SummaryAn experiment was conducted during the rabi seasons of 1980–1 and 1981–2 to study the effect of exchangeable sodium percentage (ESP) of 87, 62, 44, 34 and 27 on growth, yield and chemical composition of toria (Brassica campestris var. Toria), raya (Brassica juncea L.) rapeseed (Brassica campestris var. Brown Sarson) and taramira (Eruca saliva). Number of branches per plant, number of siliquae per plant and seed yield of these crops were highest at 27 ESP. Increasing ESP decreased N, P, K, Ca, Mg, Fe, Zn, Cu and Mn concentrations and decreased that of Na in seed and stover. These crops can be grown successfully up to about 44 ESP without significant reduction in yield. Raya and rapeseed produced higher yields than the other oilseed crops on sodic soil.

This paper describes the communities of weeds in cereal and oilseed crops in Saskatchewan, using data collected in a 4-yr survey that sampled more than 400 fields. The survey data for the 40 most common weeds were analyzed in an attempt to distinguish natural groups of weed species and to compare the weed communities associated with the different crops and with different soils. The crops were barley (Hordeum vulgareL.), flax (Linum usitatissimumL.), oats (Avena sativaL.), rape (Brassica campestrisL.,Brassica napusL.), and wheat (Triticum aestivumL.). Phytosociological association and cluster analysis indicated that the associations of the weed species were more or less independent of the crop, although some differences existed and were determined more by soil or the associated climate. The 40 most common species were divided into three groups related to the soil and climatic subregions of the province.

Seeding Date

The effects of seeding data and nitrogen and phosphate fertilizer on the agronomic characteristics of two rapeseed species (Brassica campestris L. and B. napus L.) were studied for a 6-yr period at two northwest Alberta locations. Seeding dates were established at weekly intervals from early May to mid-June. Two fertility levels were established; a control treatment in which no fertilizer was applied and a fertilizer treatment in which nitrogen and phosphorus were applied to meet the requirements of a 1680 kg∙ha−1 crop. Maximum yields were obtained most frequently with seeding periods of mid- to late May for B. campestris and mid-May for B. napus. Seeding date had little effect on plant density or seed quality. Nitrogen and phosphate fertilizer reduced plant densities but increased seed yield where nutrient deficiencies occurred.Key words: Brassica campestris L., B. napus L., seeding date, yield, quality
