“…Hoekstra et al (2009) [33] also reported lesser WFT as the total volume of freshwater that is used to produce the product was comparatively lower. Contrary to the WUE and WP, the WPFs remained significantly higher under a conventional crop geometry (666.7 L per kg of crop economic produce) due to an exhaustive water-use pattern [82]. While the broader crop geometry (60 cm × 60 cm) led to decreased WFPs and better use of irrigation water, Shekhawat et al [7], Rathore et al [35], and Sharma et al [37] have also reported higher WP for the rapeseed-mustard and suggested the conversion of conventional rain-fed rapeseedmustard areas into irrigated areas through appropriate irrigation scheduling, which can easily meet the water requirement of the crop.…”

The article presents the findings of three-year field experiments conducted during 2017–2020 on the productivity, economics, and environmental footprints of the oilseed Brassica (OSB) with species diversification and crop geometry alterations in semi-arid regions of India. The objectives of the field experimentation was to assess the system of mustard intensification (SMI) in enhancing productivity and profitability with ensuring fewer environmental footprints. The results revealed that Brassica carinata gave a maximum seed productivity (3173.8 kg ha−1) and net returns (USS 11,417.2 ha−1) under a crop geometry of 60 cm × 60 cm. Further, an increase of 38% and 54% in seed yield and net returns from B. carinata was observed over the existing traditional Brassica juncea with conventional crop geometry. The maximum energy output was also recorded from B. carinata (246,445 MJ ha−1). The broader crop geometry (60 cm × 60 cm) also resulted in maximum energy output. The environmental footprint was lesser due to increased carbon gain (CG), carbon output (CO), and carbon production efficiency (CPE) and lower greenhouse gas intensity (GHGi) in B. carinata. However, the maximum water-use efficiency (WUE) was recorded in B. juncea (19.15 kg per ha-mm), with a minimum water footprint (WFP), whereas, greater crop geometry (60 cm × 60 cm) resulted in lower WFPs and better irrigation water use. Enhanced seed yield, economics, and fewer environmental footprints were observed at broader crop geometry in B. carinata over remaining OSBs.
