Effects of natural substance (Biohumus and Baykal EM1) on certain morphological-physiological processes of Amaranthus caudatus var. bulava and Amaranthus tricolor var. Valentina on Bartın climate conditions and uses on landscape architecture

In this study prepared as doctoral thesis, the effects of natural substances (Baykal EM1 and Biyohumus) on morphological and some physiological processes of Amaranthus caudatus var bulava and Amaranthus tricolor var valentina species, being annual plants grown naturally in Bartin province were researched.Morphological (length, number of leaves, width of leaves, number of flowers, the length of flowers, trunk diameter, fresh root weight) and some physiological (chlorophyll a, b, a+b, caratenoid, amaranthin, nitrogen, protein, DNA and RNA amounts) processes of Amaranthus caudatus var bulava and Amaranthus tricolor var valentina were taken into account.The study was carried out in two different ecosystems as in the garden of Günye Forest Enterprise of Bartin Forest Directorate in 2006 and 2007 and in the garden of Hacettepe University Inkumu facilities in 2007. In each of experimental areas 3 different applications(Baical EM1, Biohumus and Baical EM1+Biohumus) and control with 3 replicates and total of 12 lots were prepared.During vegetation period morphological measurements and physiological analyses were carried out in three times as in the beginnig of the vegetation and flowering and the end of the vegetation. In order to determine the effects on soil, samples were taken out from two different experimental areas in 2007 and soil analysis was carried out.Consequently, those natural substances had positive influence on the growth, development and adaptation capabilities of Amaranthus species. However, it was found that sole application of Baical EM1 affected more than Biohumus and there was no considerable difference between Baical EM1+Biohumus and Baical EM1.
