“…The average dry mass of root, stem, leaf, and fruit; Y; and WUE increased with increasing biochar application. Biochar can promote plant height and leaf growth and significantly increase aboveground dry matter [49,50] . Zhang et al [51] also showed that biochar application can promote the absorption capacity of tomato plants to nutrients and improve tomato yield.…”

Tomato (Solanum lycopersicum L.) production was threatened by the inefficiency of fertilizers, contributing to the deterioration of the soil environment under greenhouse conditions in southern China. Biochar application could ameliorate the physical properties of soil and enhance the growth and productivity of tomatoes. In this study, a pot experiment was conducted with four biochar addition rates of 0% (BA 0 ), 1% (BA 1 ), 3% (BA 3 ), and 5% (BA 5 ). Results showed that the soil physical properties, morph-physiological indicators, yield, and water use efficiency (WUE) of tomatoes with biochar addition were significantly higher than those of tomatoes without biochar addition. Among the different treatments, BA 5 provided the highest total porosity (53.09%), field capacity (40.73%), plant height (72.5 cm), net photosynthetic rate (16.04 mmol/m 2 •s), total dry matter (184.65 g/plant), yield (54.9 t/hm 2 ), and WUE (38.5 kg/m 3 ). The yield and WUE increased from 44.5 t/hm 2 and 31.2 kg/m 3 under BA 0 , respectively, to 54.9 t/hm 2 and 38.5 kg/m 3 under BA 5 , respectively. The results suggest that BA 5 can maximize improvements in soil physical properties to augment plant growth, thereby increasing the yield and WUE of tomatoes. However, the effects of BA 3 and BA 5 on WUE were not significantly different. Thus, from the perspective of economic investment, BA 3 is recommended.

“…Pod pepper holds a vital place among economic crops, as it is not only the largest vegetable crop in terms of planting area and production value in southwest China, but also boasts a high nutritional value [31,32]. Numerous field experiments have demonstrated that supplementing chemical fertilizers with biochar can enhance crop yield and soil nutrient levels.…”

Biochar is frequently utilized as a helpful amendment to sustain agricultural productivity. However, it remains uncertain whether biochar can effectively replace chemical fertilizers, especially in karst regions. To investigate the effects of co-applying biochar and chemical fertilizer on the biological characteristics and fertilizer uptake of pod peppers, as well as to determine the optimal ratio of biochar to chemical fertilizers, a two-year field experiment was conducted in southwest China. The results showed that, compared to the locally typical chemical fertilizer treatment (CF), the combined application of biochar and chemical fertilizer significantly increased the yield of both fresh and dry pod pepper. Chemical fertilizer reduction and biochar application also ameliorated fruit quality, increased nutrient accumulation, and improved fertilizer utilization efficiency. What is more, although the employment of biochar made production costs higher, the reduction in chemical fertilizers and the increase in yield improved economic efficiency, especially in the CF70B treatment (70%CF + biochar). In conclusion, moderate amounts of biochar instead of chemical fertilizers may be a valid nutrient management strategy for pod pepper in the karst mountain areas, which is beneficial for maintaining yield stability, improving quality, and increasing net income.

“…At present, organic remediation materials have received much attention as widely used soil amendments because of their beneficial effects in enhancing crop yield and quality and improving soil quality. Many studies have confirmed that organic remediation materials can overcome or mitigate the barriers to continuous cropping by increasing organic carbon sources and soil microbial diversity ( Su et al., 2022 ; Zhang et al., 2022a ; Zhang et al., 2022b ).…”

Recently, biochar (B) and vermicompost (V) have been widely used as amendments to improve crop productivity and soil quality. However, the ameliorative effects of biochar and vermicompost on the continuous cropping of pepper under open-air conditions, particularly in the karst areas of southwestern China, remain unclear. A field experiment was conducted to study the effects of biochar and vermicompost application, alone or in combination, on the yield, quality, nutrient accumulation, fertilizer utilization, and economic benefits of continuous pepper cropping from 2021 to 2022. The experiment included six treatments: CK (no fertilizer), TF (traditional fertilization of local farmers), TFB (TF combined with biochar of 3000 kg·ha-1), TFV (TF combined with vermicompost of 3000 kg·ha-1), TFBV1 (TF combined with biochar of 1500 kg·ha-1 and vermicompost of 1500 kg·ha-1), and TFBV2 (TF combined with biochar of 3000 kg·ha-1 and vermicompost of 3000 kg·ha-1). Compared with the TF treatment, biochar and vermicompost application alone or in combination increased the yield of fresh pod pepper by 24.38–50.03% and 31.61–88.92% in 2021 and 2022, respectively, whereas the yield of dry pod pepper increased by 14.69–40.63% and 21.44–73.29% in 2021 and 2022, respectively. The application of biochar and vermicompost reduced the nitrate content and increased the vitamin C (VC) and soluble sugar content of the fruits, which is beneficial for improving their quality. Biochar and vermicompost application alone or in combination not only increased nutrient uptake but also significantly improved agronomic efficiency (AE) and recovery efficiency (RE). In addition, although the application of biochar or vermicompost increased production costs, the increase in yield improved net income (ranging from 0.77 to 22.34% in 2021 and 8.82 to 59.96% in 2022), particularly in the TFBV2 treatment. In conclusion, the use of biochar and vermicompost amendments had a positive effect on the productivity and economic benefits of continuous pepper cropping, and the co-application of biochar and vermicompost could be an effective nutrient management strategy for the continuous cropping of pepper in the karst mountain areas of southwest China.
