Abstract

Biochar-based fertiliser (BF) is beneficial to improve yield and quality, but the effect of BF on open field tomato remains unclear, especially in karst mountainous areas. The objective of this study was to identify the application effect and optimum application rate of BF. A field experiment was carried out in Southwestern China from 2019 to 2020 to study the effects of different application amounts of BF on the yield, quality, nutrients accumulation and fertiliser utilisation of open field tomatoes. The results showed that compared with the traditional fertilisation practice, BF can significantly increase the yield of open field tomato by 5-9% (2019) and 12-23% (2020), and significantly reduce nitrate content and increase vitamin C content of fruits. Meanwhile, nutrient accumulations, agronomic efficiency, and recovery efficiency of BF treatments were all significantly improved. In conclusion, the BF rate of 2 326 kg/ha improves yield and fertiliser utilisation in open-field tomatoes and could be recommended for tomato production in karst mountainous areas.
