One of the critical issues in using micronutrient fertilisers is comparison methods and amounts fertiliser use, which very important from aspect increasing production economic viewpoint. The aim this research was to analyse nutrient composition different parts maize (Zea mays L. FAO 490) during growing season with six-level nitrogen fertilisation supplies at five phenological stages. study incl...

Laboratory and pot culture experiments were conducted to assess the acute persistent toxicity of new molecular insecticides against notorious invasive pest maize, Spodoptera frugiperda during 2020- 2021 at Department Agricultural Entomology, Tamil Nadu University, Coimbatore. Results revealed that, LC50 value emamectin benzoate, chlorantraniliprole, spinetoram, flubendiamide novaluron 0.05, 4.0...

The application of fertilizers as a topdressing in maize raises serious concerns because too much fertilizer is retained the upper leaves, causing burning to tissues. In this study, use controlled-release and stabilized (with 3, 4-dimethylpyrazole phosphate) was compared with conventional split into two equivalent applications forage maize-oats cropping system. maize, 100 200 kg N ha−1 differen...

It is a challenge to breed maize (Zea mays L.) varieties with enhanced levels of protein, oil, starch, and essential amino acid contents while maintaining competitive agronomic capability. We used multivariate statistical procedures to quantify total diversity and its components for 31 physical, biochemical, nutrient, and color traits of 1348 accessions from 13 maize populations. The germplasm ...

The improvement of agronomic practices and the use of high technology in field crops contributes for significant increases in maize productivity, and may have altered the dynamics of nutrient uptake and partition by the plant. Official recommendations for fertilizer applications to the maize crop in Brazil and in many countries are based on critical soil nutrient contents and are relatively out...

Phytoalexins constitute a broad category of pathogen- and insect-inducible biochemicals that locally protect plant tissues. Because of their agronomic significance, maize and rice have been extensively investigated for their terpenoid-based defenses, which include insect-inducible monoterpene and sesquiterpene volatiles. Rice also produces a complex array of pathogen-inducible diterpenoid phyto...

Pathogenic fungi drastically affect plant health and cause significant losses in crop yield and quality. In spite of their impact, little is known about the carbon sources used by these fungi in planta and about the fungal transporters importing sugars from the plant-fungus interface. Here, we report on the identification and characterization of MELIBIOSE TRANSPORTER1 (MBT1) from the hemibiotro...

A few breeding companies dominate the maize (Zea mays L.) hybrid market in Brazil: Monsanto® (35%), DuPont Pioneer® (30%), Dow Agrosciences® (15%), Syngenta® (10%) and Helix Sementes (4%). Therefore, it is important to monitor the genetic diversity in commercial germplasms as breeding practices, registration and marketing of new cultivars can lead to a significant reduction of the genetic diver...
