Evaluation of yields of seven upland rice (Oryzae sativa) cultivars sown by three methods in Anyigba, Kogi State, Nigeria
Sowing method establishment count plant height
2011/1/12
Yield is the characteristic by which a cultivar is commonly judge. A cultivar may be considered satisfactory only if it is able to produce a good yield in comparison to others at various times and in ...
Genetic Studies of Two QTLs for Rice Stripe Resistance Identified in Japanese Upland Rice Line, Kanto 72
near-isogenic lines quantitative trait loci rice breeding
2010/10/25
Quantitative trait locus (QTL) analysis was performed to identify the chromosomal region controlling rice stripe virus (RSV) resistance in Japanese upland rice, Kanto 72. As a result, two QTLs were de...
Genotypic Variation in Ability to Recover from Weed Competition at Early Vegetative Stage in Upland Rice
Improved cultivar Laos Recover from weed competition Slash-and-burn Traditional cultivar Upland rice
2010/3/4
In northern Laos, weeds are a major constraint to upland rice production in slash-and-burn systems. Two experiments were conducted to assess genotypic variation in ability to recover from weed competi...
Agronomic and socio-economic constraints to high yield of upland rice in Tanzania
NERICA adaptability soil fertility upland rice agro-ecosystems productivity
2011/1/10
A field survey was conducted in March 2009 in upland rice growing agro-ecosystem of four districts in Tanzania namely Ulanga, Kyela, Morogoro and Korogwe to investigate the agronomic and socio-economi...
Estimating crop coefficient model for upland rice (NERICA) under sprinkler irrigation system
Crop coefficient upland rice sprinkler irrigation
2011/1/10
Efficient crop coefficient (Kc) estimation is very important to adequately determine water use of a selected crop. In this study, crop coefficient was determined for upland rice (NERICA) under a sprin...

Yield Stability of Aromatic Upland Rice with High Yielding Ability in Indonesia
Adaptability Aromatic upland rice Yield stability
2009/7/21
Aromatic rice variety, Mentikwangi, was crossed with high-yielding upland rice variety, Poso, and the pedigree was selected to obtain lines with high yielding and aromatic characters. The objectives o...
Effect of Nontilled Cropping on Drought Injury of Upland Rice
Drought injury Nontilled cropping Upland rice
2009/7/15
The effect of non tillage on drought injury of upland rice was studied in Andosol upland fields. In 1988, 1990, and 1992, upland rice (cv. Toyohatamochi) was grown on nontilled and tillaged upland fi...
Chemical and Physical Properties of Carbonized Sewage Sludge Produced at Various Collection Sites, Seasons and Carbonizing Temperatures and Their Fertilizer Effect on Upland Rice Growth
Carbonized sewage sludge Dewatered sewage sludge Fertilizer effect Sewage sludge Total nitrogen
2009/7/14
Carbonized sewage sludge has more advantages in terms of storage and transportation than dewatered sewage sludge, but no detailed studies have so far been conducted on the former. Dewatered sewage slu...
Differences in the Morphophysiological Response to Atmospheric Humidity between Paddy and Upland Rice
Stomatal density Transpiration Paddy rice Atmospheric humidity
2009/7/9
The effects of atmospheric humidity on vegetative growth of paddy and upland rice were compared. A low atmospheric humidity (60%RH) significantly decreased the dry-matter production in paddy rice but...
