This study compares nematode prevalence in upland rice fields, which differed in cropping intensity, in Ùlree agroecological zones of Ivory Coast. Eighty nematode species from 35 genera were found associated with rice. Population densities of Helicorylenchus spp. were significantly lower in long fallows in the forest zone, but the mean population densities of ail other nematode genera and speci...

China is the first country to use heterosis successfully for commercial rice production. This study compared the main quality characteristics (head rice rate, chalky rice rate, chalkiness degree, gel consistency, amylose content, and length-to-width ratio) of 635 rice varieties (not including upland and glutinous rice) released from 2000 to 2014 to establish the quality status and offer suggest...

Switchgrass (Panicum virgatum L.) exists at multiple ploidies and two phenotypically distinct ecotypes. To facilitate interploidal comparisons and to understand the extent of sequence variation within existing breeding pools, two complete switchgrass chloroplast genomes were sequenced from individuals representative of the upland and lowland ecotypes. The results demonstrated a very high degree...

Seedlings of three rice (Oryza sativa L.) varieties (one indica, ARC5955; and two japonica, Nipponbare and Koshihikari) with or without pre-colonization by the arbuscular mycorrhizal fungus Funneliformis mosseae were transplanted into an upland field and grown to maturity. Pre-colonization had no effect on the yield of Nipponbare or Koshihikari. However, pre-colonized ARC5955 exhibited a strong...

Here we examined the properties of endosperm starches and the physical properties of cooked rice from four cultivars of Japanese upland rice containing M-type amylopectin (Chikanarijyun1, Kairyo13, Mogamichikanari1 and Hokkaiakage); S-type Nipponbare and L-type Kasalath served as standards. The amylopectin chain ratio (ACR ; ratio of the short chains of DP ≤ 10 to the short and intermediate cha...

Nitrogen (N) fertilizers are a major input cost in rice production, and its excess application leads to major environmental pollution. Development of rice varieties with improved nitrogen use efficiency (NUE) is essential for sustainable agriculture. Here, we report the results of field evaluations of marker-free transgenic NERICA4 (New Rice for Africa 4) rice lines overexpressing barley alanin...

Abstract Upland rice is a food crop commodity that can be cultivated on dry land. Increasing soil fertility land through the addition of organic materials in form biochar and fertilizers. The aim this research was to examine growth upland application several types conducted Sukosari Jumantono Village, Karanganyar March-June 2022. used completely randomized block design. first factor type (witho...

Abstract: Ridge culture is a special conservation tillage method, but the long-term influence of this tillage system on soil aggregate-size stability in paddy fields is largely unknown in southwest of china. The objectives of this paper are to evaluate soil aggregates stability and to determine the relationship between SOC and soil aggregate stability.Soil samples at 0-20 cm layer were adopted ...

Rice is the staple food of almost half of the world population, and in excess 90% of it is grown and consumed in Asia, but the disposal of rice straw poses a problem for farmers, who often burn it in the fields, causing health and environmental problems. However, with increased focus on the development of sustainable biofuel production, rice straw has been recognized as a potential feedstock fo...
