The goal of this study was to see how a combination of Rhizobium inoculant, S, and Zn nutrients affected chickpea nodulation and yield (Cicer arientinum L.) at Gewane, northeastern Ethiopia. The experiment included 12 treatments arranged in factorial combination of levels of inoculation (Rhizobium inoculated, un-inoculated), three rates of S (0, 15, 30 kg Sulphur ha-1) and rates of Zn (0, 1.5 kg Zinc ha-1). The treatment becomes laid out in randomized complete block design with 3 replications. Analysis of variance showed that yield and yield associated parameters (main branches, number of pod, quantity of seed, hundred seed weight, grain and straw yield), crop phenology (days to 50% flowering and days to physiological maturity), nodulation scores (nodule amount, nodule volume, nodule dry weight, effective nodule and nodulation score), N and P uptake at both locations had been significantly affected by the treatments. The best (1775.5 kg ha-1) suggest rate of seed yield over locations changed into acquired from blended costs of rhizobium and 30 kg S ha-1 which led to 28 % (389 kg ha-1) growth over the control. Consequently, rhizobium inoculation with rate of 30 kg S ha-1is recommended for chickpea production on the experimental site.
本研究的目的是观察根瘤菌接种剂、S和Zn营养物质组合对埃塞俄比亚东北部Gewane鹰嘴豆结瘤和产量的影响。试验包括12个处理，按接种水平(接种根瘤菌和未接种根瘤菌)、3种硫含量(0、15、30 kg硫hm -1)和锌含量(0、1.5 kg锌hm -1)的因子组合安排。治疗采用随机完全区组设计，有3个重复。方差分析表明，各处理对两个地点的产量及产量相关参数(主枝、荚果数、种子数量、百粒重、籽粒和秸秆产量)、作物物候(开花至50%和生理成熟天数)、结瘤评分(结瘤数量、结瘤体积、结瘤干重、有效结瘤和结瘤评分)、氮磷吸收均有显著影响。最佳产量(1775.5 kg hm -1)表明，不同地区的种子产量由根瘤菌和30 kg S hm -1混合成本获得，比对照增加28% (389 kg hm -1)。因此，建议在试验区鹰嘴豆生产中接种30 kg S ha-1根瘤菌。

Agriculture is one of the key economic activities designed to provide food for a growing population. It is expected that 21st-century agriculture will try to reduce the number of fertilizers by using microorganisms, in this category arbuscular mycorrhizas representing a complex set of benefits for plants and ecosystem services. The aim of this paper is to identify the mycorrhizal structures present in the roots of Zea mays. The objectives of the research are: i) are mycorrhizae natively present in the corn root and have a constant presence from the first stages of plant development? and ii) what kind of colonization pattern is characteristic of these roots? Maize has prominent fasciculate roots, and due to its intense branching capacity provides increased biological support for the establishment of mycorrhizal symbionts. Within the fungal structures highlighted, the most prominent were arbuscules and vesicles. Arum-type arbuscules were mostly observed, Paris-type arbuscules being less common in this species. Vesicles have a low frequency in the root cortex. They are present only in the early stages of plant development. Vesicular-arbuscular mycorrhizae are present in the root of the Zea mays plant with a constant presence, without major fluctuations.

The research aimed the study of an invasive species that has recently appeared in our country, Corythucha ciliata Say (plane tiger or lacy plane bedbug) (Hemiptera, Tingidae). Knowing this pest is very important in order to control it, in order to keep the appearance of the parks pleasant and clean. The insect is an aggressive pest of plane trees (Platanus spp.), which harms their leaves, leading to premature defoliation. The aims of this research were: identifying and monitoring of Corythucha ciliata Say populations; observations on the host plants in the analyzed space; tracking the biological cycle of the species Corythucha ciliata Say and the extent of pest. Following research conducted in 2020-2021, the invasive species Corythucha ciliata Say, was identified in 4 locations in Transylvania, on two species of plane trees, Platanus occidentalis Linné and Platanus x acerifolia Willdenow. In the ecological conditions of Cluj-Napoca (Cluj County), the numerical density of the pest on the plane leaves was of maximum 30 adults/leaf and 63 larvae/leaf. Concerning the biological cycle, it was found that, in the temperate-continental climate of Cluj-Napoca, the species has 2 generations per year.

The roots of the plants are in contact with a substrate, and biotic and abiotic factors influence their functioning and development. The most known microorganisms associated with plant roots are soil fungi, which are adapted to the soil's living environment, called mycorrhizae. Arbuscular mycorrhizae are the most common of these associations. In agricultural ecosystems, the constant use of technologies has resulted in a progressive reduction of mycorrhizal diversity. Due to this phenomenon, soil presents a lower potential for the development of multi-level hyphal networks which implies reduced connections between all individuals of a single species. Mycorrhizas offer benefits for the host plant, including mineral nutrition, increased drought tolerance, and protection against pathogens. They play a significant role in acquiring the necessary nutrients (especially phosphorus and nitrogen) from soil to their host plants, as these nutrients may have low mobility in most soils. Plants take up phosphorus from soil indirectly through the hyphal network that can reach outside from the root depletion area. Mycorrhizal association increases the accumulation of nitrogen in the plant as a result of the competition of hyphae for the organic mineralized form of this element.

