The vegetation green-up date (GUD) of the Tibetan Plateau (TP) is highly sensitive to climate change. Accurate estimation GUD essential for understanding dynamics and stability terrestrial ecosystems their interactions with climate. usually determined from a time-series indices (VIs). adoption different VIs extraction methods can lead GUDs. However, our knowledge uncertainty in these GUDs on TP...

Identifying regional variations and agronomical records can turn into a function of magnitude timing for sustainable maize production. The crop characteristics are directly related with the temperature precipitation from growing season. Therefore, main aim this study was to highlight requirements most suggestive Romania. A literature search performed based on keywords both agrometeorological re...

In agrometeorology and management of meteorology related natural resources, many traditional methods and indigenous technologies are still in use or being revived for managing low external inputs sustainable agriculture (LEISA) under conditions of climate variability. This paper starts with the introduction of an “end-to-end” climate information build up and transfer system in agrometeorology, ...

The disease brown spot of pear (Pyrus communis L.) (BSP) is caused by the fungus Stemphylium vesicarium (Wallr.) E. Simmons. The economical losses caused by BSP are very important in several pear production areas of Europe including Spain, Italy, France, Portugal, The Netherlands and Belgium (Llorente and Montesinos, 2006). Control of BSP is based on fungicide applications during the growing se...

the zagreb indices are the oldest graph invariants used in mathematical chemistry to predictthe chemical phenomena. in this paper we define the multiple versions of zagreb indicesbased on degrees of vertices in a given graph and then we compute the first and secondextremal graphs for them.
