“…Various species provide complimentary use of environmental resources in a mixture in contrast to pure stands. The recent findings confirmed the benefits of intercropping, such as increased nitrogen uptake by cereals cultivated in a mixture with legumes [1][2][3], and more efficient use of water and nutrients in soil profile [4]. Different species in the mixtures also use field space more effectively [5], i.e., in weather conditions unfavorable for the growth of one species, the companion crop usually grows better [6,7].…”

“…The water content in the soil is a factor that intensifies the inter-species competition, as was shown for barley, undersown with rye-grass, which further weakens the phosphorus uptake by both barley and rye-grass [4]. Water deficit in the soil resulted in barley being a stronger competitor, with rye-grass for phosphorus.…”

“…The grain quality of spring cereal mixtures was also raised in [8], who found higher protein yields in mixtures of barley (hulled or naked grains) with wheat and the highest yields of net metabolic energy in a mixture of naked barley with wheat. Productive and ecological aspects of mixed cropping systems should be considered when recommending these cultures in climate-smart agriculture [4].…”

“…Treder et al [62] showed that barley had a stronger negative effect on wheat than vice versa, as shown in smaller increases in the dry weight of plants from tillering to heading. The competitive advantage of barley results from, inter alia, its uptake of nutrients such as nitrogen [63] or phosphorus [64], which is better and more efficient than that of co-occurring plants. Tosti et al [65] confirmed the aggressiveness and dominance of barley including in mixture with legumes, especially under conditions of high nitrogen content in the soil.…”

Peas and Barley Grown in the Strip-Till One Pass Technology as Row Intercropping Components in Sustainable Crop Production

Simplified, ploughless tillage and multi-species, multifunctional crop production are important components of sustainable agriculture. Technologies that combine these components can play an even greater pro-ecological role in modern agriculture. The claim is made that row intercropping of spring barley and peas, along with strip tillage, is an alternative to traditional methods of sowing cereals and legumes. This hypothesis was verified in a three-year field experiment in which row intercropping of barley and peas (alternating every row) was compared with traditional mixed-crop, within-row cropping (plants of each species in each row) and pure sowing of each species. Row intercropping of barley and peas using strip-till, one-pass technology, as compared with mixed-crop, within-row, improved the uniformity of plant emergence and plant density of peas before harvesting and reduced weed infestation. The productivity of barley and peas was higher than with pure sowing by 8.5% and 10.2%, respectively, and the productivity of peas was also higher by 38.9% than when sowing in mixed-crop, within-row. The yield of barley grain/seeds and peas under row-intercropping was 1.75 t ha−1 higher than the yield of pea seeds with pure sowing, and 0.79 t ha−1 lower than the yield of barley in pure sowing. On the other hand, the yield of grain/seed protein under this mixture was similar to the pea protein yield with pure sowing and 109 kg ha−1 higher than the barley protein yield with pure sowing. The positive results should inspire further research to obtain a better understanding of the conditions and effects of growing grains with legumes with strip-till one-pass technology.

“…Existing research suggests that, even if water deficit intensifies competition between plants, this is manifested in the nutrient uptake/accumulation in biomass (mostly linked to biomass volume). Its content tends to be unaffected by the interaction of these stress factors [71].…”

Undersowing catch crops (CCs) in cereals provides many environmental benefits and potentially contributes to building agricultural resilience to climate change. The increasing soil water deficit due to global warming is becoming a challenge for the sustainability of Central European agriculture. Some of the multiple functions of CCs may be altered under water shortage. Two pot experiments were conducted in Poland to assess the effect of water deficit on N, P, K, and Mg accumulated in post-harvest residues left by spring barley undersown with Italian ryegrass or red clover, and in the soil under these crops. In both experiments, barley grown alone provided a reference, and two levels of water supply were adopted: higher (sufficient for barley) and lower (reduced by 50%). Under water deficit, CCs undersown in spring barley maintained their function of capturing and storing nutrients. Post-harvest residues of barley undersown with CC and stressed with water shortage accumulated the same or higher amounts of N, P, K, and Mg than residues of barley grown alone under sufficient water supply. Soil nutrient contents were negatively correlated with crop biomass. Further research with other CC species and studies based on field experiments under rainout shelters are recommended.
