Water management to maximise farm income from irrigated dry crops -A field study in Tamil Nadu

Abstract

The field study is to evolve a suitable method/approach to 'maximise farm income' from irrigated dry crops that could be raised in an area under a Major Irrigation System in Tamil Nadu.
 Availability of water for irrigation is a constraint here. Effective utilisation of this scarce resources. Num Methods is therefore essential. Optimal utilisation of this limited quantity of water will enable to spread the benefits to a larger group of people of the region.
 Developing an 'optimal crop pattern' to achieve effective utilisation of the scarce resources is a pre-requisite to tap the full potential of the farm's for maximising the benefits. Evolving this optimal crop pattern' is possible" only with the adoption of a suitable optimization technique. Any optimization technique requires detailed and reliable information on resource requirements of different crop types. These basic information is not generally available for this study and is also difficult to acquire. With this limitation an attempt had been made here to evolve an 'optimal crop pattern'.
