The Effects of Solid and Liquid Earthworm Fertilizer Doses on The Nutrient Content of Narcissus Cv. "royal Connection" Plant of Grown in Ecological Conditions of Siirt Province, Turkey

Abstract

Today, an important problem is the conversion of organic wastes into vermicompost and alternative organic fertilizer is obtained which is beneficial to sustain the productivity of the soil. Vermicompost is fertilizer material rich in symbiotic, asymbiotic microorganisms, mycorrhizal fungi and actinomycetes, as well as worm secretions, growth hormones, enzymes, vitamins and amino acids. Vermicompost increases the population of beneficial organism in the soil by using these beneficial properties in plant growth and suppresses diseases and harmful effects and provides positive changes in physical, chemical and biological parameters of soil and provides significant improvements in plant growth and yield and nutrient uptake. This study was conducted in order to examine the effects of solid and liquid earthworm fertilizer dosages on nutrients uptaking of Narcissus cv. 'Royal Connection' plant in the Siirt University in 2016-2017 in the ecological conditions of Siirt province. The 25, 50 and 100 g (S1, S2 and S3) for solid fertilizer and; 0.5%; 1% and 2% (L1, L2 and L3) for liquid fertilizer was applied on each bulb. In the study, some nutrients in leaves and bulbs were analyzed. The mean values of N, P, K, Ca, Mg, Fe, Mn, Zn and Cu contents belong to Narcissus bulbs are varied between 1.633-2.013%, 2.787-4.195%, 0.631-0.795%, 0.366-0.866% (p<0.01), 0.096-0.162% (p<0.05), 179.265-399.063 mg kg(-1) (p<0.01), 14.620-16.674 mg kg(-1); 155.697-461.033 mg kg(-1) (p<0.01), and 30.333-45.799 mg kg(-1), respectively.
