The agrotechnical significance of leguminous crops, in particular soybeans, consists in its ability to provide a huge bulk of vegetable protein and less nitrogen depletion of soils than non-legume crops [2]. Despite the fact that nitrogen symbiotically fixed by soybean plants is alienated with the harvest and taken out of the field with organic residues of leguminous crops, more nitrogen remains in the soil after them than with residues of other crops. In this regard soybeans are good predecessors in various stages of crop rotation. The article discusses topical issues of increasing productivity of leguminous crops, in particular, soybeans, when using different doses of ammophos against the background of its placement in various ways of main tillage of drained leached chernozems. In 2018–2019 studies were carried out to establish the influence of the optimal dose of mineral nutrition and the best method of soil cultivation on the productivity and quality indicators of soybeans of the French selection of the Amphora, Mentor and Isidor varieties. According to the results of the research, different effectiveness of the considered variants of the experiment was established. Thus, higher rates of soybean yield were noted in the later-maturing Isidor variety within 2,03–2,30 t/ha for plowing, and 1,70–1,91 for soil disking. The most cost-effective dose of mineral nutrition for all studied soybean varieties was the dose of 50 kg/ha of Ammophos (N6H26) against the background of plowing, where the profit from the increase in yield relative to the control was in the range of 2900–3650 rubles/ha, and against the background of disking soil the dose of Ammophos was 100 kg/ha (N12H52), where the profit was in the range of 1300–2050 rubles/ha.

Spring wheat is the main grain crop. Stable production of high-quality wheat grain is the key to the country's food independence. Therefore, the study of the elements of growing spring wheat technology, aimed at increasing the productivity of crops, is important. The study of the interaction of plants and microorganisms depending on the level of mineral nutrition in crop planning is currently ofparticular relevance. The use of biological products, growth regulators improves the mineral nutrition of plants, increases productivity and its quality, and also provides savings in mineral fertilizers. In the upper Volga region, the main spring crops are wheat, barley and oats. To further increase them in the region, it is necessary to study the characteristics of the formation of yields and determine the most productive crops depending on the level of nutrition, biological products and growth regulators. The scientific article presents the results of the study of these drugs on the productivity of spring wheat. In field experiments, it was planned to get 30, 40 and 50 tons of grain per hectare. Fertilizers for the planned harvest were made taking into account the agrochemical properties of the soil. From biological products used Flavobacterin, which has a protective effect against diseases and improves product quality, from growth regulators used agrochemicals HUMATE + 7 (10 % liquid concentrate), which is characterized by high biological activity. The yield level was determined taking into account the average long-term moisture supply and qualitative assessment of arable land. The indicators of photosynthetic activity of crops, crop and its structure, quality characteristics of grain and economic efficiency of growing spring wheat in the upper Volga region are presented. As a result of researches the optimum level of mineral nutrition for wheat, the efficacy of agrochemical diazotroph and programming yields of spring wheat, determined the photosynthetic activity of crops and grain yield, calculated economic efficiency of the studied techniques and established the qualitative characteristics of the crop. The program for obtaining the planned wheat yields in the years of the experiments was completed by 68-91 %. Close to the planned the program was implemented using a biological product and growth regulator-74-91 %.

Plant Protection System

The purpose of the research was to study the effect of mineral fertilizers and plant protection system on the vegetation index NDVI and its seasonal dynamics in agrocenoses of spring barley with overseeding of perennial grasses in the North-West of Russia. The data obtained indicate that against the background of the deficiency of the main elements of mineral nutrition in the second half of the growing season of spring barley, a significant phytomass of perennial grasses is formed in the crop, which account for 36.7%. This leads to a smaller decrease in the NDVI index (by 0.06) than in the fertilized variants (0.20). The value of NDVI index reflects not only the state of cultivated plants and weed infestation of crops, but also the level of development of crops, growing under vegetation. The influence of mineral nutrition developed during the period of maximum values of the index, which were recorded 6-8 weeks from the sowing date and 26-30 weeks from the beginning of the year. Under the influence of average doses of fertilizers, the NDVI index increased by 0.09...0.2 (on average 0.13), under the influence of high doses – by 0.13...0.26 (on average 0.18). The influence of plant protection system was expressed by a decrease in the phytomass of weeds (by 49.4...68.9%), at the same time the mass of spring barley and perennial grasses increased (by 1.7...18.5% and by 11.7...43.5% respectively). Carrying out the whole complex of protective measures led to a decrease in the NDVI index values by 0.01...0.06, depending on the phytosanitary situation in the agrocenosis. The most reliable forecast of the yield of spring barley can be implemented in the period from 5 to 7 weeks from the beginning of the emergence of barley shoots, especially against the background of the use of plant protection products that eliminate the influence of harmful organisms on the formation of the crop and the optical properties of crops

