EFFECT of digestates derived from the fermentation of maize-legume intercropped culture and maize monoculture application on soil properties and plant biomass production

BackgroundThe use of maize-legume mixed culture to produce renewable energy and fertilizers by anaerobic fermentation (AD), while respecting soil quality is a favourable approach in sustainable farming. This paper investigates how the substrate (silage) composition affects the quality of digestate and thus its effect on selected soil parameters (respiration, content of carbon and nitrogen). The high content of remaining nutrients (mainly N) in the AD residual biomass of digestate may increase the biomass of amended plants. One objective of this study was to determine the composition of different digestates produced by anaerobic fermentation of the biomass of intercropped (mixed) cultures. Other objectives focused the digestate impact on soil properties and yield of tested plant (lettuce) in a pot experiment, carried out under controlled conditions in the growth chamber for 6 weeks. Variants tested in the pot experiment included negative control, maize (Zea mays L.) digestate, broad bean (Vicia faba L.) digestate, white lupine (Lupinus albus L.) digestate, maize + broad bean digestate, maize + white lupine digestate.ResultsAs compared to maize, silage from the mixed culture (or legumes) positively affected the properties of digestate (content of N, P, K, Acid Detergent Fibre (ADF), Neutral Detergent Fibre (NDF), Acid Detergent Lignin (ADL). The effect of digestate application on soil parameters depended on the digestate composition: the highest basal respiration was induced by digestates with the increased content of dry matter and ADF – maize + broad bean and white lupine. The broad bean variant showed glucose-induced respiration 0.75 (μg CO2·g-1 h-1), while the lowest value was in the maize variant (0.45 μg CO2·g-1 h-1). The application of digestate derived from the mixed culture increased the plant biomass more than that of single maize silage digestate (+ 14% in the maize + broad bean variant and + 33% in the maize + white lupine variant).ConclusionsA potential was found of silage made of leguminous plants to increase the digestate N content. Nevertheless, it is desirable to increase the C/N ratio by raising the amount of C containing substances. Fertilization with digestate showed a potential to increase the plant biomass (compared to the unfertilized control); however, differences among the individual digestates were not observed. The benefit of legume added to the maize-based silage was proven, especially the contribution of nutrients to arable soil.Graphical abstract

Growing Triticum aestivum Landraces in Rotation with Lupinus albus and Fallow Reduces Soil Depletion and Minimises the Use of Chemical Fertilisers

In north-western Spain, the cultivation of wheat landraces represents the pillar of quality Galician bread; today, a minimum of 25% Galician flour is required to produce bread under the auspices of the Protected Geographical Indication “Pan Galego”. The main objective of this study was to evaluate the effect of the rotation of two wheat landraces—‘Carral’ and ‘Caaveiro’—with lupin (sweet Lupinus albus), together with a fallow period, on crop yield and quality, as well as the environmental benefits of rotations over conventional monoculture systems. After the different agricultural activities, twelve agronomic parameters were analysed at the end of the third year. For the environmental analysis, the Life Cycle Assessment methodology was applied. The results showed a positive influence of rotation systems on wheat yield and quality parameters, reporting higher specific weight and lower impurities compared to monoculture. No significant differences were observed between wheat rotation and monoculture in other parameters related to baking quality, such as protein, wet gluten, baking strength (W), elasticity (L), tenacity (P), and swelling (G). However, soil quality influenced wheat quality independently of rotation, and higher organic matter and lower phosphorus produced higher W and P, respectively. Moreover, rotation had a positive effect on yield, up to 62% when fallow preceded wheat, and in reducing diseases, pests, and weeds. Finally, in terms of environmental performance, the best results were identified when lupin preceded wheat due to lower fertiliser application. In this regard, the worst profiles corresponded to the scenarios based on monoculture for both wheat landraces.

