Pest categorisation of Coccus viridis

EFSA Journal, Volume 23, Issue 7, July 2025.
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Coccus viridis (Hemiptera: Coccidae), the green coffee scale, for the territory of the European Union (EU), following the commodity risk assessment of Jasminum polyanthum from Uganda, in which C. viridis was identified as a pest of possible concern to the EU.

Studies on Genetic Variability in Gerbera (Gerbera jamesonii)

International Journal of Bioresource Science, 2015
An a empt was made to study the extent of genetic variability present in gerbera grown under protected conditions in mid-hills of West Bengal. The values for GVC, in general, were in closer proximity to that of PCV for almost all the characters indicating that these can be utilized in breeding programme.

Impact of substrate pH and micronutrient fertility rates on Cannabis sativa

Agrosystems, Geosciences &Environment, Volume 8, Issue 1, March 2025.
Abstract Micronutrient accumulation caused by low pH can lead to toxicity and have detrimental impacts on plant growth. In substrates with elevated pH, micronutrients become less available. In the first experiment, industrial hemp (Cannabis sativa L.) growth was less at pH 3.0 and 4.0 than when pH was ≥5.0. Root growth was also observed to be inhibited
