Investigating the relationship between NDVI and LAI in semi-arid grassland in Inner Mongolia using in-situ measurements
SummaryLeaf area index (LAI) is a key variable functionally related to plant biomass production. Accurate estimation of LAI is important for monitoring vegetation dynamics, and LAI information isExpand
Effects of supplied nitrogen form on growth and water uptake of French bean (Phaseolus vulgaris L.) plants
In order to investigate the effect of N form on dry matter (DM) formation and water uptake rate, French bean (Phaseolus vulgaris L. `Sotaxa') plants were grown with a split-root system. ThreeExpand
Interaction between root growth and mineral nutrition
Abstract The close interrelationships between root growth and mineral nutrient supply on the one hand, and root parameters and genotypic differences in mineral nutrient efficiency on the other, areExpand
Varietal differences in shoot and rooting parameters of pearl millet on sandy soils in Niger
Root parameters are important traits for the acquisition of nutrients and water under resource-limited conditions. In order to investigate the extent of varietal differences in rooting parameters inExpand
Spatial distribution of roots of pearl millet on sandy soils of Niger
Root sampling in crop stands of low planting density requires reliable information on horizontal distribution of roots. This applies particularly to pearl millet in the Sahel, which is sown at a rateExpand
Response of Lowland and Aerobic Rice to Ammonium and Nitrate Supply During Early Growth Stages
ABSTRACT Decreasing fresh water availability has intensified the search for alternative rice cultivation systems with reduced water input, but most evidence suggests negative effects on growth ofExpand
Yield stability and genotype x environment interactions of upland rice in altitudinal gradient in Madagascar
The growing demand for rice and the increasing pressure on irrigated land in Madagascar is strengthening efforts to developing upland rice systems. Actual yield is below its potential yield inExpand
Influence of N form on growth photosynthesis of Phaseolus vulgaris L. plants
Many plant species are characterized by pronounced sensitivity to sole ammonium supply and exhibit growth depression and particularly reduced leaf growth rates. Stress symptoms under sole ammoniumExpand
Effects of Water and Nitrogen Supply on Water Use Efficiency and Carbon Isotope Discrimination in Edible Canna (Canna edulis Ker‐Gawler)
: Transpirational water use efficiency (WUE) is affected by nutrient and water supply, but relatively little is known about the response of Andean root and tuber crops, such as edible canna (CannaExpand
The effect of low nitrogen supply on yield and water-use efficiency of sweet potato (Ipomoea batatas L.).
A pot experiment was conducted in a tropical mid-elevation environment to evaluate sweet potato clones of different origin and breeding intensity for traits related to growth phenomena, nitrogen useExpand