The use of white lupine in complete feed for trout

The article presents the material on the most up-to-date, the global problem of protein deficiency in complete feedback for fish. One of the ways to solve this problem may be the use of white lupine (Lupinus Albus) in the structures of feed recipes. An important condition for the successful development of fish farming and the implementation of planned products for the production of products, to ensure food safety, occupy feeding issues. The decision of this issue puts a number of tasks to ensure feedback, rational methods of production, on the basis of advanced scientific achievements that contribute to the technological, economic development of the industry. Therefore, in experienced formulations of complete feed, the main task was to replace the white most expensive protein component into Lupine, that is, fish flour. In the first experienced recipe, the amount of lupine natives was 10%, which made it possible to reduce the fisherous flour content by 7%. The second experimental recipe in its structure contained lupine white without a shell in an amount of 22%, this made it possible to reduce the content of fish flour by 14%. The third experienced rechart contained Lupine without a shell of 25%, which made it possible to reduce the content of fish flour by 19%. Consequently, the use of white lupine in the formulations of complete feed, makes it possible to improve their nutritional value. And the use of lupine without a shell makes it possible to replace high-fingered animal feed in greater volume.

In Silico Analysis and Functional Characterization of Antimicrobial and Insecticidal Vicilin from Moth Bean (Vigna aconitifolia (Jacq.) Marechal) Seeds.

Vicilin has nutraceutical potential and different noteworthy medicative health-promoting biotic diversions, and it is remarkable against pathogenic microorganisms and insects. In this study, Vigna aconitifolia vicilin (VacV) has been identified and characterized from the seed of Vigna aconitifolia (Jacq.) Marechal (Moth beans). LC-MS/MS analysis of VacV provided seven random fragmented sequences comprising 238 residues, showing significant homology with already reported Vigna radiata vicilin (VraV). VacV was purified using ammonium sulfate precipitation (60%) followed by size exclusion chromatography on Hi-Load 16/60 Superdex 200 pg column and anion-exchange chromatography (Hi trap Q FF column). Purified VacV showed a major ~50 kDa band and multiple lower bands on 12% sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) under both reduced and non-reduced conditions. After all, a three-dimensional molecular structure of VacV was predicted, which showed β-sheeted molecular conformation similar to crystallographic structure of VraV. All Vicilins from V. aconitifolia and other plants were divided into six sub-groups by phylogenetic analysis, and VacV shared a high degree of similarity with vicilins of Vigna radiata, Pisum sativum, Lupinus albus, Cicer arietinum and Glycine max. Additionally, VacV (20 μg) has significant growth inhibition against different pathogenic bacteria along strong antifungal activity (50 μg). Likewise, VacV (3.0 mg) produced significant growth reduction in Rice Weevil Sitophilus oryzae larvae after 9 days compared with control. Furthermore, by using MMT assay, the cytotoxicity effect of VacV on the growth of HepG2 liver cancerous cells was tested. VacV showed cytotoxicity against the HepG-2 line and the acquired value was 180 µg after 48 h. Finally, we performed molecular docking against caspase-3 protein (PDB ID: 3DEI) for VacV bioactive receptor interface residues. Hence, our results reveal that VacV, has nutraceutical potential and moth beans can be used as a rich resource of functional foods.

