Online published on 15 October, 2015. Abstract A field experiment was carried out during winter season of 2006–07 and 2007–08 at Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar to evaluate the performance of different maize hybrids and composites in Tarai region of Uttarakhand. Hybrid Vivek-15 gave highest cob yield (12 t ha−1), grain yield (6.5 t ha−1), net returns (Rs 38576 ha−1) and benefit: cost ratio (4.09). Among the composites, Kanchan, Tarun and Navin gave higher grain yields, net returns and benefit: cost ratio than other composites. The higher grain yield was attributed to greater cob length, cob girth, cob weight and fodder yield of maize cultivars. Composite Shweta recorded the lowest growth and yield attributes, grain and fodder yield and net return values. Top Keywords Composites, Hybrids, Net returns, Production potential, Winter maize. Top |
