Title Salt-tolerant forage cultivation on a saline-sodic field for biomass production and soil reclamation
Source Land Degradation & Development
Abstract Chemical reclamation of sodic and saline-sodic soils has become cost-intensive. Cultivation of plants tolerant of salinity and sodicity may mobilize the CaCO3 present in saline-sodic soils instead of using a chemical approach. Four forage plant species, sesbania (Sesbania aculeata), kallar grass (Leptochloa fusca), millet rice (Echinochloa colona) and finger millet (Eleusine coracana), were planted in a calcareous saline-sodic field (EC(e) = 9.6-11.0 dS m(-1), SAR = 59.4-72.4). Other treatments included gypsum (equivalent to 100 per cent of the gypsum requirement of the 15 cm soil layer) and a control (no gypsum or crop), The crops were grown for 5 months. The performance of the treatments in terms of soil amelioration was in the order: Sesbania aculeata = gypsum > Leptochloa fusca Echinochloa colona > Elusine coracana > control. Biomass production by the plant species was found to be directly proportional to their reclamation efficiency. Sesbania aculeata produced 32.3 Mg forage ha(-1), followed by Leptochloa fusca (24.6 Mg ha(-1)), Echinochloa colona (22.6 Mg ha(-1)) and Eleusine coracana (5.4 Mg ha(-1)). Sesbania aculeata emerged as the most suitable biotic material for cultivation on salt-affected soils to produce good-quality forage, and to reduce soil salination and sodication processes.
