“…Bare soil evaporation is determined solely by micrometeorological condition (i.e., solar radiation, air temperature and humidity and wind speed) when the amount of water available for evaporation at the soil surface is unlimited [43] . Mulching effectively prevented non-beneficial evaporation of soil water in the early stage of maize growth and created favorable conditions for water consumption in the late growth stage.…”

Based on our previous work modeling crop growth (CropSPAC) and water and heat transfer in the soilplant-atmosphere continuum (SPAC), the model was improved by considering the effect of plastic film mulching applied to field-grown maize in Northwest China. In CropSPAC, a single layer canopy model and a multi-layer soil model were adopted to simulate the energy partition between the canopy and water and heat transfer in the soil, respectively. The maize growth module included photosynthesis, growth stage calculation, biomass accumulation, and participation. The CropSPAC model coupled the maize growth module and SPAC water and heat transfer module through leaf area index (LAI), plant height and soil moisture condition in the root zone. The LAI and plant height were calculated from the maize growth module and used as input for the SPAC water and heat transfer module, and the SPAC module output for soil water stress conditions used as an input for maize growth module. We used r s , the representation of evaporation resistance, instead of the commonly used evaporation resistance r s0 to reflect the change of latent heat flux of soil evaporation under film mulching as well as the induced change in energy partition. The model was tested in a maize field at Yingke irrigation area in Northwest China. Results showed reasonable agreement between the simulations and measurements of LAI, above-ground biomass and soil water content. Compared with the original model, the modified model was more reliable for maize growth simulation under film mulching and showed better accuracy for the LAI (with the coefficient of determination R 2 = 0.92, the root mean square of error RMSE = 1.23, and the Nush-Suttclife efficiency E ns = 0.87), the above-ground biomass (with R 2 = 0.96, RMSE = 7.17 t$ha-1 and E ns = 0.95) and the soil water content in 0-1 m soil layer (with R 2 = 0.78, RMSE = 49.44 mm and E ns = 0.26). Scenarios were considered to simulate the influence of future climate change and film mulching on crop growth, soil water and heat conditions, and crop yield. The simulations indicated that the change of LAI, leaf biomass and yield are negatively correlated with temperature change, but the growing degree-days, evaporation, soil water content and soil temperature are positively correlated with temperature change. With an increase in the ratio of film mulching area, the evaporation will decrease, while the impact of film mulching on crop transpiration is not significant. In general, film mulching is effective in saving water, preserving soil moisture, increasing soil surface temperature, shortening the potential growth period, and increasing the potential yield of maize.

“…Maize in full-film mulching (FF) had significantly greater root weight density, root length density and root diameter compared to halffilm mulching and flat planting with unmulched check and FF treatment significantly improved soil water content and increased maize grain yield by 81% in 2008 and 92% in 2009 (Gao et al, 2014). Basmati rice growth and grain quality (brown and white rice length and brown and white rice recovery percentage) was significantly improved by mulch application (Jabran et al 2015). Manhas and Gill (2010) found favourable effect of mulch on growth, yield and quality of rhizome in turmeric.…”

Mulching plays an important role in production of agricultural and horticultural crops in the current scenario of declining water table, soil degradation and climate change. The main objectives of mulching are to prevent loss of water by evaporation, prevention of soil erosion, weed control, to reduce fertilizer leaching, to promote soil productivity, to enhance yield and quality of field and fruit crops. So, mulching is useful to save our underground water resource, soil and environment for sustainable crop production. In this review paper, the literature clearly shows pronounced effects of mulching on soil health by improving the soil structure, soil fertility, biological activities, avoid soil degradation in addition to moisture conservation, regulating temperature, encouraging change in favourable micro-climate, check weed growth and ultimately increasing the productivity, quality, profitability and sustainability of crops and cropping systems irrespective of the system/situation.

“…For example, weed infestation is reduced in wheat crop if grown following the sorghum crop due to release of allelochemicals from sorghum [57]. For instance, in sunflower-wheat rotation, the weed infestation in wheat crop grown after sunflower was considerably reduced [58]. Inclusion of rapeseed in rotation caused about 40% reduction in weed density in the subsequent crop in rotation [59].…”

A large number of plant and weed species produce secondary metabolites known as allelochemicals, and the process is known as allelopathy. Allelochemicals can be used to control weeds in agricultural systems by using allelopathic crops for intercropping, crop rotation, or mulching. A few important examples of crop species with high allelopathic potential may include (but not limited to) wheat, rice, sorghum, rye, barley, and sunflower. The naturally produced allelochemicals in these crops could be manipulated to suppress weeds and witness an environment-friendly and sustainable agricultural production system. The objective of this article is to review the opportunities for using allelopathy to enhance overall potentiality of weeds and crops in natural weed management. Allelopathy is the beneficial or adverse effect of one plant on another due to direct or indirect release of chemicals from live or dead plants (including microorganisms). Although we cannot discard use of synthetic herbicides completely at the present situation but their use can be reduced up to a specific extent by using allelopathic potentiality as a preferred weed management strategy for crop production as well as environmental benefits.
