Phenology and Growth of different maize influenced by nitrogen
Keywords:
: Cultivar, Dry matter accumulation, Growth, NitrogenAbstract
A field experiment was carried out to investigate the growth of different maize cultivars as influenced by graded levels of Nitrogen under temperate conditions during 2016 and 2017. Experiment was laid in Factorial RBD assigning four maize cultivars Composite-3 (C-3), Composite-4 (C-4) Composite-5 (C-5) and Composite-6 (C-6) andfive nitrogen levelsN0: 0 kg N ha-1, N1: 60 kg N ha-1, N2: 90 kg N ha-1,N3: 120 kg N ha-1 and N4: 150 kg N ha-1 andwasreplicated three times. The results revealed that growth characters like plant height (cm), and dry matter accumulation were recorded highest with composite-4 (C-4) maize cultivar as compared to other maize cultivars. To complete growth phases more days were taken by composite-4 (C-4) maize cultivar which was at par with composite-3 (C-3) maize cultivar and lowest days were taken by composite-5 (C-5). Among nitrogen levels, 150 kg N ha-1 recorded highest growth characters like plant height (cm)and dry matter accumulation however, remained statistically at par with 120 kg N ha-1 (N3) nitrogen application while lowest growth characters were recorded from N0: 0 kg N ha-1. More number of days to complete different phenological stages were taken by higher nitrogen application.
