The Role of the 4M-ECO Agrieconomical Modell in the Crop Cultivation
Published May 4, 2004
170-173

Today, c for agricultural use are of ever increasing significance. These provide an opportunity for more accurate planning, and favourably influence the efficiency and economic performance of given enterprise. The relevant literature divides models according to various criteria. The most common is the division between optimising and non-optimis...ing models. Non-optimising models generally endeavour to make the best use of technological lines, machine capacity, while optimising models are used to optimise revenue returns from sales or, occasionally, production costs. In our case, revenue and returns from sales were optimised. The models examined consist of several modules. Which include the following: plant cultivation modules, evaluations (assessment of situation, conception plan, complex corporate evaluation), supplementary sheets (sheets and charts for ancillary plant production, general costs of operation, summary and crops structure optimisation). With the help of the model, annual a particular can be made for an optimal crop structure the resources of the enterprise. This it becomes possible to define the largest net revenue on a corporate level.

Investigation of the production parameters, nutrient and mineral composition of mealworm (Tenebrio molitor) larvae grown on different substrates
Published May 26, 2022
129-133

During the rearing of mealworm (Tenebrio molitor) larvae, the optimisation of the growing substrate has a particular importance. The application of the appropriate substrate is a fundamental pillar for intensive and safe production. The requirements for substrate include the lack of toxins, high nutrient and micro-macro element content. The... aim of this study was the evaluation of the effects of different substrates on the production parameters, nutrient and mineral composition of the mealworm larvae. The experiment lasted through 14 days. 5 treatments were set up at, where the variable was the substrate. The test system consisted of 25 units (5 treatments and 5 replicates). 10 mealworm larvae per unit, (total of 250 larvae) were used at the beginning of the experiment. Regarding the substrates, our study included sweet potato (SP), may turnip tuber (MT) and may turnip leaf (ML). In addition to the plant by-products, wheat flour (WF) and wheat semolina (WS) were used as control substrates. Trace element uptake and production parameters of the larvae were determined at the end of the experiment. Regarding the production parameters, it can be stated that the wheat semolina (0.081 ± 0.005 g) and wheat flour (0.069 ± 0.007 g) substrate used as control gave the best results for the final body weight. In terms of plant raw materials and by-products, sweet potatoes (0.063 ± 0.007) can only be recommended as substrate, while may turnip tuber and may turnip leaf produced significantly lower final body weight results (MT=0.034 ± 0.002 g ; ML= 0.036 ± 0.002 g). The nutrient composition of the larvae was not affected by the substrate, these results confirmed the high protein and fat content reported in the literature. The results with the production parameters were contradicted by the micronutrient content. Larvae reared on may turnip leaf (ML) and tuber (MT) showed the highest values for most of the macro- and microelements (potassium, calcium, magnesium, iron, zinc, copper) tested.

Optimising intensive apple crown pruning by IT improvements
Published September 5, 2018
165-173

Prunig is a key element of fruit production technology and is affected by a number of subjective factors. Putting research findings into practice is often hindered by bad and harmful habits that make plantations and trees heterogenious in terms of growth and fruiting features, which can even lead to significant financial losses. Having identifi...ed this challenge, in this publication we aim to present some guidelines for those who are open to new ways and believe in the power of innovation. The 21st century is undoubtedly the century of unstoppable IT innovations filtering through into our everyday lives. The fact that our project is based on IT innovations is not only essential due to the subject matter itself but also because it makes it easier to address younger generations. Whichever tool they choose to use (smartphone, tablet, laptop), all registered students have access to our web contents, making it super easy for them to practice pruning techniques. Students don’t just read texts in our training materials but have access to a pool of pictures and images to illustrate the different procecces and phenomena. All the different phrases have explanations against them, so anyone can understand the ins and outs of why and how to prune or remove the different crown parts (5-year-old and above crown parts, 2–4-year old parts or 1-year-old parts) to achieve specific results, whether it be apple, pear or cherry trees etc. Our database comprises thousands of pictures that will walk you through the entire fruit tree pruning process, without you even having to leave your desk. There is an old proverb that also applies to pruning: „The wise man learns from the mistakes of others, the fool has to learn from his own”. Our program aims to help students by presenting a number of bad examples along with their corrections as well as photos of ideal ways to prune multiple different crown shapes. Using our web-based tool eliminates time and space limitations, i.e. you can access our interactive contents to gain or extend your pruning skills, irrespective of the pruning time and location.

Fractionation of chicken egg proteome by isoelectric point in liquid phase
Published March 20, 2014
39-42

The application of proteomics is relevant to physiology, reproduction, immunology, muscle and lactational biology in animal science, altough its use is still limited. One of the greatest challenges of proteome analysis is the reproducible fractionation of the complex protein mixtures. The fractionation methods can increase the probability of bi...omarker protein discovery. The fractionation by liquid-phase isoelectric focusing is one of the prefractionation methods. As a result, protein fractions can be easily collected, pooled and refractionated. There is a lack in the knowledge of gel-based proteomic methods of egg as only a limited number of protocols can be found in the literature, thus sample purification and fractionation require a time consuming optimisation procedure. The aim of this study was to fractionate egg yolk and white proteins by isoelectric point in liquid phase.

Estabilishing Plant Production Systems by Optimising the Crop Structure

In our days, ecologiacal and economic models of agricultural application are of ever increasing significance.

The relevant literature divides models according to various criteria. The most... common is the division between optimising and non-optimising models. Non-olptimising models generally endeavour to make the best use of technological lines, of machine capacity, while optimising models are used to optimise revenues returns from sales; or occasionally, production costs. In our case revenue and returns from sales were optimised. The models examined consists of several modules. These are the following: plant cultivation modules, evaluations (assessment of situation, conception plan, complex corporate evaluation), supplementary sheets (sheets and charts for ancillary plant production, general costs of operation, summary and crops structure optimisation).
