Abstract

In order to investigate the effects of different TILLAGE METHODS on agronomic performance of sunflower (Helianths annus L) varieties in a double cropping system after winter barley, a two year experiment was conducted during 1999-2000growing seasons in research farm, faculty of Agriculture, University of Shahid Bahonar, Kerman. Experimental design was split plot with four replications. Treatments were different combination of 3 SUNFLOWER VARIETIES: Zaria, Record, and Azargol (CMS19 x R43) as main plots; and 3 TILLAGE METHODS; a: no tillage (NT); b: minimum (Conservation) tillage (MT);c: Conventional tillage (CT) as sub plots. Results showed that sunflower seed YIELD was significantly affected by TILLAGE METHODS and varieties. Azargol hybrid showed higher YIELD in no till and conservation till treatments. Head diameter was significantly affected by TILLAGE METHODS and varieties. Azargol had highest head diameter. Seed numbers / head declined significantly in no – till treatments. 1000 seed weight was most significantly different in Record and Azargol in all TILLAGE METHODS; but this trait was declined in no till treatment in 3 varieties. Seed oil (%) was not significantly different in different varieties and TILLAGE METHODS. However, results indicated that sunflower as second crop after barley; Azargol as a convenient variety, and conservation tillage as well as conventional tillage; could be used in Kerman.
