The effects of time of leaf removal on Brassica napus L. were studied under field conditions at Saskatoon in 1976 and at Swift Current in 1977. Leaf removal at the start of flowering reduced the number of pods per plant, increased seed weight, and reduced seed yield. Leaf removal at the end of flowering did not affect yield or its components.

Rapeseed (Brassica napus L.) is an important alternate oilseed crop in eastern Anatolia, Turkey. No information on plant density for rapeseed is available in this region. Therefore a study was initiated to investigate the effects of spacings between rows and spacings within rows on the yield and agronomic characteristics of two genotypes of spring rapeseed (Tower and Lirawell) in Erzurum, eastern Anatolia, during 1994 and 1995. The effects of spacings between or within rows on the yield and yield components of Tower and Lirawell, two cultivars of Brassica napus L., were studied for 2 years inErzurum,Turkey. Rows were spaced at 15, 30 and45 cm. Spacings within rows were 5, 10 and15 cm. The results of this study suggested that seed yield was significantly affected by spacings between rows but not by spacings within rows, and that rape yields were higher at the narrow (15 cm) row spacing compared to the middle (30 cm) and wider (45 cm) spacings.

An experiment was conducted in Al-zafraniya station / Baghdad – Iraq, during the winter season 2017 - 2018 in order to study the effect of khazra iron nano chelate fertilizer foliar application on two rapeseed varieties for increasing yield and yield components. The experiment designed by randomized complete blocks design (RCBD) for three replicates. The first factor included two rapeseed varieties (Brassica napus var. oleifera and Brassica napus L. var. pactol) and second factor included khazra iron nano chelated in three levels 0, 5 (kg.ha-1) (0.5 kg nano iron fertilizers per 1000-liter water) and 10 (kg.ha-1) (1 kg nano iron fertilizers per 1000-liter water). Means of the treatments was compared with a significant difference in the use of the least significant difference (LSD) at the probability level (p ≤ 0.05). Results showed that effect of khazra iron nano chelate foliar application, rapeseed varieties and interaction of them had significant effects on yield, biological yield and total dry biomass, which were 1298.6 (kg.ha-1), 7900 (kg.ha-1), and 7288 (kg.ha-1) respectively, at level 10 (kg.ha-1) for rapeseed (Brassica napus var. oleifera). While rapeseed (Brassica napus L. var. pactol) only had biological yield and total dry biomass which were 4260 (kg.ha-1) and 4460 (kg.ha-1) respectively. This is due to the genetic nature of each plant species. According to the results, rapeseed (Brassica napus var. oleifera) with 10 kg. ha-1 khazra iron nano chelate fertilizer foliar application had the highest values at most of evaluated characters.
