“…[90], and Raiesi and Kabiri [91], found an increase in urease activity in NT compared to CT, which supports the findings in this study. The increase in urease activity under 30% residue retention in this study, support previous findings by Ji et al [92], Zhang et al [93], and Saikia and Sharma [94], who found residue retention to be crucial in improving urease activity. Increased urease activities might be due to improved soil organic carbon, organic nitrogen, and biological activity [28] after NT and residue retention.…”

Questions on sustainable and appropriate cropping systems for bioenergy sweet sorghum in the smallholder farming sector still exist. Therefore, a short-term experiment was carried out to study the influence of management on microbial biomass carbon (MBC), β-glucosidase, acid phosphatase, and urease activities in a sweet sorghum cropping system in South Africa. Tillage [no-till (NT) and conventional tillage (CT)], rotation [sorghumvetch-sorghum (S-V-S) and sorghum-fallow-sorghum (S-F-S)] and residue retention [0%, 15% and 30%] were evaluated. TillageÂ rotationÂ residue management interaction influenced (P < 0.05) MBC whilst crop rotation residue influenced (P < 0.05) β-glucosidase. Tillage affected β-glucosidase (P < 0.05), acid phosphatase (P < 0.001), and urease enzyme (P < 0.01) while crop rotation only influenced acid phosphatase (P < 0.01). Residue retention affected acid phosphatase (P < 0.001) and urease enzyme (P < 0.001). NT þ S-V-Sþ30% interaction resulted in the highest MBC content compared to CT þ S-F-Sþ0%. NTþ30% enhanced β-glucosidase activity, S-V-S enhanced acid phosphatase compared to S-F-S. MBC and enzyme activities were positively correlated with each other. Tillage and residue management were the main factors influencing soil biological indicators under bioenergy sweet sorghum in South African marginal soils in the short-term. Soil biological indicators were higher under NT and 30% residue retention respectively. NT þ S-V-Sþ30% was a better treatment combination to enhance soil quality under bioenergy sweet sorghum in South African marginal soils.

“…These factors collectively may have promoted better root growth, ultimately leading to significant increase in plant growth. Similar outcomes were documented by Anjum et al [3] and Karki et al [4], Memon et al [1] reinforcing the validity of these findings. Among different nitrogen levels, higher nitrogen application of 125% N was consistently linked to increased plant height at all growth stages i.e., six leaf, silking, dough and physiological maturity with 56, 196, 206, 219 cm respectively.…”

A field experiment was conducted in sandy loam soils of Agricultural Research Station, Karimnagar during Rabi, 2022 in a split-plot design with three replications. Main plots includes three tillage practices viz., Zero tillage, Reduced tillage and Conventional tillage and sub plots includes three nitrogen levels viz., 75 %N, 100%N and 125%N. The results revealed that, maize cultivation under conventional tillage recorded significantly higher grain yield (8324 kg ha-1) which is statistically on par with reduced tillage treatment (7775 kg ha-1). In turn reduced tillage was statistically comparable to zero-tillage treatment (7353kg ha-1). Among different nitrogen levels examined, maize sown with 125% N application achieved significantly highest grain yield (8055 kg ha-1). This yield was statistically comparable to grain yield observed with 100% N application (7896 kg ha-1). While, significantly lowest grain yield (7501 kg ha-1) was recorded with 75% N application. Significantly highest grain yield in conventional tillage which is statistically on par with reduced tillage and among nitrogen levels, highest grain yield with 125%N which is on par with 100% N may attributed to increase in crop growth parameters viz., plant height, leaf area index and higher yield attributes viz., cob length and diameter, kernel rows number. The study concludes that maize cultivation with conventional tillage or reduced tillage results in higher grain yield. Concerning different nitrogen levels, higher grain and economic yield was obtained with 100% N application.

“…These results are consistent with the results of Parihar et al, (2016) that performed a long term (field) experiment with different tillage practices and intensive use of crop rotation and reported higher Dha in ZT than CT in legume based crop rotation. The same findings were obtained by Madejón et al (2007) and in rainfed conditions by Kumar et al(2017).A review paper of 68 studies showed that residue retention and reduction in tillage intensity significantly improved soil Dha enzyme (Saikia and Sharma, 2017). The same was proven by the results of Wang et al(2012) and Panettieri et al(2013).The decomposition (residue) may release some nutrients (like nitrogen, phosphorus, and sulfur) necessary for plant and microbial growth (Jat et al, 2015).…”

Conservation tillage and carbon sequestration are critical issues in rain-fed farming areas of Pakistan. Conservation tillage is not extensively used in developing countries on dryland soil where marginal farming is practiced. Therefore, primary purpose of this experiment was to determine the influence of conservation tillage practices on soil organic carbon (SOC), particulate organic matter (POC), mineral associated organic carbon (MOC), microbial biomass carbon (MBC) and dehydrogenase activity (Dha) in loess dry land Pothwar, Punjab, Pakistan. The tillage practices included zero tillage (ZT), minimum tillage (MT), reduced tillage (RT) and conventional tillage (CT) with mouldboardplough as a control in main plot and fallow-wheat (Triticumaestivum L.) and mungbean (Vigna radiate L.) crop rotation in sub plot as a split plot layout. The results indicated that ZT showed higher SOC (7.90 g kg -1 ), POC (2.35 g kg -1 ), MOC (5.1 g kg -1 ), MBC (359.37 μgg -1 ) and Dha (45.12 TPFμgg -1 dry weight) than CT. Among crop rotation, overall mungbean-wheat showed higher values as compared to fallow-wheat crop. The study indicated that conservation tillage practices with legume crop rotation have potential for improving soil organic carbon storage and hence carbon sequestration in soil.
