The Impact

The research explores the relation between productivity of binary grass mixture and mineral nutrition. The hypothesis assumes that nutrient value of the same forage depends on mineral nutrition of forage grasses. According to purpose of research, the authors specified the task which is seen to analyze the impact of mineral fertilizers on productivity and nutrition of forage mass of binary grass mixture sown under the cover. The object of the research is a binary grass mixture based on alfalfa (Medicago + sainfoin). Sowing was carried out under the barley and Sinapis cover on two mineral backgrounds: control (without fertilizers) and fertilized. Fertilizers were applied the day before sowing. Crop yield and the quality of harvested mass were assessed in the appropriate period which was the stage of Medicago budding. Two-year industrial and economic experiment highlighted necessity and efficiency of sowing Medicago binar grass mixtures under Sinapis cover with 25% lower sowing rate and apply mineral fertilizers dosed as N23P60K60 in the forest-steppe of Novosibirsk region. This application contributed to the highest output of metabolic energy in dry matter (37 GJ/ha). The authors observed a positive tendency on harvesting from 1 ha of fodder units (2.14 tons), digestible protein (0.35 tons), as well as the yield of dry (3.58 tons) and green mass (13.7 tons). In this variant the authors observed the highest output of metabolic energy in dry matter (37 GJ/ha). There was a positive tendency to harvest fodder units (2.14 tons), digestible protein (0.35 tons) pro 1 ha and get dry (3.58 tons) and green mass (13.7 tons).

The results of long-term experiments on the productivity and feed value of Festulolium herbage mixtures with meadow clover and variegated alfalfa have been presented. It has been found that in mixed crops with the participation of Festulolium the productivity and quality of herbage mass were higher than in traditional crops. In mixed clover crops with Festulolium the yield of herbage mass was higher by 8,7–14,1 % and amounted to 41,3 and 43,5 t/ha, dry matter 6,89 and 7,60 t/ha, collection of feed units 6,13 and 6,94 thousand/ha, digestible protein 663 and 690 kg/ha, respectively, in the control and against the background of mineral nutrition. The supply of a feed unit with digestible protein reached 106–108 g, the sugar-protein ratio was 0,79–0,82, which corresponds to zootechnical standards or close to them. Herbage mixtures of alfalfa with Festulolium formed yields of herbage mass 42,9 t/ha, dry matter 9,29 t/ha, feed units 8,73 thousand/ha, digestible protein 1103 kg/ha in control and 47,9 t/ha, 9,89 t/ha, 8,73 thousand/ha, 1160 kg/ha, respectively, when applying mineral fertilizers, which was higher than traditional herbage mixtures by 9,2–14,0 %. When the ratio of sugar and protein was close to the optimal ratio (0,77–0,81), the supply of digestible protein to the feed unit significantly exceeded the norm (132–140 g). Joint crops of cereals and legumes are also important agrotechnical value. Due to the nitrogen-fixing symbiotic activity of legumes when they are grown together with cereals, nitrogen is transferred from legumes to cereals, which completely eliminates or significantly reduces the need for such crops in mineral fertilizers.

Dry Substance

In accordance with the accepted norms for feeding cattle, absolutely dry substance of herbal food should contain 10-12% of digestible protein, 20-22% of fiber, 4-6% of fat, 6-8% of ash and 40-42% of nitrogen-free extractives with exchange energy of 14-16 MJ. Such high quality indicators are leguminous perennial grasses, cultivated on optimal backgrounds of mineral nutrition, which is also characteristic of clover meadow of Ranniy 2 variety. However, only due to the legumes of perennial grasses can not completely solve the problem of balancing the diet of feeding animals, since they differ extremely low content of sugars. Meanwhile, in the dry matter of ryegrass, the content of the sum of sugars reaches 20 percent or more. In this connection, this article deals with the cultivation of clover-ryegrass grass stands on the calculated background of mineral nutrition in order to increase the volume of production of energy-saturated feeds balanced by the sugar-protein ratio.

The expediency of fusarium resistant lupines usage in organic farming for improving soil fertility and producing high protein feed for livestock is justified in this article. Organic production excludes the use of mineral fertilizers and pesticides. In these circumstances, increases the value of cultures that positively affect the fertility of soils and their phytosanitary status. These crops include annual fodder lupine (yellow, white and angustifolia), especially varieties that are resistant to disease. Having the highest nitrogen-fixing ability among annual legume crops, lupins, depending on the type and conditions of cultivation, can accumulate from 80 to 300 kg/ha of environmentally pure symbiotic nitrogen in biomass. Plowing the green mass (30-45 t/ha) is equivalent to the corresponding amount of manure or introduction of 5-7 t/ha of ammonium nitrate. 30 kg/ha of phosphorus and 50 kg/ha of potassium are entering the soil with plant remains. Therefore, lupine provides itself with nutrients and still leaves up to 150 kg/ha of nitrogen in the soil after harvesting for subsequent crops in crop rotation. In organic production, fusariosis resistant varieties of lupines are also interesting as a source of high protein feeds for livestock. They are building up to 60 t/ha of biomass, which contains more than one ton of digestible protein. In grain of the fodder varieties contains 40-52% of crude protein, 5.5-6.0% of fat, 10-12% of sugar. The characteristic of fusarium resistant varieties of lupins (yellow, white and angustifolia), created in the NSC "Institute of Agriculture NAAS" and included in the Register of Plant Varieties of Ukraine is presented in this article. These varieties are practically not affected by fusariosis under the production conditions and do not require the use of fungicides during the growing season. They can be grown in crop rotation with a return period of 2-3 years, whereas for unstable it took 6-7 years. Because of the inability to use in organic farming fungicide to prevent crop losses from anthracnose, it is necessary to use predominantly angustifolia lupine varieties, which are now more tolerant to this disease, prevent sowing of infected seeds and adhere to crop rotation. Fusarium-resistant varieties of lupins are suitable for cultivation in poucous and sown crops, and in mixtures with other crops.

