INTELLIGENT MONITORING OF DISEASED PLANTS USING DRONES
Get PDFPlant diseases are one of the grand challenges that face the agriculture sector world-wide. In the United States, crop diseases cause losses of one-third of crop production annually. Despite the importance, crop disease diagnosis is challenging for limited-resources farmers if performed through optical observation of plant leaves` symptoms. Therefore, there is an urgent need for markedly improved detection, monitoring, and prediction of crop diseases to reduce crop agriculture losses. Advanced imaging technologies can detect such changes, and can, therefore, be used as noninvasive crop monitoring methods. Furthermore, novel methods of treatment precision application are required. Both sensing and actuation technologies can be mounted on equipment moving through fields (e.g., irrigation equipment), on (un)manned driving vehicles, and on small drones

REALIZATION OF THE TOPO-CADASTRAL WORKS NECESSARY FOR THE REGISTRATION OF A CADASTRAL SECTOR, BELONGING TO CĂTINA COMMUNE, CLUJ COUNTY IN SYSTEMATIC CADASTRE
Get PDFThe study presents the analysis of the documentation for the registration of a cadastral sector in the systematic cadastre, the method approached at national level in order to determine the land areas and their registration in the Land Register. GNSS Global Positioning Technology has been used in this work, using a Trimble R8 GPS receiver and measurements made by linking to the National GNSS Station Network. For the elaboration of the cadastral plan were analysed the documents provided by the owners and the City Hall of Catina village. It is found that there are 27 buildings that have not been previously registered in the Land Register. The necessary measurements have been made and the property limits are positioned according to the documentation. It is found that the process used is an efficient one because of the shorter production times, in correlation with the complexity of the surface. Also, overlaps between neighbours have been eliminated

EMPIRICAL APPROACH FOR ASSESSMENT OF SOIL ORGANIC CARBON LOSSES BY WATER EROSION ON CALCIC CHERNOZEM
Get PDFWater erosion and loss of soil organic matter cause significant damages on the national economy of the Republic of Bulgaria. For development of sustainable agricultural systems, it is necessary to predict the development of these two degradation processes in order to effectively control them. Many models and methods have been created for this aim. Two of ways for assessment of soil organic carbon losses by water erosion are the parametric and the empiric approaches. The parameter sediment enrichment ratio (ER) was determined for two crops, grown by four tillage systems (in six years experiment. Except the parametric method, an empirical equation was developed for assessment of organic carbon losses by the amount of soil eroded
INFLUENCE OF THE PRODUCT FURIA ON THE MORPHOLOGICAL CHARACTERISTICS OF PLANTS AND FRUITS OF LONG PEPPER GROWN IN SOLARIUM
Get PDFFuria is a product of plant origin, easily assimilated by cultivated plants. It is composed of organic nitrogen, organic carbon of plant origin, potassium oxide and fulvic acid. The experiment performed in a cold solarium had as objective the influence of this product on the main morphological characteristics of long pepper plants and fruits. The results obtained showed a positive influence of the product on the growth in height of pepper plants, the increase in fruit length and diameter and the increase in the average number of fruits per plant. The biofertilizer is accredited for use in organic horticulture
THE EFFECT OF ORGANIC, ORGANO-MINERAL, COMPLEX AND LEAF FERTILIZATIONS ON MAIZE IN THE TRANSYLVANIA REGION
Get PDFThe paper highlights the implementation of a soil fertilization system with ecological protection for maize crops in Transylvania in a climate favorable to maize cultivation in an area with high quality soils in terms of fertility and favorable for most cultivated agricultural and horticultural plants, maize being cultivated in this region on a considerable area. Along with the maize harvest, the export of mineral elements from the soil is very high, which determines the rapid impoverishment of the soil, being necessary a proper fertilization of the maize crop, in order to achieve quantitative and qualitative production of corn grains.The specific nutrient consumption of corn, according to different authors, varies between: 20-30 kg N; 8-14 kg P2O5; 20-30 kg K2O; 10-14 kg CaO and 3.5-4.5 kg MgO, to achieve a ton of corn grains, needing large amounts of nutrients, throughout the growing season, to achieve the expected production. In this context, the paper aims to review Cojocna area, located in Cluj County, in the Transylvanian Plain, an area that nature has endowed with invaluable gifts, which lends itself to sustainable and profitable conservative agriculture. Soils, mostly of the faeoziom type, specific to this region, exhibit a high humus content, are well structured and aerated, which in terms of fertility are considered very productive. As a result of recent climate change and the specificity of the cambic faeoziom soils, which in the B cambic (Bv) horizon formed by altering the basic parent material "in situ", presenting in the upper part, dark brown colors followed by yellowish brown colors due to the accumulation of clay, which in conditions of heavy and long rains, favors the accumulation and puddle of water on the soil surface, which leads to asphyxiation and death of young plants, with undesirable consequences on the maize crop in the area. In this sense, it is known that corn is a plant species that resists well to unfavorable climatic conditions and also, has beneficial effects on all soils by improving aeration and soil structuring conditions, due to the well developed root system. The purpose of this paper is dedicated to the development of organic, organo-mineral, complex mineral and foliar fertilizations of maize crops in an area with high favorability for maize from Transylvania
STRUCTURE AND EVOLUTION OF THE AVAILABILITY AND CONSUMPTION OF BEANS AT NATIONAL LEVEL, IN AN INTERNATIONAL CONTEXT (2011-2013)
Get PDFBeans, being rich in protein (23-25%) and carbohydrates (48-55%) is used in the form of grains or as a vegetable in the form of pods. The berries have a high content of digestible proteins and a high nutritional value, being used in a wide range of dishes. For a long time, it was called "meat of poor people" due to the high content of grains in very good quality proteins, rich in essential amino acids important for the human body (lysine, arginine, tryptophan, etc.). In the diet are used not only the ripe grains, but also the green pods, which also have a high nutritional value, being rich in proteins, sugars, vitamins, etc. Some peoples, such as the Japanese and Chinese, use in their diet not only green beans and pods, but also young shoots, which are eaten as a salad. From the point of view of the components of the balance sheet, its equitable nature is noteworthy. Imports predominate (57.77%), followed closely by production (43.72%). It can be concluded that the trade balance is clearly unfavorable
WORKING SPEED AND QUALITATIVE INDICES OF SOWING WORK
Get PDFThe sowing speed is a determining factor for the observance of the qualitative indices of the work in terms of the distance between nests in a row and the sowing depth. This aspect is sometimes ignored compared to other links in cultivation technologies due to external factors such as: weather conditions, long distances between the soils to be sown, lack of seed supply, etc. Most seeders, which have higher working rates, contain in the instructions for use data on the recommended working speeds for uniform sowing, and information on the maximum working speeds at sowing, which are often taken by the mechanic as a standard but sometimes users do not respect and exceed them, ignoring the real conditions in the field, respectively the quality of the germination bed, which influences the displacement of the aggregate with a negative effect on the sowing accuracy (distance between nests) or depth at sowing. Basically, the speeds that exceed the recommendations for a uniform sowing lead to nonuniformities horizontally and vertically . Horizontally on the distance between the nests, vertically on the working depth. Each of the two parameters in turn with a negative effect on the number of plants per surface unit
