Abstract
A field experiment was conducted at ARS, Bhavanisagar, during summer 2021, to investigate the effect of multi-nutrient-loaded electrospun PVA nanofibre on the green gram. The nanofibre developed from polyvinyl alcohol (10%) infused with macro and micronutrients. The nanofibre coated seeds recorded the higher plant height (44.97 cm); crop growth rate (1.5- 18.43 g m-2 d-1); leaf area index (0.56-1.84 m2m-2) and leaf area duration (13.29-34.77days). Further, the higher grain yield (854.2 kg ha-1) and haulm yield (1100 kg ha-1) were obtained from the nanofibre-coated seeds. According to the findings of this study, nanofibre technology is a novel idea for the fertilizer sector because it reduces fertilizer use and increases nutrient use efficiency.

Fusarium oxysporum is a common pathogen present in various environments, both in plant tissues and rhizosphere soil
This study focuses on identifying the volatile organic compounds (VOCs) produced by several macrobasidiomycete fungi and their potential inhibitory activity towards F. oxysporum f.sp. lycospercisi
We found that the volatiles produced by mycelia of Coprinus cinereus significantly inhibited 70 % mycelial growth of F. oxysporum f.sp. lycopercisi, followed by G. lucidum(60.28 %) and L. edodes (35.28 %), over control (Fig. 2)
Summary
Fusarium oxysporum is a common pathogen present in various environments, both in plant tissues and rhizosphere soil. It is a soil-borne pathogen widely distributed in majority of vegetable and fruit crops. F. oxysporum express both pathogenic and non-pathogenic mode of infection. Plant pathogenic form of infection is defined by its strict host specificity (Arie et al 2007 and Arie, 2010). Tomato is infected by Fusarium wilt caused by F. oxysporum f.sp. Various attempts have been made to control plant diseases by eradication or prevention through the use of synthetic fungicides. Biological control of plant pathogens promotes disease suppression
