“…However, in typically Mediterranean climate, seasons may be either mild and wet or extremely dry. In our study, in 2008, seed filling fell during a period characterized by high temperatures and drought, affecting yield components, and as consequence seed production, as already stated by other authors [4,56] in their studies in Mediterranean-type climate.…”

“…Moreover, oilseed rape cultivation fits well with crop rotations based on winter cereals in Mediterranean-type environments. Oilseed rape might be also considered a valuable option from an economic point of view compared to other grain crops [2][3][4]. The recent establishment of oilseed processing plants have strengthened the interest in oilseed rape production in southern Europe [5][6][7][8].…”

Low-Input Herbicide Management: Effects on Rapeseed Production and Profitability

Abstract:The oilseed rape conventional system can be moved to a more sustainable one by reducing herbicide application whilst ensuring at the same time effective weed control, maintaining oilseed rape yield, and quality and increasing profitability. Over three growing season periods, two field experiments at two different Southern Italy locations were carried out. In both sites, a conventional weed-control management system (recommended label dose), four alternative low-herbicide treatments, and an untreated control were compared. We monitored weeds and crop response to herbicide treatments, and calculated the net economic return, within site and year, for each treatment. In experiment 1, a half dose of herbicide did not show any significant difference in seed yield with respect to conventional treatment in two of three growing seasons. In experiment 2, compared with the conventional system, weedy control and the lowest applied herbicide dose treatment (25% of the recommended label dose) did not underline significant differences with regard to yield level. Net returns from the half dose of metazachlor herbicide were not significantly lower than net returns from conventional treatment in experiment 1 (on a three-year average 748 vs. 812 € ha −1 , respectively). Our findings suggest that the herbicide dose might be cut by at least 50% in order not to jeopardize negative effects on production and economic performances.

“…Labai svarbus sėjos laikas, kad augalams būtų lengviau adaptuo tis prie konkrečių aplinkos meteorologinių sąlygų. Sėjos laikas yra agrotechnikos elementas, pade dantis augalų veislėms prisitaikyti prie konkrečių meteorologinių sąlygų (Takashima et al, 2013). Kaip nurodo E. J. Boothas ir F. D. Gunstone'as (2004), optimalus vasarinių rapsų sėjos laikas priklauso nuo dirvožemio ir numatomų derliaus nuėmimo sąlygų.…”

Esminis kenkėjų sumažėjimas nustatytas rapsus pasėjus gegužės mėn., palyginti su balandžio mėn. sėjomis. 2017 m. daugiausia rapsinių žie-dinukų rasta birželio 2 d. sėtame rapsų pasėlyje, vidutiniškai 3,9 karto, palyginti su anksčiau sėtais rapsais, ir 2,9 karto, suvėlinus sėją viena savaite. Manoma, kad žalos padarė maitintis suskridusi žieminių rapsų butonuose išsiritusių žiedinukų karta. 2016 m. nustatytas labai stiprus statistiškai patikimas priklausomumas tarp teigiamų temperatūrų sumos (10 dienų laikotarpis) iki vasarinių rapsų sėjos bei spragių paplitimo pasėlyje (r = 0,98, P ≤ 0,05), taip pat rapsų skilčialapių (BBCH 10-19) pažeidimų intensyvumo (r = 0,92, P ≤ 0,05). Kuo labiau įšilo orai iki rapsų sėjos, tuo anksčiau pasirodė spragės. 2017 m. nustatyti stiprūs koreliaciniai ryšiai tarp kryžmažiedi-nių spragių skaičiaus ir pažeidimų intensyvumo, taip pat pasėlio tankumo praėjus trims dienoms po sudygimo (r = -0,82; P ≤ 0,05; r = -0,89; P ≤ 0,01) ir septynioms dienoms po rapsų sudygimo (r = -0,81; P ≤ 0,05; r = -0,88; P ≤ 0,01).Raktažodžiai: vasariniai rapsai, sėjos laikas, ligos, kenkėjai

“…Taking into account the economic importance of rapeseed, several aspects of cropping have been regularly studied, such as cultivar adaptation (Ozer 2003;Rodrigues et al 2010Rodrigues et al , 2013Rodrigues et al , 2014Takashima et al 2013), response to N fertilizers (Rathke et al 2005;Németh et al 2009;Rodrigues et al 2010;Li et al 2015;Kuai et al 2016;Gu et al 2017), date of sowing (Johnson et al 1995;Ozer 2003;Rodrigues et al 2013;Sieling et al 2017), and planting density (Leach et al 1999;Zang et al 2012;Wang et al 2015;Kuai et al 2016). However, the performance of the crop when grown in warmer and drier climates as a response to such cropping conditions is less well known.…”

Rapeseed acreage has been increasing fast in the last few decades and cultivated areas have expanded into lower latitudes because of the high value of its seed. This work evaluates the effect of date of sowing and nitrogen (N) fertilization on crop productivity and N use efficiency in a Mediterranean environment. The experiment was arranged in a split-plot design with the dates of sowing as the main-plots and N rates the sub-plots. Rapeseed recovered 128 to 212 kg N hm -2 before top-dress N application in late winter if sown before the last week of September. Seed yield was very dependent on the date of sowing, varying from 3.4 to 6.2 Mg hm -2 on the first sowing date in September to 0.3 to 1.0 Mg hm -2 on the last sowing date in November. The daily loss in seed production was 68.9 kg hm -2 (or 482.3 kg hm -2 per week) or 1.53 % (or 10.7 % per week). N rate significantly increased seed yield within each sowing date but did not allow latesowed plants to regain the productivity levels of those sown earlier. Apparent N recovery and agronomic N efficiency were particularly dependent on the growing conditions associated to different sowing dates. ARTICLE HISTORY
