“…The plant height increased significantly when the biochar rate was 6000 kg ha -1 . This result is consistent with previous studies (Chen and Du 2015;Minhas et al 2020). However, when the biochar rate was 9000 kg ha -1 , the plant height decreased significantly compared with no biochar application.…”

Tobacco stalks the main agricultural waste after tobacco harvest, are generally discarded directly or returned to the field after burning. They are rarely processed into biochar, a product that could benefit soil properties. To explore the effects of applying tobacco stalk biochar on soil fertility and tobacco production, tobacco was grown at six biochar application levels (0, 3,000, 4,500, 6,000, 9,000 and 12,000 kg ha-1) in three different sites (Jianchuan, Midu and Eryuan) in Dali County, Yunnan Province. Biochar decreased soil bulk density, increased large and small soil aggregate proportion, and increased soil organic carbon and nitrogen stocks. Biochar also improved the yield and quality of tobacco leaves at all sites. Biochar rates of 3,000, 4,500 and 6,000 kg ha-1 linearly improved soil fertility and agronomic traits while application rate of biochar exceeding 9,000 kg ha-1reduced plant growth. Moreover, the optimum biochar application rates for better plant height, stem diameter, maximum leaf length and leaf width, yield, and average price differed by site. These rates were: 6,000 kg ha-1(Midu), 3,000 kg ha-1(Eryuan) and4,500 kg ha-1(Jianchuan), respectively. In conclusion, appropriate application of biochar could improve soil nutrients and contribute to tobacco growth in different soil nutrient conditions.© 2021 Friends Science Publishers

“…However, studies have shown that improper N application can cause N loss through soil mineralization, ammonia volatilization, and leaching etc. (Resham et al 2016;Qian et al 2018;Minhas et al 2020). Over dosing of N can cause potential pollution risks to soil, groundwater, and other environmental factors (Babar et al 2014;Nan et al 2015).…”

The effects of reducing N fertilizer use on soil NO3--N content and cotton yield were studied through a three-year (2015 to 2017) field experiment in South Xinjiang of China. Cotton was sown under drip irrigation system using five N fertilizer reduction treatments as: conventional N application rate (N100), N application rate reduced by 16.67% (N-16.67), 33.33% (N-33.33), 50% (N-50), and 100% (N-100). The data were recorded for changes in soil NO3--N content, and the SPAD value of cotton leaves was recorded at the peak bolling stage. The total N content of the plant was recorded at the boll formation stage, while yield was recorded at maturity. The results revealed that the soil NO3--N content in N-16.67, N-33.33, N-50, and N-100 treatments decreased by 10.8, 45.5, 60.7 and 72.3% compared to N100 treatment, respectively. The SPAD values of N-16.67 and N-33.33 treatments were significantly higher than those of N100 treatment, while the SPAD values of N-50 and N-100 treatments were significantly decreased. The total N content of cotton was significantly decreased with the increase in the proportion of N fertilizer reduced. The seed cotton yield in N-16.67 and N-33.33 treatments increased by 9.2 and 7.9% compared to the N100 treatment, respectively. However, the cotton yield decreased significantly when the N application rate was reduced by 50 and 100%. The relationship between the N fertilizer reduction rate and cotton yield suggested that the N application rate can be reduced by 18.47–45.50% without compromising the cotton yield in South Xinjiang of China. © 2021 Friends Science Publishers

“…Various management practices play an important role in improving the ability of soils to withhold water and nutrients for optimum plant growth. Soil amendment with biochar (product obtained from pyrolysis of agricultural materials) has found to be a sustainable organic additive to sequester carbon from environment, enhanced moisture holding capacity, and improved soil health and quality by improving cation exchange capacity organic matter status and soil fertility by nutrient retention and stimulating microbial activities in soil (Zheng et al 2010;Minhas et al 2020). The physio-chemical changes of soil due to incorporation of biochar are dependent on biochar nature, its porosity, pyrolysis conditions, application methods and applied rates (Omondi et al 2016;Yu et al 2017).…”

Maize (Zea mays L.) is one of the most important food and feed cereals of the world, but its production is threatened by sudden climate change especially drought. While, low organic matter in soils increases the drought severity. Therefore, study was planned to investigate the interactive effect of biochar and silicon (Si) nutrition on morpho-physiological and biochemical traits under water-deficit environment. Drought stress was applied subsequent 15 days of seedlings development. Experimental treatments comprised of CK (controlled soil no drought stress nor amended), only drought (40% water holding capacity (WHC)), drought + Si (40% WHC with 100 mg Si kg −1 soil), drought + biochar (40% WHC with 4 t ha −1), and drought + Si + biochar (40% WHC + 100 mg Si kg −1 soil +4 t ha −1). Data were collected after 15 days of treatment application. Drought reduced the growth of maize seedlings by reducing shoot biomass (38%), seedling weight (37%), photosynthetic rate (29%), transpiration rate (28.7%), and relative water contents (23.8%) and increased the activities CAT (30%), SOD (38.5%), and POD (33%). The positive effect of sole application of biochar and silicon was observed in improving physio-biochemical traits. In addition, better results were obtained with combined application of biochar and Si in enhancing maize growth such as shoots (25%), roots (40%), and seedlings (27%) as compared with drought. Combined application of biochar and Si may be a viable option to alleviate adversities of drought stress for maize growth and development.
