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...

Twenty hybrids were produced using five CMS lines viz., BRRI3A, BRRI9A, IR73328A, BRRI10A and IR78355A and four restorers viz., BRRI12R, BRRI13R, BRRI14R and BRRI15R following line x tester mating design to find out the best combination (s) in respect of their combining ability effects among the parents and hybrids at BRRI, Gazipur, Bangladesh from July 2008 to May 2009. Data were recorded from...

Rice (Oryza sativa) is one of the most important food crops in the world. Numerous quantitative trait loci or genes controlling panicle architecture have been identified to increase grain yield. Yet grain yield, defined as the product of the number of well-ripened grains and their weight, is a complex trait that is determined by multiple factors such as source, sink and translocation capacity. ...

seed production, as well as other economical and ecological attributes, is an important character in grasses. knowledge on the genetic diversity of seed yield and yield components on iranian tall fescue accessions, as a high productive and adaptive grass is limited. this experiment was conducted to investigate the genetic diversity of seed yield and seed components, determine relationships betw...

this study was aimed at evaluating the effects of planting’s different dates on the trend of leaf area index, dry biomass weight and panicle weight in addition to the yield of rice varieties for one year in the north region of khuzestan, as spilt plots in the form of fully random blocks in three repetitions. main factor was the date of planting at three levels (26 may, 10 jun, 26 jun) and the s...

Inbred rice has been grown more and widely, while the planting area of hybrid decreased by approximately 25% in China since 1995. This study aimed to assess changes grain yield attributes due cultivar development indica (Oryza sativa ssp. indica) inbred China. Field experiments were conducted 2019 2020 determine performance an super Jinnongsimiao (JNSM) released 2010 comparing it with high-yiel...
