Abstract: This study evaluated the effects of a nonwoven polypropylene (NPP) covering during overwintering with different mulch types and transplant times on bulb onion growth and yield of intermediate-day onions (Allium cepa L.) during the 2015/2016 and 2016/2017 growing seasons. Field experiments were conducted using a split-split plot design with three replicates.

The object of research is onion, cultivated as an annual crop in the Nonchernozem zone of the Russian Federation. The aim of the research is to develop an improved technology for the production of bulb in an annual crop, providing a yield of 70-80 t/ha on alluvial meadow soils of the Nonchernozem zone. Research method - field test. It has been established that the probability of performing each technological operation should be at least 95%. Sowing the seeds, which are previously cleansed from the rot, must be done at an earlier date. The required yield was achieved at N 200 P 160 K 280 + Humic chemical "Rostok" + 10 l/ha BisolbiSan, Azotovit, Phosphatovit biopreparations in equal proportions. The use of the microbiological preparation BisolbiSan in 1% concentration with chemical two-component fungicides (excluding copper-containing ones) increases the immunity of onion plants. In conditions of warm, humid summer, fungicidal treatments of onions are optimal at intervals of 7-10 days from the third decade of June to the end of July. The maximum weed suppression is provided by the post-sowing application of the Stomp Professional + Dual Gold tank mix (3 + 1 l/ha) in combination with the subsequent pre-emergence treatment with Reglon Forte (2 l/ha) and the post-emergence Goal 2E (0.5 l/ha).

Mulches are materials applied in a soil surface for different roles and purposes. Plastic mulches with different colour have been developed and utilized in different crop production systems. Using coloured plastic mulches is mainly focused in modifying the radiation budget and decreasing the soil water loss. Besides, it helps to regulate soil temperature, water use efficiency, plant growth, yield, quality and weed and insect infestation. In this review, the knowledge and possible application of coloured plastic mulches, which can improve the soil physical properties, growth, yield, and quality crops has been reviewed and discussed. The role of coloured plastic mulches to mitigate the harmful effect of environmental stress in crops is also examined. Various physicochemical processes leading to improved crop production under the effect of coloured plastic mulches are also discussed. The combined results indicated that, effect of coloured plastic mulches is highly significant on soil temperature, moisture and water holding capacity. While black and blue plastics increase soil temperature, clear and white decreases it. Higher number of fruits, number of roots, tubers and bulbs was recorded in use of coloured plastic mulches. Similarly, the TSS, Vitamin C and juice percentage of different plants also showed significant improvement. It is also reported that weed infestation and viral diseases is highly reduced. Coloured plastic mulches also have some negative impacts like, decrease growth and yield in some plants, increase pest infestation, microplastics contamination, soil puddling, soil structural loss and reduce activity of soil-microorganisms. Therefore, use of coloured plastic mulches require close inspection of interaction with factors like; cropping season, root zone temperature, crop type, insect pest infestation and water use efficiency factors.
