Effects of Vermicompost and Liquid Biogas Fertilizer Application on Plant Nutrition of Grapevine (Vitis vinifera L.)

Abstract

In this study the effects of vermicompost and liquid biogas fertilizer applications (Eco Fertilizer and Vermis Vermicompost) were investigated, which are important organic compounds under Tekirdag climate conditions, on some nutrient content of grapevine (Vitis vinifera L.) seedlings. BS (biogas liquid fertilizer) and SS (irrigation water) were used for the irrigation of the saplings in certain periods. This research was designed to clean-up through an environmentally friendly techniques. According to the soil and plant analysis results obtained, the soils were determined as clay loam texture, slightly alkaline, salt-free, low in lime and calcareous. In terms of plant nutrients, positive increases were observed in N, P, Ca, Mg, Fe, Cu elements especially in BS applications with increasing doses of vermicompost. N values determined in the average plant nutrient contents of the applications varied between 1.89-2.64% and the highest value was obtained from BS application with 2.64% of vermicompost application in the 3rd trial (VC(3)MG(0)). Phosphorus also reached the highest value with 0.30% in the BS application of the 3rd trial (VC(3)MG(0)), and the highest nutrient content in the calcium element was detected as 2.80% in the BS application (VC(1.5)MG(0.75)) of the 6th trial. It was observed that the increasing vermicompost dose increased the Fe ratio in the leaf by 175 mg kg(-1) above the limit value. In general, the average nutrient values of the areas where irrigation water (SS) was applied were found to be 11.2-34.1% lower than the biogas liquid waste fertilizer (BS) applications. It was observed that the plant nutrient contents of the fertilizer applications were statistically significant (P <= 0.05). It has been determined that it has no significant effect on K element.
