“…Gu et al [23] tested PE film, biodegradable film, and non-film mulching of winter oilseed rape, and found that the yield, water-use efficiency, and grain quality did not differ significantly between biodegradable and PE films. Many researchers have reported that covering the soil with transparent film mulch can improve soil temperatures, compared with not using mulch [26]. As a crop cultivation practice, mulching has been shown to significantly increase the yields of various crops and yield components: strawberry [27]; peach [28]; oilseed rape [23]; maize [29]; spring and autumn potato [30,31]; wheat [32].…”

The experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University during the period from November 2015 to May 2016, Sher-e-Bangla Nagar, Dhaka-1207, to find out the effect of organic mulches on the yield of white maize. This experiment was comprised of two factors. Factor A: Variety (2): V1 = Shuvra; V2 = KS-510 and Factor B: Indigenous mulch materials (5): T1 = Control (without mulch); T2 = Water hyacinth; T3 = Rice straw; T4 = Rice husk; T5 = Ash. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications and the differences between means were separated by both Duncan’s New Multiple Range Test (DMRT) and Least Significant Difference (LSD) test at 5% level of probability. Mulches showed significant effects on most of the parameters. In the case of variety, the highest grain yield (12.963ton per ha) was recorded from V2. Different organic mulch materials showed different values, the highest values were recorded from T3. Due to this (T3) mulch material. The water retentive capacity of the mulched soil was higher at all the stages of plant growth and ranked in the order of rice straw > water hyacinth > rice husk > ash > control. The highest grain yield (17.407ton per ha) was recorded from T3. . In case of interaction all yield attributing characters include grain yield (19.043ton per ha) was recorded from V2T3. So, KS-510 variety and rice straw mulch combinedly had outstanding superiority for morphophysiological and yield attributes in white maize over the other organic mulches.

“…The soil water content was measured at matric potentials of −10, −40, −70, −100, −300, −700, −1000, −5000, and −15,000 cm H 2 O, and then, the values of parameters r , s , ␣ and n were estimated by the RETC code (Van Genuchten et al, 1991). We used the fitted RETC parameters as a starting value to perform an inversion for the hydraulic parameters based on the observed soil water content in NM in 2015 which has been reported in Chen et al (2017). The measured and inversed soil hydrualic parameters were shown in Table 2.…”

a b s t r a c tNumerical solution of the Richards equation with Hydrus-2D model is a low cost and fast way to get information on spatio-temporal soil water dynamics. Previous researches with Hydrus-2D have developed two different approaches to represent the rainfall infiltration in irrigated field with plastic mulching: 'BP' -an approach comprised by bare strip boundary and plastic strip boundary without consideration of film side infiltration;'BP + '-an approach comprised by bare strip and plastic strip with integrating the process of film side infiltration by increasing the rainfall infiltration amount in bare strip. Nevertheless, the performance of these approaches has not yet been evaluated in rain-fed fields. Considering much more dominant role of rainfall infiltration in rain-fed agriculture, we tested an additional approach which comprised a bare strip, plastic strip and planting hole (BPH) to take into account the effect of the rainfall canopy redistribution and film side infiltration, and we compared its performance to the two existing approaches. Results suggested BP completely failed to reproduce the soil water content (SWC) in all soil layers of plastic strip and in the deep soil layers of bare strip. BP+ overestimated the SWC in 0-20 cm of the bare strip, while the performance of BPH was acceptable in different positions. After that, we compared the soil water distribution between no-mulched field (NM) and plastic mulched field (PM) with approach BPH. Our simulation showed that the highest SWC in PM occurred near the planting hole, SWC in the center zone of plastic strip was lower, while SWC in the bare strip was lowest. PM improves the soil water availability not only in the plastic strip but also in the bare strip as compared to NM.

“…Due to the complexity of the environment, this threshold can only be obtained by field experiments; however, it is difficult to accurately simulate the field conditions in the laboratory. Chen proposed that RPF pollution assessment is conducive to agricultural production and the threshold value of RPF should be set according to local conditions [21] . According to the Ministry of Agriculture of China, the threshold value of agricultural RPF is 75 kg/hm 2 .…”

Long-term and widespread use of plastic mulching has led to the accumulation of residual plastic film (RPF) in farmland soils of Xinjiang, China. However, there is no specific quantitative basis for RPF pollution or a clear understanding of the influence of residual film on crop growth. The aim of this study was to investigate the effect of RPF on the growth of cotton, an important cash crop of Xinjiang. Based on the field conditions and previous reports, various amount of residual film was applied in 0-30 cm soil layer. The growth index including emergence rate, dry matter, and yield of cotton was examined at different growth stages under different soil residual film levels. Results demonstrated a significant effect of RPF on soil moisture distribution and movement. Plastic residues had a significant effect on cotton growth at levels above 200 kg/hm 2 , and the yield decreased as the RPF amount increased. Based on these findings, 200 kg/hm 2 was suggested as a threshold level to determine the effects of RPF on cotton. This study provided a basis to rate RPF pollution in farmland soils and help understand the impact of pollution on crop productivity.
