“…Compared with the three mulching modes, non-mulching treatment generally produced a slightly high crop water use, but the difference was not significant among the four modes. These results are in good agreement with the findings by Lin et al (2016), who observed no significant differences in crop water use among different mulching modes. At the early growth stage, dryland maize plants were smaller and the consumption of water was mainly via soil evaporation.…”

High and efficient use of limited rainwater resources is of crucial importance for the crop production in arid and semi-arid areas. To investigate the effects of different soil and crop management practices (i.e., mulching mode treatments: flat cultivation with non-mulching, flat cultivation with straw mulching, plastic-covered ridge with bare furrow and plastic-covered ridge with straw-covered furrow; and planting density treatments: low planting density of 45,000 plants/hm 2 , medium planting density of 67,500 plants/hm 2 and high planting density of 90,000 plants/hm 2) on rainfall partitioning by dryland maize canopy, especially the resulted net rainfall input beneath the maize canopy, we measured the gross rainfall, throughfall and stemflow at different growth stages of dryland maize in 2015 and 2016 on the Loess Plateau of China. The canopy interception loss was estimated by the water balance method. Soil water storage, leaf area index, grain yield (as well as it components) and water use efficiency of dryland maize were measured or calculated. Results showed that the cumulative throughfall, cumulative stemflow and cumulative canopy interception loss during the whole growing season accounted for 42.3%-77.5%, 15.1%-36.3% and 7.4%-21.4% of the total gross rainfall under different treatments, respectively. Soil mulching could promote the growth and development of dryland maize and enhance the capability of stemflow production and canopy interception loss, thereby increasing the relative stemflow and relative canopy interception loss and reducing the relative throughfall. The relative stemflow and relative canopy interception loss generally increased with increasing planting density, while the relative throughfall decreased with increasing planting density. During the two experimental years, mulching mode had no significant influence on net rainfall due to the compensation between throughfall and stemflow, whereas planting density significantly affected net rainfall. The highest grain yield and water use efficiency of dryland maize were obtained under the combination of medium planting density of 67,500 plants/hm 2 and mulching mode of plastic-covered ridge with straw-covered furrow. Soil mulching can reduce soil evaporation and retain more soil water for dryland maize without reducing the net rainfall input beneath the maize canopy, which may alleviate the contradiction between high soil water consumption and insufficient rainfall input of the soil. In conclusion, the application of medium planting density (67,500 plants/hm 2) under plastic-covered ridge with bare furrow is recommended for increasing dryland maize production on the Loess Plateau of China.

“…A similar effect was noted by Bogunović et al (2018b) RT has a similar negative effect on crop yield as no-tillage (Pittelkow et al, 2014) which can be noted at bare plots in this study, but reduced tillage systems MT and RT with straw mulch resulted in higher yield (25%; 20%) in comparison to plots without straw (Figure 8). This effect has been noticed by Dossou-Yovo et al (2016) and Lin et al (2016). Also, straw cover provided 15% higher yield (Figure 8).…”

Soil tillage management can have positive and negative short-term effect on agroecosystem. Therefore, searching for optimal tillage management is crucial for the maintenance and improvement of soil functions. The purpose of this study was to analyze the impact of conventional tillage (CT), minimum tillage (MT) and reduced tillage (RT) on Fluvisols in humid environments (Croatia). Under each treatment, subplots with and without straw were applied. The impact was assessed on physical soil properties and soybean (Glycine max (L.) Merr.) yield. Soil bulk density was significantly lower in RT with straw when compared to the other treatments. Straw significantly effected bulk density at 10-20 cm depth.Penetration resistance did not exceed the value of 2.5 MPa on any treatment, it was also significantly reduced on covered plots in Autumn. Soil water content showed higher values in straw treatments at MT and RT. Water stable aggregates percentage were high at straw plots and at MT and RT in addition to CT. Moreover, soybean grain yield was higher in straw plots at RT and MT. It can be recognized in the aspect of short-term results that the MT and RT is an advisable alternative for CT due to its positive impact on soil physical condition and grain yield.

“… 27 and Lin et al . 37 , who attributed their results to surface cover and improvements in rainwater harvesting and soil moisture conservation, and the shading effect of the canopy under a mulch was greater than under CK. Our results demonstrated that among the various mulch treatments, RFPS gave the maximum yield and WUE, followed in the order by FPP and FPS, with all differences being significant ( P < 0.05) (Tables 1 and 2 ).…”

Mulching is critical for increasing water availability and hence winter wheat production in dryland farming systems. A two-year study was conducted to assess the effects of mulches on soil water storage (SWS), temperature, water use efficiency (WUE) and yields of winter wheat on the Loess Plateau. Four treatments were examined: conventional flat planting (CK), straw mulch (FPS), transparent plastic film mulch (FPP) and ridge-furrow with plastic film-mulched ridge and straw-mulched furrow (RFPS). Compared with CK, RFPS greatly increased SWS from 0–60 cm, FPP increased SWS from 0–40 cm, and FPS slightly increased SWS from 0–60 cm; however, FPP significantly (P < 0.05) decreased SWS from 61–100 cm. RFPS and FPP increased soil temperatures in cold seasons relative to CK, especially in RFPS (2.0–2.3 °C). Meanwhile, the rate of soil temperature increase was greater in RFPS and FPP than in CK but was lower in FPS. Mean yields were significantly increased in RFPS (56.78%), FPP (44.72%) and FPS (9.57%), and WUE was significantly increased in RFPS (44.04%) and in FPP (37.50%) compared with CK (P < 0.05). We conclude that ridge-furrow planting with plastic film-mulched ridge and straw-mulched furrow has a good potential for raising winter wheat production on the Loess Plateau.
