A field experiment was conducted at SBI, RC, Karnal, to assess performance of newly developed six mid early maturing sugarcane cultivars i.e. Co 0116, Co 0118, Co 0237, Co 0238, Co 0239 and Co J 64 (Standard), with two row spacing (75 and 90 cm) under three fertility levels i.e.75, 100 and 125% of recommended dose of fertilizers (RDF) NPK (N150 P21.8 K41.5) with plant-ratoon-wheat system. Varieties ‘Co 0238’ and ‘Co 0118’ recorded the maximum and significantly higher cane yield (93.1 and 88.9 t/ha) and commercial cane sugar (11.76 and 12.49 t/ha) and outperformed rest cultivars in plant and ratoon crop, respectively | Performance of early maturing sugarcane Saccharum spp Hybrid Complex varieties under different row spacing and fertilizer levels in plant cane-ratoon-wheat system
