANAGE RYE LEAF RUST (PUCCINIA RECONDITA F.SP. SECALIS) IN NATURAL CONDITIONS FROM MARGINAL AREAS

Pathogens and pests are predicted to spread to areas where they were previously irrelevant due to climate change and human-induced changes, posing new management issues for crops, especially in cropping systems based on minimal cereal crop diversification. In temperate areas of Central and Eastern Europe, rye (Secale cereale) is a minor cereal that contributes to crops diversification particularly in marginal situations where soil and climate are unfavorable for wheat production. During 2021-2022 growing season, a plant–pest-pathogen interaction profile was observed on four rye genotypes (Binnto, Inspector, Serafino, Suceveana) and also was observed the effect of different chemical and biological pesticide formulations on rye leaf rust in a randomized complete block design with three replications in dry area from Research and Development Station for Plant Culture on Sands Dăbuleni in South of Romania. Among all evaluated rye genotypes the greatest resistance was noticed in Serafino that recorded the lowest AUDPC value (51,76), while the most susceptible was Suceveana genotype with AUDPC = 279,55.  The best protection against leaf rust was provided by Poliversum (the 1st assessment – attack degree = 3,23%; the 2nd assessment – attack degree = 7,56%). Negative and significant correlation of leaf rust attack degrees with grain yield (r =-0,9393***) were found during 2021-2022 cropping season

PRELIMINARY DATA REGARDING THE SAPROXYLIC SPECIES OF CERAMBYCIDAE (INSECTA: COLEOPTERA) IN ROSCI0045 CORIDORUL JIULUI, ROMANIA

Observations carried out in May-September 2022 in CoridorulJiului, a Natura 2000 area located in the south-western part of Romania, highlighted 16 species of Cerambycidae beetles. The landscape, local climate and forest management impact the diversity and distribution of these species in the site. All species have been listed on The IUCN Red List of Threatened Species, of which, Cerambyx cerdo, Rosalia alpina and Morimus asper funereus are also included in the Natura 2000 network. Five species were recorded for the first time in this area. Furthermore, another species noted, Isotomus speciosus, is a rare species in many European countries. The saproxylic character of these beetles makes them an essential participant within the forest ecosystem, which is why a responsible management of the forests in the Coridorul Jiului area is necessary to maintain the populations of these coleopterans on a stable trend

EFFECT OF EARLY BERRY THINNING AND GIRDLING ON GRAPE QUALITY OF CV. VICTORIA

The research was carried out at University of Belgrade Faculty of Agriculture experimental station “Radmilovac” on table grape Victoria cv with aim to improve grape quality and with consideration the introduction of these ampelographic measures in regular grapevine growing. The research included two treatments of berry thinning (thinning bunch tip - BtT and first lateral wink -BtW), girdling (G) and control (C). Combined effect of berry thinning and girdling were not examined. The following features were examined: fertility and yield, bunch and berry dimensions, bunch and berry structure, sugar content and total acidity. The thinning treatments did not have significant effect on uvometric parameters and grape quality, but they improved the yield by 41.7% (BtW) and 51.4% (BtT) in comparison to the control. It can be explained by bad fruit set influenced by unfavourable meteorological conditions during flowering in control treatment. Berry thinning achieves a better fruit set. Berry thinning should be applied as a regular ampelographic measure according to weather conditions during flowering phonological stage. Results confirm the positive influence of girdling. The yield was increased by 88,34% compared to control, berries had a higher diameter (for about 1mm with respect to control), fruit set and bunch mass were in higher level against other treatments, sugar content (17,00%), total acidity (5,75 g/L) were improved too. Girdling can be introduced as a regular ampelographic measure in the table cultivars vineyards, in order to obtain higher yields and better quality of table grape

ANALYSIS OF FOOD ADDITIVES IN THE PRODUCTION OF SAUSAGES

Portulaca oleracea L., considered by many a weed, is in fact a plant with multiple food and medicinal  values, and with a specific adaptation to stress conditions. Grown in water supply option conditions, the plant has a C4 type metabolism, but in drought conditions, it uses the way of closing the stomata during the day, achieving a CAM type metabolism. The high values ​​of the stomatal conductance recorded in the dark and the high contentof malic acid in the leaves especially in the morning, indicate this adaptation.Plants exposed to water stress also showed higher values ​​of suction force and higher percentages of bound water

RESEARCH ON THE MODIFICATION OF THE BAKING PROPERTIES DURING THE FLOUR MATURATION TIME

Wheat is one of the most important food plants grown in over 45 countries, feeding 35-40% of the world's population. The main utility is manufacturing bread and various products made from flour. Bread is the basic food for the majority of the world's population. No other food satisfies the needs of the human body as completely and economically as wheat bread. The most complete and perfect food is bread, which is obtained from flour of wheat. Through this study, it was followed how the different properties of bakery of white flour type 650 alter during the maturation period for 30 days. The analysed properties were studied on 3 batches of type 650 flour obtained in February 2022. Type 650 white flour was studied because it is the most used flour in the bakery industry and the consumption of white bread is approximately 65% ​​compared to the others bread assortments. On the flour samples obtained by grinding, the following parameters were monitored at intervals of 10, 20 and 30 days: moisture content, wet gluten content, hydration capacity, dough development time, dough stability. For all three flour samples taken in the study, it is observed that the capacity of flour hydration increases during storage by 1.4 units in batch 3, by 1.8 units in batch 2 and by 2 units to batch 3, the development time of the flour, determined for the three batches of type 650 flour, registers a decrease, which varies between 0.4 in lot 2 and 3, and 0.9 in lot 1; and as for the stability of the dough, there is an increase that signifies the time the dough maintains its maximum consistency, which indicates the dough's tolerance for kneading. The gluten content and the moisture content during the storage period decrease in all 3 flour samples
