- Abstract
ABSTRACT Efficient irrigation and drainage are a prerequisite for sustainable citriculture. Citriculture in vertisols often faces the twin problem of waterlogging in the rainy season and water shortage during the post-rainy period, leading to suboptimal productivity and decline of citrus orchards in central India. With this in mind, the integrated impact of irrigation methods (drip and basin) and surface drainage (parallel trenches) was studied in citrus orchards of the region. Drip irrigation (DI) produced 23% higher fruit yield than basin irrigation (BI) under drainage. Drainage was an important consideration for both DI and BI. However, drainage was much more important for BI than DI to achieve higher fruit yield. Conjunctive use of DI and drainage (DID) reduced the soil and nutrient losses through runoff and produced 90% higher yield with better quality fruit, using 30% less irrigation water (171% improvement in irrigation water use efficiency) than BI without drainage. Citrus production with DID was also found to be economically superior to other treatments, generating more net return (INR 225 000 ha−1 yr−1)1 with higher benefit-cost ratio (5.2). Overall, the study demonstrates that adoption of DID could be a viable option for commercial citriculture on clay soil in water-scarce central India. Copyright © 2014 John Wiley & Sons, Ltd.