The decrease in soil fertility is the main cause of low crops yields in Burkina Faso. It is therefore necessary to make a supply of fertilizers to increase yields. This is the reason why during the 2015 rainy season from July to October, a study was conducted on sesame fertilization in Souri located in the Province du Mouhoun. The goal of our study is to fertilize plants with increasing doses of mineral fertilizers at different application dates on sesame. The objective is to determine the optimum dose and date of fertilizer application to increase the yields. For this purpose four NPK (14-23-14) fertilizer treatments have been experimented with following doses NPK0 (0kg.ha-1), NPK50 (50 kg.ha-1) NPK100 (100kg.ha-1) NPK150 (150 kg.ha-1) with three application dates (sowing, 15 DAS, 30 DAS) in Fisher’s completely randomized blocks with four replications in split-plot. The results showed that NPK doses had an effect on sesame throughout morphological development (height, number of ramifications, number of capsules) and yield performance. Yields have increased according to the doses applied in the following order: NPK0 (226 kg.ha-1) < NPK50 (348 kg.ha-1) <NPK100 (550 kg.ha-1) <NPK150 (593 kg.ha-1). Through economic calculations, the NPK100 dose with 550 kg.ha-1 yield can be chosen as the most cost-effective dose for producers. The application dates of NPK had various effects on sesame that emerged on the height and grain yield. The plants had the best performance on the date of application of the 15 DAS (475 kg.ha-1) followed by the application at planting time (450 kg.ha-1) and at the end the application on 30 DAS (375 kg.ha-1). Interaction between the doses and the dates of application of fertilizer is significant and should be considered in sesame. La baisse de la fertilité des sols est une cause des faibles rendements au Burkina Faso. Ainsi, il faudra faire de bons apports d’engrais pour augmenter les rendements. Dans ce cadre, une étude a été conduite de juillet à octobre 2015 à Souri dans la Province du Mouhoun. Il s’est agi d’apporter des doses croissantes de fumure minérale à différentes dates d’application sur le sésame. L’objectif est de déterminer la dose et la date d’application optimales de la fumure minérale. A cet effet quatre traitements de doses d’engrais NPK (14-23-14) : NPK0 (0 kg.ha-1), NPK50 (50 kg.ha-1), NPK100 (100kg.ha-1), NPK150 (150 kg.ha-1) ont été appliqués selon trois dates d’application (au semis, le 15ème JAS, le 30ème JAS) dans un dispositif expérimental en blocs de Fisher à 4 répétitions avec un arrangement en split-plot. Les résultats obtenus ont montré que les doses NPK ont un effet positif sur le sésame à travers son développement morphologique (sa hauteur, ses ramifications, ses capsules) et son rendement. Les rendements obtenus ont permis de classer les doses selon cet ordre croissant : NPK0 (266 kg.ha-1) <NPK50 (348 kg.ha-1) <NPK100 (550 kg.ha-1) <NPK150 (593kg.ha-1). L’évaluation économique effectuée sur la base du ratio valeur sur coût (RVC) a permis de retenir la dose NPK100 comme étant la plus rentable pour les producteurs. Les dates d’applications NPK sur le sésame ont également des effets visibles sur la hauteur et le rendement en grain. Le meilleur rendement est obtenu avec l’application du NPK 15 JAS (475 kg.ha-1) suivi de l’application au semis (450 kg.ha-1) et enfin de celle effectuée au 30ème JAS (375 kg.ha-1). L’interaction doses et dates d’application d’engrais NPK doit être considérée chez le sésame.

