A field experiment was conducted at SBI, RC, Karnal, to assess performance of newly developed six mid early maturing sugarcane cultivars . 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 , 100 and 125% of recommended dose of fertilizers (RDF) NPK (N150 ) with plant-ratoon-wheat system. Varieties ‘Co 0238’ and ‘Co 0118’ recorded the maximum and significantly higher cane yield ( and t/ha) and commercial cane sugar ( and 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
