The choice of an appropriate cropping system is critical to maintaining or enhancing agricultural
sustainability. Yield, profitability and water use efficiency are important factors for determining suitability
of cropping systems in hot arid region. In a two-year field experiment (2009/10–2010/11) on loam
sandy soils of Bikaner, India, the production potential, profitability and water use efficiency (WUE) of five
cropping systems (groundnut–wheat, groundnut–isabgol, groundnut–chickpea, cluster bean–wheat and
mung bean–wheat) each at six nutrient application rate (NAR) i.e. 0, 25, 50, 75, 100% recommended dose
of N and P (NP) and 100% NP + S were evaluated. The cropping systems varied significantly in terms
of productivity, profitability and WUEs. Averaged across nutrient application regimes, groundnut–wheat
rotation gave 300–1620 kg ha−1 and 957–3365 kg ha−1 higher grain and biomass yields, respectively,
than other cropping systems. The mean annual net returns were highest for the mung bean–wheat system,
which returned 32–57% higher net return than other cropping systems. Themung bean–wheat and cluster
bean–wheat systems had higher WUE in terms of yields than other cropping systems. The mung bean–
wheat system recorded 35–63% higher WUE in monetary terms compared with other systems. Nutrients
application improved yields, profit and WUEs of cropping systems. Averaged across years and cropping
systems, the application of 100% NP improved grain yields, returns and WUE by 1.7, 3.9 and 1.6 times
than no application of nutrients. The results suggest that the profitability and WUEs of crop production
in this hot arid environment can be improved, compared with groundnut–wheat cropping, by substituting
groundnut by mung bean and nutrients application.
