Abstract The El Cañizar de Villarquemado pollen record covers the last part of MIS 6 to Late Holocene. We use Tolerance-Weighted Averaging Partial Least Squares (TWA-PLS) reconstruct mean temperature coldest month (MTCO) and growing degree days above 0°C (GDD 0 ) ratio annual precipitation potential evapotranspiration (MI), accounting for ecophysiological effect changing CO 2 on water-use effic...

Leaf Area of Index (LAI) refers to half the total leaf area all crops per unit area. It is an important index represent photosynthetic capacity and biomass crops. To obtain LAI conditions summer maize in different growth stages quickly accurately, further guiding field fertilization irrigation. The Unmanned aerial vehicles (UAV) multispectral data, growing degree days, canopy height model 2020-...

The soil and climate conditions in Romanian Northeastern area are favorable for cherry cultivation, but some times can occurred calamities. paper presents a study which during 2020 at the Research Station Fruit Growing (N-E of Romania), using five sweet genotypes as research material: ‘Van’, ‘Croma’, ‘Elaiași’, ‘HC920402’, ‘HC930208’. Observations determinations were performed regards to frostd...

in order to study the phonological stages and growth period of invasive weed ranunculus ficaria based on degree days and to study the effect of planting depth on sprouting the tubers roots of this weed, two separate experiments were conducted in crd with 5 replications at ferdwosi university of mashhad in 2008. in the first study germinated tubers were planted in 5 cm depth and the observations...

Climate is one of the most important factors that influence the quality and quantity of crops. Understanding the natural features of any region, especially about the climate, can play a major role in making plans and land use planning. Sugar beet, is one of the major industrial plants, that in addition to producing one of the most fundamental basic needs of society, namely sugar, it can have ot...
