Abstract: Water is prime for all biological activities and now days, water has been recognized more precious than gold and oil. Hence, field experiment was conducted to study the influence of irrigation methods, irrigation regimes and mulches on the performance of rabi sweet corn during rabi season of years 2014-15 and 2015-16 on coastal lateritic soils of konkan region. The experiment was laid out in split plot design with four main plot and five sub plot treatments. The main plot treatments comprised of four combinations of irrigation methods and irrigation levels viz., Drip irrigation with 100 % water requirement, Drip irrigation with 75 % water requirement, Check basin irrigation with 100 % water requirement and Check basin irrigation with 75 % water requirement. The five sub plot treatments consisted different types of mulches viz., No mulch i.e. control, Paddy straw mulch, Black polythene mulch, Transparent polythene mulch and Silver polythene mulch. Thus, there were twenty treatment combinations, replicated thrice. Results in the pooled mean data revealed that the maximum cob yield and net return can be achieved by the intervention of drip irrigation and black polythene mulch (ID100M2). The results showed that the maximum water use efficiency can be achieved with the application of one ha.cm water under treatment ID75M2 as well as 126.19 can be fetched with the investment of one m3 of water in this treatment. Drip irrigation with 75 % water application without mulch (ID75M0) recorded higher water use efficiency and water productivity as compared to 100 % water application through drip without mulch (ID100M0). Application of 75 % irrigation water through drip along with the use of polythene mulches produced higher water productivity as compared to application of 100 % water through drip along with polythene mulches.
