TREATMENTS AND ECONOMIC ASPECTS OF GROWING RICE AND WHEAT CROPS DURING RECLAMATION OF TILE DRAINED SALINE‐SODIC SOILS USING BRACKISH WATERS

ABSTRACT We carried out three field experiments on salt‐affected soils having tile drainage in place, which differed in ambient levels of electrical conductivity and sodium adsorption ratio. The 3‐year cropping sequence consisted of a rice–wheat rotation. These crops were irrigated with waters having different levels of salinity (EC 2.7–4.5 dS m −1 ), and sodicity (SAR 8.0–28.8 and residual sodium carbonate 1.3–14.9 mmol c L −1 ). The …
