“…The higher concentrations of N and Mg in hardwood biochar compared to softwood biochar may have resulted in greater Chl SPAD values for hardwood biochar at most of the measurement days. Although we did not measure the nutrient concentration in the leaves, chlorophyll concentration is closely correlated with the N concentration and used as a tool to determine the N status of the plants (Oppong Danso et al, 2020).…”

The integration of biochar and deficit irrigation is increasingly being evaluated as a water-saving strategy to minimize crop yield losses under reduced irrigation in arid and semi-arid regions such as West Texas. A 2-year (2019 and 2020) open-field study evaluated the effect of two types of biochar amendments (hardwood and softwood) and three irrigation rates [100, 70, and 40% crop evapotranspiration (ETc) replacement] on the physiology, plant growth, and yield of sweet corn in semi-arid West Texas. All experimental units were replicated four times in a split-plot design. The chlorophyll content (ChlSPAD) in 40% ETc dropped significantly compared to 100% ETc and 70% ETc during the reproductive phase. Although water stress under 40% ETc decreased photosynthesis (Pn) to limit transpiration (E) by stomatal closure, it improved intrinsic water use efficiency (iWUE). The above-mentioned gas exchange parameters were comparable between 100% ETc and 70% ETc. Both biochar treatments increased ChlSPAD content over non-amended plots, however, their effect on gas exchange parameters was non-significant. All growth and yield-related parameters were comparable between 100% ETc and 70% ETc, but significantly greater than 40% ETc, except water productivity (WP). Both deficit irrigation treatments improved WP over full irrigation in 2019, but in 2020, the WP gains were observed only under 70% ETc. Hardwood biochar decreased soil bulk density and increased soil porosity, but it had a marginal effect on the water retention characteristics. These results suggest that 70% ETc can be used as an alternative to full irrigation to save water with a minimal yield penalty for sweet corn production in the West Texas region. The hardwood biochar application improved the vegetative biomass significantly but yield marginally during the first 2 years of application. A long-term study is required to test the effect of biochar under deficit irrigation beyond 2 years.

“…However, the properties of biochar are closely related to its physical and chemical properties. In recent times, biochar has been developed to improve crop production as an environmentally friendly solution to reduce water scarcity problems (Oppong Danso et al, 2020).…”

The global approach in agriculture is to reduce the use of chemical fertilizers and the supply of nutrients from available sources which are environmentally friendly. In order to evaluate the feasibility of tobacco products without chemical fertilizer inputs, this research was carried out as a factorial experiment based on a 3×2×2 randomized complete block design which included biochar applied at three levels (0, 4, and 8 t ha -1 ), mycorrhiza, and Azotobacter at two levels (with and without application) with four replications. According to the results, 4 t ha -1 biochar increased the dry yield by 22%, the relative water content by 6%, and the root length by 41% compared to the zero level. However, there was no statistically significant difference between the 4 and 8 t ha -1 application of biochar with regard to most traits. The application of mycorrhiza improved the leaf area index as well as the tobacco root length. Azotobacter significantly increased the root length and nicotine content. The tobacco yield in rain-fed conditions is lower than usual, therefore the combined use of biochar and these biofertilizers may be considered as a viable solution. With increasing interest in the use of environmentally friendly sources of fertilizers and in terms of economic considerations, the use of 4 t ha -1 of biochar along with mycorrhiza and Azotobacter achieved an acceptable yield.K e y w o r d s: bio-coal, biofertilizers, chemical quality, nicotine content, tobacco

“…Tanure et al (2019) verificaram que altas doses de biochar de casca de eucalipto (40 e 60 g kg -1 ) promoveram uma melhoria no desenvolvimento, atividades fisiológicas e estado nutricional das plantas de milho submetidas a diferentes condições de umidade do solo. Da mesma forma, Danso et al (2019), estudaram o potencial do uso do biochar em solos degradados no cultivo do milho sob irrigação deficitária. Os resultados encontrados foram semelhantes ao cultivo sob irrigação plena.…”
