Sampling Problems

The response of three spring cultivars of oilseed rape to five levels of nitrogen fertilizer (0 to 200 kg/ha) was studied during 1978–9 (Scarisbrick, Daniels & Alcock, 1981). Sampling problems, practical difficulties of measuring yield components, and the high co-efficients of variation for these data were discussed. During the course of further investigations on the winter cultivar Jet Neuf (established on approximately 75000 ha in the U. K. during 1980–1) within-plot variability for plant weight was assessed in order to indicate the size of sample necessary to compare treatment means.

Rhizoctonia Cerealis

It has long been known that the size and shape of sampling units used to assess crop yield may have significant effects upon the precision of the estimates (Smith, 1938; Hudson, 1939) but little is known about the effects when estimating incidence of disease. Gilligan (1980) showed that estimates of the incidence (i.e. presence or absence of disease) of stem canker (Phomx, lingam, perfect state Lepto sphaeria maculans)of oil-seed rape were more precise when large square sampling units rather than long rectangular units of similar area or small square sampling units were used. Moreover, estimates derived from the frequently used method of sampling by removal of 25 stems, supposedly at random from each plot, were shown to be biased.

Abstract A description is provided for Cylindrosporium concentricum[Pyrenopeziza brassicae]. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Brassica spp. (cabbage, cauliflower, broccoli, brussel sprouts, oil seed rape, swedes). DISEASE: Light leaf spot of Brassicae. GEOGRAPHICAL DISTRIBUTION: Europe (UK, Ireland, Netherlands, Germany, Denmark, Norway, Portugal, Rumania, Latvia); Asia (Japan, Philippines); Australia (South Australia, Tasmania); New Zealand. (CMI Map 193, ed. 2, 1975). TRANSMISSION: By splash-dispersed air-borne conidia. No seed transmission has been demonstrated.

Important Disease

The polyphagous pathogen Sclerotinia sclerotiorum (Lib) de Bary causes significant diseases of sunflower and oil-seed rape while Diaporthe wilt, invoked by the pathogen Diaporthe (Phomopsis) helianthi Munt-Cvet. et al., is another important disease of sunflower in Slovakia. Since 2001 we have identified S.  sclerotiorum on Iva xanthiifolia Nutt. in three locations and the infestation of I. xanthiifolia by D. helianthi  has been observed only in one location of western Slovakia. The infestation of I. xanthiifolia by Sclerotinia disease and by D. helianthi has been observed only after secondary ascospore infection in sunflower fields.

Growth Development

SUMMARYThe growth and development of single plants of oil seed rape, variety Zollerngold, are described quantitatively and particular attention paid to the sequence and pattern of flower and pod production on the different inflorescences. The period of flower opening over the whole plant spanned an average of 26 days and more than 75% of the pods which were retained to maturity were formed from flowers which opened within 14 days of anthesis. Most of these flowers were found on the terminal raceme and on the basal and middle regions of the axillary inflorescences arising from the uppermost three nodes.
