Experiment Title Effect of Deficit Irrigation and Biochar amendment on the growth, yield and quality of Brinjal
Research Type Departmental Research
Experiment Background The intensity of water resource limitations and the frequency of droughts will probably increase in the context of global climate change. Consequently, this is expected to adversely affect crop production. To address this problem, water use efficiency (WUE) must improve. This will help to sustain the water resources that are available for agriculture. In order to achieve this, different innovative irrigation strategies have been developed and assessed. One such technique is deficit irrigation (DI), which is an optimization approach that improves soil water exploitation by plant roots. Brinjal is considered to be one of the more popular vegetables, with an extensive local market distribution and superior economic value. Biochar is biomass that has been pyrolyzed in a low oxygen environment, and has the potential ability to improve soil fertility and enhance crop productivity. Many studies have been carried out around the world, with the objective of investigating the effects that biochar applications to soils would have on crops yields. The majority of the studies reported that biochar amendment (BA) has improved soil quality, structure, and nutrient availability, as well as plant productivity. Furthermore, research has found that BA improves crop productivity and mitigates drought, salinity, acidity, and toxic metal stresses that are commonly associated with plant stress (Fiaz et al., 2014; Thomas et al., 2013). Recently, there has been an increase in the use of integrated approaches to soil management in order to improve crop production by confronting the problems of drought conditions, nutrient-poor soils, salinization, and other forms of soil degradation. Present study aimed to study the effect of deficit irrigation with biochar amendment
