“…Our results also showed improvement in soil hydro-physical properties under biochar and farm yard manure applied treatments, particularly when applied in combination. It was found consistent with several studies reporting better hydro-physical properties under organically amended soils (Ajayi et al 2016;Faloye et al 2019). Presence of intrapores providing higher surface area and permeability for the water and air as well as higher carbon content may lead to the improvement in soil hydro-physical properties.…”

“…Soil micropores present in the fine-textured soils, such as silty loam soil in the present study, hold cohesive forces to attract the water molecules, and thus, improve soil WHC (Ali et al 2017). However, studies reported poor improvement or sometimes decrease in WHC under fine-textured soils due to blockage of pores by the fine particles of biochar (Faloye et al 2019). Lower WFPS observed in sole biochar whereas higher under farm yard manure applied treatment in our study, support this assumption.…”

“…In addition, declining soil fertility caused by injudicious application of chemical fertilizers is also a major concern for the agricultural systems, especially in arid and semi-arid regions of the world (Rockström et al 2010;Ray et al 2013). Several studies recently recommended to identify some agricultural practices having capability for improving the nutrient and water use efficiency, as well as reducing greenhouse gaseous (GHG) emissions without compromising crop yield (Faloye et al 2019;Ramlow et al 2019). In a nutshell, there is a strong need to produce more crops per drop of water for developing sustainable agricultural systems.…”

“…Improvement in soil quality by enhancing soil organic matter (SOM) is considered as a potential strategy for improving crop WP (Faloye et al 2019). Previous studies encouraged the role of organic amendments for improving soil quality and crop productivity in different regions of the world (Srivastava et al 2016;Ramzani et al 2017).…”

“…The International Biochar Initiative (IBI) defined biochar as "a solid material obtained from the thermochemical conversion of biomass in an oxygen-limited environment" (IBI 2012). In addition to its role in soil C sequestration, improving soil quality and crop yields, researchers reported improvement in soil hydro-physical properties such as water holding capacity (WHC) (Van Zwieten et al 2010;Agegnehu et al 2016;Faloye et al 2019;Fischer et al 2019), due to modification of some of the soil physical properties such as porosity, texture, structure, and aggregate stability under biochar applied soils (Atkinson et al 2010;Ajayi et al 2016;Ramzani et al 2017). Results of a meta-analysis revealed an increase in crop productivity by 10% after biochar application (Jeffery et al 2011); however, the crop response varies from negative to positive depending on the biochar characteristics, way of application, and the background soil conditions (Agbna et al 2017;Chen et al 2019).…”

Impact of sole and combined application of biochar, organic and chemical fertilizers on wheat crop yield and water productivity in a dry tropical agro-ecosystem

Agriculture under changing climate scenario is facing major challenges of water scarcity and resource imbalances. Crop water productivity (WP) may act as an indicator of crop responses to water limitation. Organic amendments such as biochar and manure application to soil are suggested for improving soil quality and reducing water requirements from agricultural sector. However, studies exploring the impact of biochar as sole or in combination with organic and/or chemical fertilizers on WP in dry tropical agro-ecosystems are limited. In this study, we observed the effect of rice-husk ash (RHA, biochar) along with farmyard manure (FYM) and chemical fertilizers (CF) under varying water conditions on soil hydro-physical properties, yield and WP of wheat crop. Water-filled pore space (WFPS), grain and straw yield, irrigation and total water productivity varied significantly (at P < 0.001) at treatment level. Grain and straw yield were found higher under sole and combined CF applied treatments. Sole and combined RHA and FYM amendment improved water holding capacity (WHC) and WFPS, whereas a decrease in crop yield was observed as compared to the control. Irrigation and total water productivity were found higher under combined RHA + FYM and sole CF treatments with reduced water supply (except sole CF) as compared to control and sole RHA treatments with full water irrigation. Crop water productivity was found positively correlated with grain and straw yields, however, significant correlations were not observed with WHC and WFPS. Results indicate that increasing soil hydro-physical properties in silty-loam soil may hinder crop yield and WP under sole biochar applied soils. Overall, the implications of the study would help in devising agro-management practices based on combined application of RHA and FYM with reduced chemical fertilizer and water inputs to mitigate the impacts of climate change without compromising crop yield in the highly vulnerable dry tropical agro-ecosystem of India. Moreover, long-term studies are needed in these ecosystems to identify the appropriate agricultural package for mitigating the forthcoming water scarcity conditions.

To investigate the effects of various biochar application levels on the growth physiology and water use efficiency of dry direct‐seeded rice (DDSR) in the black soil region of north‐east China, five biochar application treatments consisting of 2% (BC1), 4% (BC2), 6% (BC3), 8% (BC4) and 10% (BC5) were set, and no biochar application was used as the control treatment (CK). The differences in photosynthetic properties, dry matter accumulation characteristics, water consumption pattern, yield and water use efficiency of DDSR under different biochar application levels were compared and analysed, and the effect of the water use efficiency of leaves (WUEL) at each growth stage on the water use efficiency of yield (WUEy) was also investigated. The results showed that the photosynthetic properties, dry matter accumulation and water consumption of rice increased and then decreased with increasing biochar application level. Compared with CK, the rice yield increased by 1.6%–52% with biochar application, and the 4% biochar application level showed the most significant increase in rice yield (P < 0.05). The WUEy in the BC2, BC3, BC4, BC1, CK and BC5 treatments gradually decreased in that order. Among the WUEy values, significant increases of 27%, 13% and 8% in the BC2, BC3 and BC4 treatments, respectively, compared with the CK were observed (P < 0.05). The effect of WUEL at the prophase tiller, late tiller and milk ripening stages on WUEy enhancement was significant.
