Japanese sake-brewing rice cultivars show high levels of globulin-like protein and a chloroplast stromal HSP70
White-core is an important trait in the selection of rice (Oryza sativa L. ssp. japonica) for sake (Japanese rice wine) production. The present study was conducted to find differences between the endosperm protein pattern of white-core–bearing sake-brewing cultivars and those of normal rice grains. Protein patterns of white-core sake-brewing grains were compared with those of normal cultivars by ...

Genotype x environment interactions of hybrid and varietal rice cultivars for grain yield and milling quality
The study of genotype x environment interaction is critical for accurate cultivar evaluation in large multi-environment trials. Cultivars that exhibit high levels of mean performance and stability across a wide range of environmental conditions are desirable for rice production. Pure-line varietal and hybrid rice cultivars are commercially produced in the U.S.; however, little research has been ...

Characterization and greenhouse evaluation of brazilian calcined nonapatite phosphate rocks for rice
Little information is available on the agronomic effectiveness of calcined nonapatite phosphate rock (PR) sources containing crandallite minerals in the form of Ca–Fe–Al–P for flooded and upland rice (Oryza sativa L.). We conducted laboratory and greenhouse studies to (i) characterize the mineralogical composition, (ii) investigate the solubility and dissolution behavior, and (iii) evaluate the ...

Dissipation and residues of trifloxystrobin and its metabolite in rice under field conditions
Residue analysis of trifloxystrobin and its metabolite (CGA 321113) in rice matrices, paddy water, and soil was developed using the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method and high performance liquid chromatography tandem mass spectrometry (HPLC‐MS/MS). The method was used to evaluate the dissipation rate of trifloxystrobin and CGA 321113 in rice seedling, soil, and ...

Stability of rice grain and whole kernel milling yield is affected by cultivar and date of planting
The objectives of this study were to evaluate rice (Oryza sativa L.) cultivar stability and to characterize different planting dates for their consistency in grain yield and milling. Eight rice cultivars and seven planting dates were evaluated from 2003 to 2005 for a total of 19 yr x planting date environments. The coefficient of variation of cultivars and planting dates, a measure of relative ...

Response of upland rice cultivars to nitrogen fertilizer in the savannas of Nigeria
In the dry savannas of West Africa, cultivation of upland rice (Oryza spp.) under rain-fed conditions is expanding due to the introduction of the New Rice for Africa (NERICA; WARDA, Bouake, Cote d'Ivoire) but appropriate N recommendations for these new cultivars are lacking. The present study evaluated the response of four NERICA rice cultivars, their parents (WAB 56-104 (O. sativa, tropical ...

Correlation and calibration of soil potassium availability with rice yield and nutritional status
Soil testing is an important tool for estimating soil K availability and determining how much fertilizer must be applied to realize crop yield potential and minimize fertilizer costs. Our primary objectives were to correlate relative rice (Oryza sativa L.) yield with Mehlich-3 and 1 mol L–1 HNO3 extractable K, define sufficient whole-plant K concentrations at panicle differentiation (PD) and ...

Triangular transplanting pattern and split nitrogen fertilizer application increase rice yield and nitrogen fertilizer recovery
Field experiments were conducted to evaluate the effects of improved crop management (OPT) for irrigated rice (Oryza sativa L.) on grain yield and N recovery efficiency in southwestern China. In the OPT treatment, rice seedlings were transplanted in a triangular spatial pattern and the N fertilizer was split, based on the difference between the estimated total N requirement and the soil and ...

Mapping of quantitative trait loci using a doubled-haploid population from the cross of indica and japonica cultivars of rice
Improving the cooking and eating quality of grain has always been an important consideration in most rice (Oryza sativa L.) breeding programs. In this study, an established rice doubled-haploid (DH) population consisting of 219 lines from anther culture of the F1 of indica variety PSB Rc10 and japonica variety Nipponbare was used to identify the quantitative trait loci (QTL) for amylose content ...

Forty-eight years of rice improvement in Texas since the release of cultivar bluebonnet in 1944
Information on the contribution of plant breeding to changes in yields and other agronomic traits is useful for optimizing selection gains; thus, this study aimed to determine the contribution of Texas rice (Oryza sativa L.) breeding to changes in cultivars released during the 48 yr since the release of ‘Bluebonnet’ in 1944. Twenty-three cultivars were evaluated in three environments and two N ...

Efficiency in Food Plant Increases with Thern
Torn and Glasser, founded in 1928, has been a family-owned business for over 85 years, passed down three generations. The business began growing walnuts and watermelons, marketing their fresh produce in Los Angeles, California. They have since expanded their wholesale produce line and now import, process and package nuts, dried fruit, beans, rice, spices, candies and grains. Like Thern, Torn and ...

Rice growth, grain yield, and floodwater nutrient dynamics as affected by nutrient placement method and rate
The loss of major nutrients can be high in rice (Oryza sativa L.) fields, particularly rainfed rice, where water flowing from field to field during periods of high rainfall not only reduces the nutrient use efficiencies but also has the potential for environmental degradation. We examined the influence of deep point placement of N, P, and K briquettes compared to broadcast incorporation of N, P, ...

Rice seeding and nitrogen rate effects on yield and yield components of two rice cultivars
Field research was conducted for 2 yr to investigate the relationship between rice (Oryza sativa L.) seeding rate and preflood nitrogen (N) rate utilizing long-grain rice cultivars planted into clay and silt loam soils. Rice cultivars included ‘Cheniere’ and ‘Wells’ seeded at 162, 323, and 646 seeds m–2. Nitrogen was applied before flooding at 67, 134, and 202 kg ha–1. No response to soil texture ...

Increase Productivity Manifold With An Efficient Rice Sorter Machine
If you run a rice mill, make rice paste from rice or selling rice as a retail shop, the first thing that you have to ensure is the quality of rice. High quality rice will be instantly bought by customers and it is nutritious and healthy to eat. In order to get this quality, the rice must be clean. It must not have any dust or dirt. It must also not have any yellow grains or immature grains in ...
