THE IMPACTS OF THE BIOCHAR ADDITION IN DIFFERENT DOSES ON YIELD AND NUTRIENT UPTAKE OF THE CHICKPEA PLANT (CICER ARIETINUM L.) UNDER THE CONDITIONS WITH AND WITHOUT INCUBATION

Abstract

Biochar which is intensively used in the issue of the struggle against global warming in recent years also enhances the physical, chemical and biological properties of the soil when it is added to the soil. With this study; the impact of the biochar applications (0%, 0.5%, 1%, 2%, 3%, 4% and 5% (v/v)) in different doses under the conditions with and without incubation on the yield of the chickpea plant and nutrient concentrations has been examined. The study has been carried out with three repetitions according to the experimental pattern of randomized blocks in the plastic pots with the capacity of 3 kg under the greenhouse conditions. The addition of biochar was made 60 days before the plantation of the herbs to the pots with incubation and watering has been made with pure water for 60 days. The dry matter production and nutrient concentrations have been determined in the plants harvested in the broad bean bonding period. The results of the study have shown that the application that increases the dry matter production of the chickpea plant most is the application of 3% biochar dose under the conditions with incubation (10.02 g pot(-1)). In addition; the biochar applications have decreased the uptake of other nutrient except for K and Zn under both the conditions with and without incubation. While 3% biochar application under the conditions with incubation and 4% biochar application without incubation have been the applications having the most significant impact on the Zn concentration of the chickpea plant respectively with 67.2 mg Zn kg(-1) and 60.5 mg Zn kg(-1), 2% biochar application has been the application which has had the most significant impact on the K concentration of the chickpea with respectively 2.81% K and 2.37% K under the conditions both with and without incubation. In addition; when the general averages in the study have been assessed, it has been determined that the biochar applications have more impact on the dry matter production of the chickpea plant and the concentrations of N, P, K, Zn and Mn according to the conditions without incubation.
