“…Intercropping of millet and legumes has numerous benefits regarding crop productivity and resource use efficiency, thus supporting agricultural sustainability ( 44 ). Considering a lack of data for common millet–soybean intercropping, the obtained LER values >1 for all planting patterns indicate enhanced productivity under dry land conditions and low-input systems, signifying the importance of this growing model for yield height and stability.…”

Climate changes are one of the biggest threats to food security. Sustainable agriculture, focused on eco-friendly practices for highly efficient food production, enables greater resilience and safety. This study experimented on intercropping and bio-fertilizer application as convenient ecological solutions for crop yield stability and quality. The experiment was conducted during 2018 and 2020 with soybean and common millet sown in three sowing patterns: alternating rows, alternating strips 1 (2 rows of soybean + 2 rows of millet), and alternating strips 2 (2 rows of soybean + 4 rows of millet), as well as sole crops (control), with or without a bio-fertilizer Coveron. Grain yield and nutrient grain yield response were calculated through land equivalent ratio (LER) and element-LER (E-LER), while quality was estimated based on the concentration of antioxidants (phytate phosphorus, total phenolic compounds, and yellow pigment) and elements in grains, including potential bio-availability of essential elements. Results revealed LER values to be >1 for all sowing patterns, with the highest one achieved in alternating strips 1 (1.38) together with a greater level of all antioxidants in millet grain. Intercropping significantly enhanced Fe and Mn accumulation in both crops and simultaneously decreased the concentration of potentially toxic elements (Al, Cr) in millet grain. Potential bio-availability of essential elements, expressed through the ratio between phytic acid and Ca, Mg, Fe, and Zn revealed smaller values in intercropped soybean and millet with the bio-fertilizer. The bio-fertilizer also increased the concentration of some micro-elements in millet grain, classifying it as a highly dependent plant to microbial inoculation. Interaction of intercropping and bio-fertilizer was most pronounced for LER, E-LER, and accumulation of Fe and Mn in grains. These results highlighted the benefits of soybean–common millet intercropping, especially in combination with the bio-fertilizer, in light of enhanced land utilization and nutrient absorption, thus increasing the resilience of soybean and millet under dry land conditions and low-input systems toward stability and food security.

“…In most of the parts of India, millets are grown as a sole crop during Kharif season followed by sequential Rabi crop. The area under millet was limited due to low productivity of millets compared to other cereal crops and more focus given to rice, wheat and maize but during recent period, millets have regained their importance because these of their nutritional benefits and ecological hardiness" [14], [15]. "One of the key strategies to obtain sustainable millet production is intercropping.…”

“…"Growing of two or more crops not only creates crop diversity, but also makes favourable ecology for the predators" [18]. "In other words, it may be stated better ecosystem service is created by intercropping system which leads agriculture towards sustainability" [15]. "Growing of a single crop in a year or cereals as sole crop is not so much remunerative in present scenario of agriculture to fulfil the diverse need of rapid growing population and malnutrition.…”

High population pressure, climate change, stagnant crop productivity, changing food habit and declining natural resources compelled us to go for climate resilient resource conservation technologies to bring sustainability in our crop production. Crop diversification by replacing high input requiring cereals with “nutri- cereals” minor millets in our crop rotations and by following intercropping of minor millets with pulses or oilseeds may be economically profitable, environmentally safe and socially acceptable approach to ensure food and nutritional security of the burgeoning population. This is high time to include millets in our daily diets but millet availability in sufficient amount is big issue. Millets are crops of rainfed and dryland resource poor areas and moreover under the threat of global warming and changed climatic scenario sole planting of millets generally gives less economic returns. So, there is an urgent need for incorporation of the pulses/oilseeds as intercrop in millets production system to enhance the production to feed the increasing population on sustained basis besides restoring the soil nutritional status and to overcome the environmental stress. But performance of intercropping system depends on proper selections of suitable intercrop, appropriate row ratio combination and proper input management. Very limited research work has been conducted on intercropping in millets so far but noteworthy information was recorded by the researchers, which has been reviewed through a sincere effort here to give critical view about intercropping in minor millets for agricultural sustainability to the farmers, researchers and consumers.

“…As a widely spaced crop, cotton provides ample scope for adoption of intercropping system. Intercropping is a traditional farming practice of growing of two or more crop species concurrently so that they coexist for a significant part of their growing cycle and that they interact among themselves and with agro-ecosystem Gitari et al 2020;Maitra et al 2020) [9-10, 3, 8] . In recent years, it is often recognized that intercropping system can produce higher yield than sole cropping system.…”

A front line demonstration on production potential of Cotton + Redgram intercropping system under rainfed conditions in Mahabubnagar district of Telangana state was carried out in farmers fields during 2017-18, 2018-19 and 2019-2020 under District Agricultural Advisory transfer of Technology centre (DAATTC), Mahabubnagar, PJTSAU, Telangana. Intercropping of Cotton and Redgram was sown in 4:1 ratio with an objective of Redgram as inter cropped with cotton is evolved as an alternative sustainable cropping system to sole cotton in rainfed conditions to improve the yields and income of the farmers in the Mahabubnagar district of Telangana state. The average cotton equivalent yield was 3025 kg/ha, 2382 kg/ha and 3698 kg/ha respectively during 2017-18, 2018-19 and 2019-20 and the mean cotton equivalent yield was 3035 kg/ha. The higher net returns (Rs. 89,912) in Cotton + Redgram intercropping over check sole cotton might be due to higher cotton equivalent yield, lower cost of cultivation during all the study years. The mean benefit cost ratio was 2.47: 1 and 2.06: 1 for demo and check respectively.
