“…The in-situ surface retention of crop residues as full or anchored also boosts soil health by improving soil physical properties (Das et al, 2021 ; Saurabh et al, 2021 ), soil organic carbon, and labile carbon fractions (Liu et al, 2013 ; Gupta et al, 2022 ); increasing moisture retention; regulating temperature (Fu et al, 2021 ); enhancing nutrient availability (Moharana et al, 2012 ) and root absorption; suppressing weeds (Nikolić et al, 2021 ); decreasing salinity (Prajapat et al, 2020 ); encouraging soil biological activity (Singh et al, 2018 ); and controlling crop pests and diseases (El-Shater and Yigezu, 2021 ). Moreover, crop diversification reduces pressure in current agriculture and maintains or even enhances soil microbial abundance as crop diversification has shown benefits for soil macro- and microorganisms, while maintaining crop yields (Baldwin-Kordick et al, 2022 ; Morugán-Coronado et al, 2022 ; Rai et al, 2022 ).…”

IntroductionConservation agriculture is a sustainable system of farming that safeguard and conserves natural resources besides enhancing crop production. The biological properties of soil are the most sensitive indicator to assess the short term impact of management practices such as tillage and residue incorporation.MethodsNine treatments of tillage and residue management practices [Reduced till direct seeded rice-zero till barley (RTDSR–ZTB); RTDSR–ZTB–green gram residue (Gg); Zero till direct seeded rice–zero till barley–zero till green gram (ZTDSR–ZTB–ZTGg); RTDSR–ZTB + rice residue at 4 t ha 1 (RTDSR–ZTBRR4); RTDSR–ZTBRR6; un-puddled transplanted rice (UPTR)–ZTB–Gg; UPTR–ZTBRR4; UPTR–ZTBRR6, and puddled transplanted rice (PTR)–RTB] executed under fixed plot for five years on crop productivity and soil biological properties under rice-barley production system.ResultsThe shifting in either RTDSR or ZTDSR resulted in yield penalty in rice compared to PTR. The PTR recorded highest pooled grain yield of 3.61 ha−1. The rice grain yield reduced about 10.6% under DSR as compared to PTR. The ZTB along with residue treatments exhibited significantly higher grain yield over ZTB, and the RTDSR-ZTBRR6 registered highest pooled grain yield of barley. The system productivity (12.45 t ha−1) and sustainable yield index (0.87) were highest under UPTR-ZTBRR6. Biological parameters including microbial biomass carbon, soil respiration, microbial enzymes (Alkaline phosphatase, nitrate reductase and peroxidase), fluorescein diacetate hydrolysis, ergosterol, glomalin related soil proteins, microbial population (bacteria, fungi and actinobacteria) were found to be significantly (p < 0.05) effected by different nutrient management practices. Based on the PCA analysis, Fluorescein diacetate hydrolysis, microbial biomass carbon, soil respiration, nitrate reductase and fungi population were the important soil biological parameters indicating soil quality and productivity in present experiment. The results concluded that UPTR-ZTBRR6 was a more suitable practice for maintaining system productivity and soil biological health.DiscussionThe understanding of the impact of different tillage and residue management practices on productivity, soil biological properties and soil quality index under rice-barley cropping system will help in determining the combination of best conservation agriculture practices for improved soil quality and sustainable production.

“…The saline tracks of Indo‐Gangetic Plains are typically rainfed with mono‐cropping in the rainy season (July–October). Low cropping intensity and agricultural diversification during the dry winter limit the options for food and livelihood security (Herrera et al, 2021; Rai et al, 2022). Under given circumstances, use of non‐traditional water resources like treated wastewater and saline groundwater can supplement agricultural water demand (Díaz et al, 2018; Suri et al, 2019).…”

“…But, often, it results in soil salinisation and associated crop loss. In the semi‐arid region, no significant reduction in wheat yield was recorded under deficit saline irrigation (7.5 dS m −1 ) in comparison with irrigation with water of 0.6 dS m −1 (Mosaffa & Sepaskhah, 2019; Rai et al, 2022). Rice straw mulch or crop residue incorporation improves crop productivity and water use efficiency by reducing evaporation losses, moderating soil temperature and improving soil health (Soni et al, 2021).…”

