PRODUCTIVITY OF PEPPER CULTIVATED AT AN ORGANIC FARM UNDER THE INFLUENCE OF THE BIOFERTILISER LUMBRICAL

Veselka Vlahova

Abstract


The biological system (agroecosystem) is considered to be a living organism having mutually connected components in dynamic interrelations. In Bulgaria there have been many Lumbrical farms established, which have been producing large quantities of biofertiliser obtained as a result of feeding California red worms with organic remainders until their complete transformation into warm excrements. This study aims at researching the impact of the biofertiliser Lumbrical on the yield upon organic production of pepper of the variety of Sofiiska Kapiya. The experiment was carried out in the vegetation years of 2010 and 2011 at the Agroecological Center at the Agricultural University- Plovdiv, on the territory of an organic farm certified by “Balkan Biocert” LTD. The highest standard yield was reported for the variant characterized with additional vegetative soil feeding with Lumbrical on the basic fertilisation Lumbrical - 1883 kg/da (2010); 1872 kg/da (2011). The results show the stimulating effect of the basic fertilisation with the biofertiliser Lumbrical and additional (soil and leaf) vegetation feeding with the biofertiliser Lumbrical on the economic productivity of pepper.
