“…In further support of this, several studies on cereal-legume intercropping in Denmark [6,[15][16][17][18][19][20][21][22] have also reported enhanced yields and resource use efficiency in intercropping systems. Studies in other countries have also shown this trend, for example Dordas et al [23] in France reported enhanced yields with higher crude protein in pea-oat intercrops, Sobkowicz andŚniady [24] in Poland showed enhanced protein content from intercrops, and Danso et al [2] in Iceland reported that N uptake per oat plant was higher in the pea-oat intercrop than in the oat monocrop. Furthermore, the timing and amount of fertilizer application influences the utilization dynamics that contribute to improvements in use efficiency and productivity in intercrops [25][26][27][28]; it is therefore of the utmost significance to evaluate the N uptake at different fertilizer application timings for intercrop and sole crops to improve fertilizer use efficiency.…”

Cereal–legume intercropping increases the nitrogen (N) input from biological nitrogen fixation (BNF) and improves the exploitation of fertilizer and soil N, often leading to higher grain N content and higher productivity per unit land area compared to monocrops. Previous studies have found that these effects are more tangible under low soil and fertilizer N conditions compared to high N availability, and there is a need to assess the N uptake at critical crop development stages in order to time the N application for maximum uptake and use efficiency. The objective of this study was to assess the productivity of pea–barley intercropping compared to monocropping under 0 kg N ha−1 (0 N) and 100 kg N ha−1 (100 N). In 2017, a split plot experimental design was implemented with pea (Pisum sativum) sole crop (SC pea), barley (Hordeum vulgare) sole crop (SC barley), and pea–barley intercrop (IC total) as the main plots and 100 N applications in two 50 kg N ha−1 splits at 30 and 60 days after emergence as subplots within the main plots. The Land Equivalent Ratio (LER), based on grain dry matter (GDM) yields in the pea–barley intercrop (IC total), was higher (1.14 at 0 N and 1.10 at 100 N), indicating 10–14% greater radiation, nutrient, and water use efficiency compared to the sole crops and 4% greater resource use efficiency at 0 N compared to the 100 N; this illustrated greater total intercrop productivity compared to sole crops. The 100 N treatment decreased the SC pea and pea in intercrop (IC pea) GDM and grain dry matter N (GDMN) and increased the GDM and GDMN in SC barley and barley in the intercrop (IC barley). Intercropping increased the grain N content and therefore the protein content of the grains in 0 N and 100 N treatments. The highest fertilizer N yield, % nitrogen derived from fertilizer (%NDFF), and % nitrogen use efficiency (%NUE) were achieved in SC barley followed by IC total, indicating that intercropping improved the soil and fertilizer N use compared to SC pea. The IC pea increased the % nitrogen derived from atmosphere (%NDFA) from 67.9% in SC pea to 70.1% in IC pea. IC total increased the share of %NDFF, %NDFS, and %NDFA compared to the SC pea, which indicated a significant advantage of intercropping due to the complementarity of the component species under limited N supply in the field.

“…Environmental conditions may strengthen or weaken competitive abilities of species leading to strong dominance of one component over the other in the intercrop. If cereal severely dominates legume in 50%/50% substitutive intercrop it may not be able to compensate for legume yield loss to maintain high yield of the intercrop Parylak 2002, Sobkowicz andŚniady 2004). This may suggest that under conditions unfavorable for one component species, the second species should be represented by greater number of plants in the intercrop system.…”

47The rationale behind intercropping, as a method of sustainable crop production is that the more diverse system represented by two or more crops grown together should better utilize common limiting resources than the species grown separately. The first problem that can be met when planning efficient cereal-legume intercrop is the choice of the appropriate ratio of component species that produces maximum yield of the intercrop. However the highest yielding ratio of species cannot be known beforehand, in many experiments researchers form the intercrop by adding half of the recommended in pure stand seeding density of each of the component species. The design is termed then "proportional replacement series design" or "proportional substitutive design" (Jolliffe 2000) with 50%/50% proportion of the components. In the design, proportion means the percentage of seeding density derived from pure stand and used to form the intercrop. Using the only one ratio of species in the intercrop is usually the result of limitation in size of any intercrop experiment because an additional factor is often used in such research, for instance different rates of fertilizer. Levels of the factor are then multiplied by pure stand and the intercrop treatments enlarging experimental structure. Such an approach is appropriate, but according to Connolly (1986) the most productive ratio of components in the intercrop can be found only experimentally.The second problem in the intercropping practice is the proper choice of total density of plants per unit area for an intercrop, namely the lowest total density of plants that produces maximum yield of the intercrop. Plant density of a most productive intercrop may be higher than that imposed by the rule used in proportional substitutive design because it may be assumed that component species are able to better utilize resources when intercropped then when they are grown alone (Spitters 1983). Even if the issues are being considered prior to sowing, the next difficulty in designing the efficient intercrop results from unpredictable outcome of interactions between component species and between the species and the environment (Fukai and Trenbath 1993 ABSTRACTIn a microplot experiment conducted in 1999 and 2000 on light soil triticale and field beans were grown as sole crops and in the intercrop system. Two pure stand plant densities were established: 200 and 400 plants/m 2 for triticale and 50 and 100 plants/m 2 for field beans. Four possible intercropping combinations were obtained by adding densities of both crops. Triticale was a better competitor than field beans in all intercrops resulting in competitive balance index significantly greater than zero. The number of pods per plant of field beans was significantly reduced in all intercropping combinations compared to the pure stands, however quality of grain of the legume was unaffected by competition. Intercrop comprising 200 plants/m 2 of triticale and 50 plants/m 2 of field beans was most productive in the experiment but addition 50 more pla...

“…Whitmore and Schröder (2007) concluded in their study that the yield and profitability of intercropping systems can be contrary correlated to the residual nitrate at harvest and intercropping systems can be used to reduce nutrient pollution from agricultural practices as keeping yields. Sobkowicz and Sniady (2004) reported that triticale-bean intercropping system resulted in more benefit for nitrogen uptake than for total yield.…”

Different systems have been investigated that can increase the yield to be taken from agriculture area in order to increase the crop production decreasing with the decrease of the agricultural areas available in the worldwide. One of these systems is intercropping. Intercropping is characterized as production of two or more different crop species at same time on the same piece of land. Intercropping is one of the most effective methods in agricultural production with a long history. It is known as the achievement of a high and stable production that not only raises complementary products in the area but also reduces the harmful effects of diseases and pests, prevents pollution and results in effective use of resources. In this review study, it is informed about the use and importance of the intercropping system which is mainly based on very old ones and which is of great importance in recent years in agricultural production.