Weed Competition Effects on Growth and Yield of Spring-Sown White Lupine

White lupine (Lupinus albus L.) is an annual legume that is grown for both seeds and green biomass, but several agronomic aspects of this crop, including response to weed competition, have not been studied extensively. Field experiments over two growing seasons (2012 and 2016) were carried out in Orestiada, Greece, to study the growth and development of spring-sown white lupine under season-long weed competition from natural weed flora compared with its growth without weed competition. Treatments were arranged in a randomized complete block design with four replications and included (i) a non-treated (weedy) control, where weeds (Chenopodium album and Sorghum halepense) remained in the plots throughout the experiments and (ii) a weed-free control, where weeds were removed upon crop emergence and the plots were kept free of weeds throughout the experiments by hand removal. The presence of Chenopodium album and Sorghum halepense reduced the aboveground dry matter accumulation of white lupine ‘Multitalia’ at 7 weeks after crop emergence by 18.0% in the first growing season and 29.5% in the second growing season, while the corresponding decrease in the aboveground dry matter accumulation at 9 weeks after crop emergence was 25.3 and 33.4%. However, the reduction in dry matter accumulation was limited to lower levels after flowering (9.9% in the first and 12.8% in the second growing season). In both growing seasons, values of the ability to withstand competition (AWC) index were lower at 7 and 9 weeks from crop emergence than at maturity. Seed yields were 1.58 Mg per ha under weedy conditions and 2.20 Mg per ha under weed free conditions in the first growing season, and 1.59 and 2.32 Mg per ha, respectively, in the second growing season. The values of the relative yield loss (RYL) index for seed yield were 28.2% in the first growing season and 31.5% in the second growing season. Overall, white lupine growth and seed yield was significantly affected by the occurrence of weeds mostly at the early vegetative stages, resulting in the potential yield not being achieved due to weed competition. Future research on weed competition across several sites and years would be useful to define more clearly the critical period of weed control in white lupine.

The potential of alternative seed treatments to control anthracnose disease in white lupin

White lupin (Lupinus albus L.) is a promising crop to meet the rising global demand for plant-based protein. The seed-borne pathogen Colletotrichum lupini, however, threatens lupin cultivation worldwide. Seed dressings using synthetic fungicides were shown effective to reduce infection levels, but their negative environmental impact and exclusion from organic production calls for more sustainable solutions. In this study, a total of eleven different alternative seed treatments were tested in field trials in Switzerland between 2018 and 2021. Treatment types consisted of: hot water, steam, electron, long-term storage, elevated partial pressure of oxygen (EPPO), vinegar, plant extracts and biological control agents (BCAs). The BCAs were tested for potential antagonistic activity against C. lupini during white lupin infection under controlled conditions prior to field trials. Long-term storage and vinegar treatments successfully reduced disease incidence and increased yield to levels similar to those observed for certified seeds, without significantly affecting germination rate. Although promising, effectiveness of these treatments needs further validation. Four BCAs showed significant disease reductions under controlled conditions. Besides lowering disease severity, two BCAs also reduced C. lupini DNA in stem tissue. These reductions, however, were not observed in the field, highlighting the importance of field validations. The treatments identified in this study provide a solid basis for the development of sustainable and effective seed protection strategies in white lupin to control C. lupini successfully.

The Highly Repeat-Diverse (Peri) Centromeres of White Lupin (Lupinus albus L.)

Plant genomes are known to be mainly composed of repetitive DNA sequences. Regardless of the non-genic function of these sequences, they are important for chromosome structure and stability during cell-cycle. Based on the recent available whole-genome assembly of white lupin (Lupinus albus L.; WL), we have in silico annotated and in situ mapped the main classes of DNA repeats identified with RepeatExplorer. A highly diverse and an abundance of satellite DNAs were found representing more than 10 families, where three of them were highly associated with CENH3-immunoprecipitated chromatin. Applying a strategy of several re-hybridization steps with different combinations of satDNA, rDNA, and LTR-RTs probes, we were able to construct a repeat-based chromosome map for the identification of most chromosome pairs. Two families of LTR retrotransposons, Ty1/copia SIRE and Ty3/gypsy Tekay, were highly abundant at pericentromeric regions, while the centromeric retrotransposon of WL (CRWL) from the CRM clade showed strong centromere-specific localization in most chromosomes and was also highly enriched with CENH3-immunoprecipitated chromatin. FISH mapping of repeat DNA showed some incongruences with the reference genome, which can be further used for improving the current version of the genome. Our results demonstrate that despite the relatively small genome of WL, a high diversity of pericentromeric repeats was found, emphasizing the rapid evolution of repeat sequences in plant genomes.

