Abstract

To study the effect of planting date (at the SECOND CROPPING) SUNFLOWER on YIELD and its components a split plot design based on complete randomized block design with 3 replications an experiment was carried out in W. Islamabad Research Station in 2010. Planting dates consisting 10th, 26th June and 11th July and new HYBRIDs consisting CMS 19´R43, SHF-81-85, SHF-81-90 and Allstar was located as main plots and subplots, respectively. Analysis of variance showed traits leaf area index, head diameter, head seed number, thousand seeds weight, seed YIELD, oil percent and oil YIELD at different planting date’s hade a significant difference. HYBRIDs considered for traits such as leaf area index, head diameter, head seed number, thousand seeds weight and oil YIELD showed a significant difference. Leaf area index, head diameter, thousand seeds weight, seed YIELD, oil percentage and oil YIELD in the first planting date (10th June) and the third planting date (11th July) showed the highest and lowest rates, respectively. First and third planting dates with 4244.7 kg/h and 2978 kg/ha, respectively, had highest and lowest of seed YIELD amounts. Interaction effects of the planting date ´ genotype were different significantly for head diameter, thousand seeds weight and oil YIELD. CMS 19´R43 and SHF-81-90 HYBRIDs in the first planting date with 1817 and 1795 kg/ha showed greatest oil seed YIELD. We conclude that the first planting date due to the all traits is the best planting date.
