Effect of Foliar Boron Fertilization of Fine Textured Soils on Corn Yields

Abstract

Boron (B) is an essential micronutrient needed for normal plant growth and development. To evaluate the response of corn to foliar B applications at V4-V6 (4-6 leaves with visible collars) and VT (tasseling) growth stages on fine textured soils, a field experiment was conducted at four sites from 2008 to 2010 in Northeast Missouri. The treatments included a non-treated control; V4-V6 applied B at 0.56, 1.12 and 2.24 kg·ha −1 ; and VT applied B at 0.28, 0.56 and 1.12 kg·ha −1 . Foliar B, applied at V4-V6 at 2.24 kg·ha −1 , resulted in higher yields than VT applications. No significant differences in yield were found for B applications at different timings for concentrations of 0.56 and 1.12 kg·ha −1. Boron applied at V4-V6 and 2.24 kg·ha −1 increased yield 0.29 Mg·ha −1 compared to the non-treated control. The B applications at VT increased ear leaf tissue B concentration compared to V4-V6 applications and non-treated control, but it had no significant effect on corn yields. No significant difference between B treatments was observed for grain oil, protein, starch or extractable starch concentration; severity of anthracnose stalk rot or common rust; and ear tip fill. The B application of 2.24 kg·ha −1 at V4-V6 decreased the severity of gray leaf spot, but increased the severity of northern leaf blight compared to the non-treated control. Boron applied at V4-V6 at 2.24 kg·ha −1 was the most beneficial timing and concentration evaluated in these fine textured soils. OPEN ACCESSAgronomy 2015, 5 2

Effects of a foliar fertilizer containing boron on the development of Sclerotinia stem rot (Sclerotinia sclerotiorum) on canola (Brassica napus L.) leaves

“…Two boron‐based products (Biopaste and Bioshield) containing 5% BA significantly reduced Eutypa dieback ( E. lata ) on grapevines by 78% to 98% in field trials (Rolshausen & Gubler, ) and the boron‐containing products Biopaste and Gelseal, as well as BA, provided effective control of E. lata when applied to the pruning wound on grapevines (Pitt et al, ; Sosnowski, Loschiavo, Wicks, & Scott, ). On corn, foliar applications of boron at 2.24 kg/ha reduced severity of grey leaf spot compared with the non‐treated control in field experiments (Kaur & Nelson, ). Similarly, foliar application of boron (as H 3 BO 3 , at 6.25 mg/L of boron) decreased the number of leaf lesions and severity of tan spot caused by Drechslera tritici‐repentis in winter durum wheat, especially at the booting stage, because boron was involved in physiological and biochemical effects in plants (Simoglou & Dordas, ).…”

Boron Foliar Application in Relation to Sweet Potato Productivity

“…The surface irrigation is used traditionally at this area which could cause boron leaching (Hall, 2008). Limit crop production was reported due to boron deficiency (Kaur and Nelson, 2015;Haytova, 2013). Boron requirements for vegetables are more than in the other crops (Dursun, 2010), and may increase production efficiency and quality (Haytova, 2013).…”

Effects of foliar boron fertilization at early vegetative stages on silage yield and quality parameters of maize

“…Nawaz et al (2017) stated that fresh and dry matter yield of sorghum were increased with increases in boron doses. Kaur and Nelson (2015) indicated that the highest grain yields obtained at 2.24 kg ha -1 boron application at V4-V6 growth stage of maize. Also, Konuskan (2018) reported that boron applications enhanced grain yield of maize at early vegetative growth stages.…”

“…Boron applications can increase maize yield with low quantities (Güneş et al, 2011). Various studies were performed on boron effects on grain yield of maize, previously (Aref, 2011; Kaur and Nelson, 2015;Horuz and Özcan, 2017;Konuskan et al, 2017, Wasaya et al, 2017Nelson and Meinhardt, 2011). However, insufficient researches were performed on boron effects on hay and silage yields and qualities of maize.…”