Plant Density and Time of White Lupine (Lupinus Albus L.) Relay Cropping with Tef (Eragrostis tef (Zucc.) Trotter) in Additive Design in the Highlands of Northwest Ethiopia

Agronomic strategies such as choosing the optimal row ratio and planting legume crops at the right time are crucial for enhancing crop productivity. A field experiment was conducted in 2016 and 2017 to assess the influence of plant density and lupine intercropping time on tef field productivity. The treatments were as follows: tef was planted at a 20 cm inter-row spacing, lupine was sown at 20 and 40 cm inter-row spacing (row ratio of 1 tef: 1 lupine and 2 tef: 1 lupine) and lupine intercropped three times (1, 2, and 3 weeks after tef planting). Randomized complete block design (RCBD) with 3 replications were used. Two sole tef and lupine were planted. The results revealed 40 cm inter-row spacing and delayed lupine intercropping (3 weeks after tef planting) provided the maximum tef grain yield of 1.80 t ha−1. The sole cropping of lupine produced the highest lupine grain yield (2.63 t ha−1). Lupine intercropping at 40 cm inter-row spacing and two weeks after tef planting resulted in the highest land equivalent ratio (1.54), tef equivalent yield (2.45 t ha−1), area time equivalent ratio (1.11), system productivity index (2.5), monetary advantage index (15206 birr ha−1), net benefit (65109 birr ha−1), and marginal rate of return (602%). Therefore, farmers in the northwest Ethiopian highlands should consider intercropping lupine two weeks after tef planting in-between two rows of tef as an effective intercropping system.

Hypothesis of the formation of bacterial blights on secondary moistened cotyledons of soybean and other leguminous crops

The article examines cotyledonous bacterial blight – a possible causes of the decrease in seed sowing quality of leguminous crops. The article presents the hypothesis that there is another cause for the development of cotyledonous necroses, regardless of species, variety, and crop’s cultivation area. The secondary (rain) moistening of mature seeds leads to the development of cotyledonous necroses and a decrease in seed germination of soybean, white bean, chickpea, white lupin, and blue lupin due to the subsequent necrotization of over-moistened areas of cotyledon tissues. The secondary moistening of mature seeds can lead to the development of cotyledon necrosis and a decrease in germination of soybean seeds, white beans, chickpeas, white lupin and blue lupin due to subsequent necrotization of waterlogged areas of cotyledon tissues. The symptoms of cotyledon necrosis development during secondary moistening of mature seeds and cotyledonous bacterial blights are almost identical in all leguminous crops. Bacterial pathogens of various species and families are isolated on the dead areas of cotyledons. This fact can be explained by the repeated saprophytic infection of cotyledon sites.

Identification and expression analysis of phosphate transporter (PHT) gene family in Lupinus albus cluster root under phosphorus stress.

According to global estimation, 5.7 billion hectares of agricultural land contain limited phosphorus (P) availability leading to insufficient plant growth and productivity. Internal phosphate transporters play an essential role in mediating P mobilization and uptake from the soil. White lupin (Lupinus albus) is a cluster root (CR) forming crop with great potential to survive under P limited soil. However, it is imperative to identify and characterize the phosphate transporter (PHT) gene family in plants to validate their involvement in solving P deficiency problems. The recent availability of white lupin high-quality genome allowed us an exhaustive searches in the whole genome and identified five phosphates transporters subfamilies, including 35 putative genes that are unevenly distributed on 16 chromosomes. The LaPHT1 subfamily contained eight genes, LaPHT2 subfamily have three, LaPHT3 subfamily have eight, LaPHT4 subfamily have nine, and LaPHO subfamily has seven. Gene structure and duplication were also examined in detail. Syntenic analysis revealed that white lupin PHT family members had maximum the collinear relationship with those in L. angustifolius followed by Phaseolus vulgaris but showed the least collinear relationship with those in Arabidopsis. Gene ontology (GO) analysis revealed that the in white lupin PHT genes were enriched in functions regulated P uptake, transport, and recycling mechanisms. RT-qPCR was performed to evaluate the transcript levels of LaPHT genes in different parts of CR under P deficient hydroponic culture. Our study would provide better understanding the genetic evolution and expression phosphate of phosphate transporters in L. albus CR under P deficiency. It will also be helpful for further functional-based studies to solve P deficiency-related issues and mitigate P stress responses.

