The response of wheat crops to elevated CO2 (eCO2 ) was measured and modelled with the Australian Grains Free-Air CO2 Enrichment experiment, located at Horsham, Australia. Treatments included CO2 by water, N and temperature. The location represents a semi-arid environment with a seasonal VPD of around 0.5 kPa. Over 3 years, the observed mean biomass at anthesis and grain yield ranged from 4200 ...
lentil is considered as salinity sensitive species and is adversely affected in response to the salt stress in terms of growth and yield. this pot experiment was conducted to determine the effect of exogenous salicylic acid (sa) application on physiology, growth, yield and yield components of lentil grown under salt stress in greenhouse conditions, in a factorial arrangement based on randomized...
In the major wheat growing countries, wheat growth and yield are negatively affected by salinity and breed tolerant cultivars through selection and breeding techniques is necessary to solve this problem. Relationship among yield, and its related traits in 23 wheat cultivars and promised lines were studied under salt stress conditions using a randomized complete block design with three replicati...
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...
Improving the efficiency of resource utilization has received increasing research attention in recent years. In this study, we explored the potential physiological mechanisms underlying improved grain yield and water-use efficiency of winter wheat (Triticum aestivum L.) following organic fertilizer application. Two wheat cultivars, ChangHan58 (CH58) and XiNong9871 (XN9871), were grown under the...
Northeast China (NEC) is a region sensitive to climate change. However, the adoption of long-season maize cultivars in NEC has caused substantial yield increase under change conditions. It important determine whether such cultivar adoptions are effective throughout whole sustainably grain yield. In this study, phenological observations and meteorological data at six sites from 1981 2018 were us...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
drought stress is one of the important environmental factors reducing grain yield of plants in arid and semiarid regions. study the effect of water deficit stress on yield, water use efficiency and harvest index of sesame varieties, this experiment was conducted as a split plot based on a randomized complete block design with three replications, at agriculture and natural resources research cen...
the aim of this paper is eliminating cr(vi) by natural hap. hap is a inexpensive material which is used from bovine critical bone ash in order to remove heavy metal ions like cr(vi). some experiments in different ph are performed (ph=2,3,7). maximum adsorption was appeared at ph=2, dosage=0.3 gr, c0=10 mg/l. cr(vi) removal depends on ph value and initial amount of cr(vi) result of experiments w...
to determine the effects of different irrigation and salinity levels on qualitative and quantitative yield of sugar beet, an experiment was conducted for two years (2006-07)at torogh agricultural research center, mashhad, iran, using two sprinkler systems. each of the two irrigation systems was connected to two water sources with 1 and 6 ds/m salinity. irrigation was performed via two sprinkler...
