Abstract The response of root growth to various osmotic potentials is quite important in assessing the drought resistance rice. This study modeled seminal by applying consecutive polyethylene glycol (PEG) treatments (from 0 25%, 1% step), mathematical equations and noncontact image analysis quantitatively evaluate response. Treatment began after seeds were germinated, was recorded a digital camera every day from 7 20 days seeding (DAS). Although length (SRL) measured slightly varied with...

In order to identify the key factors that arrest yield improvement in rice, we observed fifteen divergent cultivars a field at Kyoto, Japan 1995 and 2001 under various nitrogen (N) regimes. The contribution sink size (spikelet number X single fully ripened grain mass), source (total available carbohydrate), components, non-structural carbohydrate (pre-reserved) full heading (NSCh) dry matter production during filling (DMP) had variation among was examined. weight of rough brown rice (Y)...

The research was conducted  in February-July 2010 in the greenhouse University Farm, Cikabayan, Dramaga, Bogor. This study aims to determine effect of irrigation frequency on growth and production five strains of  lowland rice, critical point soil water potential  for  drought tolerant screening.  This used a randomized block  design  which consists two factors and   three replications  for each combination treatments. results this indicate that plant height  at 8 12 weeks after planting...

Iron (Fe) toxicity is a major constraint in rice production that decreases yield due to high level of soluble Fe. The aims this experiement were study the effect particular Fe concentrations nutrient solution on growth, and determine concentration caused light, moderate, severe toxiciy symptom. experiment was conducted greenhouse, Bogor Agricultural University from May July 2010. A randomized block design with two factors three replications used study. first factor medium (2, 50, 100, 200,...
