Particularly vulnerable to potential agricultural instability are Brazil, Argentina, Paraguay, and Bolivia, where expansion of pollinator-dependent soybean farms has driven deforestation and replaced rich biodiversity that supports healthy populations of pollinators with large-scale single-crop agriculture (monoculture).
The experiment was composed of three treatments: a) in the sweet pepper monoculture: 72 plants were used, distributed in 4 garden beds with 60 cm between the plants and 1 m between the lines, with 9 plants in each line and 18 plants per bed; b) for the association of sweet pepper and basil: 72 sweet peppers plants were used with same spacing as the other treatment, and the basil were planted at the borders in a spacing of 40cm, being 72 plants in total; c) for the association of sweet pepper and marigold: 72 sweet peppers plants were used with same spacing, and marigold was planted at the borders in a spacing of 40 cm, containing 72 plants in total.
Beef cattle have a role to play in fertilising the soil through their manure and even the way they walk, he said, but he warned against the intensive farming that monocultures produce.
The present study was conducted to assess the wheat aphids' diversity and their predators association with strip intercropping (brassica, alfalfa, berseem and garlic) and wheat monoculture. Results showed that the first aphid was seen in the last week of January while the predator population was first recorded during the first week of March.
Technology executives have yet to fully recognize the risks posed by the potent political monocultures forming inside their own companies.
The results showed significant downregulation of DNMT1 in untreated HCT116 that were cocultured with nonirradiated BJ or sBJ fibroblasts compared to HCT116 monocultures. Although 1 [micro]M DAC downregulated DNMT1 levels in monoculture HCT116, the downregulation was significantly greater in HCT116 cocultured with sBJ (Figure 2(a); p = 0.03, two-way ANOVA).
In addition to the IPEC-J2/MoDC cocultures, monocultures of IPEC-J2 cells or MoDC were also included as controls to assess the influence of cocultivation on the reactivity of each cell type (Figures 1(a) and 1(b)).
Funding of up to 1,000 euros is available for farmers to trial their own mixtures on at least 2,000 sq m and compare them to a nearby monoculture. | Details: diversify@organicresearchcentre.com.
However, yields of rice cultivated on alluvial clay soil in monocultures with three harvests per year are declining in the Mekong Delta, even though farmers yearly add more fertiliser (Khoa 2002; Linh et al.
Monocultures of corn and soybean and intercropping treatments with various crop combination ratio, were significantly different in terms of silage nutritive parameters (Table 2).
In addition, it is an applicable and accessible technology that results in few environmental impacts compared to those of monocultures (REZENDE et al., 2002).
