Extracting semantic relationships between entities and objects has become very challenging with the development of Big Data, Semantic Search Engines, and Semantic Question Answering systems. It has become an important research topic in recent years and is more valuable in the fields of biomedicines, Taxonomies, Health Care Informatics, etc. When taxonomies are studied and examined semantically, the problem of relationship detection arises. This research presents a computation technique to make it fast and efficient by employing a very important Graph Theory technique. This technique is used in semantic hierarchal relationship extraction in taxonomy. Our study illustrates that the Depth First Search Algorithm can best contribute, to detect hierarchal relationships and can be applied in the performance improvement from a semantic aspect. The research proposes a simple computation technique SSM5 for hierarchal relationship detection from taxonomies using Ontology. The technique can be used in an extensive range of applications in domains like Taxonomies, Biomedical Literature Mining, Business Intelligence, Unstructured Electronic Text on the Web, and Semantic Information Retrieval.
This paper studies the cost and returns of chickpea (Cicer arietinum L.) crop production in Banda District of Bundelkhand Region (U.P.). It attempts to estimates the cost of cultivation, cost of production and benefit cost ratio (BCR) of chickpea crops of different categories of chickpea growers they were categorized into four groups on the basis of their size of holdings and also 120 farmers were selected purposively for the study. The analysis of chickpea cultivation indicates that the cost of cultivation, cost of production, net return and Benefit Cost Ratio (BCR), which increases with increases the size of farms. The average of cost and returns indicates that the total of chickpea cultivation was incurred in Rs.35941.05/ha. and net income was received Rs. 23103.82/ha. by the farmers. Further the average Benefit Cost Ratio (BCR) was estimated 1:1.64, which also indicates that the per unit profits earn by the growers from chickpea production in the Banda District.
The article considers the justification of the feasibility of using technological normatives to regulate the load on soils and eliminate their degradation, energy assessment of the impact of agricultural machinery, agronomic measures and technology in crop production on the indicators of structural and aggregate, humus and biological activity of soil. In the conditions of stationary experiment in the Right-bank Forest-steppe of Ukraine it is revealed that more than 60 years of use of meadow-chernozem soil under traditional system of cultivation with use of shelf plowing and various fertilization options: P60, P60K60, N90P60K60, N135P90K90 in 10-field crop rotation (clover, winter wheat, sugar beet, corn for silo, spring wheat, green peas, winter wheat, sugar beet, corn for grain, barley with clover) with did not significantly worsen any of the parameters of agrophysical and humus state, biological activity, quantitative and species composition of the microbiological pool. On the basis of the conducted researches the conceptual mathematical model of iteration, degradation of soil for soil protection systems of agriculture estimation is developed. Soil agrophysical indicators have different informativeness and different sensitivity. The sum of elementary soil particles and water resistance of aggregates by weighted average diameter, the amount of non-aggregated clay change quite easily under the influence of tillage, while the sum of water-resistant aggregates (> 0.25 mm), Bever and Roades aggregation coefficient and total clay content remain weakly sensitive. The humus content is the main indicator that determines the potential fertility of the soil. The newly formed "young" fractions (primarily labile humus) are the most sensitive to changes in cultivation technology, in contrast to the content of total humus. The guarantor of the quasi-stable humus state is the stability of the agrophysical framework of the soil system and the harmony of the microbiological pool, the quantitative and species composition of which determine the balance of the processes of synthesis and mineralization of humus. Energy assessment of technologies for growing crops in long-term field experiments allowed to determine technological normatives (Tn - the ratio of energy of crop residues to energy of fuels and fertilizers, the reduction of which begins soil degradation): for meadow- chernozem soil - 8.6.
The article presents the results of research for 2018-2020 concerning formation of fodder productivity by the dry mass outcome of meadow clover different varieties per 1 ha depending on the methods of sowing on different backgrounds of fertilizers on typical low-humus black soils of Forest-steppe of Ukraine. On average, in the first three years of life and usage, meadow clover provides productivity of dry mass outcome per 1 ha - 8.22-9.88 tons, which depends little on sowing methods. When inoculating seeds with nodule bacteria in combination with application of fertilizer in the doze of N60P60K90 the productivity increases by 8-12% comparing to the variant without fertilizers. And, with separate application of fertilizers (Р60K90 or N60P60K90) or inoculation of seeds on the background without fertilizers the productivity increases only by 4-6%. Among fertilizers, the highest payback from 1 kg of fertilizer (6-7 kg of dry mass) is provided by application of N60 on the background of Р60K90. In the first year, sowing under the cover of spring barley provides 22-25% higher productivity than uncovered sowing, and in the second and the third years, uncovered sowing provides 7-10% higher productivity than sowing under the cover of spring barley. The most productive variety is Typhoon, which is 0.10-0.66 t/ha of dry mass superior to the varieties Lybid and Tina. Fertilizer factor is the most influential by dry mass outcome per 1 ha, and in the first year - the method of sowing with a share of 55%.
Research results on study of the influence of different methods of cultivation on performance of oat on soddy-podzolic soils under the conditions of the Eastern Carpathian Foothills of Ukraine are given. Plowing to a depth of 20-22 cm and 14-16 cm has been established to form the highest yield of oat grains at the level of 3.5-3.45 t/ha, which is 0.2-0.15 t/ha more than surface tillage. Maximum protein content has appeared to be when plowing the soil to 20-22 cm - 9.7%. Herewith, natural weight of oat grains decreased by 1.9%, and hull content increased by 3.6 relative percent compared to disk plowing.
