Nitrogen Uptake by Cover Crops and Inorganic Nitrogen Dynamics in Andisol Paddy Rice Field
Cover crop Paddy field Nitrogen
2010/12/2
Paddy field rice can conserve N in the soil under flooded conditions. However, residual soil N represents a potential environment concern when fields are no longer flooded. Winter annual grass cover c...
Growth Response of Rice (Oryza sativa L.) to Drought:I. Varietal difference in growth rate, nitrogen uptake and tillering habit at vegetative stage
Drought resistance Growth analysis Nitrogen uptake Plant type Rice Tillering habit
2009/8/6
Varietal differences in growth response to drought were studied in order to determine major attributes composing drought resistance in the rice plant. Eight rice varieties of different hydrological b...
Effect of Slow Release Fertilizer(Meister)on the Nitrogen Uptake and Yield of the Rice Plant in the Tropics
Growth N-uptale Rice plant Slow release fertilizer
2009/8/5
Field experiments on the response of rice plants to slow release fertilizer (Meister 10, MS10) were conducted from the 1986 wet season (WS) to the 1987 WS at IRRI, with ammonium sulfate (AS) as contr...
Patterns of Soil Nitrogen Release in Paddy Fields of Warm Regions in Japan and Diagnosis of Fertilizer Application : II. Characteristics of soil nitrogen mineralization and nitrogen uptake patterns of rice plants in Fukuoka Prefecture
Amount of nitrogen uptake Fertilizer nitrogen Nitrogen mineralization Paddy soils Soil nitrogen
2009/8/4
Topsoils collected from various regions in Fukuoka Prefecture were incubated and the amount of mineralized nitrogen was measured. The relationship between the mineralized nitrogen amount (N) and the ...
Nitrogen Uptake by Faba Bean from 15N-Labelled Oilseed-Rape Residue and Chicken Manure with Ryegrass as a Reference Crop
Chicken manure Faba bean N uptake Nutrition Oilseed-rape residue Ryegrass
2009/7/29
The effects of soil amendment with oilseed-rape residue (OSRR) and chicken manure (CM) on the growth and nitrogen (N) uptake of faba bean (Vicia faba L.) were assessed in a pot experiments with Italia...
Interspecific Differences in Growth and Nitrogen Uptake among Crotalaria species
C-N ratio Crotalaria Dry matter production Green manure crop Nitrogen fixation Nitrogen uptake
2009/7/28
The interspecific differences in germination, root nodule formation, dry matter production and nitrogen uptake were evaluated among Crotalaria species for the introduction as new green manure legumes....
Spatial Distribution of Leaf Area Index and Leaf N Content in Relation to Grain Yield and Nitrogen Uptake in Rice
Grain yield Leaf area index Leaf N content N uptake Spatial distribution
2009/7/23
Exploring approaches to optimizing spatial distributions of leaf area index (LAI) and leaf nitrogen content (LNC) should be useful for increasing grain yield in rice (Oryza sativa). The primary object...
Continuous Monitoring of Visible and Near-Infrared Band Reflectance from a Rice Paddy for Determining Nitrogen Uptake Using Digital Cameras
Digital camera Near-infrared Nitrogen absorption Red Reflectance Rice SPAD
2009/7/21
A two-band digital imaging system —one band for the visible red band (RED, 630−670 nm) and the other for the near infrared band (NIR, 820−900 nm)— was devised and positioned at a height of...