Evaluation of the modern lupine varieties developed in the All-Russian Lupin Scientific Research Institute

The article presents the researches of the Institute within the frame of the breeding program for three cultivated lupine species: Lupinus albus L., Lupinus angustifolius L. and Lupinus luteus L. The authors analyze and compare the modern varieties of the cultivated lupine species included to the State Register of Breeding Achievements of Russia for the complex of economic-and-biological characters. The narrow-leafed lupine is the most early ripening; it allows to grow it in the most northern regions. The yellow lupine is the most adapted to light sandy loam soils. Its protein content in seeds is 45-50%. The white lupine has the highest grain productivity (5-6 t/ha) among grain legumes crops. Its grain quality is close to soya one (protein and oil content is 36-40% and 9-12% respectively).

Effect of substrate properties and phosphorus supply on facilitating the uptake of rare earth elements (REE) in mixed culture cropping systems of Hordeum vulgare, Lupinus albus and Lupinus angustifolius

This study presents how phosphate (P) availability and intercropping may influence the migration of rare earth elements (REEs) in legume–grass associations. In a replacement model, Hordeum vulgare was intercropped with 11% Lupinus albus and 11% Lupinus angustifolius. They were cultivated on two substrates, A (pH = 7.8) and B (pH = 6.6), and treated with 1.5 g P m−2 or 3 g P m−2. Simultaneously, a greenhouse experiment was conducted to quantify carboxylate release. There, one group of L. albus and L. angustifolius was supplied with either 200 µmol L-1 P or 20 µmol L-1 P. L. albus released higher amounts of carboxylates at low P supply than L. angustifolius, while L. angustifolius showed the opposite response. Plants cultivated on substrate B accumulated substantially higher amounts of nutrients and REE, compared to substrate A. Higher P supply did not influence the leaf and stem P concentrations of H. vulgare. Addition of P decreased REE accumulation in barley monocultures on alkaline soil A. However, when H. vulgare was cultivated in mixed culture with L. angustifolius on alkaline substrate A with high P supply, the accumulation of REE in H. vulgare significantly increased. Conversely, on acidic substrate B, intercropping with L. albus decreased REE accumulation in H. vulgare. Our findings suggest a predominant effect of soil properties on the soil–plant transfer of REEs. However, in plant communities and within a certain soil environment, interspecific root interactions determined by species-specific strategies related to P acquisition in concert with the plant’s nutrient supply impact REE fluxes between neighbouring plants.

Ethylene works as a possible regulator for the rootlet elongation and transcription of genes for phosphorus acquisition in cluster roots of Lupinus albus L.

ABSTRACT White lupin (Lupinus albus L.) plants are tolerant plants under phosphorus (P)deficiency. They form unique morphological roots, so-called cluster roots (CRs) under P deficiency. CRs contribute to P absorption by the expansion of the root surface area and P mobilization activities. Previous research has implied the involvement of several hormonal functions in CR formation. Ethylene is a key regulator responsible for the modification of root architecture and P acquisition in response to low P in plants. However, understanding the effect of ethylene on CR morphogenesis is not enough. Here, the focus was on the effects of ethylene on CR morphology and gene expression for P acquisition. First, a reanalysis of public RNA-Seq data indicated that the gene expression for ethylene synthesis was induced during CR maturation. In turn, the 10-days application of an ethylene synthesis inhibitor, CoCl2, and an ethylene precursor, ACC, to CR formed in hydroponic culture without P was performed. CR morphology, transcript levels of the genes related to P acquisition, and citrate concentration in roots were determined. The results indicated that the elongation of rootlets in CR was promoted in a Co2+ concentration-dependent manner, suggesting that ethylene is responsible for the arrest of rootlet elongation. mRNA accumulation for acid phosphatases, phosphate transporters, citrate synthases, and a putative citrate transporter increased in ACC-treated immature CR, suggesting that ethylene induces the transcription of genes for P acquisition. Additionally, the trend of citrate concentration in roots among treatments was similar to that in the expression of citrate synthases, supporting that ethylene accumulation promotes citrate synthesis. The roles of the arrest of rootlet elongation and regulation of gene expressions for P acquisition are considered independent functions of ethylene. It was concluded that ethylene works as a possible regulator for the rootlet elongation and transcription of genes for P acquisition in CRs, although further studies are required to elucidate the molecular mechanisms of the arrest of rootlet elongation and transcriptional regulation.