Net blotch disease caused by Pyrenophora teres is one of the most damaging fungal diseases of barley crop. This study screened comparatively the effectiveness of eleven fungicide products applied to malting barley (Hordeum vulgare L. conv. distichum Alef.) cultivar ‘Daciana’ in conditions from Transylvania. After fungicide treatment, the net blotch disease index decreased an average of 70.37-78.04% relative to untreated control. Fungicide application ensured an average of 28.66% grain yield increase, 7.51% thousand grains weight increase and 4.36% grain starch content increase relative to untreated control. Top performance was obtained by using products that contained demethylation inhibitors targeting sterol biosynthesis in combination with other active substances with a different mode of action particularly targeting mitochondrial respiration. It is a difficult task to achieve top performance on all dimensions: strict disease suppression, high quantity and quality grain yields. Preventing the occurrence of pathogen resistance to fungicide and minimizing negative effect on crop as well as remanence in the plant, are the main challenges for fungicide use and should receive further attention.

Phyllopertha horticola Linné (Coleoptera: Scarabaeidae) is one of the most common phytophagous beetles in Central Europe. In 2020 the blueberry growers from the Mărişel area reported the presence of a new beetle that attacked the fruit’s flowers and leaves. The species was identified at the University of Agricultural Sciences and Veterinary Medicine in Cluj-Napoca as the garden chafer. In the following year, the plants attacked by the garden beetle were monitored in the blueberry plantation in the Mărişel area. For monitoring the garden chafer, three rows of land were randomly selected in each plot with intervals of 20 plants per row. Each plant was analyzed individually and the number of adult beetles reported on the plant was noted. The observations were made between June and July 2021. In the Elliot variety, the share of plants reported with adults of Phyllopertha horticola Linné was between 50% and 60%, the average being 55%. Regarding the maximum number of adults/plant, it was between 6 specimens (raw 1) and 9 adults/plant (raw 2). In the Bluecrop variety, the share of plants with adults of the monitored species was between 10% and 45%, with an average per variety of 25%.

The economy of Kenya depends mainly on agriculture where smallholder farming has a significant role as it employs 65 percent of the work force and contributes 32 percent of Kenya’s GDP. However, the agricultural industry in Kenya is currently facing difficulties in low productivity. The rural areas have the largest concentration of poverty and food insecurity. Majority of the farming activities in Kenya are on small scale and the problems of these farmers are multifaceted including sub-divisions and small farm sizes, leading to diseconomies of scale and low productivity. The goal of this research was to develop and validate an E-agriculture Framework for Improving Agricultural Productivity among the Smallholder Farmers. Descriptive research design was used. The study was carried out in South Eastern Kenya. The target population comprised 224 meteorological staff, 421 agricultural extension officers, 208 ICT personnel and 3,833 farmers. Data was collected using self-administered questionnaires, observation and interviews and analyzed using SPSS. The study found that challenges faced farmers were cost, illiteracy and ICT skills among others. Further, the study established that farmers required specific information such as soil management, pest management etc., for mainly improving their productivity. The researcher proposed an e-agriculture framework for improving agricultural productivity through promoting innovative use of ICT tools to bridge the distance between the farmers and the research communities. The proposed e-framework could be used by government policy makers and stakeholders on ICT on agricultural services in other developing countries to implement policies that speeded up the use of ICT on agricultural information.

Soybean is one of the most important leguminous crops due to its high oil and protein content with a significant role in nutrition. Micronutrients for soybean growth and development are very important and foliar fertilization is used to overcome environmental stress and help soybean plants to fill their nutritive needs. The research was carried out in 2020 by the Soybean Breeding Laboratory from the Agricultural Research and Development Station in Turda, Romania. Foliar fertilization had both positive and negative effects for 1000-grain weight and yield however, quality traits do not seem to be influenced by applying supplement of microelements during the vegetation period. The research suggests that genotype is the determining factor in the efficiency of foliar fertilization. In this sense, the present experiment will continue to bring answers regarding the effects of foliar fertilizers on some soybean genotypes.

This study investigated the allelopathic effects of Medicago sativa L. on the germination characteristics of weed rye (Secale montanum L.) Guss. In order to study the allelopathic effects of different concentrations of aqueous extract (0, 10, 20 and 30%) of different M. sativa parts (root, leaves, stem and aerial parts of the plant including (stems, leaves and flowers) on initial growth of rye (S. montanum) seedlings a factorial experiment arranged in RCB design was carried out with three replications in the greenhouse of Agricultural College, Mahabad Islamic Azad University in 2017. The greenhouse data showed that the plant height, root and biomass dry weight of the weed decreased so that the declining trend had a significant effect (p≤0.05) on all traits of rye studied in the present experiment. Among the aqueous extracts of M. sativa that of the root had the greatest allelopathic potential.

The paper presents the results of research conducted during 2018-2019, regarding the root nodules formation at soybean, by applying different tillage systems, under the conditions of the Agricultural Research and Development Station Turda situated in the Transylvanian Plain.The development of root nodules in soybean differs from one variety to another, the highest value of 103 nodules/plant is recorded in the Onix variety and lower in the Cristina and Felix variety with 66 and 69 nodules respectively. Also at the weight of the nodules/plant it seems to maintain the same trend, the Onix variety (0.86 g) being superior to the other two varieties (Felix 0.83 g, Cristina 0.80 g). The highest soybean average yield was registered at the Cristina variety cultivated in the minimum tillage-chisel (2548 kg/ha) and the lowest yield at the Felix variety in the no tillage (1592 kg/ha).
