Abstract The article is devoted to the urgent need for improvement and unification of systems for the quality evaluation of feed and rations. Lack of uniform sampling methods, analysis methods, feed quality indicators; norms of the nutrient requirements depending on the physiological state of animals, a unified approach to balancing diets, and most importantly - the absence of an international standard system for assessing the energy nutritive value of feed and rations - complicates the mutual understanding of scientists and practitioners from different countries and the integration of scientific achievements into agricultural production.

Object-level saliency detection is an important branch of visual saliency. In this paper, we propose a novel method which can conduct object-level saliency detection in both images and videos in a unified way. We employ a more effective spatial compactness assumption to measure saliency instead of the popular contrast assumption. In addition, we present a combination framework which integrates multiple saliency maps generated in different feature maps. The proposed algorithm can automatically select saliency maps of high quality according to the quality evaluation score we define. The experimental results demonstrate that the proposed method outperforms all state-of-the-art methods on both of the datasets of still images and video sequences.

The features of the organization of production units agroclusters, which are one of the components of land management projects which aimed at organizing the rational and efficient use of available land resources are described in this article. The term “cluster” is a French word that means “bundle”, “collection” in Uzbek. It can be taken as “the geographical proximity of enterprises and institutions cooperating with each other in a particular field”. The development of value-added production in the agricultural sector and the development of this market requires ensuring product quality standards, full use of scientific and scientific achievements in the processing process, development of existing research institutes and using the potential of geographical location. In our view, the solution of this problem can be found in the agricultural production system through the organization of cluster production, which is used by developed countries in America, Europe and Asia.

The low nutrient availability rainfall patterns regimes are the main constraints to agricultural production in Niger. This was a study of the decomposition and mineralization of nutrients of four types of composts (M1P, M2P, M1H and M2H) in a sandy soil. It was carried out at the experimental N'Dounga station (CERRA Kollo) located about 15 km from Niamey. A randomized blocks design with five repetitions was used. For the evaluation of yield, two doses (1 t ha-1 and 1.5 t ha-1) were applied per millet. Decomposition and mineralization were assessed after burial at 10 cm depth between of a small bag containing 100 g (five small bags / compost). The characterization of the physico-chemical elements of composts samples after incubation has shown that composts are rich in nutrients. Nitrogen ranged from 0.8% to 1.1%, phosphorus from  9.99 mg.kg-1 to 12.76 mg.kg-1 and potassium from 19.94 cmolc dm-3 to 26.26 cmolc dm-3. All four composts are basic (pH> 7). Compost M2H lost more than 80% of its weight during the 10 weeks of the experiment compared to 48% for the M1P. the mineralization of N, P and K is greater at compost M1P (83.6% N, 72.72% P and 89.5% K). This compost also gave the highest yield (1272.5 kg ha-1). The decomposition and mineralization of the main elements (N, P and K) allow the synchronization between the release of nutrients from these composts and the nutrient requirements of millet in a sandy soil.

Article is devoted quality, production and use of prewilted silage as a best kind of ensilage forage. In a review the forage names are considered. According to the theory of operationalism in 60s years of last century there was introduced a term “haylage”, and in 2010 and 2014 in Belarus (СТБ 1223), and then in the Russian Federation (ГОСТ Р 55986) the term “prewilted silage”. In Germany the prewilted silage (“Spitzensilage”, “Topsilage”) is considerd as a main kind of forage for cows, yielding 10000 L milk pro year. Now the annual volume of prewilted silage production in the Russian Federation exceeds 10 million tons. In some books published last years the information on a chemical composition and nutritive value of prewilted silage produced in the Vologda region and Udmurtiya Republic is reported. Mainly the article is devoted analysis of these data, examples of different quality prewilted silage are given, progressive methods for preparation of a highly nourishing forage are recommended. Foreign and domestic prices on fodder analyses are pointed out. It is recommended to improve system of a forage quality evaluation and use in an animal feeding formula.

The aim of this study was to investigate fodder quality and nutritive value of different grass-legumes mixtures influenced by various level of N fertilization. Studied factors had an impact only on the content of crude protein (CP), crude protein yield (CPY) and nitrate content in the forage. The level of N fertilizer showed a highly significant and positive impact on the CP and nitrate content. Treatment with 210 kg N ha-1 is characterized by the highest content of CP and nitrate of 189.7 g kg-1 DM and 2524 ppm, respectively, and the highest protein yield of 1.95 t ha-1. The value of nitrate in the forage does not exceed the limit that is considered hazardous to the health of animals. Energy value of forage obtained from the grasslands of ME ?7.75 and NEL?4.32 MJ kg-1 DM is lower than values obtained in other studies.

Zambian small-holders are dependent on natural grazing to supply the nutrient requirements of their cattle. During the dry season grazing is severely limited, production declines steeply, reproductive cycles become dormant and new-born calves are subject to a high mortality rate. A potential supplemental feed, maize stover, is poorly exploited resulting in extensive field losses. Collection and controlled feeding would greatly increase its efficiency of use, plus such a feed system offers the opportunity to chemically treat the maize stover pre-feeding. This study was conducted to identify the degree to which the nutritive value of this material could be improved using such techniques.

The agricultural industry in the Russian Federation is dynamically developing; the agricultural export amounts to $ 25 billion. In other countries, in turn, this figure is much higher, for example, in China it has exceeded $ 75 billion. The existing potential can be realized if the efficiency of agricultural production is increased by creating and implementing automation, robotization, digital technologies, and artificial intelligence. As a result it may lead to a 2.5-3.5-fold increase in labor productivity; a 2-3-fold increase in the yield of crops; a 3-4-fold cut in energy consumption and material costs, ensuring the ecological safety of agricultural production and the environment. The authors developed the concept of intelligent agriculture and identified the following areas of digital technology applications: integrated production management; digital technologies in crop production, animal husbandry, energy supply, products storage and processing ; digital engineering for rural areas. The authors presented the stages of agricultural production digitalization, including: a system for monitoring the conditions and parameters of agricultural production; information transmission system; artificial intelligence and cloud technologies, setting the foundation for management decision-making; the implementation of management decisions by robotic devices. The authors presented the examples of using digital technologies in soil cultivation, horticulture, animal husbandry, and artificial ecosystems. In animal husbandry, these technologies prove to facilitate the monitoring of the animals movement, their physiological state, parameters of the microclimate on the premises, feed and milk quality control. The Federal Scientific Agroengineering Center VIM is reported to have the necessary educational infrastructure, accredited Master’s and postgraduate studies for training specialists in digital agriculture.