Review on Nutritional, Anti nutritional Content and Effect of Processing on Anti Nutritional Content of Lupine in Ethiopia

White lupine is a traditional crop in Ethiopia. It is grown in the north western part of the country. Lupine has been used as human nutrition especially the protein content is very high (40%) which can solve the malnutrition problem in Ethiopia. The utilization of lupine is limited by small scale of their production, market and the anti nutritional content. The utilization can increase using effective anti nutritional removing methods. Alkaline thermal treatment, Aqueous thermal treatment, Extrusion cooking are efficient methods to remove anti nutrients in lupine. Nowadays in Ethiopia by safe processing using traditional processing methods(roasting followed by socking) by removing of Anti nutritional factor applied in the production of different kinds of Functional foods such as cooked, roasted , ground and mixed with cereal flour in the production of bread, snack, Injera , Shero, Kolo(roasted food), Nefro(cooked food).

Nitrogen transfer from legume green manure in a crop rotation to an onion crop using 15N natural abundance technique

Legumes as green manure allow adding N from the air to the soil through their biological fixation. The objective was to evaluate the effect of legume crops as green manure at the beginning of the rotation on soil quality and their N input to the following onion crop (Allium cepa L. var. cepa). Five crops were sown: faba-bean (Vicia faba L.), field pea (Pisum sativum L.), oat-vetch mixture (Avena sativa L. + Vicia atropurpurea Desf.), white lupin (Lupinus albus L.), and oat as control treatment, with four replicates. Prior to sowing soil was prepared with 20 Mg ha-1 compost and 715 kg ha-1 rock phosphate. Then, at 50% grain filling stage these crops were incorporated as green manure to the soil, followed by the onion crop. Biological N fixation (BNF) by 15N natural abundance technique parameters of green manure, yield, leaf N content of the legumes and onion, and soil bio-physicochemical properties were measured and analyzed by ANOVA and Tukey’s test for mean separation (P ≤ 0.05). Faba-bean treatment had the highest BNF (388 and 369 kg N ha-1 fixed in 2017 and 2018, respectively). For onion yield, just faba-bean and oat-vetch in 2018 reached the Chilean mean yield with 54.39 and 49.08 Mg ha-1, respectively. Control treatment yield was not significantly different. Leaf N content in onion remained within a normal range in all treatments. Adding green manure together with compost to the soil improved soil N and K contents.

White lupin (Lupinus albus L.) exposed to elevated atmospheric CO2 requires additional phosphorus for N2 fixation

