Effect of chemical and organic fertilisation on yield and macro-micro content of Chickpea (Cicer arietinum L.) cultivars
Abstract
Due to its valuable nutritional content, chickpea is expected to become the most important crop for an increasing global population. Therefore, this research was conducted to investigate the effects of organic (vermicompost, farmyard manure, and chicken manure) and chemical (DAP and NPK+Zn) fertilisers on grain yield and nutrient content in two chickpea varieties (Arda and Botan) during the 2019-2020 growing season. The experiment was organised according to a randomised complete split block design with three replications. Results were expressed as mean values. The application of chicken manure significantly improved yield and yield components. The results showed that the Arda chickpea variety plot, where chicken manure was applied, had the highest yield (3272 kg ha-1), whereas the control plot of the Botan chickpea variety had the lowest yield (2302 kg ha-1). The application of organic fertilizers resulted in significant increases in plant height, 100-grain weight, grain yield, harvest index, and protein ratio. Additionally, there was a significant increase in the concentration of Mg, Na, Zn, Cu, K, and Ca in the grains. Thus, it was concluded that organic fertilizer can be used as a suitable alternative to chemical fertiliser in chickpea cultivation in order to create a sustainable agricultural system, increase productivity, and maintain and improve soil properties. In our country, where fertilizer resources are limited, organic applications to widely cultivated plants such as chickpeas would be extremely beneficial for the economy, environment, and soil structure.
