Influence of irrigation and nutrients on growth, yield and oil content of spring sunflower (Helianthus annuus)

, : Influence of irrigation and nutrients on growth, yield and oil content of spring sunflower (Helianthus annuus). Indian Journal of Agronomy 47(2): 255-261

An experiment was conducted at the farm of the IARI, New Delhi, India during 1998 and 1999 on spring-season sunflower (Helianthus annuus MSFH 8). The irrigation levels were 2, 3 and 4 irrigations; and the nutrient levels were N at 80 kg/ha, N at 80 kg/ha + P at 40 kg/ha, N at 80 kg/ha + P at 40 kg/ha + K at 40 kg/ha, and N at 80 kg/ha + P at 40 kg/ha + K at 40 kg/ha + S at 30 kg/ha.
