Biomass yield of rice (Oryza sativa L.) is an important breeding target, yet it is not easy to improve because the trait is complex and phenotyping is laborious. Using progeny derived from a cross between two high-yielding Japanese cultivars, we evaluated whether quantitative trait locus (QTL)-based selection can improve biomass yield. As a measure of biomass yield, we used plant weight (aboveg...
In order to study the effects of different irrigation regimes and plant density on yieldcomponent and protein concentration and crop water stress index (CWSI), under research fieldconditions a split plot arrangement was conducted in completely randomized block designduring two years. The first factor of variables was the effects of 4 irrigation levels 120% (I1),100% (I2), 80% (I3) and 60% (I4) ...
to investigate the effect of supplemental irrigation and nitrogen fertilizer on kernel weight, test weight and wheat grain yield under dryland conditions, a two-year field experiment was conducted in the research farm of college of agriculture, shiraz university during 2004-2005. five irrigation regime including dryland conditions, irrigation at stem elongation, booting, flowering and grain fil...
In order to evaluate biofertilizer, nitrogen and humic acid effect on quantitative and qualitative traits of chickpea (ILC 482 line) this research was carried out at the Agricultural Research Field of Kurdistan University, Sannadaj, Iran. A factorial experiment was conducted based on a randomized complete block design with three replications. Experimental treatments included three levels of lea...
An experiment was conducted to evaluate the effects of organic acids and phytase enzyme supplementation on immune system and carcass characteristics of broiler chickens. The experiment was done in factorial arrangement 2×2×2 based on completely randomized design with 8 treatments, 5 replicates and 12 chicks in each to 42 d of age. Diets including natural vinegar (0 and 2%), citric acid (0 and 1...
Increased whole grain intake has been shown to reduce the risk of many non-communicable diseases. Countries including the USA, Canada, Denmark and Australia have specific dietary guidelines on whole grain intake but others, including the UK, do not. Data from 1986/87 and 2000/01 have shown that whole grain intake is low and declining in British adults. The aim of the present study was to descri...
Fourteen sesame lines that have preferred in primary evaluation, with local mass of Birjand (as test) and Ooltan cultivar (as overall test) were compared for two years in completely block design with 4 replication. Traits measured in this study were germination percent, number of flower per axis, number of sub branch, capsule length, plant height, number of capsules per plant, height of first c...
source limitation during grain filling is important for both management and breeding strategies of grain crops. there is little information on the sensitivity of grain yield to various source-sink ratios in various wheat (triticum aestivum) cultivars. the objective of the current study was to evaluate the response of grain yield as well as yield components to different source-sink ratios during...
degraded soils in northwest china are mostly nonproductive due to imbalanced nutrient and inadequate water supply. the effects of manure application at three different rates (7.5, 15.0, and 22.5 t ha–1) combined with chemical fertilizers on soil water and water-use efficiency in maize [compared with chemical fertilizers (control)], under semi-arid conditions in dark loessial soil and over a per...
Salt stress is one of the major factors limiting crop productivity worldwide. Grain amaranth is new crop with high yield potential and good nutrition value which can be a good substitute for salt-sensitive crops in saline areas. This research was conducted to evaluate different level of salinity and applied salinity stress at several growth stages on some morphological and physiological traits ...
