“…It was also significantly superior to NP application in seed and straw yields and 1000-seed weight in the two seasons that indicated the necessity of balanced fertilization with the three macronutrients to obtain high economic seed yield of flax. These findings are supported by those reported by Leilah et al (2003), Dordas (2010), Khajani et al (2012) and Bakry et al (2015), who found that adequate supply of nitrogen, phosphorus and potassium enhanced both seed and fiber production of flax. Concerning weed control treatments, data reported in Tables 6 and 7 showed that applied herbicide combinations and hand weeding significantly improved all studied characters, in the two seasons, compared to unweeded check.…”

“…The data also indicate the minor role of phosphorus in maintaining high seed and straw yields of flax even under suppressed weeds conditions. Several researchers emphasized the role of balanced fertilization in flax (Franzen, 2004 andKhajani et al, 2012), whereas others accentuated the role of nitrogen and the necessity of increasing nitrogen use efficiency in flax (Dordas, 2010;El-Nagdy et al, 2010 andRuisi et al, 2016) in order to obtain economical yield under CT or NT systems. On the other hand, several researchers pointed out the lack of response to P application in flax, especially in soils with high P levels (Lafond et al, 2003 andGrant et al, 2008).…”

“…nitrogen, phosphorus and potassium, is essential for enhancing flax growth and productivity. Several researchers reported on the beneficial application of nitrogen (Dordas, 2010 andRuisi et al, 2016), phosphorus (El-Deeb et al, 2006) and potassium (Bakry et al, 2015) either individually or in combination of NP (Lafond et al, 2003) or NPK (Leilah et al, 2003 andKhajani et al, 2012) on productivity of fiber and oil in flax. However, most of the published research reports data were under minimal or zero tillage systems.…”

IntroductionFlax (Linum usitatissmum L.) is grown as a dual purpose crop in Egypt, i.e. for production of fibers and oil. The area devoted for flax production gradually decreased during the last decade to reach 7385 faddans in 2014/2015. That decrease in cultivated area is primarily attributed to increase in production costs, especially inputs related to land preparation and manual labor wages for hand weeding and harvesting. However, production costs could be reduced in the newly reclaimed lands by implementation of no-tillage and application of integrated weed managements for weed control.No-tillage (NT or zero tillage) is a component of conservation agriculture (CA) system, in which seeds are placed into untilled soil by opening a narrow slot, trench, or hole of only sufficient width and depth to obtain proper seed placement and coverage (Derpsch et al., 2014). The S AKHA 4 flax (Linum usitatissmum L.) cultivar was grown in 2013/14 and 2014/15 winter seasons to study the effect of two tillage systems (conventional tillage (CT) vs no-tillage (NT)), macronutrients fertilization (NPK, NP and P) and weed control treatments, i.e. Brominal + Select super, Sinal + Select super, hand weeding twice and unweeded check on weeds and flax productivity at Nubaria Research Station, Agricultural Research Center. The experimental design was split split-plot with 4 replications.Total weeds fresh weight was lower significantly in NT than CT by 17.0 and 18.4%, in the two seasons, respectively. Application of NPK gave higher total weeds fresh weight than NP or P by 6.3 and 20.6% and 8.4 and 20.0%, in the two seasons, respectively, while NP superior P by 15.2 and 12.7%, in the two seasons, respectively. Brominal + Select super was more effective in reducing total weeds fresh weight (98.1 and 97.1%) than Sinal + Select super (92.6 and 92.4%) and hand weeding (93 and 90.7%) compared to unweeded check during the two seasons regardless of the tillage system. No-tillage gave comparable seed yield (1363.7 and 1464.2 kg/ha) to conventional tillage (1562.0 and 1530.1 kg/ha) in the two seasons, respectively. NPK fertilization gave higher values for plant height, number of capsules per plant, 1000-seed weight and straw yield. NPK and NP fertilization increased the seed yield by 57.1 and 51.4% and 69.1 and 50.7%, in the two seasons, respectively, compared to P fertilization treatments.All weed control treatments gave significantly higher values for seed yield and yield components compared to unweeded check, with Brominal + Select super giving a slight increase in the values of those characters compared to Sinal + Select super. Percent increase in seed yield, over control was 71, 69 and 68.5% and 68, 67.5 and 68.4%, for the two seasons, respectively. Correlation analysis revealed negative effect of weeds on flax growth and productivity.The present study indicated that no-tillage was equivalent to conventional tillage concerning productivity of seed and straw from dual purpose flax (for oil and fiber), and the necessity of a balanced fertiliza...

“…The experiments of Hocking et al (1997) did not show a significant effect of increasing nitrogen rates on seed yield of linseed, while Dordas (2010) is of opinion that the nitrogen nutrition status of plants is one of more important nutritional factors that determine the level of yield components. In the study by Strašil and Vorlíček (2004), the application of 60 kg N/ha increased seed yield of linseed by 5.8% compared to the treatment without nitrogen fertilization.…”

“…Zawartość tłuszczu w nasionach nagietka oraz wydajność tłuszczu w zależności od dawki azotu i siarki (średnio w latach 2012-2014) W dostępnym piśmiennictwie dotyczącym nagietka brak jest badań odnośnie wpływu nawożenia azotem i siarką na skład chemiczny nasion. Badania dotyczące innych roślin oleistych wykazały, że intensywne nawożenie azotowe powoduje na ogół zmniejszenie zawartości tłuszczu w nasionach [Dordas 2010, Jiang i in. 2013], natomiast siarka wpływa korzystnie, zwiększając jego udział [Podleśna 2005].…”

Azot i siarka jako czynniki kształtujące plon nasion oraz zawartość i jakość tłuszczu nagietka lekarskiegopotencjalnego surowca olejarskiegoNitrogen and sulphur as determinants of the seed yield, content, and quality of fat in pot marigold -a potential oil sourceStreszczenie. Celem badania było określenie wpływu nawożenia azotem oraz siarką na plon nasion, zawartość oleju i składu kwasów tłuszczowych w nasionach nagietka lekarskiego. Doświadczenie założono w układzie równoważnych bloków z dwoma czynnikami: czynnikiem I rzędu były dawki azotu: 0, 30, 60, 90, 120 kg N·ha . Najlepsze efekty produkcyjne nawożenia azotem uzyskano przy dawkach 60-90 kg N·ha -1. Siarka miała korzystny wpływ na plon nasion oraz zawartość tłuszczu (skuteczność siarki wzrastała wraz z dawkami azotu). Nawożenie azotem modyfikowało skład kwasów tłuszczowych, powodując wzrost zawartości kwasu linolowego i redukcję kwasu oleinowego. Siarka nie wpływała na jakość tłuszczu, natomiast cecha ta w znacznym stopniu zależała od warunków pogodowych w czasie wzrostu roślin i dojrzewania nasion.