Опыты проводили в 2018–2020 годах на экспериментальной базе «Коренево» (Московская область) в условиях дерново-подзолистой супесчаной почвы Центрального региона Нечерноземной зоны России. Цель исследований – изучить реакцию нового среднеспелого сорта картофеля Сигнал селекции ФГБНУ «ФИЦ картофеля имени А.Г. Лорха» на сроки, густоту посадки и приемы внесения минеральных удобрений по комплексу хозяйственно ценных признаков (морфологические и биологические особенности, потребительские и столовые качества клубней, урожайность, показатели качества клубней, устойчивость к болезням, лежкость при хранении). Выбор исследуемых агроприемов обусловлен необходимостью ускорения появления всходов, последующего развития растений и формирования достаточно значимого уровня урожая клубней до наступления неблагоприятных метеорологических условий (жара, засуха), а также обеспечения бесперебойного питания растений в течение всей вегетации, так как на супесчаных почвах во время выпадения осадков происходит вымывание питательных веществ в недоступные для корневой системы растений слои. Клубни высаживали в два срока: ранний (третья декада апреля при температуре почвы не ниже 5–7 °C) и базовый (контроль) – через 7–10 дней после первого срока. Посадку проводили на фоне удобрений, внесенных локально тремя приемами при нарезке гребней и последующих междурядных обработках двумя лентами: 1. Основное N90P90K135(контроль); 2. Дробное №1 (стартовое N60P60K90+ подкормка N30P30K45 через 7–10 дней после всходов); 3. Дробное №2 (стартовое N30P30K45 + подкормка N30P30K45 через 7–10 дней после всходов + подкормка N30P30K45 в фазе бутонизации). Густота посадки: 44, 50 и 56 тыс. клубней/га по схеме 75×30; 75×27 и 75×24 см. Определен наиболее эффективный комплекс агроприемов, включающий раннюю посадку (третья декада апреля при температуре почвы не ниже 5 °C) с густотой 44 тыс. клубней/га на фоне дробно-локального внесения удобрений (№1). В условиях дерново-подзолистой супесчаной почвы Центрального региона Нечерноземной зоны сорт дает прибавку урожая в размере 3,9 т/га, или 10,3%. При этом условный доход составляет 43,0 тыс. р/га. Ключевые слова: агротехнологический паспорт, урожайность, срок, густота посадки, прием внесения, потребительские и столовые качества, условный доход. The experiments were carried out in 2018–2020 at the experimental base Korenevo (Moscow region) in the conditions of sod-podzolic sandy loam soil of the Central region of the Non-Chernozem zone of Russia. The aim of the research is to study the reaction of a new medium-ripe potato variety from the selection of Russian Potato Research Centre on the timing, planting density and methods of applying mineral fertilizers according to a complex of economically valuable characteristics (morphological and biological features, consumer and table qualities of tubers, yield, quality indicators of tubers, disease resistance, shelf life). The choice of the studied agricultural practices is due to the need to accelerate the emergence of seedlings, the subsequent development of plants and the formation of a sufficiently significant level of tuber yield before the onset of adverse meteorological conditions (heat, drought), as well as to ensure uninterrupted nutrition of plants throughout the growing season, since on sandy loam soils during precipitation, nutrients are leached into layers inaccessible to the root system of plants. Tubers were planted in two terms: early (3rd decade of April at a soil temperature not lower than 5–7 °C) and basic (control) – 7–10 days after the first term. The planting was carried out against the background of fertilizers applied locally in three methods when cutting the ridges and subsequent row-to-row treatments with two tapes: 1. Basic N90P90K135 (control); 2. Fractional No1 (starting N60P60K90 + top dressing N30P30K45 7–10 days after germination); 3. Fractional No2 (starting N30P30K45+ top dressing N30P30K45 7–10 days after germination + top dressing N30P30K45 in the budding phase). Planting density: 44, 50 and 56 thousand tubers/ha according to the scheme 75×30; 75×27 and 75×24 cm. The most effective agro-complex of techniques was determined, including early planting (3rd decade of April at soil t not lower than 5 °C) with a density of 44 thousand tubers/ha against the background of fractional local fertilization (№1). In the conditions of sod-podzolic sandy loam soil of the Central region of the Non-Chernozem zone, the variety gives an increase in yield of 3.9 t/ha, or 10.3%. At the same time, the conditional income is 43.0 thousand rub/ha.

