“…In sole cropping conditions, the higher intraspecific competition decreased the nutrient use efficiency of nutrients. Therefore, it can be concluded that the higher nutrient accessibility by BFS application along with improvement of environmental use efficiency and better spatial, temporal and chemical complementarity of both plants in intercropping patterns enhanced the LER index when compared with sole cropping conditions 33 . Moreover, atmospheric nitrogen fixation by the legume component of the system (fenugreek) and its direct/indirect transfer to the non-legume component (fennel) reduced the competition for inorganic nitrogen at the whole system level and enhanced plant productivity by improving nutrient absorption.…”

The study investigated the effect of organic/biofertilizers in intercropping patterns on seed yield and yield components and essential oil, fatty acid, and phenolic compounds of fennel (Foeniculum vulgare L.) and fenugreek (Trigonella foenum-graecum L.). Experimental treatments included the application of humic acid (HA), biofertilizers (BFS), and the unfertilized control in five planting patterns [1 row fennel + 2 rows fenugreek intercropping (1F:2FG), 2 rows fennel + 2 rows fenugreek intercropping (2F:2FG), 2 rows fennel + 4 rows fenugreek intercropping (2F:4FG), and sole cropping of each species]. Sole cropping with BFS produced the highest seed yields for fennel (2233 kg ha−1) and fenugreek (1240 kg ha–1). In contrast, the 2F:2FG intercropping ratio with BFS yielded the maximum fixed oil content for fennel (17.4%) and fenugreek (8.3%). Application of HA and BFS enhanced oil yields by 66% and 75% in fennel and 40% and 57% in fenugreek, respectively. The 2F:2FG intercropping ratio with BFS produced the maximum essential oil constituents [(E)-anethole, estragole, and fenchone] in fennel. In addition, 2F:4FG with BFS and 1F:1FG with HA produced the highest unsaturated fatty acid (oleic and linoleic acids) concentration in both species. The 2F:2FG intercropping ratio with BFS and HA produced the highest chlorogenic acid and quercetin contents, respectively, in fennel. In contrast, the 2F:4FG intercropping ratio with HA produced the highest chlorogenic acid and caffeic acid contents in fenugreek. Intercropping fennel/fenugreek with BFS or HA improved the essential oil content (fennel only), fixed oil quality and quantity, and phenolic compounds and created a more sustainable cultivation system than sole cropping systems for both species under low-input conditions.

“…For instance, intercropping is more productive and economical when both crops differ in genetic makeup, photosynthetic pathways, growth habit, growth duration, and demand for different growth resources [12,13]. Therefore, intercropping can only provide a yield advantage over sole cropping if the component crops use natural resources in complementary ways [14][15][16].…”

Cultivating multiple crops together can provide numerous benefits, including improved soil health and crop yield. The objective of our study was to determine the optimum planting techniques in intercropping systems, and to maximize their benefits by mitigating competition for resources such as land, space, light interception, and nutrition. The performance of successively planted maize (Zea mays L.) grown with cowpea (Vigna unguiculata L.) was evaluated with a field trial in Bangladesh. The treatments in our study were: (a) sole maize, (b) sole cowpea, (c) crops sown simultaneously, and (d) crops sown with different time lags (1, 2, and 3 weeks) between the maize-sowing and cowpea-sowing dates. Data on the crops’ physiological parameters were recorded. These included light interception, leaf area index (LAI), Soil Plant Analysis Development (SPAD), harvest index, and yield. Simultaneously, canopy coverage was measured using camera-based photo analysis. In addition, an economic analysis of intercropping maize with soybean or cowpea was conducted using gross margin analysis and benefit-cost ratio. In our results, the below-canopy photosynthetically active radiation (PAR) was significantly higher in intercropping treatments when maize was sown three weeks after cowpea. In contrast, the LAI value of the maize and cowpea was significantly greater when sown on the same day than in other intercropping treatments. As a result, the maize yield reduced when intercropped with cowpea. This reduction maximized when both species were sown simultaneously due to higher competition for resources, including nutrients and light. Intercropping was more beneficial in terms of land equivalent ratio than both sole cropping of maize and cowpea, especially when maize was planted three weeks later. However, this benefit was not retained when calculated as maize equivalent yield since the contribution of cowpea was small in the overall maize yield, suggesting the importance of the relative economic value of the component species. Among all treatments, the lowest maize equivalent yield (6.03 ± 0.14 t ha−1) was obtained from sole cowpea, and the largest land equivalent ratio (1.67 ± 0.05) was obtained from intercropping with maize sown three weeks after cowpea. This treatment provided a net income of USD 786.32 ± 25.08 ha−1. This study has shown that together, maize–cowpea intercropping with a temporal niche difference of three weeks may be a better option for sustainable crop production in Bangladesh, maximizing land use. However, it may not provide a significantly greater maize equivalent yield and economic return.
