Abstract

Field experiment was conducted at Central farm, Agricultural College and Research Institute, Madurai, during rabi 2009 - 2010 to study the Influence of drip fertigation on the growth and yield of rice varieties (Oryza sativa L.). Drip irrigation was scheduled once in three days and fertigation was given once in six days as per the treatment schedule. Observations on growth, yield attributes and yield of rice were recorded. Drip irrigation at 150 per cent PE+ drip fertigation of 100 per cent (RDF)+ azophosmet + humic acid recorded 19 per cent increased yield as compared to drip irrigation at 125 per cent PE+100 per cent RDF through drip. The increase in rice grain yield with drip irrigation at 150 per cent PE+ drip fertigation of 100 per cent RDF + azophosmet + humic acid was mainly attributed by greater and consistent availability of soil moisture and nutrients which resulted in better crop growth, yield components and ultimately reflected on the grain yield.
