Barnyardgrass control in conventional and Clearfield rice grown under intermittent flooding

Intermittent Irrigation Effects on Barnyardgrass Weed Control and Rice Yield

Use of Clearfield Rice Technology in Stale and Conventional Seedbed Systems and Clomazone in a Stale Seedbed System

Experiments were conducted during the summer of 2002 at the Rice Research and Extension Center, Stuttgart, AR, to evaluate: 1) various timings of sequential applications of imazethapyr at 0.063 lb/acre (4 oz Newpath/acre) in conventional and staleseedbed rice planting systems utilizing Clearfield ‘CL-161’ and 2) the timing of clomazone application at various rates and timings in conventional ri...

Rice Bran Application under Deep Flooding Can Control Weed and Increase Grain Yield in Organic Rice Culture

Rice bran application just after transplanting has been increasingly practiced as a herbicide-substitute for organic rice production in Korea. However, this practice is frequently reported to be unsatisfactory in weed suppression. An experiment with five treatments that combine flooding depth (shallow and deep), rice bran application level (low and high), and herbicide application was carried o...

Locating Genes Controlling Allelopathic Effects against Barnyardgrass in Upland Rice

the environment” (Rice, 1984). Rice plants with an allelopathic effect on weeds can mean lower production To understand the genetic control of allelopathy in rice (Oryza costs because the need for herbicide application and/or sativa L.), quantitative trait loci (QTL) mapping was performed using a population of 142 recombinant inbred lines derived from a cross hand weeding is reduced. Thus, inco...

Identification of Informative Alleles Controlling Rice Traits under Flooding and Drought Stress Conditions‌‌

One of the main objectives of plant breeding is defining the relationship between genotype and phenotype. Nowadays, molecular markers provide powerful tools to evaluate this relationship for plant breeders. In this study, genetic diversity of 112 rice lines was evaluated by 20 pairs of SSR markers which linked to drought tolerant alleles. Totally, 77 polymorphic alleles with mean of 3.85 allele...
