Abstract

                                A field trial was conducted at Agricultural Research Station, Pattukkottai with ten different systems during 1984-1986 to evolve a suitable cropping system for the sandy loam soils of new delta of Thanjavur District. The results indicated that there is a possibility to introduce a four crop sequence (rice-blackgram-gingelly-greengram within a field duration of 340 days) with highest net profit (Rs. 21, 457 ha) and high cost benefit ratio (3.61). The existing rice-groundnut-maize may be improved by intercropping groundnut with blackgram or soybean. Gingelly and blackgram can be cultivated either in the second season (Dec.-Apr.) or in the third season (May-Aug.).
