Abstract

A field experiment was conducted at G.B. Pant University of Agriculture and Technology, Pantnagar to find out productive maize cultivars for spring season. A total 12 cultivars (Pant Sankar Makka 5, Pant Sankar Makka 6, DH 300, Dekalb 9108, P 1866, Ninja, Bisco Champion 61, P 1899, NMH 589, G-0786, AHC-1212 and Pant Sankul Makka 3) were tested in RBD with three replications. The results showed that Dekalb 9108 produced significantly more cob yield (10700 kg/ha) and grain yield (8264 kg/ha) than other cultivars but was at par with P 1866, P 1899, Pant Sankar Makka 5 and Pant Sankar Makka 6. Grain yield advantage in Dekalb 9108 was 33.5, 36.7, 38.2, 39.4, 39.9, 41.5 and 47.2%, respectively over DH 300, Pant Sankul Makka 3, Bisco Champion 61, AHC-1212, G-0786, NMH 589 and Ninja. The highest net return (₹ 126638/ha) and B:C ratio (2.21) were obtained in Dekalb 9108 which were statistically more than other cultivars but remained at par with P 1866, P 1899, Pant Sankar Makka 5 and Pant Sankar Makka 6. The study revealed that Dekalb 9108, Pant Sankar Makka 5, Pant Sankar Makka 6, P 1866 and P 1899 were productive for spring season in Indo-Gangetic plain.
