Determination of moisture and oil in the seed of winter rape (Brassica napus) II.‐Comparison of extraction methods for the estimation of oil
TLDR
In this paper, the rate of oil extraction from moist and dry rape seed was compared over an extraction time of 20 h and showed oil to be more readily extractable from oven-dried seed.Abstract:
The rate of oil extraction from moist and dry rape seed was compared over an extraction time of 20 h and showed oil to be more readily extractable from oven-dried seed. Three methods of determining the oil content by extraction of single samples were compared with a method in which a number of samples contained in single satchets were extracted in one large extractor. No significant differences were shown between any of the methods used, and it is proposed where sample numbers are large, and oil content is the only analysis required, that the multiple extraction method of oven-dried seed is satisfactorily quick and accurate.read more

A quantitative analysis of the effects of nitrogen on the growth, development and yield of oilseed rape
E. J. Allen,D. G. Morgan +1 more
TL;DR: Crop growth rates were increased by the application of nitrogen and reached their highest levels during the period of pod development when the leaf areas had declined to very low levels, suggesting that the maintenance of a large and photosynthetically efficient leaf area during theperiod of flowering is necessary for high yields in this crop.

A quantitative comparison of the growth, development and yield of different varieties of oilseed rape
E. J. Allen,D. G. Morgan +1 more
TL;DR: The results suggest that the rate of supply of carbon assimilates to the inflorescences around the time of anthesis is an important yield-determining character in oilseed rape varieties.

Effects of sowing date on the growth and yield of winter oil-seed rape (Brassica napus)
P. D. Jenkins,D M. H. Leitch +1 more
TL;DR: It is suggested that early spring growth, delayed flowering and reduced reflexion of radiation during flowering were important factors leading to the high yields achieved by late sowings in an environment with mild winters and early springs.

Oil determination of oilseed. Gravimetric routine method
TL;DR: In this paper, a method for the determination of oil on long series of oilseed is presented, which is a gravimetric method which reduces the hand labor to a minimum, and the difference between averages for the new method and averages of extraction analyses made with continuous extractors did not exceed 0.28% of oil.
