Opis:
Plastic mulch provides a range of benefits including helping modulate soil temperature, reduce soil erosion, evaporation, fertilizer leaching and weed problems and increasing the quality and yields of the product. But when the crops are harvested, plastic mulch needs to be removed from the ground for disposal. Otherwise, these wastes are mixed with the soil and have a negative impact on yields by reducing the access of nutrients and moisture in the soil. The purpose of the current study is, therefore, to propose a roller for plastic mulch retriever which is applicable when the crops are harvested, and the plastic mulch needs to be removed from the ground for disposal. The winding mechanism of the plastic mulch retriever performs the main function and must have the high-quality performance of the winding operation in the removal technology. Research based on requirements of tensile strength test method and changes of strength characteristics of plastic mulch from various factors under natural conditions. The coefficient of compaction of the used plastic mulch (Krel), was the ratio of the diameter of the standard plastic mulch which was wound in the factory to the diameter of the used plastic mulch during the winding.

Opis:
The use of plastic mulch in furrow irrigation increases irrigation efficiency and improves crop yield. In this study, the effect of the placement of plastic mulch on the furrows and/or on the ridges on reducing water loss and nitrate leaching for furrow-fertigated maize was investigated. Field experiments were carried out including four different treatments which differed according to the placement of plastic mulch on a clay loam soil: plastic mulch on the ridge, plastic mulch on the furrow bed, plastic mulch on the ridge and the furrow bed and control treatment without the mulch. The HYDRUS-2D model was used to simulate water movement and nitrate transfer within the soil. The HYDRUS-2D model was well calibrated and validated using field data. Three irrigation scenarios were also compared including 125, 100 and 75% of the crop water requirement. In the case of using mulch and full irrigation (i.e. 100% crop water requirement), nitrate losses compared to the control treatment with 25% over-irrigation decreased by 52, 44, and 30%, in the the treatments of mulch on the furrow bed, mulch on the ridge and mulch on the ridge and the furrow bed, respectively. Deep percolation of irrigation water also decreased by 53, 48, and 41%, respectively. The use of plastic mulch on the furrow bed with less irrigation depth could be used to prevent water and nitrate losses in furrow irrigation.

Opis:
The study involved experimental work implemented from April 2014 until March 2017. Its purpose was to observe grape production quality parameters, such as yield, water productivity, berry size and bio-mass. Different irrigation methods, such as drip irrigation (DI), drip irrigation with plastic mulching (DIPM), drip irrigation with organic mulching (DIOM), subsurface irrigation with stone column (SISC), subsurface irrigation with mud pot (SIMP), and subsurface irrigation with plastic bottles (SIPB) have been used during the experimental work. The crop has been irrigated following the CROPWAT-8.0 model developed by the FAO. Climate parameters are obtained from the automatic weather station located near the experimental field. Based on experimental results and analyses, it has been observed that the drip irrigation with the plastic mulching method is the best for irrigation in terms of the grape yield comparing with all other methods due to its highest productivity of 35–40%. Subsurface irrigation with the plastic bottle method is found to be suitable as it gives 20% higher yield than the traditional drip irrigation method. The SIPB method shows the cost-benefit ratio of 112.3, whereas the DIPM method had the ratio of 36.6. Based on the cost-benefit analysis, it is concluded that the SIPB method is economically more viable as compared with all other methods. Hence, based on the findings, it is recommended to use drip irrigation with a plastic mulching and drip irrigation with a plastic bottle as the best options to achieve grape productivity while using minimum water.
