A field experiment was conducted during 199597 and 1996-98 to study the effect of different genotypes (CoS 90269, CoPant 90223 and CoS 86218) of sugarcane (Saccharum officinarum L.) with various planting seasons (autumn, spring and summer) and nitrogen levels (1 12.5, 150 and 187.5 kg Nlha) on cane quality, productivity and economics of sugarcane production system. Genotype CoPant 90223 gave the highest commercial cane sugar equivalent yield (12.2 .. and 12.8 tonnestha in December and February respectively), cane equivalent yield (100.68 tonnestha), net returns (Rs 48,068tha) and benefit : cost (1.8). Intercropping of Indian mustard [Brassica juncea (L.) Czernj. & Cosson] with autumn sugarcane was found advantageous over sole cane planting and resulted maximum cane-equivalent yield (94.0 tonnestha), CCS equivalent (1 1.9 tonnesl ha) and net return (Rs 38,262lha). Increasing nitrogen levels during both the seasons increased cane yield and net return.References
