“…Under different tillage practices, increasing N rates significantly increased the number of bolls per plant [38,52]. However, opposite findings were reported by Afzal [53], N application under different planting densities did not influence the lint weight and fiber quality.…”

Long-term conservation tillage and straw incorporation are reported to improve the soil health, growth, and yield traits of crops; however, little is known regarding the optimal nitrogen (N) supply under conservation tillage with straw incorporation. The present study evaluated the effects of conservation tillage practices (ZTsas: zero tillage plus wheat straw on the soil surface as such, and MTsi: minimum tillage plus wheat straw incorporated) and different N application rates (50, 100, 150, and 200 kg ha−1) on the yield and quality traits of cotton and soil characteristics in a five-year field experiment. The results showed that ZTsas produced a higher number of bolls per plant, boll weight, seed cotton yield, 100-seed weight, ginning out-turn (GOT), fiber length, and strength than MTsi. Among different N application rates, the maximum number of bolls per plant, boll weight, seed cotton yield, GOT, 100-seed weight, fiber length, strength, and micronaire were recorded at 150 kg N ha−1. Averaged over the years, tillage × N revealed that ZTsas had a higher boll number plant−1, boll weight, 100-seed weight, GOT, fiber length, and strength with N application at 150 kg ha−1, as compared to other tillage systems. Based on the statistical results, there is no significant difference in total soil N and soil organic matter among different N rates. Further, compared to MTsi, ZTsas recorded higher soil organic matter (SOM, 8%), total soil N (TSN, 29%), water-stable aggregates (WSA, 8%), and mean weight diameter (MWD, 28.5%), particularly when the N application of 150 kg ha−1. The fiber fineness showed that ZTsas had no adverse impact on fiber fineness compared with MTsi. These results indicate that ZTsas with 150 kg N ha−1 may be the optimum and most sustainable approach to improve cotton yield and soil quality in the wheat–cotton system.

“…The effects of green manures C. cajan, C. juncea and S. guianensis on plant cover, soil protection and improvement of physical properties are described in several studies (Long et al, 2017;Martins, 2018;Melander et al,2020;Soares et al, 2021;Silva et al, 2021;Neto et al, 2021). These authors highlighted that C. cajan, C. juncea and S. guianensis promoted increased fertility and improvements in the aggregate stability index and resistance to root penetration.…”

The objective of this study was to evaluate plant cover and dry mass produced by green manures and their influence on the chemical attributes of soil for the ecological restoration of an area around bauxite mine environment in Southeast Brazil. Soil preparation, chemical fertilization and sowing of three species of green manures were carried out: Cajanus cajan, Crotalaria juncea and Stylosanthes guianensis. In general, C. cajan and C. juncea showed the best performance in plant cover. C. cajan and S. guianensis produced more phytomass. Green manures were efficient to promote rapid plant cover and increase in soil organic matter and total-N contents in all treatments. Therefore, green manure is a viable alternative that contributes to the success of ecological restoration projects in areas in the bauxite mining environment.

“…Climateresilient and sustainable agricultural management practices can improve soil hydraulic conductivity and water retention in the soil, particularly at the soil-root zone, which are key indicators of soil quality and environmental sustainability, and hence contribute to improve crop productivity and lower water loss (Lal, 2015). Soil physical quality parameters, viz., soil structure, number of pores, and their connectivity and continuity are affected by agricultural management practices such as tillage and crop diversification (Gabriel et al, 2019;Nouri et al, 2019;Kabir et al, 2020;Silva et al, 2021). Changes in soil structure and pore configuration, may not always be evident immediately after the implementation of management practices (Nouri et al, 2019;Silva et al, 2021).…”

This emphasizes the significance of short-term and long-term studies that reveal the full consequences of agricultural management practices for the functionality of the soil pore system.…”
