Abstract
Three field experiments were conducted in fodder maize during 2013-14 and 2014-15 at MARS, UAS, Dharwad on effect of spacings, fertility levels, micronutrient application methods on growth, seed yield and quality traits and morphological characterization of thirteen genotypes and laboratory experiment was also conducted on effect of chemical and botanical seed treatments on seed storability under ambient conditions for twelve months.
In first experiment, the combined effect of 60 x 30 cm row spacing and 150:100:50 kg N, P2O5, K2O ha-1 recorded significantly maximum seed yield (31.58q/ha) as against 75 x 30 cm and 75:100:50 kg N, P2O5, K2O ha-1 + 50% N supplemented through FYM (27.89 q/ha). Whereas, seed germination (98.50%), seedling vigour index (4164) were highest in 75 x 30 cm and 150:100:50 kg N, P2O5, K2O ha-1 as against 60 x 30 cm and 75:100:50 kg N, P2O5, K2O ha-1 + 50% N supplemented through FYM (93.50% and 3559, respectively).
Soil application of Zinc sulphate @ 25 kg ha-1 + foliar spraying of 0.2% boron at 50 % flowering along with 150:100:50 kg N, P2O5, K2O ha-1 (RDF) recorded significantly highest seed yield (122.38g) per plant and (32.57 q.) hectare, seed germination (99.17%) due to better growth, flowering and yield components.
Seeds treated with vitavax power @ 3 gkg-1 of seeds retained higher 100 seed weight (29.70g), germination (90.50%), seedling vigour index (2891) and least seed infection (5.55%) as against untreated control seeds throughout twelve months ambient storage period.
Thirteen fodder maize genotypes were grouped based on DUS guidelines as presence and absence of brace root anthocynin colouration, straight and drooping leaf attitude, silk colour, dent and flint grain types, white and orange seed colour. Among different characters studied, anthocynin colouration of brace roots was distinctly absent in the MFM-07-03, MFM-07-07 and MFM-07-11 genotypes over other genotypes.
