Effects of seaweed extract and arbuscular mycorrhiza co-application on yield components of Brassica oleracea var botrytis L.
Abstract
In cauliflower cultivation, in order to obtain more crops, high amounts of chemical fertilizers are used, neglecting soil health and food safety problems. As a result of excessive use of chemical fertilizers in agriculture, the physical, biological and chemical structure of the soil deteriorates over time and the crop yield and quality decrease over time. In the study applied in a randomized block design with four replications, the effects of Arbuscular Mycorrhizal Fungi (AMF), increased seaweed (DY) and 30% reduced chemical fertilizer (7/10KG) on plant yield were investigated. In the trial; plant crown length, crown diameter, stem diameter, stem length, crown weight, marketable yield, number of leaves, leaf length, leaf diameter and some nutrient element contents in the leaves were measured. According to the measurements made in the study; There was an increase in yield due to the increase in seaweed doses. Yield components obtained from single (AMF, KG and control) applications were lower compared to the values obtained from 200 ml/100 L water + AMF +7/10KG and 400 ml/100 L water + AMF + 7/10 KG combinations. The highest values among the applications were obtained from 200ml/100Lwater + AMF +7/10KG and 400ml/100Lwater + AMF +7/10KG combinations at the same significance level. Applications with the highest values increased by 25.6% in plant crown length, 37.3% in plant crown diameter, 17.5% in plant stem diameter, 57.4% in stem length, 75% in crown weight, 80.7% in marketable yield, 33% in leaf length, and 55.5% in leaf diameter compared to control application. Combined application of SWE and AMF increased leaf N, P and K contents by 48.4%, 33.3% and 34.6%, respectively. It also provided significant increases in Ca, Mg, Fe, Zn and Mn contents. According to these results; By applying DY and AMF together, chemical fertilizer doses can be reduced by 30% and in this case, an improvement in growth, yield and nutrient content can be achieved in cauliflower.
