Description The continuous growing of rice has led to a deterioration in soil quality, resulting
in a serious threat to agricultural sustainability in the high rainfall zone of south
Gujarat, India. Therefore, crop diversification with a wider choice in the
production of crop varieties is being promoted to restore the soil quality. A field
experiment was conducted in Navsari, India during 2003–2007 on a Vertisol to
evaluate the productivity, sustainability, resource-use efficiency and economics of
10 rice-based cropping systems. The results showed that system productivity for
rice–fenugreek (Trigonella foenum-graecum)–okra (Abelmoschus esculentus) was
highest (25.73 t ha71), followed by rice–onion (Allium cepa)–cowpea (Vigna
sinensis L.) (24.15 t ha71); and the lowest system productivity was observed with
the rice–wheat (Triticum aestivum)–fallow system (7.85 t ha71). The sustainable
yield index (0.97), production efficiency (102.94 kg ha71 day71) and field water
use efficiency (15.98 kg ha71 mm71) were maximum with the rice–fenugreek–
okra system. Similarly, net return (96,286 Rs ha71), net return per rupee invested
(2.83 Rs), monetary production efficiency (385.14 Rs ha71 day71) and water use
efficiency (59.80 Rs ha71 mm71) were maximum with the rice–fenugreek–okra
cropping sequence. There were significant effects of various cropping sequences
on available nitrogen, phosphorus, potassium and organic carbon content in the
soil. Overall, the rice–fenugreek–okra system was found to be the most
productive, sustainable, resource-use efficient and remunerative cropping system,
followed by the rice–onion–cowpea system.
