Effect of irrigation and antitranspirants on seed and oil yields, and quality of sunflower (Helianthus annuus L.).

摘要

Field and laboratory studies were conducted in Hisar, Haryana, India, during the 1999 and 2000 cropping seasons, to determine the effect of 5 irrigation dates and 4 antitranspirants on seed yield and its attributes, oil and protein content in seed and also on the oil and protein yields in sunflower. Irrigation scheduled once each at seedling, buttoning, flowering and seed developing stages recorded significantly highest values of seed yield and its attributes and seed protein content and its yield. Except the significantly highest (5.21 q/ha) oil yield by Kaolin during 2000, the application of various antitranspirants had no significant effect either on seed yield and its attributes or biochemical parameters. Interaction effect between irrigation dates and antitranspirants was also non-significant..