The influence of various levels of mineral nutrition on the accumulation of plant-root residues of spring wheat and oats in the conditions of the forest-steppe zone of Western Siberia is studied. The natural agricultural background of leached chernozem was taken as a control. The research was carried out at the station of the Department of Soil Science and Agrochemistry of the State Agrarian University of the Northern Trans-Urals. In the experiment, various doses of mineral fertilizers were used, ensuring the yield of grain crops from 3.0 to 6.0 t/ha. It was found that the mass of plant-root residues of spring wheat and oats has no significant differences and depends on the level of mineral nutrition. On the natural agricultural background, the mass of plant-root residues is 3.24-3.88 t/ha. Fertilization increases the yield of grain crops to 6.0 t/ha, and also increases the amount of plant-root residues: spring wheat - 4.47; oats – 6.04 t/ha. Increasing the doses of mineral fertilizers reduces the ratio of yield to the mass of plant-root residues from 1:1.6 to 1:1.10 units. It was found that almost half of the root system of spring wheat and oats is located in a layer of 0-10 cm, while the share of roots in a layer of 30-40 cm accounts for no more than 16% of the mass.

Culture Of Assessment

Purpose – The purpose of this paper is to analyze the process of developing an academic library assessment plan and its relation to the furtherance of a culture of assessment. Design/methodology/approach – Qualitative study of a university library’s assessment planning process; findings based on documentary evidence as well as an employee survey; analysis framed in relationship to relevant literature. Findings – Planning for the future of assessment offered the Jerry Falwell Library a significant opportunity for organizational change. Evaluations of the planning process were mixed, but generally revealed evidence of conditions associated with the development of a culture of assessment. Participants saw planning as the product of both external and internal factors. The plan’s orientation toward value and impact, though clearly understood, was not universally appreciated. Implementation of the plan remains a substantial challenge. Research limitations/implications – Reliability is subject to the limitations inherent to qualitative methods. Single case study design limits generalizability to different contexts. Practical implications – The goal of developing a culture of assessment is not to be achieved easily or quickly. Library employees may be most inclined to support an assessment agenda when it is driven by internal factors such as quality improvement and the pursuit of efficiency and effectiveness. Originality/value – The study emphasizes the process of developing an assessment plan at a university with a strong teaching mission. Additionally, it provides insight into the relationship between assessment planning and a culture of assessment.

An increase in spring barley acreage requires a detailed study of the interaction of agronomic and climatic factors, as well as the selection of a modern set of new varieties. The use of mineral fertilizers is one of the most important methods to improve the productivity of grain crops and maintain a deficit-free balance of mineral nutrients in arable soils. The current study of the effective use of various doses of mineral fertilizers (NPK) on the new spring barley variety ‘Znatny’ was carried out on dark-gray forest heavy loamy soil in 2018–2020 by the Institute of Seed production and Agrotechnologies, a branch of the Federal Budgetary Scientific Institution “Federal Research Agro-Engineering Center VIM”. There has been established that the date of the phenological phases and the length of interphase periods did not depend on fertilizer rates, but had a close correlation with weather conditions (r = +0.68). The analysis of the obtained data has shown that an increase in the rates of applied fertilizers increases the aboveground biomass, which, in turn, negatively affects productivity of the barley variety ‘Znatny’ (r = -0.77). The analysis of the yield structure and rates of fertilizers NPK has shown that in the trial, the spring barley productivity was influenced by 1000-grain weight (r = +0.60). There was found a high inverse correlation between productivity and length of head (r = -0.85). When length of head ranged from 7.5 to 8.4 cm, grain weight per head remained practically at the same level in all variants (1.1–1.2). This indicated that at a rate of N90P90K90 and N120P120K120, the variety ‘Znatny’ formed a not very dense head. Protein percentage at these rates also greatly reduced. According to the obtained data, an increase in the doses of applied fertilizers (N90Р90К90–N120Р120К120) resulted in the intensified development of most leaf diseases and a decrease in lodging resistance. Thus, the optimal dose of application of azophoska fertilizer on dark-gray forest soil is the norm N45P45K45, since on this option there was obtained maximum productivity and net income. the increase in the recom[1]mended norms of mineral fertilizers, sharply reduces profitability of crop cultivation.
