Effect of Glyphosate, Salicylic Acid, Nitrogen and Organic Fertilization on Broomrape Control and Faba Bean Productivity

Abstract

In Upper Egypt, the level of broomrape infestation is so high because of high temperature which led to decline of faba bean area. The control of two field experiments were conducted in a heavy infested soil with broomrape inShandaweel Research Station, Sohag Governorate, Agricultural Research Center during 2016/17 and 2017/18 winter seasons to study the effected potential integration between nitrogen and manure fertilizers hand pulling and interaction between selective herbicides and salicylic acid on control for broomrape and increased faba bean productivity. Each experiment contained three levels of (nitrogen fertilization at rate 20 kg/fed., organic manure fertilizers at rate 20 m 3 /fed, nitrogen fertilization at rate 10 kg /fed + organic manure fertilizers at rate 10 m 3 /fed and without fertilizer (untreated check) and eight broomrape control treatments (Glyphosate twice at rate 75 cm 3 /fed -Glyphosate once at rate 75 cm 3 /fed. + Salicylic acid once at 200 mg/one liter water -Glyphosate once at rate 50 cm 3 /fed + Salicylic acid once at 200 mg/one liter water -Salicylic acid thrice at rate 200 mg/one liter water -Hand pulling twice and untreated (control). Split plot design in three replications were used. Faba bean cultivar was Giza -843 and plot area was 10.5 m 2 . The results revealed that fertilizers reduced significantly Orobanche infestation in 2016/17 and 2017/18 seasons. Addition of 20 kg N-fertilizer/fed and N-fertilization at 10 kg /fed + O.M-fertilizers at 10 m 3 /fed increased number plants of faba bean/plot by (10.28 & 6.84%) and (2.84 & 1.18%), decreased number of plant infestation/plot by (33.41 & 17.40%) and (13.86 & 10.58%), number of broomrape spikes /plot by (31.49 & 22.16%) and (15.44 & 12.83%) and dry weight broomrape spikes/plot by (31.38 & 22.00%) and (15.45 & 12.84%) in 2016/17 and 2017/18 seasons, respectively, compared with non-fertilizer check. Nitrogen fertilization and nitrogen fertilization +Organic manure fertilizer recorded the highest values for plant height (cm), number of branches/plant, number of pods/plant, weight of pods/plant (g), seed weight/plant (g), 100-seed weight (g) and seed yield /fed in both seasons compared with non-fertilizer. Broomrape control treatments decreased significantly numbers and weight broomrape spikes (g/plot) of Orobanche in 2016/17 and 2017/18 seasons. Glyphosate at rate twice at 75 cm 3 /fed and Glyphosate once at rate 75 cm 3 /fed. + Salicylic acid once at 200 mg/one liter water increased number plants of faba bean/plot by (12.44 & 12.35%) and (4.61 & 4.12%) and decreased the number of plant infestation of faba bean/plot by (59.43 & 46.69%) and (52.52 & 51.54%), number of broomrape spikes /plot by (55.06 & 50.64%) and (49.63 & 49.48%) and dry weight of broomrape spikes/plot by (55.10 & 50.69%) and (49.62 & 49.47%) in 2016/17 and 2017/18 seasons, respectively, as compared with untreated (control). Glyphosate at rate twice and glyphosate once + Salicylic acid once gave the heist values number of pods/plant, weight of pods/plant (g), seed wei...

Response of Faba Bean to Foliar Spraying with Chelated Iron under different Nitrogen Fertilization Treatments in Sandy Soils

“…Confirming results were emphasized by Sadek (2010), Gad et al (2011), Abou-Elela and Gadallah (2012), Mohamed et al (2013), Fouda et al (2015), Sherif et al (2017) and Abd El-Haleem et al (2019). Faba bean plants received 60 Kg N/fad outweighed significantly those treated by 40 Kg N /fad plus spraying with 1% urea in weight of pods and seeds per plant, the last treatment deviated in this respect significantly with 40 and 20 Kg N /fad and that was true in the two seasons (Table 2).…”

“…Several investigators recorded that applying nitrogen fertilization increased seed yield per fad of faba bean, Shaaban et al (2006), El-Howeity et al (2009, Sadek (2010), Gad et al (2011), Abou-Elela and Gadallah (2012), Mohamed et al (2013), Abou-Amer et al (2014), Fouda et al (2015 and Abd El-Haleem et al (2019).…”

“…The positive effect of supplying faba bean with nitrogen fertilization on yield, its attributes and yield quality were emphasized by Fathy et al (2007), El-Howeity et al (2009), Osman et al (2010), Sadek (2010), Gad et al (2011), Abou-Elela and Gadallah (2012), Ghalwash et al (2012), El-Tantawy and Nawar (2013), Mohamed et al (2013), Abou-Amer et al (2014), Ashoori (2014), Fouda et al (2015), Sherif et al (2017) andAbd El-Haleem et al (2019).…”

the Diversity of Lepidopteron pests and assessing their infestation ratios and damages on cruciferous crops

“…sampling for infestation percentages was taken at two growing period ; first was at leaf stage one month after transplanting and the second was flower or head formation, of crop depending on the presence of larval stage on the plants, for this, the total number of plants contained in each of the three replications were checked for each crop varieties. Infestation percentage for each insect pest was worked out by using the following Formula (Equation 1) (El-Haleem et al, 2019).…”
