“…The compaction caused through development of plough pan and higher BD under CT practices enhances the soil resistance which might contribute to higher soil PR in repeated tilled soil (Saha et al, 2010). Similar to tillage practices, inclusion of legumes in intensive maize based rotations resulted into significantly lower soil PR compared to monoculture of maize (Parihar et al, 2016). Unger and Jones, 1998 also reported that the PR differed due to crop rotations, being lower for continuous wheat (1.79 MPa) than for wheat-fallow (2.32 MPa) or wheat-sorghum-fallow (2.42 MPa).…”

“…For example, after longterm adoption tillage practices (24 years) the soil BD was 28.2% higher in CT than ZT (Utomo et al, 2013). Parihar et al, 2016 reported that after adoption of CA practices for seven years, the soil BD lowered by 4.3 to 6.9 % in 0-30 cm soil profile than CT. The decrease in soil BD under CA could be due to higher SOC, better aggregation, increased root growth and biomass (Salem et al, 2015).…”

“…In contrast, greater soil macro-aggregation due to reduced soil disturbance and maintenance of residue cover is important reason for higher aggregate stability with CA practices (Filho et al, 2002). For example, Parihar et al 2016 reported that continuous adoption of CA practices i.e. ZT and Permanent bed (PB) along with residue retention over seven year resulted into 23 to 32.5 % higher water stable aggregates, 47.1 to 53.4 % higher mean weight diameter and 28.5 to 33.9 % higher geometric mean diameter compared to CT in 0-15cm soil depth, respectively.…”

“…However, an another study shows positive effect of the incorporation of legume residues by tillage rather than leaving them on the soil surface, which could result in better contact between soil particles and soil microbes in maize-wheat cropping system (Christopher et al, 2009;Zhao et al, 2012). In, Parihar et al, 2016 reported that inclusion of chickpea and mungbean in intensive maize based rotation attributed significantly higher water stable aggregates, mean weight diameters and geometric mean diameter compared to continual maize and maize succeeding by mustard in rotations under north-western Indo-Gangetic-Plains (IGP) of India. These finding of higher water stable aggregates with inclusion of legume in intensive crop rotations are in close agreement with Six et al, 2002 andBiswas et al, 2009.…”

“…Likewise, Kahlon et al, 2013 andChen et al 2014 found that reduced tillage significantly increased the initial soil infiltration capacity over CT which resulted in higher saturated and unsaturated hydraulic conductivity of the soil as compared to CA. Parihar et al 2016 reported, that after seven year of adoption the saturated conductivity of the a sandy loam soil increased by 14.3 and 11.2 % in PB planting and 11.1 and 12.0 % in ZT in 0-15 and 15-30 cm soil layers, respectively, compared to CT in north western IGP of India. The increase in saturated conductivity under PB and ZT was mainly attributed to decrease in BD and increase in effective pore volume (Rasool et al, 2007;Li et al, 2011) due to better soil aggregation.…”

Ecological benefits associated with plant growth-promoting rhizobacteria (PGPR) inoculants offer a promising integrated nutrient management option to counteract plant nitrogen (N) deficiency. We performed field experiments to evaluate the effect of integrated N fertilizer regime involving chemical N fertilizer (CNF) and N-enriched compost (NEC), either alone or combined with selected PGPR (Pseudomonas aeruginosa) on sunflower seed quality, N use efficiency (NUE) and soil fertility during 2014-2015. We found that integrated N biofertilizer application resulted in significantly higher seed oil concentration, fatty acid composition, and harvest index in both cropping years. Greater effects on N yield efficiency (NYE), N use efficiency (NUE), N physiological efficiency (NPE), and photosynthetic N use efficiency (PNUE) were recorded in nitrogen-enriched compost+PGPR inoculant (NECPI) treatment followed by chemical N fertili-zer+PGPR inoculant (CNFPI) treatment. Statistically significant differences were observed in linoleic and linolenic acid, NYE, and NUE for treatment year interaction, thus, suggesting that the integrated N biofertilizer approach facilitates the efficient N use by sunflower for improving yield and seed quality. Moreover, we also found considerable enhancement of soil N fertility after two consecutive cropping years of sunflower. The enhancement of seed quality, N use efficiencies, and soil N fertility through integrated N biofertilizer application emphasizes the importance of balanced crop N nutrition, ensuring sufficient N supply to sunflower with adequate N balance in soil for the next crop. Overall, combination of PGPR with NEC amendment may optimize N uptake efficiency and reduce N fertilizer losses, which is necessarily required for the sustainable sunflower production.

Impact of no‐tillage on soil quality and crop yield in Asia: A meta‐analysis

No-tillage (NT) (or zero-tillage) has been widely used to mitigate the adverse effects caused by intensive tillage. However, the long-term effectiveness of NT is highly dependent on agriculture field management, soil type, and climatic conditions. NT under different climatic condition fluctuations and soil conditions has not also been considered adequately in Asia. Furthermore, the high demand for food production in Asia requires a deeper understanding of the impact of NT on soil properties and crop production. Therefore, this meta-analysis was conducted using 64 peer-reviewed articles to evaluate the effects of NT on soil organic carbon (SOC), soil carbon storage, mean weight diameter (MWD), bulk density, water-stable aggregates, water content, other soil chemical properties, and yield responses. Our results showed that NT significantly increased SOC content overall than conventional tillage (CT). Likewise, as observed at a 0-10 cm soil depth, SOC content significantly increased by 77.0% in NT compared to CT. Alternatively, although overall, NT favoured the accumulation of soil C by 53.2% than CT, and this difference was even more impressive at the 0-10 cm layer by 77.0% than CT. Moreover, overall NT significantly increased MWD, soil available P, and >2 mm aggregates than CT. In contrast, even though NT did not significantly decrease smaller than the 0.25 mm aggregates than CT in the 0-10 cm layer, NT increased exchangeable K by 81.0% than CT. Results also showed that while NT and CT had no significant effects on crop yield, NT slightly increased soybean and wheat yield, and CT increased rice and maize yield than NT. Based on these results, NT is proposed as a promising practice to enhance soil quality and is plausible to increase crop yield in Asia.
