AB  - This experiment was conducted under two different agro-climatic conditions of Haryana viz. humid conditions ofKarnal and semi-arid conditions of Hisar during kharif 2015 to evaluate the performance of newly developed sevenextra-early maturing hybrids of maize. The analysis of variance revealed significant differences among the hybridsfor different characters. In humid conditions, hybrid Bio9637 (5243.0 kg/ha) was highes t yielder followed by hybridVivek Hybrid 43 (5047.0 kg/ha), Vivek Hybrid 21 (4631.0 kg/ha), EH2236 (4142.0 kg/ha), Bio9681 (3694.0 kg/ha),Prakash (3644.0 kg/ha) and AH1317 (2972.0 kg/ha). In semi-arid conditions, Prakash (5017.0 kg/ha) was significantlysuperior and followed by Vivek Hybrid 43 (4977.0 kg/ha), Vivek Hybrid 21 (4294.0 kg/ha), AH1317 (4091.0 kg/ha),EH2236 (3830.0 kg/ha), Bio9637 (2990.0 kg/ha), Bio9681 (2908.0 kg/ha). Likewise, on average basis, Vivek Hybrid 43 withan average yield 5012.0 kg/ha was at the top yielder and followed by Vivek Hybrid 21 (4462.5 kg/ha), Prakash (4330.5 kg/ha),Bio9637 (4116.5 kg/ha), EH2236 (3986.0 kg/ha), AH1317 (3531.5 kg/ha), Bio9681 (3301.0 kg/ha). The grain yield meanperformance was high in humid conditions (5243.0 kg/ha) as compared to in semi-arid conditions (5017.0 kg/ha) due tomore availability of soil mois ture and nutrients.