The objective of this study was to evaluate the effect of planting alfalfa (Medicago sativa L.) with- and without cover crops on forage dry matter yield and nutritive values of alfalfa in Kansas, USA. In the first production year 2014, dry matter yield of mono-culture alfalfa appears to be compatible or even higher than planting with certain species of winter annual forages as a cover crop. Alfalfa planted with a combination of four different multi-species winter annual forages such as oats (Avena sativa L.), oilseed radish (Raphanus sativus L.), annual ryegrass (Lolium multiflorumL.), and turnip (Brassica rapa L.) had the highest dry matter yield of alfalfa in 2014.Dry matter yield of alfalfa in 2nd production year 2015 was similar to alfalfa + oats and alfalfa + oats + oilseed radish + annual ryegrass + turnip or significantly higher than alfalfa planted with annual ryegrass, oilseed radish, and turnip together. Based on two year of data in 2014 and 2015, the highest alfalfa yield occurred when alfalfa was planted with a combination of oats, oilseed radish, annual ryegrass, and turnip. The lowest dry matter yield of alfalfa occurred when alfalfa was planted with annual ryegrass.No significant differences in crude protein (CP), acid detergent fiber (ADF), and neutral detergent fiber (NDF) were found when comparing alfalfa monoculture with alfalfa + oats, alfalfa + oilseed radish, alfalfa + oats + oilseed radish + annual ryegrass + turnip, and alfalfa + turnip treatments. When considering both dry matter and nutritive values of alfalfa, planting alfalfa with cover crops appears to be compatible or better practice than planting alfalfa monoculture.

AbstractExperiments were made to study the proportion, chemical composition, and rumen degradability of the morphological components of barley straw (Corgi variety) and to study the selection of these components by sheep. The proportions in the harvested straw dry matter (DM) as leaf blade, leaf sheath, stem and chaff were 128, 314, 500 and 58 g/kg DM, respectively. The different components of straw on analysis proved to have very different concentrations of nitrogen and neutral-detergent cellulase digestibility. The leaf blades had the highest and the stems the lowest values. The degradabilities of DM in the components and in the whole straw were determined by measuring DM loss from samples incubated in nylon bags for various periods in the rumen of sheep. Responses were measured using the mathematical model p = a+b (1–e−ct) where p is DM loss, (a+b) potential degradability, c the rate constant of DM loss and t is the time of incubation. DM losses decreased in the order leaf blades > leaf sheath > whole plant > chaff > stems. Leaf blades also had the highest potential degradability and rate of degradation.In another trial, five sheep were offered unchopped barley straw ad libitum. There were five treatment periods in which sheep were allowed to leave uneaten proportionately 0·2, 0·3, 0·4, 0·5 and 0·7 of the straw on offer for assessing the animal's selection of the morphological components of that straw. The amount of leaf blade in the material consumed increased in largely a linear (P < 0·01) fashion with the amount of excess allowance. The proportion of stem eaten varied conversely. The selection of leaf sheath was less apparent. Little stem was consumed until the proportion of leaf blade in the food available decreased below proportionately 0·4. The practical significance of the study is discussed.

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.

In order to evaluate genetic variability and estimation of remobilization related traits in wheat using biometrical genetic techniques an experiment was conducted in a randomized complete blocks design with three replicates under post-anthesis drought stress conditions in the Campus of Agriculture and Natural Resources, Razi University, Kermanshah, Iran during 2011-2012 cropping season. The results of analysis of variance showed significant differences between the genotypes for all studied traits except current photosynthesis (CP) and current photosynthesis share into kernel yield (CPSKY). High genetic gain and broad sense heritability estimates were observed for penultimate remobilization share into kernel yield (PenRSKY) and internodes remobilization share into kernel yield (IRSKY) indicating high genetic potential, low effect of environment and predominant role of additive gene effect on their expression. Spike dry matter remobilization (SDMR), spike dry matter remobilization efficiency (SDMRE) and spike remobilization share into kernel yield (SRSKY) exhibited the highest phenotypic and genetic positive correlation with kernel yield (KY). Moreover, the highest genotypic and phenotypic covariance was observed between kernel yield (KY) and SDMR, CP, SDMRE and SRSKY, respectively. The highest environmental covariance was identified between kernel yield (KY), peduncle dry matter remobilization (PedDMR) and penultimate dry matter remobilization (PenDMR), respectively. High co-heritability was detected between SDMRE and PedDMR, PedDMRE and PenDMR and between peduncle remobilization share into kernel yield (PedRSKY) and internodes dry matter remobilization efficiency (IDMRE), suggesting that selection of either of the traits would simultaneously affect the others, positively.
