“…Optimising natural resources with a view to high yields and low production costs has been one of the goals of global agricultural research. As such, intercropped systems employing crops of agronomic interest are seen as a viable alternative, both from the productive and ecological points of view, as well as from the economic perspective (Li et al, 2020;Pinheiro et al, 2019).…”

Intercropping affords an increase in productivity by optimising the area used, as well as maximising input use efficiency the financial return of intercroping systems was higher than that observed in the respective individual cultures. Here we show prominently that the financial return of the consortium systems was higher than that observed in the respective individual cultures. The aim of this study was to evaluate the agronomic parameters, biological and productive efficiency, and economic performance of arugula under a single and intercropped system. The study was conducted at the Teaching Garden of the Federal University of Ceará, Brazil, in a randomised block design, with four replications and seven treatments: T1 (single arugula), T2 (arugula intercropped with coriander), T3 (arugula intercropped with parsley), T4 (arugula intercropped with garlic chives), T5 (single coriander), T6 (single parsley) and T7 (single garlic chives). Phytotechnical evaluations were carried out. Biological efficiency was evaluated based on the following factors: land use efficiency index or land equivalent ratio (LER), relative contribution of the arugula crop to the LER (CRC), area time equivalent ratio (RAET) and system productivity index (IPS). For the economic analysis, the following were evaluated: operational production costs (OC; BRL ha-1), gross revenue (GR; BRL ha-1), gross profit (GP; BRL ha-1), rate of return (RR; %) and profitability index (PI;%). The system based on arugula intercropped with coriander showed the best agronomic performance and biological efficiency. Productivity and economic advantage under this intercropped system were also superior to the other treatments.

Despite numerous positive effects on the environment, increased demands, intense research, and adequate public attention, crops grown according to the principles of organic production still occupy considerably small areas. It is difficult for certified producers to decide to expand the production of certified organic vegetables. One of the reasons is the insufficiently developed growing technology of different vegetable species in accordance with the law and regulations on organic production. Intercropping, growing of subsequent crops, and application of microbiological fertilizers are considered as the most useful techniques for yield increases in sustainable growing practices. The aim of this study was to investigate the possibilities for enhancing root yield of beetroot and radish, when grown as second crops in an organic double-cropping production system. The effects of intercropping and applying microbial fertilizers on the vegetable root weights were assessed. Intercropping was with green beans, implemented by replacement series method. Two microbial fertilizers were applied, one containing selected strains of Bacillus megatherium, B. licheniformis, B. suptilis, Azotobacter chrocoocum, A. vinelandi and Derxia sp. (M1), and other with Bacillus subtilis, Azotobacter sp., Penicillium oxalicum and Fusarium sp. (M2). Intercropping and microbial fertilizers contributed to the root weight increase. The highest root weights were noted for the intercropped plants treated with M1 (beetroot, 151.8 g) and M2 (radish, 351.0 g), which was 23.5% and 15.5% higher than in the sole crop unfertilized control. The results imply combining intercropping and the appropriate microbial fertilizers as an effective strategy for increasing yields of organically grown beetroot and radish.
