Abstract:
A field experiment was conducted at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during rabi season of 2020-21 to study the effect of sowing dates and row spacing on forage yield of sunflower (Helianthus annuus L.). The experiment consisting twelve treatment combinations comprising four sowing dates (15th October, 1st November, 15th November, 30th November) and three row spacing (15 cm, 30 cm, 45 cm spacing) were evaluated in split plot design with four replications. Results found that sowing of forage sunflower crop in the second fortnight of October produced numerically higher plant height, green forage yield, dry forage yield and nitrogen content. Among the row spacing, significantly higher plant height, green forage yield and dry forage yield was recorded under the 30 cm row spacing as compared to rest of the treatments, whereas lower number of days to 50% flowering was found at 45 cm row spacing. Numerically higher nitrogen content was recorded at 30 cm row spacing.
