“…Cool and moist weather with 19-23 ºC temperature are critical environmental factors for disease development and spread (Luong et al, 2010). These findings are in agreement with earlier report that low mean air temperatures (12.2-21.7 ºC), high relative humidity (61.0-79.3%) and rainfall affect the spread and severity of Sclerotinia stem rot disease in winter oilseed rape crop (Brazauskiene et al, 2013). However, flowering in pigeonpea occurred during December at Pusa, Bihar (India).…”

The incidence of Sclerotinia rot disease was recorded on various pigeonpea cultivars from flowering initiation to pod formation stage during the years 2012-13 and 2013-14. Critical symptoms of the disease were observed as formation of cottony white mycelium along with number of sclerotia on infected tissues. The pathogen was characterized on the basis of morphological and pathological traits. The cool wet winter with average minimum and maximum temperatures (9.2 and 21.0 ºC) and more than 93% relative humidity play an important role for stem rot disease development and spread in pigeonpea crop. The pigeonpea cultivar, 'ICPL-151' showed maximum disease incidence, twig infection and yield losses up to 73.35%, 23.58% and 15.70%, respectively, while 'Kudrat' and 'MAL-13' cultivars were found completely resistant to the disease.

“…At present, the main goals of oilseed rape breeding are to-(i) increase yields, mainly in hybrid cultivars [11]; (ii) improve agronomic traits, mainly resistance to pre-harvest seed shattering [12], drought [13], high/low temperature [14,15], soil salinity [16] and lodging [17]; (iii) increase resistance to disease and pests [18,19]; (iv) decrease the content of biologically active compounds that compromise the feed value of non-fat seed residues [20]. The introduction of winter oilseed rape cultivars with a determinate growth habit was important from a commercial perspective [10].…”

A Multi-Criteria Evaluation of the Effectiveness of Nitrogen and Sulfur Fertilization in Different Cultivars of Winter Rapeseed—Productivity, Economic and Energy Balance

This article presents the results of a three-year experiment involving a multi-criteria evaluation (productivity, economic and energy balance) of the effectiveness of nitrogen (N) and sulfur (S) fertilization in different cultivars of winter oilseed rape (open-pollinated, semi-dwarf hybrid, long-stem hybrid) grown in north-eastern (NE) Poland. The yield of the semi-dwarf cultivar was 11% lower than the yield of the long-stem hybrid cultivar and 18% higher than the yield of the open-pollinated cultivar. In all cultivars, N fertilization improved yields up to a rate of 180 kg ha−1 and up to a rate of 230 kg ha−1 in years with low precipitation in spring and summer. Seed yield increased in all cultivars in response to S fertilization at 40 kg ha−1. Higher rates of N fertilizer decreased the content of crude fat and glucosinolates (GLS) and increased the concentration of total protein in all cultivars. Sulfur fertilization increased the content of total protein (in long-stem cultivars) and GLS (in all cultivars). Production costs ranged from €542–624 ha−1 (≤130 kg N ha−1) to €619–697 ha−1 (≥180 kg N ha−1). The demand for energy in the production of winter rapeseed ranged from 14.5–19.3 GJ ha−1 (≤130 kg N ha−1) to 22.4–27.0 GJ ha−1 (≥180 kg N ha−1).

“…This problem can be addressed by reversing soil fatigue through the introduction of new cultivars and technologies suited to their requirements. The registered open-pollinated and hybrid cultivars of rapeseed differ significantly in their agricultural and functional characteristics, as well as in their responses to agricultural treatments, and soil and climatic conditions (Brazauskienė et al 2013). Winter rapeseed is one of the most demanding crops with regard to fertilization rates and agricultural practices.…”

In a field experiment, winter rapeseed was grown in 5-year monoculture and in crop rotation (winter rapeseed, winter wheat, field peas, spring wheat and winter rapeseed). Two open-pollinated cultivars (Californium and Castille) and one hybrid cultivar (Nelson) were compared in systems with three levels of agricultural inputs, low input, medium input and high input, characterized by different rates of nitrogen and sulfur fertilization and pesticide use. The severity of sclerotinia rot (Sclerotinia sclerotiorum) and verticillium wilt (Verticillium spp.) on plants, dark spot (Alternaria spp.) and grey mold (Botrytis cinerea) on leaves and pods, as well as dry rot (Phoma lingam) on stems was evaluated during the growing season. The yield of winter rapeseed was calculated. Rapeseed grown after a 4-year break was characterized by less severe symptoms of dark spot on leaves and dry rot on stems, but more severe symptoms of grey mold on leaves and pods. The severity of dark spots on rapeseed pods (in crop rotation) was reduced with an increase in agricultural inputs. Cultivars Californium and Nelson were generally rarely infected by Verticillium spp., their leaves were less infected by Alternaria spp. and stems by Phoma spp. Nelson was the highest-yielding cultivar.
