Evaluation and performance of drainage system in waterlogged area of Krishna western delta

Abstract

The waterlogging is one of the biggest problem in the agriculture field of Krishna Western Delta region. The artificial drainage system removes the excess water from agricultural lands and may increases the crop productivity. In this study, a field experiment was conducted on rice crop in experimental field (artificial drainage system installed) and farmer field (artificial drainage system not installed) during the Kharif season of 2011-12. The agronomical parameters (tiller count, number of productive tillers, panicle length, number of fill grain per panicles, plant height and grain yield) were measured at crop maturity stage. The leachate samples were also collected from the leachate collector chamber and analyzed the salt concentration. The average salt concentration of 0.5 t/l was leached from the experimental field. The agronomical parameters show better performance in the experimental field after the installation of artificial drainage system as compared to the farmer field. The results demonstrate that the installation of drainage system in salt affected area can increase the crop growth parameters and grain yield.
