in order to study the effect of irrigation cut on dry matter remobilization and some of agronomy traits on spring barley, a field experiment was conducted by using a split-plot based on randomized complete block design (rcbd), in three replications, at agricultural and natural resource research center of ardebil, in 2009. irrigation treatments included normal irrigation (as local routine in pas...

To help farmers in the mid hills of Nepal improve their crop management and rice yields, we conducted a study testing different nursery management options and their effect on grain yield and yield components under rainfed conditions. The experiment was conducted in a farmer’s field during the cropping season 2009 and 2010 at Sundarbazar, Lamjung, Nepal, using a 3-factor factorial RCB design wit...

Grain yield of the rice can be enhanced through genetic manipulation of the yield components. Thousand grain weight is an important component which can be improved through conventional as well as molecular breeding approach. A major effect novel genomic region, TGW10, for high grain weight was identified through a bulked segregant analysis approach in Azucena × IR64 population. Markers associat...

The appearance and cooking quality of rice determine its acceptability and price to a large extent. Quantitative trait loci (QTLs) for 12 grain quality traits were mapped in 2 mapping populations derived from Oryza sativa cv Swarna × O. nivara. The BC(2)F(2) population of the cross Swarna × O. nivara IRGC81848 (population 1) was evaluated during 2005 and that from Swarna × O. nivara IRGC81832 (...

in order to study the effect of mallow weed competition and nitrogen (n) rates on grain yield and yield components of wheat cv. chamran, a field experiment was conducted in 2009. the experiment was designed as a split-plot with three replications and additive series. the n application rates were assigned in the main-plots (50, 100, 150 and 200 kg.n.ha-1) and sub-plots consisted of target common...

the erosion in dryland caused decrease in yield and soil quality, especially in slope land with conventional tillage. to investigate effect of tillage and planting methods in slope land on erosion and yield of dryland wheat, an experiment was conducted in 2007 at kermanshah province. the statistical design for this research was strip split plots in rcb (randomized complete blocks) with three re...
