Tomato yellow leaf curl virus (TYLCV) is the most devastating and globally spreading begomovirus (family Geminiviridae). Interestingly, until recently, it has not been reported from South Asia. In the current study, for the first time, we identified a novel strain of TYLCV and associated...

Widespread adoption of efficient irrigation technologies, including drip irrigation, has been proposed to limit groundwater over-exploitation, especially in water-stressed South Asia. This paper evaluates the potential productivity and water-saving benefits of smallholder drip irrigation by...

As a contribution to the lichen flora, two taxa of lichens are reported for the first time. The critical morpho-anatomical comparison and molecular phylogenetic construction based on Internal Transcribed Spacer (ITS-5.8-ITS2) barcode region revealed the identity of two lichenized Ascomycetes ...

Periodic drought is a major challenge in drought-prone areas of South Asia. A sample survey of farmers (n = 400) from South Asia was conducted to study the farmers' perception about drought impacts on their socio-economic status, agro-biodiversity, and adaptation besides public institutions'...

The South Asian agricultural sector has experienced vigorous growth and structural transformation over the last few decades, albeit differently across the region. This study examines the crop diversification status and various determinants, such as socioeconomic (per capita gross domestic product,...

Basal stem rot caused by Ganoderma boninense is the single major disease to affect oil palms in South Asia and Oceania. Although first described in commercial plantations some 90 years ago it remains a major constraint to oil palm planting, with disease occurence increasing with succesive...

The Belt and Road Initiative provides a favorable opportunity for the development of horticultural product trade between China and other countries of South Asia. In order to explore the structure and trend of horticultural products trade between China and eight countries in South Asia, based on the ...

CONTEXT: Intensive cropping and elevated input use to achieve high crop yields have resulted in the injudicious use of resources and a consequent reduction in profit margins for farmers in the Eastern Gangetic Plains (EGP) region of South Asia. In this region rice-wheat (RW) under conventional...

Pollen morphology of 15 species of the genus Lactuca L. (s. lat.) of the tribe Cichorieae from the Hindukush, Western Himalayan and Karakorum Ranges was studied using light microscopy and scanning electron microscopy. The pollen morphology of six speciesm viz. L. erostrata Bano & Qaiser, L....

A significant portion of crop production in the tropics occurs at subsistence level with high vulnerability to climate change. Process-based crop simulation models are effective tools to predict environmental impacts, including climate change effects, and make management decisions on crop...
