Water management for agriculture is a worry in the world. The objective of this study is to provide an overview of the current knowledge on water control's technologies for the crops in wetlands. Comparison research work carried out on different irrigation systems revealed that drip irrigation can lead to 28-35% of water saving in relation to irrigation surface technic. Surface irrigation offers higher yield in relation to drip irrigation. It's necessary to improve knowledge and local communities' technics on different water control technologies in order to provide irrigation's functions in developing countries. Research efforts on three important concepts are necessary such as : (i) local communities perceptions on crops water need and the responses of differents crops technologies on crops yield ; (ii) interactions between agricultures prospects, water controls innvations and economics benefits of theses technologies.

“…Usowicz et al (2013); Pramanik et al (2015) found that Soil Solarisation Technology (SST) had a positively impact on soil temperature because It influenced the soil thermal regime by controlling for radiation balance and soil thermal conductivity (K), as well as volumetric heat capacity (C v ) in soil. Ingman et al (2015); Merante et al (2017); Roxy et al (2014); Gan et al (2012) demonstrated that the K and C v of soil are significantly impacted by soil moisture content. Furthermore, the results of their study identified increased K and C v with soil depth.…”

As a result, SMS was more useful for reducing soil moisture losses.…”

Soil Thermo-Physical Properties (TPP) depend on heat transfer in the soil. This paper presents a study on different soil solarisation technologies influenced by soil TPP. This study evaluates three factors: The tillage depth for soil at three levels (15, 25 and 45 cm), the number of plastic film at three levels (single, double and without plastic film) and three cases of fertilizers (chemical fertilizer, organic fertilizer and without fertilizer). The parameters explored in this study include soil bulk density (Mg/cm 3 ), soil porosity (%), soil volumetric moisture content (cm 3 /cm 3 ) and soil thermal diffusivity (m 2 /sec). Data management and analysis were performed using SAS 9.1 statistical software and the spilt-plot under higher values for Φ and θ for soil (52.70% and 0.231 cm 3 /cm 3 , respectively). Furthermore, the current study shows significant differences between the types of fertilizers on ρ b . Organic Fertilizer (OF) obtained a lower value of ρ b (1.2 Mg/m 3 ), compared with chemical fertilizer and without fertilizer (1.28 and 1.31 Mg/m 3 , respectively). In contrast, contrary to expectations, this study did not find significant differences between the types of fertilizer on D and θ for soil. A positive correlation was found in the interaction between the studied factors in the parameters. Furthermore, D increased with increasing soil bulk density (pb) and tillage depth.

“…According to Bu et al (2013), polythene mulch can retain precipitation, reduce water loss and increase the water use efficiency of crop plants. Despite some works been reported on the use of polythene mulch to reduce soil erosion (Zhang et al, 2013) and water conservation (Ingman et al, 2015), the effect of the mulch on managing saline soil for potential maize production has poorly been understood. The experiment was therefore conducted to estimate the contribution of polythene mulch and irrigation water for the mitigation of salinity effect on maize cultivation in the saline area of Bangladesh.…”

A pot experiment was conducted at the net house of Patuakhali Science and Technology University during rabi season 2014-15 to estimate the contribution of polythene mulch and irrigation on reducing of salinity effect on maize (Zea mays L.). The experiment was laid out in a three factors randomized complete block design with three replications. The factors were salinity (two levels: without and 5 dS/m salinity), mulch (two levels: without and with polythene mulch) and irrigation (three levels: 125, 250 and 500 ml water/irrigation). BARI hybrid maize-7 was the test crop. Every pot received the same amount of fertilizer nutrients. Crops were harvested at tassel initiation stage. Mulch increased soil temperature by 2 to 4.5°C (with average of 3.1°C) over without mulch. In without mulch condition, salinity reduced shoot fresh and dry, and root fresh and dry weight by 28.3, 10.3, 39.4 and 30.6%, respectively. In with mulch condition, however, these reductions were 1.0, 7.2, 12.3 and 12.1 %, respectively. Polythene mulch reduced salinity induced reduction of the above parameters by 96.5, 30.1, 68.8 and 60.5 %, respectively. Under 125, 250 and 500 ml water/irrigation treatment, salinity reduced shoot fresh weight by 14.2, 19.3 and 6.7 %, respectively; shoot dry weight by 15.4, 6.6 and 5.0 %, respectively; and root fresh weight by 27.5, 20 and 11.6 %, respectively. Thus, the effect of salinity in maize was gradually decreased with the increasing amounts of irrigation water. Soil salinity reduced phosphorus and increased sulphur content in maize plants.
