“…The results were in agreement with other studies (Zhang et al, 2017). In NT plots, soil consolidation will continue augment until an equilibrium bulk density is reached, range of 1.2-1.5 g•cm -3 for our soil type (Sayed et al, 2019). Our results were consistent with those of Sauvadet et al (2018), who found that reduced tillage doubled soil organic C (SOC) compared with CT.…”

Soil deterioration, yield decline and soil microbial activity reduction caused by banana (Musa × paradisiaca L.) monoculture is threatening the sustainability of banana production in China. Therefore, it is necessary to study the benefits of rotation on soil quality. This study aimed to assess the effects of rotation and tillage on soil properties in a banana plantation for 25 yr. Treatments consisted of three rotation methods (banana-pineapple, BA; banana-cowpea, BP; banana-rice, BR) and banana monoculture (CK) combined with two tillage intensities (no-tillage, NT; conventional tillage, CT). Soil samples were taken at depth of 0-40 cm in 2019-2020. In comparison with CK, BA and BR increased soil moisture, pH, total organic C and available P, but decreased soil bulk density. Microbial biomass C and N at booting stage were 46.1% and 39.2% higher in BA and BR than those in CK. Urease, dehydrogenase and β-glucosidase obtained a mean of 34.1% increase in BP and 23.8% increase in BR compared with BA. Higher total N, NO3-N, available K and macroaggregate were showed in NT compared with CT, whereas porosity was 24.8% lower in NT than in CT. CO 2, N2O and CH4 emissions were in average around between one third and two fifth lower in no-tillage compared with conventional tillage. In general, rotations combined with no-tillage led to a positive effect on soil quality, as evidenced by increase of soil moisture, total N, microbial biomass C and urease and accompanying increase in banana yield. In order to sustain higher productivity, application of rotation and no-tillage is of considerable importance.

“…Minimum tillage and zero tillage practices improve the availability of soil phosphorus, potassium, soil organic matter under arid climatic conditions [19,20]. Similarly, many field trials have shown that soil organic matter increases under long-term zero tillage systems [21,22]. Additionally, the microbial population also showed an increasing trend under long-term zero tillage systems [23,24].…”

A detailed field experiment was carried out to study the effect of conventional and zero tillage and legume intercrops on soil health indicators and cotton productivity and also yield components of leguminous crops at the Research Farm, MNS-University of Agriculture, Multan, Pakistan. The field experiment was comprised of four legume intercrops (no intercrops (sole cotton), mung bean, mash bean, and soybean) and two tillage systems (three years zero tillage (ZT) and long-term conventional tillage (CT)). The CT showed the highest plant height (121 cm), total bolls per plant (22.9 bolls), boll weight (2.74 g) and seed yield (2031 kg ha−1) of the cotton crop, as compared to ZT. The highest leaf transpiration rate (9.28 mmol H2O m−2 s−1), net leaf photosynthetic rate (27.17 µmol m−2 s−1), stomatal conductance (0.493 mmol m−2 s−1), chlorophyll content (62.3 SPAD value), plant height (123 cm), total bolls per plant (24.4), boll weight (2.83 g), and seed yield (2090 kg ha−1) of cotton crop were recorded when it was grown as a sole crop, as compared to legume intercrops. However, soil organic matter (0.77%), phosphorus (8.08 mg kg−1), potassium (253 mg kg−1), and microbial population (7.26 × 106 Cfu) were higher in ZT than in CT. Mung bean showed a maximum number of pods (32), seed yield (173 kg ha−1), biomass (950 kg ha−1), and harvest index (19.0%), when intercropped with cotton. The highest land equivalent ratio and area time equivalent ratio were recorded in mung bean and cotton intercropping, grown under a CT system. Furthermore, the maximum benefit-cost ratio was recorded in mung bean and cotton intercropping, over sole cotton cropping under CT (1.75) and ZT (1.67) systems. The ZT and intercropping of leguminous crops with cotton might be a promising option for increasing the seed cotton yield, seed yield of leguminous crops, system profitability, and sustainability of soil health.

“…Such weathering processes include soil erosion, leaching of nutrients and change in nutrient profile of the soil, which increase the pollution of fresh water sources. Tillage is the agricultural preparation of the soil by mechanical, draught-animal or humanpowered agitation involving activities such as ploughing, digging, overturning, shoveling, hoeing and raking (Aina, 2011) while conservation tillage is an option for maintaining soil health and the surrounding environment for intensive agriculture, especially in the tropical climate (Sayed et al, 2020).…”

The aim of the study was to examine the effects of tillage methods on surface runoff and model the pattern and processes of surface water pollution associated with tillage methods using Soil Water Assessment Tool (SWAT). This model was designed to predict the impact of land management practices on water, sediment, and varying tillage types in watersheds over two planting seasons. Traditional heap (T), Plough/Harrow (PH), Plough/Harrow/Ridge (PHR) and No-tillage (NT) methods commonly used in the study area were applied to experimental plots at Unilorin Teaching and Research Farm and National Center for Agricultural Mechanization, Idofian (Nigeria). Using Randomized Complete Block Design (RCBD), each treatment had three replicates making 12 experimental plots at each location for the 2015 and 2016 planting season. Nine biophysical parameters were purposively selected, examined and modelled. The study revealed that four of nine biophysical factors (sediment yield: 10.54 t/ha; groundwater discharge: 174.45 mm; organic nitrogen: 62.62 kg/ha, and nitrogen in surface runoff: 5.15 kg/ha) were higher for traditional heaps, while three parameters (surface runoff: 374.42 mm; evapotranspiration: 752.78 mm, and soil loss: 1.05 kg/ha) were higher under plough/harrow and plough/harrow/ridge cultivation practices. The study concluded that tillage methods have impact on water quality. However, plough/harrow has comparatively more favorable effect on the contribution to surface runoff. It is therefore recommended that this type of tillage should be adopted to reduce water pollution and for sustainable environment.