PurposeThe steady rise of atmospheric CO2 concentrations enhances symbiotic N2 fixation and plant growth. However, it is largely unknown whether more P is required to enhance N2 fixation under elevated CO2. We examined if plants under elevated CO2 require more P to support enhanced N2 fixation.MethodsWhite lupin (Lupinus albus L. cv. Kiev) was grown in nutrient solution under ambient (380 ppm) and elevated (700 ppm) CO2 levels at 0, 2, 5, 12, 25 and 50 µM P. Nodulation, nodule function, N2 fixation and plant growth were assessed at 4 and 6 weeks post inoculation. Excess cation uptake and proton release were also analysed due to its importance in P acquisition.ResultsElevated CO2 increased the critical P concentration in nutrient solution for N2 fixation, indicating plants under elevated CO2 need to acquire additional P to support greater N2 fixation. Elevated CO2 improved N2 fixation in P-deficient plants by increasing specific nitrogenase activity. Elevated CO2 also enhanced excess cation uptake which increased proton release by roots.ConclusionsAs elevated CO2 increased the plant demand for P, it increased the critical P concentration in nutrient solution for N2 fixation, thereby plants require more P to mitigate the effect of P deficiency on N2 fixation. Despite this, elevated CO2 could enhance N2 fixation in P-limiting environments.

Application of new forms of fertilizers to improve productivity and grain quality of white lupine

Substantiation and development of technology elements for obtaining a sustainable productivity of lupine grain is an important and urgent task for expanding the area under this grain crop. There have been considered the study results of the effect of fertilizers ‘Aquamix ST’, ‘Metaborat Kaliya’, ‘Tiaton’ on productivity and grain quality of white lupine. The study was carried out at the All-Russian Research Institute of Lupine – a branch of the FWRC FPA, in the soil and climatic conditions of the southwestern part of the Non-Chernozem zone in 2018-2019. The purpose of the current study was to estimate the efficiency of these innovative micro- and macrofertilizers and the methods of their application on a number of indicators that improve productivity and grain quality of white lupine. The application of fertilizers ‘Aquamix ST’ and ‘Metaborat Kaliya’ contributed to an increase of white lupine grain productivity on 37.5 and 35.4%. There has been determined protein increase from 5.0 to 5.8% in grain of the white lupine variety ‘Piligrim’ in all application variants of ‘Aquamix ST’. The use of ‘Aquamix ST’ and ‘Metaborat Kaliya’ in the vegetation period of plants reduced alkaloid content of lupine grain on 24.7-34.6%. Application of ‘Aquamix ST’ and ‘Metaborat Kaliya’ in white lupine budding stage increased carotene content in grain on 34.3 and 25.0%, respectively. The analysis of the data showed that the variant including pre-seeding treatment with ‘Aquamix ST’ and subsequent treatment in the budding stage of plants was characterized by the maximum amount of lysine and carotene. There was noted that the application of micro- and macrofertilizers resulted in an increase in feed units and digestible protein. Application of ‘Aquamix ST’, including pre-seeding treatment and two treatments in the vegetation period of plants provided the largest yield of digestible protein (1.26 t/ha), 6.0 t/h of feed units, and 54.8 GJ/ha of exchangeable energy. ‘Metaborat Kaliya’, used in the treatment of plants in their budding phase, showed almost the same results. The options that combined high productivity with high grain quality were more valuable according their feed value.

Chemical Composition of Lupin (Lupinus spp.) as Influenced by Variety and Tillage System

Lupins are an important source of domestic protein in many countries, and are often considered as an alternative to soybeans, given their elevated and high-quality protein content, suitability for sustainable production and consumer acceptability. The aim of the research was to determine the effect of the variety (indeterminate and determinate) and tillage system (conventional—CT, reduced tillage—RT, no-tillage—NT) on the chemical composition of three lupin species seeds (narrow leaved lupin—NL, yellow lupin—YL, white lupin—WL). The protein content of the lupin seeds ranged from 323 g kg−1 DM in the narrow-leaved lupin ‘Dalbor’ to 445 g kg−1 DM in the yellow lupin ‘Lord’. The tillage system significantly influenced the crude protein content only in NL seeds, with the greatest value observed with the NT system. An evaluation of the amino acid composition of the protein in the lupin seeds showed that the differences depended largely on the variation between the species. The conducted research shows that the varietal differentiation in terms of the amino acid content was particularly evident in NL and YL, and, to a lesser extent, in WL.
