As follows from the analysis of the collected experimental material of long-term field trials of the Kursk Federal Agricultural Research Centre and generalization of the activities results of leading domestic research and educational institutions, as well as the practical results of many agricultural enterprises of the eastern part of Europe, we have identified the most effective conditions for the use of basic agricultural methods in wheat cultivation technologies as well as spring and winter barley, seed peas, buckwheat, grain maize, oats, millet and winter rye cultivation technologies of different levels of intensity which contribute to the rational use of available resources of agricultural producers based on the prevailing soil and climatic conditions. The technologies made it possible to prepare scientific-methodological approaches and a mathematical model to solve the problems of selecting an adaptive technology of crops cultivation. A normative-reference database for different types of crops cultivation technologies has also been made, including a list of zoned recognized varieties and hybrids of crops under study, necessary technology methods taking into account conditions of their effective use. Currently, an algorithm and the corresponding software are being developed to choose the most expedient technology of crop cultivation for specific soil and climatic conditions depending on a set of defining factors. There has been created software (in the form of a complex of programs for stationary computers and mobile electronic devices with the Android operating system. A specialized website has been developed. It provides a scientifically well-grounded selection of crops varieties and hybrids for the eastern part of Europa on the basis of user-specified conditions.

Andropogon gayanus Kunth var. bisquamulatus Hack, is a polymorphic bunch grass, widely distributed throughout most of the tropical and subtropical savannahs of Africa, south of the Sahara in areas with a long dry season. This grass was introduced into the Colombian Llanos from the Shika Agricultural Research Station, northern Nigeria, in 1974. Subsequent to its introduction, a series of agronomic trials were initiated by Centro Internacional de Agricultura Tropical (CIAT) at the Carimagua Research Centre and various national research institutions in Latin America to evaluate the potential of A. gayanus, primarily in the vast Ultisol and Oxisol savannah regions of the continent. As a result of further evaluation at a number of locations, accession A. gayanus var. bisquamulatus CIAT 621 was released in 1980 in Brazil as cv. Flanaltina and in Colombia as cv. Carimagua 1. During 1982–3 Peru, Venezuela and Panama subsequently released the same accession under the cultivar names of San Martin, Sabanero and Veranero, respectively. It is estimated that 168000 ha have been sown with A. gayanus in Brazil since 1982 (J. E. Ferguson, C. Sere and R. de Andrade, personal communication). Smaller areas have been established in other countries.

Pesticide Treatment

Complex field experiments were carried out in Agricultural research institute in 1969. The field trials included five different crop rotation systems. In each 6-field rotation system the specific percentage of cereals (%) varied from 50 to 100%, perennial grass (clover+ timothy) - 16.7 to 33.3%. The highest winter rye yields were obtained from crop rotation systems with cereal proportion up to 66%. Including buckwheat in the crop rotation winter rye cultivation is highly productive in crop rotation systems with cereal proportion even up to 83%. Yield of winter rye in long-term monocultural sowings decreases even up to 0.74h-1. Winter ryetreatment with herbicide Grodil increases its yield up to 0.40 ha'1. Foreplants of barley according to their good influence on barley yield (descending): buckwheat, oats, winter lye. Barley yield in long-term monocultural sowings decreases for up to 1.17 t ha-1.Oats in crop rotation systems with cereal proportion up to 83% had very low yield amount alterations after different foreplants. Essential oat yield decreasement was noticed in perennial monocultural sowings. The best foreplants for spring wheat are buckwheat and lupine. The highest yield of buckwheat is get from monocultural sowings, but using potatoes as buckwheat foreplant gives essential yield decreasement. Distribution of perennial weeds, especially quickgrass, is 7,4 times more in crop rotation systems with high cereal proportion than in systems where also buckwheat and potatoes are cultivated. Treatment of herbicides and fungicides is more effective in monocultural sowings than in crop rotational systems, however increasement of crop yield after pesticide treatment is less remarkable than if we follow right crop rotation and choose optimal foreplants for each culture. Latest results from years 2002 to 2004 are shown in this article and are considered to be an addition to previous publications.

The most valuable and widespread food crop is spring wheat. Soil and climatic conditions influence the grain productivity and quality. The grain quality is affected by air humidity, insolation, nitrogen content in the soil and agricultural technologies. In 2019–2020, on the experimental field of the agronomic faculty of Kazan State Agrarian University, studies aimed to identify the reaction of the Ulyanovskaya 105 spring soft wheat to meteorological conditions and agricultural background were carried out. The soil was light gray forest, medium loamy. The predecessor was winter rye after pure fallow. Meteorological conditions were favorable for the growth and development of spring wheat. In 2019, the HMC was 1.36, in 2020 – 1.13. The maximum yield in 2019 and in 2020 was obtained with the application of calculated doses of fertilizers when sowing 6 million viable seeds per hectare – 3.0–3.44 tons and 3.67–4.21 tons per hectare.

Widespread Dissemination

Population is growing and, at the same time, the need for food requires new methods of agriculture. Modern technologies help agrarian producers to improve yields in conditions where suitable fertile lands are decreasing every year and climatic conditions become unpredictable. In addition to global problems, agrarian producers face the competitiveness of large agrarian giants when business exists in tough market conditions. The use of the modern tools for improvement of productivity has influence on the big number of agricultural enterprises. The main obstacle to the widespread dissemination of these tools is the lack of experience in using modern means and technologies, including monitoring. The article discusses the most available method for entering to a new level of digitization, namely, monitoring with the help of satellites and drones. This method of increasing yields is widely used in the world, but is only beginning to gain popularity in Ukraine. The information which is provided in the article will help agricultural producers to assess the need of implementation of these tools for their own businesses and to understand the benefits of a particular method of monitoring. The article explains in an accessible way the advantages and disadvantages of modern methods of monitoring, mechanism of its action and implementation; provides a comparison of the quality of information of satellites and drones, and considers the problems and prospects of these methods of monitoring in the future.

