Abstract

This study was carried out in 2003 in Karaj region to evaluate the effect of planting date and PLANT DENSITY on yield , yield component and oil percentage of FALL RAPE OIL SEED cultivar (okapi). Treatments were arranged in a completely randomized split - block design with planting date (16 sep, 27 sep , 8 Oct and 18 Oct ) as main plots and PLANT DENSITY (60, 80, 100and120 plant per square meter) as subplots. All treatments were replicated four times. Characteristics such as: plant’s height, number of branches, Dry matter and leaf area index (LAI) during growing season and pod length, number of pod per plant, number of seed per pod, seed YIELD AND OIL PERCENTAGE after harvesting were recorded and statistically analyzed. The results showed that there was a significant difference between all PLANTING DATES except for oil percentage and number of seed per pod, which the first and the second PLANTING DATES (16 sep and 27 sep) were the same and were superior than the third and the fourth PLANTING DATES (8 Oct and18 Oct ). Also the results showed that a significant difference between all treatments of PLANT DENSITY which the first and the second plant densities (60 and 80 p/m2) were the same and were better than the others. Interaction effect of planting date and PLANT DENSITY statistically were significant for plant height and number of pod per plant. Finally it is recommended that for this region and other similar regions superior cultivars be planted at optimum PLANTING DATES (16 Sep to27 Sep) and plant densities (60 and 80 p/m2) in order to increase the quantitative and qualitative yield of oil seed rape.
