Blueberry belongs to the Vaccinium Genus, Ericaceae Family, Ericales Order. The highbush blueberry (Vaccinium corymbosum L.) is classified as a commercially-grown berry. Blueberries are appreciated for their taste, nutritional value, and both pharmacological properties and biologically active functions. This study objective was to determine the total sugar content in frozen fruits of the highbush blueberry genotypes used as genitors ('Simultan', 'Delicia', 'Duke', 'Azur', 'Northblue', '4/6', '6/38') and 88 hybrid progenies 'Simultan x Duke', 'Simultan x Northblue', 'Azur x 6/38', 'Azur x 4/6', 'Delicia x Duke', 'Delicia x Northblue'. The total sugar content of frozen fruits was analyzed by the phenol-sulfuric acid method. The results showed that the total sugar content of the genitors varied between 2.83 and 3.81 g glucose/100 g. The fruits of 'Simultan' cv. had the highest total sugar content (3.81 g glucose/100 g). The highest total sugar content, 5.486 g glucose/100 g, was found in a 'Simultan × Duke' hybrids.

At the National Institute of Research and Development for Potato and Sugar Beet – Brasov, Romania field experiments were carried out in order to collect data on quantitative traits (plant height, number tubers, tuber size, tuber weight) and yield of some new potato genotypes. It was used a complet randomized block design with four replicates. The number of steams varied between 14.5 steams / hill on genotype 1947/2 and 5.5 steam / hill on genotypes 1979/5 and 1901/12. The lowest value of the median leaf length was recorded at clone 21-1901/7 (56 cm) and the highest at clone 1947/2 (181 cm). Brasovia variety (control) has a poorly developed root system (48 g), also the genotypes 1891/7, 21-1895/1, 21-1901/7. Instead, genotypes 1901/6, 1927/1, 1971/9, 1965/16 have a high weight of the root system. Most spectacular production was provided by the line 1979/5 (77.90 t/ha), followed by the lines 1901/7 (45.55 t/ha) and 1939/2 (47.93 t/ha). The lines 1895/4, 1876/7, 1971/9, 1927/1, 1968/2, 1897/2, 1968/1 and 1947/2 also recorded significantly high productions.

In this paper there were presented data about the invertebrates from the Bihor County, during 2021 – 2022. There were recorded 82 species belonging to 5 classes, 13 orders and 76 genera. There were obtained ecological data of these species, unknown in the scientific literature. The premature appearance of the species Pieris rapae L was observed about a month earlier then the period mentioned in the scientific literature. Many species in various stages of development have been observed to be active during the cold season, due to the relatively high temperatures recorded during this period, as a consequence of global warming. The recorded data contribute to the deepening of knowledge about the ecology and spread of these species at the national level, some species being probably mentioned for the first time in the fauna of Bihor County. Most of the species observed are relatively common nationally. In terms of geographical spread, most species are European, others have a wider distribution, being cosmopolitan.

In traditional paddy production, large water losses may occur due to drainage, evaporation and deep percolation (groundwater is highly polluted). In addition, while production costs increase, it also decreases in production areas. This study has been researched together with the usability of the drip irrigation method (DI) to reduce the global footprint of water in paddy production and its economic analysis. In the experiment, two irrigation intervals (2 and 4 days), four irrigation water levels (75, 100, 125 and 150% of cumulative Class A Pan values) and three different paddy genotypes (Baldo, Osmancik and Ronaldo) were investigated. In the research, irrigation water between 513-820 mm was applied to the treatments. Actual Evapotranspiration (ETa) values are 565-855 mm; The Crop Water Productivity (CWP) ranged from 0.84-1.35 kg ha-1 m-3 and the Irrigation Water Use Efficiency (IWUE) ranged between 0.95-1.49 kg ha-1 m-3. Economical water productivity (EWP) was calculated between 0.79-1.24 $ m-3 and the cost-benefit (B/C) ratio was calculated between 1.11-2.33. When the traditional cultivation method, the ponding method in the pan, is compared to the province, it has been determined that water savings are between 70-81%. Yield according to branches was measured as 4882-10305 kg ha-1. According to the results of the research, up to 29% yield increase was achieved under the condition of applying 150% of the cumulative evaporation every 2 days.
在传统的水稻生产中，由于排水、蒸发和深层渗透(地下水污染严重)，可能会造成大量的水分损失。此外，在生产成本增加的同时，生产区域的成本也在下降。本研究结合滴灌技术(DI)减少全球水稻生产水足迹的可行性及其经济分析进行了研究。试验采用2个灌溉间隔(2和4 d)、4个灌溉水位(累计A类Pan值的75、100、125和150%)和3种不同水稻基因型(Baldo、Osmancik和Ronaldo)进行研究。在试验中，灌溉水量为513 ~ 820 mm。实际蒸散发(ETa)值为565 ~ 855 mm;作物水分生产力(CWP)为0.84 ~ 1.35 kg ha-1 m-3，灌溉水分利用效率(IWUE)为0.95 ~ 1.49 kg ha-1 m-3。经济水生产力(EWP)在0.79 ~ 1.24 $ m-3之间，成本效益(B/C)比在1.11 ~ 2.33之间。当传统的栽培方法，即锅内蓄水法，与省内进行比较时，确定节水在70-81%之间。按枝产量测定为4882 ~ 10305 kg hm -1。研究结果表明，在每2 d施用150%累积蒸发量的条件下，产量可提高29%。

