Global mRNA profiling reveals the effect of boron as a crop protection tool against Sclerotinia sclerotiorum.

Sclerotinia sclerotiorum, the causal agent of white mould, is a necrotrophic fungal pathogen responsible for extensive crop loss. Current control options rely heavily on the application of chemical fungicides that are becoming less effective and may lead to the development of fungal resistance. In the current study, we used a foliar application of boron to protect Brassica napus (canola) from S. sclerotiorum infection using whole-plant infection assays. Application of boron to aerial surfaces of the canola plant reduced the number of S. sclerotiorum-forming lesions by 87 % compared to an untreated control. Dual RNA sequencing revealed the effect of boron on both the host plant and fungal pathogen during the infection process. Differential gene expression analysis and gene ontology term enrichment further revealed the mode of action of a foliar boron spray at the mRNA level. A single foliar application of boron primed the plant defence response through the induction of genes associated with systemic acquired resistance while an application of boron followed by S. sclerotiorum infection-induced genes associated with defence response-related cellular signalling cascades. Additionally, in S. sclerotiorum inoculated on boron-treated B. napus, we uncovered gene activity in response to salicylic acid breakdown, consistent with salicylic acid-dependent systemic acquired resistance induction within the host plant. Taken together, this study demonstrates that a foliar application of boron results in priming of the B. napus plant defence response, likely through systemic acquired resistance, thereby contributing to increased tolerance to S. sclerotiorum infection.

Foliar application of agrochemicals enhance growth, productivity, quality and biochemical traits of soybean

Flower drop, senescence of flowers and inadequate pod filling pose significant challenges in soybean cultivation as rapid nutrient extraction from leaves during the reproductive stage accelerates leaf aging. The present study assessed the effect of foliar application of agrochemicals on growth, productivity, quality and biochemical traits of soybean at two locations during kharif (rainy) season of 2021 and 2022. The experiment comprised of ten treatments of foliar application of agrochemicals [absolute control, water spray, potassium nitrate (KNO3) 1.5%, NPK (19:19:19) 1.5%, boron 0.3%, ammonium molybdate (AM) 0.5%, thiourea 750 parts per million (ppm), urea 2.0%, muriate of potash (MOP) 0.5% and salicylic acid (SA) 100 ppm] at flower and pod initiation stages along with the recommended dose of fertilizer (RDF) in a randomized complete block design replicated thrice. Results revealed that foliar application of boron 0.3%, urea 2.0% and MOP 0.5% at Ludhiana and MOP 0.5%, potassium nitrate 1.5% and urea 2.0% at Ballowal Saunkhri increased growth (plant height and dry matter accumulation), yield attributes (number of pods plant−1, number of filled pods plant−1 and 100-seed weight) and seed yield. These agrochemicals showed positive effects on the biochemical parameters with increased levels of proline and total phenol content as well as improvements in total soluble sugars, starch and protein content. The findings suggest that foliar application of agrochemicals (boron 0.3%, urea 2.0%, MOP 0.5% and potassium nitrate 1.5%) along with RDF can improve soybean growth and seed yield by mitigating the nutrient stress at reproductive stages.

Impact of Foliar Application of Boron on Yield and Yield Attributes, Assimilate Supply, Production Efficiency and Fertilizers Productivity of Indian Mustard (Brassica juncea) in Field Experiments

Field experiments were conducted for three consecutive rabi seasons from 2018 to 2020 to assess the impact of foliar application of boron fertilizer on yield and yield attributes, assimilate supply, production efficiency and fertilizers productivity of Indian mustard [Brassica juncea (L.) Czern. &Coss.]. The results showed that the number of primary branches/ plant (7.00 to 8.08), number of siliquae/plant (427.2 to 468.8), number of seeds/siliqua (13.03 to 14.01), test weight of seed (3.60 to 3.80 g) and plant dry matter production (38.10 to 41.20 g/plant) were significantly increased with T2 treatment (100% NPKS + foliar application of Boron @ 0.5% Borax) as compared to farmer’s practice T1 (100% NPKS + without boron) during three years of experiments. Significantly higher seed yield (22.5 to 24.7 q/ha) of the mustard crop was also reported with T2 (100% NPKS + foliar application of Boron @ 0.5% Borax) as compared to farmers’ practice T1 (100% NPKS + without boron) (seed yield 19 to 22.5 q/ha) during the studies. Similarly, Treatment T2 resulted in significantly higher production efficiency and assimilates supply of mustard crop than that of T1 (farmer’s practice). The fertilizer productivity in the mustard crop that is directly related to seed yield and the partial factor of productivity of N, P, K and S fertilizers (PFPNPKS) were also increased significantly with the T2 compared to farmers practiceT1(farmer’s practice), during 3 years of studies. The highest gross return and net return and benefit-cost ratio were obtained with T2 (100% NPKS + foliar application of Boron @ 0.5% Borax) treatment over T1 (100% NPKS + without boron).

Boron Impact on Maize Growth and Yield: A Review

Maize (Zea mays L.) is a vital crop, contributing significantly—at least 30%—to global dietary energy intake and biofuels and ethanol production. This review article delves into the dynamic interplay between boron (B) and maize growth, yield, and agricultural sustainability. Boron, a crucial micronutrient, is pivotal in essential physiological processes such as root development, leaf expansion, and cob formation. These processes are fundamental for ensuring the vigour and productivity of maize crops. Conversely, boron deficiency manifests as thinner leaves with reduced chlorophyll content, compromising plant health, and hindering yield potential. Maintaining adequate boron levels, particularly during reproductive stages, is critical for mitigating the risk of abnormal ears and maximizing the quantity and quality of maize production. Emerging research underscores the significance of foliar boron application at various growth stages of maize, which stimulates growth, facilitates cell wall development, and increases leaf area. This translates to improved light interception and photosynthetic efficiency, ultimately contributing to increased plant vigour and biomass accumulation. Furthermore, exploring innovative approaches for sustainable boron management is crucial. This includes precision fertilization techniques and biofortification strategies to ensure optimal maize production while minimizing environmental impacts. By gaining a deeper understanding of the complex relationship between boron and maize, farmers can develop customized fertilization plans that utilize strategic foliar boron application. This approach unlocks maize's full yield potential and contributes to sustainable agricultural practices, supporting global food security.
