The study was conducted to evaluate long-term effect of legume intensified maize based crop rotations and contrasting tillage practices and a experiment was laid out in split plot design with three tillage practices i.e. zero tillage (ZT), permanent bed (PB) and conventional tillage (CT) as main plot treatments and four legume intensified crop rotations (MWMbmaize-wheat-mungbean, MCS -maize-chickpea-Sesbania, MMuMb -maize-mustard-mungbean and MMS -maize-maizeSesbania) as sub-plot treatments. Adoption of CA based tillage practices (ZT/PB) significantly improved maize protein yield (MPY). ZT/PB gave 7.7-14.2% higher MPY(Maize protein yield and 7.4-13.0% higher MPYA (maize protein yield for adults) over CT. Similarly, the MPY and MPYA under legume intensified cereal based rotations were invariably higher in MCS and MWMb systems compared to MMuMb and MMS rotations.The total soil nitrogen (TSN) content increased by 15.4-17.4 and 20.32-20.91% with ZT and PB over CT in 0-15 and 15-30 cm soil depths, respectively. However, among the legume intensified rotations the maize planted under MCS and MWMb rotations registered 11.3-18.0% (0-15cm) and 8.4-11.0% (15-30cm) higher TSN over MMuMb and MMS rotation. Similarly, adoption of the CA practices (ZT/PB) resulted into significant improvement in soil organic carbon (SOC) stocks compared to CT. ZT and PB among the tillage practices and MCS crop rotations among the sub-plot treatments registered higher Leaf area index (LAI) and net assimilation rate (NAR) compared to other management practices. Interaction effect of tillage practices and crop rotations were significant for MPY, MPYA, TSN and SOC stocks and all these parameters were reported maximum with ZT-MCS. Thus, our study suggests that CA based crop management with legume diversified maize based rotations (MCS and MWMb) can be advocated as sustainable intensification strategy in north-western India and other similar agro-ecologies of South Asia.

“…Potato/Onion/Garlic based systems are also more productive and profitable than cerealbased systems due to higher productivity resulting in better remuneration. This discussion holds true in the current study, when highest production efficiency in M-G-M b was reflected due to residual fertility of legumes tailored in this system (Singh et al, 2011) besides higher supply of macro and micronutrients and soil physical health (Table 5 and 6), due to better phosphatase and dehydrogenase activity by incorporating the SMB biomass (Banik and Sharma, 2009). The land use efficiency under M-P-O, M-G-M b , R-P-M b , M-P-O, and M-P-M b was recorded as 85.1, 84.8, 84.6, 83.4 and 83.3%, respectively which were at par with C p -P-M b (82.8%), O-W-M b system (81.5%) and C h -W-M b (80.2%).…”

“…As above discussed, there are variety of options for diversification of RWCS in IGPs. Diversification of wheat was discussed in detail by Singh et al (2011); Singh et al 2010; Kachroo et al (2014) and Saumi et al (2004). Diversification of rice was a main concern for Trans, upper and part of middle IGPs which includes Indian states of Punjab, Haryana and Western Uttar Pradesh.…”

“…The ameliorative effect of including legumes in continuous cereal cropping systems such as RWCS has long been known and emphasized by several others (Singh et al, 2011;Lauren et al, 2001;Johansen et al, 2000;Ali et al, 2012;Stagnari et al, 2017;Davari et al, 2012). Over time, legume crops have generally declined in importance due to low yield potential of legumes, as compared to rice and wheat and their susceptibility to many abiotic and biotic stresses.…”

The IGPs is a relatively homogenous ecological region in terms of vegetation with nearly 13 % of the total geographical area of India and it produces about 50 % of the total food grain to feed 49 % of population of India (Pal et al., 2009). In the western part of IGPs wheat is the dominating crop; while rice dominates eastern region. The IGPs are spread from 67 0 to 96 0 E longitudes and from 20 0 to 33 0 N latitude. Indian portion of IGPs extends from 21 0 31' to 32 0 20' N and 73 0 16' to 89 0 52'E and is spread over the states of Punjab,
