In recent years, biofertilisers have emerged as a promising component of an integrated nutrient supply system in agriculture. The objective of this study was to examine the influence of selected biofertilisers on the vegetative growth, the content of N, P2O5 and K2O in the leaves and stems, and on the physiological parameters of pepper of the variety of ‘Sofiiska Kapiya’ cultivated under organic agriculture conditions. This experiment was carried out from 2009 to 2011 on the experimental fields of the Agroecological Centre at the Agricultural University-Plovdiv (Bulgaria), situated on the territory of a certified ecological farm. The study included the following biofertilisers – Boneprot, Lumbrical, Baikal EM “Effective Microorganisms”, Emosan, and Bio One. The results of the biometric measurements of the average plant height at the end of the vegetative period showed the highest values for the variant treated with Emosan on the Boneprot basic fertilisation (62.60 cm – 2009; 64.80 cm – 2010, and 63.87 cm – 2011). Upon feeding with the biofertilisers Emosan and Baikal EM on basic fertilisation with Boneprot (2009, 2010 and 2011) at the pepper mass fruit yield stage, plants showed higher values of net photosynthesis (PN) that were also similar to the high values observed in the flower bud stage. The highest intensity of transpiration (ȿ) was observed for the variants treated with the biofertilisers Baikal EM (2009 and 2011) and Emosan (2010) on basic fertilisation with Boneprot. It was concluded that the feeding with Emosan stimulated the vegetative growth of the pepper plants due to the high concentrations of nutrient-providing proteins contained in this biofertiliser. The results showed that biofertilisers do not significantly impact the P content of the pepper leaves and stems, but changes were more obvious in the leaves. The fertilisation with the studied biofertilisers increased the K2O content in leaves and stems compared to the control (non-fertilised) plants; the values were higher for the leaves.

W ostatnich latach bionawozy pojawiły się w rolnictwie jako obiecujący element zintegrowanego systemu dostarcznia składników odżywczych. Celem niniejszego badania było zbadanie wpływu wybranych bionawozów na rozwój wegetacyjny i zawartość N, P2O5 oraz K2O w liściach i łodygach, a także na parametry fizjologiczne papryki rocznej odmiany ‘Sofiiska Kapiya’ uprawianej w warunkach rolnictwa organicznego. Doświadczenie przeprowadzono w latach 2009–2011 na polach doświadczalnych Ośrodka Rolniczo-Ekologicznego Uniwersytetu Rolniczego Plovdiv (Bułgaria) położonych na certyfikowanej farmie ekologicznej. Badanie dotyczyło następujących bionawozów: Boneprot, Lumbrical, Baikal EM “Effective Microorganisms”, Emosan oraz Bio One. Wyniki pomiarów biometrycznych przeciętnej wysokości rośliny pod koniec okresu wegetacyjnego wykazały największe wartości dla odmiany, której aplikowano Emosan przy podstawowym nawożeniu Boneprotem (62,60 cm – 2009; 64,80 cm – 2010 oraz 63,87 cm – 2011). W przypadku podawania bionawozów Emosan i Baikal EM przy podstawowym nawożeniu Boneprotem (2009, 2010 oraz 2011) na etapie plonowania owoców papryki, rośliny wykazywały wększe wartości fotosyntezy netto (PN). Wartości te były podobne do dużych wartości zaobserwowanych na etapie pąków kwiatowych. Największą intensywność transpiracji (E) zaobserwowano u odmian, którym podawano bionawozy Baikal EM (2009 i 2011) oraz Emosan (2010) przy podstawowym nawożeniu Boneprotem. Wyciągnięto wniosek, iż zastosowanie Emosanu stymuluje wzrost wegetacyjny roślin papryki ze względu na wysokie stężenia białek dostarczającyh elementów odżywczych zawartych w tym bionawozie. Wyniki wykazały, że bionawozy nie wpływają w sposób istotny na zawartość P w liściach i łodygach papryki, ale zmiany były bardziej oczywiste w liściach. Nawożenie badanymi nawozami zwiększało zawartość K2O w liściach i łodygach w porównaniu z kontrolą (rośliny nienawożone), a wartości te były większe dla liści.