“…Forage sorghum is preferred for kharif season over other crops because of high water use efficiency, low nitrogen demand, high salt, temperature and drought tolerance (Berenguer & Faci, 2001; Casas et al, 2020; Malobane et al, 2018). Conservation tillage in association with mulching improves the overall soil quality by increased soil organic carbon, aggregation and reduced evaporation losses and salt dynamics (Dixit et al, 2019; Mosaddeghi et al, 2009; Mutsamba et al, 2020; Rai et al, 2022). Despite the beneficial effects of mulching, conservation tillage under drought‐prone agro‐ecologies, combined application of tillage, mulching and residual effect of deficit saline water irrigation applied to wheat on forage yield and nutritive value of sorghum grown in succession under saline soils are unknown.…”

Soil and groundwater salinity associated with limited rainfall are the challenges for checking salinity build‐up in semi‐arid regions. This field experiment was conducted to test the impact of deficit saline irrigation (DSI) (in winter) with mulching and tillage on salinity build‐up, yield and nutritive value of rainfed‐forage sorghum. Tillage (reduced, conventional and zero), saline water (8.0 dS m−1) irrigation (100%, 80% and 60% of water requirement [WR] in wheat) and mulch were allocated following split factorial layout. DSI with mulching produced at par wheat and sorghum yield compared with 100WR irrigation with harvested rainwater. Mulching improved wheat grain yield and the soil water content by ~13% throughout the cropping season. Forage sorghum yield was increased by DSI and mulching in the previous season compared with irrigation with 100WR saline water. Reduced tillage declined the neutral detergent fibre (NDF), acid detergent fibre (ADF) and acid detergent lignin (ADL) with an increase in cell soluble constituents. DSI and mulching also increased the digestible nutrient, crude protein (CP), ash and reduced ADF of sorghum. Soil salinity showed a negative correlation with CP, positive correlation with ADF, ADL and cellulose. Therefore, it is recommended that DSI and reduced tillage with mulching can be a reliable option for productive use of saline soils and water by cropping system intensification. These results also showed the potential for achieving 2030 agenda for sustainable development goals as well as targets of land degradation neutrality in salt‐affected soils by savings irrigation, doubling cropping intensity and preventing salinity build‐up.

“…In India, Maharashtra secured the first position in sorghum production (1.76 million tonnes) followed by Karnataka (0.88 million tonnes), Rajasthan (0.59 million tonnes) and Tamil Nadu (0.45 million tonnes) (Praveenkumar et al, 2023). Compared with the global average, sorghum productivity in India is rather low, mostly because the crop is cultivated under rainfed conditions and has undergone unfavourable climatic conditions during the growth stages (Rai et al, 2022). Climate change is a serious concern today and an urgent evolving threat to global food security.…”

Climate change is likely to affect agricultural production in many parts of the world. Sorghum is the stable food crop in semiarid areas, and climate change has significant adverse effects on sorghum yields. The optimum time of sowing is one of the important technologies that allow the crop to better utilise natural resources by the crop to maximise productivity. For optimizing the sowing time, the field investigation was carried out in Tamil Nadu Agricultural University, Coimbatore, under summer irrigated conditions in 2022. The experiment was laid out in a split-plot design with three replications. The main plot consists of five dates of sowing and the subplot includes different nitrogen levels. The results revealed that advanced sowing (first fortnight of April) reduced the yield by 13.73% and delayed sowing (second fortnight of May) recorded the maximum yield (4230.3kg ha-1) with higher phyllochron values. GDD manifested a significant negative relationship with a high correlation coefficient (r) value of -0.98** (p = 0.01) for days to anthesis, -0.98** (p = 0.01) for days to physiological maturity and -0.88* (p = 0.05) for phyllochron. Average temperature exhibited a significant negative correlation with days to anthesis (-0.75*), physiological maturity (-0.97**) and phyllochron (-0.89*). The best-fit regression model showed that a GDD-based model could better predict the phenology of sorghum compared to an average temperature-based model. The study indicated that understanding sorghum's phenological response and productivity level under varied dates of sowing and the nitrogen levels in semiarid environments can help determine the appropriate sowing time and optimum nitrogen level for achieving better yield in summer-irrigated sorghum.
