“…This can result in weed suppression and a reduction in weed diversity. Similar results have been reported in previous studies, which have shown intercropping can effectively suppress weed growth due to the shading effect of the crop canopy [31,33,61].…”

“…The crop observations, economics, and yield data were indicated in the other extracted reports from this excrement which indicated that, the effect of the irrigation regime was not significant on flower number, fresh weight of flower, and dried stigma yield of saffron. In intercropping ratios, the highest flower number (141.5 ± 4.26 m −2 ), fresh weight of flower (108.22 ± 3.4 g m −2 ), and dried stigma yield (4.1 ± 0.01 kg h−1) were observed in saffron mono-crop and approximately equaled by C3 treatment [61].…”

Saffron (Crocus sativus L.) is among the world’s most expensive crops; nevertheless, it struggles to compete with weeds. Non-chemical farming practices, such as intercropping and reduced irrigation, can help to decrease weed problems. Therefore, this study aimed to evaluate the changes in the weed density, biomass and weed diversity under saffron-chickpea intercropping system with two irrigation regimes. The study’s treatments included two irrigation regimes, namely one-time irrigation and conventional irrigation (carried out four times from October through May), and six planting ratios of saffron and chickpea, namely saffron sole-crop (C1), chickpea sole-crop (C2) in eight rows, 1:1 (C3), 2:2 (C4), 2:1 (C5), and 3:1 (C6)] as main and sub-plots, respectively. The result showed that the conventional irrigation regimes increased weed diversity, however, it didn’t affect the Pielou index. Intercropping ratios decreased weed diversity compared to saffron and chickpea mono-cropping systems. The interaction effect of treatments was significant for weed density and weed biomass. In most intercropping ratios, weed density and weed biomass decreased under one-time irrigation regimes. The lowest values for weed density and biomass were observed with an average of 15.5 plants/m2 and 37.51 g/m2, respectively, under the one-time irrigation regime with C4 intercropping systems. This intercropping system did not show a significant difference with C3. Overall, the results indicate that a one-time irrigation regime and intercropping with chickpea, specifically with a 1:1 saffron-chickpea ratio (C3) and a 2:2 saffron-chickpea ratio (C4), could be effective strategies for weed management in saffron in semiarid cropping systems.

Aims Studying the effects of maize and soybean intercropping for improving maize yield, and maintaining stability of maize yield under different phosphate (P) application rates in red soil is important for promoting the maize productivity, improving soil fertility and optimizing P nutrient management in southwest China. The objective of this study was to evaluate the dynamic changes of maize yield, yield stability and soil fertility under monoculture and intercropping maize with different P application rates. Methods A six-year field experiment was conducted from 2017 to 2022 to investigate the effects of maize intercropping with soybean on the yield stability and sustainability of maize according to the changes in maize yield, biomass, Partial land equivalent ratio of yield (pLERY), actual yield loss index (AYL), contribution rate of soil capacity and fertilizer (SCR, SFCR) over time, as well as the differences in coefficient of variation (CV) and sustainable yield index (SYI) at four P application rates (0 kg P ha-1, P0; 60 kg P ha-1, P1; 90 kg P ha-1, P2; and 120 kg P ha-1, P3) based on the two-factor split block design. The linear-platform model was used to simulate the relationship between the grain yield, SYI and the amount of P fertilizer under different P application rates. Results The maize yield in intercropping was significantly superior to the corresponding maize monoculture throughout the six-year experiments. For all planting years, the yield and biomass of the intercropping was higher than that of the matched monoculture average by 56.0% and 56.1%, respectively. And intercropping had an advantage of pLERY and AYL for maize. Otherwise, intercropping reduced the CV by 30.8% and 39.1%, and increased the SYI by 39.4% and 23.0% in P0 and P3 compared with matched monoculture, respectively. For all planting years, the average SFCR in intercropping treatment was higher than that in monoculture treatment. Linear-plateau model fitted showed that intercropping increased yield and SYI by 19.8% and 40.7% on platform, and reduced P application rate by 37.8% and 11.9% at inflection point, respectively. Conclusions These results demonstrate that maize and soybean intercropping could achieve higher yield, higher yield stability and SYI with lower P input than monoculture. Maize and soybean intercropping could be a sustainable practice for promoting the maize productivity and the yield sustainability in red soil of southwest China.

“…Chickpea (Cicer arietinum L.), an annual plant from the Fabaceae family, is extensively cultivated for human consumption. Its seeds are highly valued for their nutritional composition, being a rich source of proteins, vitamins, and minerals essential for human nutrition (Mohammadkhani et al, 2023). Chickpea engages in symbiotic nitrogen fixation, improving soil fertility, making it integral to crop rotations (Kaur et al, 2022), and fostering agricultural sustainability.…”

“…Chickpea engages in symbiotic nitrogen fixation, improving soil fertility, making it integral to crop rotations (Kaur et al, 2022), and fostering agricultural sustainability. Chickpea cultivation, either as a sole crop or in intercropping systems with other plant species, enhances nitrogen storage and uptake by plants, thus contributing to nitrogen fertilization management (Mohammadkhani et al, 2023).…”

This study investigated the impact of stress modifiers in intercropping systems on seed yield and yield components, physiological traits, and antioxidant activity of safflower (Carthamus tinctorius L.) and chickpea (Cicer arietinum L.) under rainfed (water deficit) conditions. The experimental design included three stress modulator levels [control, 1 mM salicylic acid (SA), and 10 mM selenium (Se)] and five planting patterns [intercropping one row of safflower and two rows of chickpeas (1S:2C), two rows of safflower and four rows of chickpeas (2S:4C), and three rows of safflower and five rows of chickpeas (3S:5C), and sole cropping of safflower (Ss) and chickpea (Cs)]. The results revealed that Ss treated with Se produced the highest safflower biological yield (4,905.50 kg ha−1) and seed yield (1,259.50 kg ha−1), while Cs produced the highest chickpea biological yield (2,799.67 kg ha−1) and seed yield (852.44 kg ha−1), followed by Cs treated with SA (2,419.25 kg ha−1 and 764.83 kg ha−1, respectively). Conversely, the 3S:5C intercropping ratio (IR) with Se application recorded the highest safflower oil content (32.08%), while Ss treated with Se produced the highest oil yield (358.62 kg ha−1). The 2S:4C configuration with Se application produced the highest unsaturated fatty acid (oleic and linoleic acids) concentrations in safflower, while 2S:4C and 3S:5C treated with Se produced the highest chlorophyll a and chlorophyll b contents in safflower and chickpea. Furthermore, 1S:2C and 2S:4C treated with SA or Se produced the highest proline and total soluble sugars in safflower and chickpea. The SA and Se treatments in the intercropping systems increased catalase, ascorbate peroxidase, and superoxide dismutase activities compared to the respective control plants (sole cropping) and enhanced oil contents, fatty acid composition, physiological traits, and antioxidant properties. These results underscore the potential of intercropping systems coupled with stress modulator treatments as a sustainable approach for safflower and chickpea cultivation under rainfed conditions.
