One of the major issues of increasing agricultural production, is adaptation of technology to specific climatic variables in cultivated areas. Knowing the weather and climatic condition and periodic yearly and multi-year changes of meteorological phenomena and deviations from normal values ​​are of major requirements of modern agriculture. In this study, daily, monthly and annual weather data o...

persian shallot is one of the important medicinal and industrial plants in iran which is under very dense utilization. study of morphological characteristics in this plant in agronomical systems is very important for expanding agronomic production of this plant. in order to evaluate some physiological, yield characteristics and thermal requirement of two species of shallot, a field experiment w...

Carnation crop in Colombia is one of the main income generating activities Colombian floriculture. However, growth dynamics and its relationship with thermal time are unknown. For this reason, objective research was to determine development carnation (Dianthus caryophyllus L.) cv. ‘Moon Light’ when grown a greenhouse Bogotá savanna. This developed based on phenological stages accumulation Growi...

The distribution of hookworm in schistosomiasis-endemic areas in Brazil was mapped based on climate suitability. Known biological requirements of hookworm were fitted to data in a monthly long-term normal climate grid (18 x 18 km) using geographical information systems. Hookworm risk models were produced using the growing degree day (GDD) water budget (WB) concept. A moisture-adjusted model (MA...

Climate-induced crop yields model projections are constrained by the accuracy of the phenology simulation in crop models. Here, we use phenology observations from 775 trials with 19 rice cultivars in 5 Asian countries to compare the performance of four rice phenology models (growing-degree-day (GDD), exponential, beta and bilinear models) when applied to warmer climates. For a given cultivar, t...
