Effects of Different Organic Extracts on Seed Germination of Some Carrot (Daucus carota L.) Cultivars

Abstract

Climate change and use of intensive chemical input, which are the most important problems of nowadays, cause many biotic and abiotic stresses in plants. For this reason, efforts to develop sustainable approaches, aims to reduce the stress factors to the least, improve productivity and quality, have become notable. Unlike chemical fertilizers, organic preparations such as seaweed extract and microbial fertilizers that dissolve in soil without harming the environment play an important role in increasing the yield and quality of plants. In this context in order to increase the emergence rates and to provide a homogenous and healthy germination, 2 different carrot (Daucus carota L.) cultivars’ seeds were treated
for 12 hours by using 3 different doses of seaweed extract and microbial fertilizers. In the study, germination percentages of seeds, cotyledon occurrences, leaf emergences, root lengths and numbers were evaluated and recorded. In terms of seed germination the use of 1,0 ml/l microbial fertilizers accelerated germination. It was also found that treatment with 0,25 g/l seaweed extract had a vigorous seedling development.