A genetic collection of the genus Pelargonium L’Herit. ex Ait., with 40 % stock represented by Pelargoniumgrandiflorum hybridium hort., is originated at the Federal Subtropical Research Centre of the Russian Academy of Sciences. The main collection varieties, including Aristo, Elegance, Candy Flowers, Hazel and Bermuda, are foreign selections attaining their best qualities under optimal soil and climatic conditions. Cultivation in humid subtropics disturbs their growth and development, at the same time as deteriorating their productivity and ornamental value. The research aimed to study the hybrid stock towards the selection of hardiest, most ornamental and long-flowering forms corresponding to a specified variety model. The variety model developed for Russian subtropic agroclimate incorporated a main set of economically valuable and adaptively significant traits. Over 30 varietal crossbreedings have been conducted to select for promising recombinants and hybrid families. A high variability of phenotypic ornamental traits has been observed in the crosses offspring. We identified 15 promising hybrids from the total morphological trait combination. Adaptive selection against stress factors has been proved effective. The most successful combinations were Hazel Ripple x Yashma, Hazel Cherry x Rozovyy Briz and A. Darling x Rozovyy Briz. A subset of elite forms (Kd-15-43, Kr-16-28 and Kc-18-22) maximising the number of significant breeding traits have further been selected towards a higher total score (≥95). K.j.-17-15, Kq-18-04 and K.ya-16-03 were recognised promising for large-flowered form selection. The Yagodnyy Tsvet variety, Kv-18-01 and K.d.-18-09 hybrids (over 35 inflorescences) have been identified as sources for high flower production. K.p-17-65, Kr-16-28 and Kc-18-22 were the hybrids with flowering period exceeding 100 days. All crosses were based on Hazel as a maternal form sourcing the trait.

The experiment was conducted in an Inland Valley Swamp during the dry spell of 2017 laid out in a randomized complete block design (RCBD) three replications at the Kabala Horticultural Crops Research Centre (KHCRC) cropping site, Ogoo Farm of the Sierra Leone Agricultural Research Institute (SLARI), Freetown, Sierra Leone. Raised beds measuring 5m x 1m (6 m2) with a 1m furrow between beds. Inter and intra row spacing of 75 cm by 50 cm with two rows per bed and two seeds per hills were directly sown. The treatments constituted NPK 15:15:15 at the rate of 0, 90, 120 and 150 kg/ha designated as T1, T2, T3 & T4  and Two hybrids of okra were used as experimental materials obtained from Indo-American Hybrid Seed Company, India; Okra-WASA-HyOKR-1 and Okra-WASA-HyOKR-2. Seeds were treated with Thiram Poison for longevity. Result indicates T2 (25.2; 35.1 cm) and T4 (56.9 cm) treatments recorded tallest plant heights followed by T2 (24.0, 34.4 & 50.1 cm), while T1 (18.8, 28.4 & 33.3 cm) had the shortest plant heights at 4, 8 & 10 Week After Planting respectively. Similarly, T4 & T2 (38.9, 65.5 & 44.8 cm) exhibited the largest SG and T1 (21.7, 33.0 & 52.0 cm) the least values at 4, 8 & 10 Week After Planting. While, the widest and narrowest LA at 4, 8 & 10 Week After Planting was observed in T3 (131.3, 135.0 & 158.5 cm2) and T1 (120.8, 121.8 & 128.1 cm2). With respect to yield and yield components, the longest (22.0 cm) and heaviest (112.7 g) fruit were recorded by T3 followed by T2 (19.1 cm & 101.3 g) with T1 having the shortest (11.7 cm) and lightest (52.3 g). The width of pod in T3 (31.2 cm) was greater than the rest of treatments and as usual, T1 indicated the least value (14.6 cm) respectively. The average NP produced plant-1 was shown by T2 & T3 (4.0) with the least of fruit produced by T1 (2.0). Also, 100 seed weight, T3 (106.7 g) weighted the highest followed by T2 (103.3 g), while T1 (60.3 g) accounted for the lowest seed weight. Conclusively, the two materials are adaptable to the climatic conditions of Sierra Leone (Western area). Hence further evaluation required across vegetable growing zones.

Experiments were conducted during the winter seasons of 1992–93 and 1993–94 at the Lumle Agricultural Research Centre and its off-station research site at Lopre in Nepal to study the agronomic performance and profitability of barley (Hordeum vulgare) and peas (Pisum sativum) mixed intercropping (that is, without any row arrangement) in the subsistence farming systems of the Nepalese hills. Sole crops of barley (cv. Bonus and Local) at 100kg seed ha−1 were compared with a pure stand of peas (cv. Tikot Local) sown at 60kg seed ha−1 and with peas intercropped with both varieties of barley at 100:40 or 100:20 kg seed ha−1. Results across two locations for two seasons showed that the barley+peas intercropping was advantageous in terms of overall grain yield, land equivalent ratio (LER), monetary advantage, economic return and dietary provision in the subsistence farming system. It also provided yield stability under adverse climatic conditions. Barley genotypes differed in their suitability for intercropping with peas. The yield of Local barley was reduced when peas were intercropped with it at both seed rates but this was not so with Bonus. The most appropriate combinations to realize the maximum advantage from intercropping were Bonus barley+peas at 100:20 kg seed ha−1 and Local barley+peas at 100:40 kg seeds ha−1. A combination of Bonus barley and peas at 100:20 kg seed ha−1 enabled farmers to harvest an additional 400 kg grains ha−1 from peas without significantly reducing the grain yield of barley. The study also verified through formal experimentation that the traditional practice of mixing barley and peas is advantageous.