The livestock sector is an important component of agriculture that involves the breeding of various types of domestic animals. Although animal husbandry is a key activity in global food production, providing food for human society, income, jobs, nutrients, etc. it also has negative consequences, being the second largest polluter after the power industry. An important issue related to the livestock sector is manure produced by animals. The purpose of this paper is to understand the potential of organic manure nutrients as well as the negative effects they can have on the environment. In order to carry out the study, investigations were required regarding the calorific value and the elementary analysis (C, N, H, S, O) for five different types samples of manure from: poultry, sheep, cow, horse and pig. All types of manure have a moisture content of between 40-60% and can be used for composting. With manure we can produce biogas, but is necessary to know the correct way of managing manure in order not to lead to pollution
畜牧业是农业的一个重要组成部分，涉及饲养各种家畜。虽然畜牧业是全球粮食生产的关键活动，为人类社会提供食物、收入、就业、营养等，但它也有负面影响，是仅次于电力工业的第二大污染者。与畜牧业有关的一个重要问题是动物产生的粪便。本文的目的是了解有机肥营养物的潜力以及它们对环境的负面影响。为了开展这项研究，需要调查五种不同类型的粪便样品的热值和元素分析(C, N, H, S, O):来自家禽，羊，牛，马和猪。所有类型的粪便的水分含量在40-60%之间，可用于堆肥。我们可以用粪便产生沼气，但为了不导致污染，必须知道正确的管理粪便的方法

The present paper studied the influence of organic biostimulators and fertilizers, administrated in three applications between 70-75 BBCH, on growth and fruiting processes of three apple cultivars grown in five and six years high-density orchards at the Research Institute for Fruit Growing, Maracineni, Arges (southern part of Romania). During 2020-2021, the increase of the trunk cross-sectional area registered an average of 5.25 cm2 (0.02-21.19 cm2), and the fruit yield averaged 55.64 t/ha (0-166.98 t/ha). The mean values recorded for the fruit weight and pulp firmness, were 173.22 g (74.13-558.76) and 76.50 units Bareiss HPE-II-FFF (53.60-89.10), while the pH of the fruit juice and total soluble solids fluctuated around 3.55 (3.09-4.68) and 13.3 ⁰Brix (9.45-18.20). Foliar treatment with Cifamin BK (1.5 l/plant) significantly increased fruit yield by 49.5% compared to the untreated variant. Fruit weight increased in all three fertilization treatments on ´Decosta Jonagold de Coster´ and ´Red Braeburn´. Organic biostimulators and fertilizers improved pulp firmness on ´Golden Reinders Delicious´, juice pH on ´Decosta Jonagold de Coster´ and total soluble content on ´Red Braeburn´. The results of the study showed that, on the mineral nutrition background, Cifamin BK and Biohumus treatments in apple orchards improved fruit yield and quality.

Three field experiments were carried out at the experimental Station of Adrar, during three successive growing seasons 2013/2014 to 2015/2016. The aim of this study was to investigate the relationship between the water supply levels and phosphorus and potash applications. The experimental design was a split plot design with three replications. The main plots were five irrigation levels (50, 70, 90, 100 and 120% of reference evapotranspiration (ET0)), while the sub- plots contained four fertilization treatments: control (T0), K2O (T1), P2O5 (T2) and K2O + P2O5 (T3). The obtained yields were 5.64, 5.37 and 7.87 t ha-1, during the three consecutive seasons. They were significantly affected by phosphorus apply (P <0.01) during the all trial seasons. No significant effect of potash was observed during the first season. Its effects were significant (P <0.05) and highly significant (P <0.01) during the second and the third season respectively. Water treatment effects were significant on yield and almost all its yield components. The highest water efficiency was recorded when water apply was close to 100 % of MET and elements N P K are available.

Invasive plant species may cause not only several health problems, but also economic and environmental negative impacts – a gradual decrease of biodiversity and decline of soil fertility, issues that have recently come into the attention of several organizations including the research ones, in order to limit the spread of such species. The control methods of invasive species are often effective on the short term and include the probability of ecosystem imbalance over time, so that an efficient and sustainable management method that could add value to products or improve some industrial processes are strongly required. This study describes the potential of alien plants to maintain the quality of human life through different types of valorization, such as pharmaceutical, agriculture or food industry applications, energy production, paper technology and natural dyeing of various materials. Invasive plant species represent a global problem, accelerated by the current level of pollution and the rapidly-evolving society. Knowledge of chemical composition of different plant parts of invasive species, their potential for developing new products and their health effects will contribute to an efficient control, mechanical, chemical or biological, and an integrated management.

Ornamental trees are used worldwide in landscape design. Taxus baccata L. is an evergreen non-resinous tree, often with multiple trunks and spreading, pyramidal or rounded canopy. It can be propagated generatively and vegetatively. Nurseries mostly prefer to propagate them by vegetative way, because this type of method is quicker and the newly propagated plants inherit the genetics of the mother plants. In this study we have selected two varieties of Taxus baccata `Repandens` (TBR) and T. baccata `Fastigiata Aurea` (TBF), in which different length stem cuttings (5–10, 10–20, and 20–25 cm) were obtained and propagated in two different periods (May and July). From our results could be concluded that TBR rooting percentage increased at the collected cuttings in May and at 10–20 cm size. On the other hand, at TBF cuttings rooting percentage reported significant increases at 5–10 cm, also at the cuttings collected in May. In conclusion, our research suggests that Taxus baccata cuttings could obtain a higher rooting percentage when they are collected in May, moreover the length of the cuttings could be an influencing factor.
