“…It can also be used as a vegetal covering of the soil, being the species most cultivated in the country Brassica napus L. var. oliferous, where its late cultivation in winter could contribute to optimizing the use of agricultural resources further, also creating another income opportunity for farmers (Milciades et al, 2014).…”

Agriculture depends on biotic and abiotic factors, and one of them is allelopathy, defined as the chemical interference that one plant has on others, which can negatively affect germination. The objective of this work is to evaluate the allelopathic effects of Sorghum bicolor and Digitaria insularis on seed germination and initial development of canola seedlings (Brassica napus L.). A completely randomized design was used in a 2x5 factorial scheme (two extracts: D. insularis and S. bicolor) and five concentrations (0, 25, 50, 75, and 100%), with four replicates of fifty seeds, the plot being constituted by a 'gerbox' box containing 50 seeds evenly distributed. The variable analyzed were germination percentage (G), abnormal seedlings (AS), dead seeds (DS), length of the shoot (SL) and primary root (RL), total length (TL) of the seedling, shoot ratio (S/T), and root ratio (R/T). The aqueous extracts of D. insularis interfere in all variables studied, which compromises the formation of normal seedlings, regardless of concentration. The extract of S. bicolor expressed allelopathic effects only in concentrations above 75%. Both species can inhibit the initial development of canola plants.

In Brazil, the cultivation of canola has increased as a result of higher demand for biodiesel production. However, the current knowledge on planting arrangement and sowing time to boost the crop's yield in the southern part of the country is limited. On this point, the goal of this work was to evaluate the yield potential of four canola hybrids submitted to different sowing dates and inter-row spacings in 2011 and 2012 crop years in Maringá, city located in the Brazilian state of Parana's Northwest area. The experiment was conducted with 16 treatments constituted of 2 sowing dates (April 08 and May 10), 2 inter-row spacings (0.17 and 0.45 m) and 4 hybrids (Hyola 76, Hyola 61, Hyola 433 and Hyola 411). The experimental design was a randomized complete block design with the treatments in a split-split plot design with four replications in the field. The yield potential of each hybrid was evaluated through the weight of a thousand seeds, the grain yield, and the oil content. From the results of grain and oil yields found, the canola hybrid Hyola 433 showed stable production in both crop years and, therefore, are indicated for sowing in early May. On the other hand, Hyola 61 and Hyola 71 can be recommended for sowing in early April. Mostly, the evaluated inter-row spacings did not affect the grain and oil yields over the two crop years.

“…The mean lipid value expected in Brazil is 380 g kg -1 [6]. In Cfa climate, varying sowing dates, [16] obtained, for two hybrids, values between 346 and 399 g kg -1 .This variation, according to the authors, was correlated with water stress.…”
