COMPARATIVE ECONOMIC ANALYSIS OF CROP PLANS IN A SODIC SOIL UNDER INTEGRATED MANAGEMENT OF RECLAMATION

ABSTRACT

The present study was undertaken with the objective to condut a comparative economic analysis of three crop plans involving two harvests of cucurbitaceous and a rice crop in each plan, in an alluvial salt affected soil submitted to integrated management of reclamation, utilising the net returns as a determinant parameter for best alternative. The three crop plans utilized were: 1. Rice (1^st Semester) + 2 crops of melon musk (2^st Semester); 2. Rice (1^st Semester) + 2 crops of watermelon (2^st Semester); 3. Rice (1^st Semester) + 2 crops of Squash (2^st Semester). The analysis of results demonstrated that 1^st crop plan consisting of one crop of rice (1^st Semester) and 2 crops of melon musk presented the best economic alternative.
