SUMMARYWeed community of Swiss chard was studied in plots with different fertilization regimes. Fertilization doses correspond to 50% (F50), 100% (F100) and 150% (F150) nutrient demand of Swiss chard. Sinousia consists of 29 species, out of 26 genera and 17 families, among which dominant are: Sorghum halepense, Solanum nigrum, Kickxia spuria, and Atriplex patula. The analysis of the biological spectrum indicates the dominance of therophytes with 75.8%, while hemicryptophytes contribute the spectrum with 17.2%. Considering the effect of fertilizers on the crop growth and weediness, general conclusion is that fertilizers benefit both the crop and weeds, but increased doses of fertilizers had better effect on the crop yield than on weediness. The average crop yield was highest in the regime F150, as well as total weediness F150. However, analysing the species abundance, cover per single plot and crop yield in each regime of fertilization, some deviations are noticed. Such as, in the plots No 10 (belongs to F100) and No 17 (belongs to F150) the total weed cover was 10%. In eight plots which belongs to F50 the weed cover exceeded this value.

“…In this study, crude protein accounted for only 11.21% of the dry weight of the green forage. Papastylianou et al (2014) also reported crude protein levels of 11.1 -14.7% DM in green matter from this plant. In the samples of quinoa green forage analysed in this study, the concentrations of crude ash, crude fat, crude fibre and nitrogen-free extract were higher than those reported by Gęsiński (2012).…”

“…Owing to the valuable properties of quinoa, its unusual resistance and ecological plasticity, and its high nutritional value, the Food and Agriculture Organization (FAO) declared the year 2013 the 'International Year of Quinoa' (Kakabouki et al, 2014;Papastylianou et al, 2014). Quinoa has a long growing season and even European varieties do not mature in Poland until late September (Gęsiński, 2012).…”

Chenopodium quinoa Willd. is a new plant in the conditions of Poland. At harvest, it has a low content of dry matter, which makes it difficult to ensile. For this reason, a study was undertaken on the effect of microbial and chemical additives on selected quality characteristics of quinoa silage. Traits determining the suitability of the green forage and the influence of silage additives were assessed. A microbial additive and a chemical additive were used. The microbial additive contained bacterial strains of Enterococcus faecium, Lactobacillus plantarum and Pediococcus acidilactici (concentration 1.25•10 11 CFU•g-1) and was applied in the amount of 1 g•t-1 of fresh material. The chemical additive contained formic acid, propionic acid and ammonium formate, and was added in the amount of 5 l•t-1 of fresh material. The quality of the quinoa silage depending on the additive used was evaluated. The fresh material of Chenopodium quinoa Willd. contained only 6.42% water-soluble carbohydrates (WSC) in dry matter (DM) and its fermentability coefficient was 29.2. Lactic acid was predominant in the silage, while the content of acetic acid was average. In the control silage (without additives), small amounts of butyric acid (0.04% DM) were noted, so its quality according to the Flieg-Zimmer scale was good. No butyric acid was found in the silage prepared with additives, and their quality was very good. The control silage contained more N-NH 3 than the silage prepared with additives (P≤0.01). This indicated that the preservatives (silage additives) limited the process of protein degradation in the quinoa silage.

“…Vermicompost has been advocated as good organic manure for use in integrated management practices in field crops. Vermicompost not only increases organic carbon status of the soils but also increases soil water holding capacity, flocculation of soil and availability of nutrients and thus improves soil and crop production sustainability [21] In addition, fertilization with compost showed higher values in most quality traits of biomass in quinoa crop other than synthetic fertilizers [22]. In comparing the effect of compost and vermicompost on Amaranthus viridis production; Islam et al [23] found that vermicompost application gave higher result for growth, yield indices and nutrient content than the conventional aerobic compost.…”

Towards Expanding Quinoa Cultivation in Egypt: The Effect of Compost and Vermicompost on Quinoa Pests, Natural Enemies and Yield under Field Conditions

Increasing production and reducing pests' population while preserving the environment is an essential goal nowadays. New strategies are needed to achieve this goal, to bridge food gap and achieve food security. Quinoa is a promising crop and could partially substitute wheat in baked products and assist in overcoming wheat gap in Egypt. This study aimed to identify pests and their natural enemies in quinoa plantation, the population dynamics of both and the effect of compost and vermicompost fertilization on pests' population and quinoa yield under field conditions. The study was carried out in El Giza Research Station of the Agricultural Research Centre-Egypt, from November till March, in two successive seasons, 2016/2017 and 2017/2018. The experiment was set up in a complete randomized block design. Variety Masr 1 was tested and yellow sticky traps were used to monitor insects' numbers. Three main pests were detected: Aphis craccivora, Empoasca. decipiens and Bemisia tabaci. The most common pest was aphids followed by potato leafhoppers. Compost fertilized quinoa attracted fewer pests and resulted in less yield compared to vermicompost. Parasitoids appeared earlier than predators and their numbers were the highest throughout the two seasons. Pests' and natural enemies' peaks were determined to facilitate IPM interventions. It is recommended to use vermicompost in quinoa production rather than compost, as it increased yield, provided that an IPM strategy is implemented in which natural enemies are the main players. Further investigations are needed to understand the interaction between predators and parasitoids in quinoa field in order to maximize the benefit of their existence in IPM programs.
