Response of New Yellow Lupin Varieties to Inoculation with <i>Bradyrhizobium</i> sp. <i>Lupinus</i> under Central European Conditions

The aim of a two-factorial field experiment was to determine how the inoculation of seeds/soil with preparations of Bradyrhizobium sp. Lupinus (Nitragina—seed inoculation, Nitroflora I—seed inoculation, Nitroflora II—soil inoculation, HiStick® Lupin—seed inoculation) affected plant development, seed chemical composition and yield of two yellow lupin varieties (Bursztyn, Puma). This experiment was carried out with four replications in 2018 and 2019 in Poland. Precipitation during both vegetation periods was similar to or lower than the long-term mean. Average seed yield of Puma was significantly greater than Bursztyn (by 0.22 t ha−1). According to the correlation coefficients, seed yield was mainly related to plant height, dry mass of nodules per plant and mass of 1000 seeds. Our results suggest that legumes, such as lupin, should always be inoculated with Bradyrhizobium, especially if they are cultivated for the first time in a field. For optimal results, the highest-quality preparations should be used. In our study, the best results were observed after HiStick® Lupin inoculation, which resulted in the highest protein content, seed yield and protein yield across all treatments

QUALITY AND HYGIENIC CONDITIONS OF WHITE LUPIN SILAGE, AFFECTED BY FORAGE STAGE OF GROWTH AND USE OF SILAGE ADDITIVES

ABSTRACT A two-factor field experiment with white lupin cv. Butan was carried out. The first factor was the green forage harvest date (the flat pod stage -Cut 1 and the stage of green ripe seeds -Cut 2), while the second one -application of silage additives: biological (strains of lactic acid bacteria) and chemical (a mixture of organic acids), and the control treatment (without additives). In Cut 2 higher fresh matter (FM) and dry matter (DM) yields were obtained. Silage inoculated with the biological additive contained a significantly greater count of lactic acid bacteria. Both additives reduced counts the Clostridium bacteria, yeasts and mould fungi. The silage with the chemical additive had a three-fold higher content of water-soluble carbohydrates (WSC), while the biological additive increased lactic acid (LA) levels. White lupin can be used as a silage raw material, but plants before ensiling should be partially wilted and silage additives should be applied

Optimizing the Amount of Nitrogen and Seed Inoculation to Improve the Quality and Yield of Soybean Grown in the Southeastern Baltic Region

The cultivation of soybeans, especially where this species has not been grown in large areas, requires the determination of the optimal mineral nitrogen fertilization and seed inoculation with Bradyrhizobium japonicum. The purpose of the study was to determine the optimal dose of mineral N fertilization and seed inoculation treatments with B. japonicum under field conditions in the southeastern Baltic region. The objective of this study was to achieve nitrogen supply and/or inoculation with B. japonicum: check-0 kg N ha−1, 30 kg N ha−1, 60 kg N ha−1, HiStick® Soy + 0 kg N ha−1, Nitroflora + 0 kg N ha−1, HiStick® Soy + 30 kg N ha−1, HiStick® Soy + 60 kg N ha−1, Nitroflora + 30 kg N ha−1, Nitroflora + 60 kg N ha−1. Higher yields of seeds, protein and fat were found after application HiStick® Soy compared to Nitorflora. The inoculation with B. japonicum together with nitrogen fertilization improved crude protein content in seeds, biometrical features, yield components and especially the seed yield of ‘Aldana’ soybean. The highest seed yield was found after the application of HiStick® Soy and nitrogen fertilization in doses 30 kg N ha−1 or 60 kg N ha−1. Compared to the control, combined B. japonicum inoculation and nitrogen fertilization in soybean cultivation proved to be a significant factor in improving the productivity of this species in southeastern Baltic conditions

Wpływ wybranych szczepów Trichoderma spp. na wartość siewną i wigor nasion łubinu wąskolistnego

Laboratory analyses were performed at the Department of Agronomy, the Poznań University of Life Sciences. Experiments were conducted on two strains of Trichoderma ssp. to investigate the aftereffect of sprinkling irrigation of blue lupin plants and seed soaking time (20, 40, 60 min). Results indicate a significant effect of Trichoderma ssp. strain and sprinkling irrigation on basic parameters of the value and vigour of blue lupin seeds. The greatest values of germinating energy and germination capacity were recorded after the application of the strain T. atroviride. Sprinkling irrigation deteriorated seeds sowing value and seed vigour in blue lupin. Seed soaking time did not modify germination energy or germination capacity, while significant differences were found in the seedling growth test, seedling growth rate test and the vigour index.Badania laboratoryjne wykonano w Katedrze Agronomii Uniwersytetu Przyrodniczego w Poznaniu. Doświadczenia uwzględniały dwa szczepy Trichoderma ssp., następczy wpływ deszczowania roślin łubinu wąskolistnego oraz czas moczenia nasion (20, 40, 60 min). Uzyskane wyniki wskazują na istotny wpływ szczepu Trichoderma ssp. oraz deszczowania na podstawowe parametry wartości siewnej oraz wigor nasion łubinu wąskolistnego. Najwyższą energię i zdolność kiełkowania odnotowano po zastosowaniu szczepu T. atroviride. Deszczowanie pogarszało jakość siewną i wigor nasion łubinu wąskolistnego. Czas moczenia nasion nie wpływał na energię i zdolność kiełkowania, ale istotne różnice stwierdzono w przypadku testu wzrostu siewki, testu szybkości wzrostu siewki oraz indeksu wigoru

The effect of soil type and soil additives on the selected growth parameters and yield of flowerheads of Calendula officinalis L.

Introduction: Soil additives, which usually contain nutrients and microorganism, can improve soil conditions for plants. There are still few papers dedicated to the application of soil additives in herb plants, especially in calendula
