“…Legume-maize mixtures can be used as a local, protein-rich forage [20], while also having a positive ecological impact by increasing the soil fertility due to the N fixation by rhizobia in symbiosis with legumes [21,22]. Various researchers have proved that intercropping provides more effective use of land area than monocropping [17,23,24]. Many other benefits result from intercropping, such as erosion control [2] and ecosystem stability due to the diversity of organisms [25,26], further emphasizing the importance of plant diversity in agriculture.…”

Abstract:Maize is grown on a large area in Germany and there is a growing concern in society about negative environmental effects related to this. The objective of the study was to test the performance of mixtures of maize and climbing beans as an alternative to monocropped maize under different site and management conditions. The effects of sowing density of maize and beans as well as the sowing time of beans on total dry matter (DM) yield and bean DM contribution to the total yield were investigated. Further, various mechanical and chemical weed control methods were tested and the resulting total DM yield was compared with that of a reference treatment (manual weeding). Hardly any consistent yield difference between maize/bean mixtures and monocropped maize occurred. The proportion of beans varied over a wide range among sites and was consistently higher when beans were sown at an early growth stage of maize. Mixtures did not suppress weeds efficiently and at two of the three sites their yield clearly declined with increasing weed coverage in the mixtures. A weed coverage of up to circa 10% may be tolerated, as the corresponding yield reduction is less than 1 t ha −1 . Considering the additional effort (i.e., two sowings, high costs for bean seeds, complicated weed control) in managing such mixtures, it can be concluded that maize/bean mixtures can currently hardly be recommended as an alternative to monocropped maize for feedstock production.

“…Faba bean ( Vicia faba L.) is one of the most commonly used grain legumes as an intercrop with maize ( Zea may L.) [ 6 , 11 , 19 ]. Faba bean and maize intercropping were found to improve yield [ 10 , 19 , 20 ], land-use productivity [ 21 , 22 ], soil fertility [ 6 , 23 , 24 ], and to reduce damage of weeds and pests [ 21 , 25 ]. These benefits can be enhanced by the selection of appropriate management related to the component crops including planting density, time of planting, choice of compatible varieties, and planting arrangements [ 1 , 11 , 19 , 26 ].…”

Continuous adoption of improved maize varieties in the last three decades has changed farm landscapes from heterogeneity to maize homogeneity in semiarid areas of Ethiopia. This has substantially decreased maize productivity. Recently, farmers have integrated faba bean into maize-based farming systems aimed at increasing productivity. Yet, there is limited information on the effects of maize-faba bean intercropping on productivity and land-use efficiency. We studied the effects of maize intercrops with two faba bean varieties (Gora and Moti) at three different densities (25, 50, and 75%) of the recommended sole faba bean (250,000 plants ha−1) on yield, economic return, and some soil fertility indicators in Tigray, northern Ethiopia. Randomized complete block design with three replications was used for the experiment. The intercrops revealed that a significantly higher total grain yield, economic revenue, and land equivalent ratio (LER) over the sole cropping. Intercrops also showed higher soil organic carbon and total nitrogen compared to the preplanting soil and sole maize. Maize intercropped with the Gora faba bean variety at a density of 50% increased the total grain yields, economic return, and LER, respectively, by 13, 42, and 38% over the sole maize. The intercrop also increased soil total N by 55 and 22% compared to the preplanting soil and sole maize, respectively. Intercropping maize with faba bean significantly improved crop yield, income, land-use productivity, and some soil fertility indicators than either the sole maize or faba bean crop in the semiarid region of northern Ethiopia.
