in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
karim as a new line (hamam-4: t.aest/sprw's'//ca8055/3/bacanora86 icw92-0477-1ap-1ap-4ap-1ap-0ap) was evaluated at gachsaran agricultural research station in 2004-2005. it was selected for its high grain yield (3975 kg ha-1) and included in advance yield trial in gachsaran, khoramabad, gonbad, moghan and ilam field stations in next growing season. average yield of this line and check ...
TThe existence of genotype– environment interaction requires that the performance of genotypes be tested in a wide range of environmental conditions so that the resulting information can increase the efficiency of their selection and introduction. For this purpose, this study using 11 selected lines from uniform national experiments, along with control figures of Saral and Anna and two advanced...
Public agricultural research in the United States is conducted by state agricultural experiment stations (SAES) and by the research agencies of the USDA. Both have research activities in every state. A vast amount of research and experiments has shown that the performance of plants and to a lesser extent animals, in which new technologies are frequently embodied, is altered by local geoclimatic...
abstract the cr(iii) and zn(ii) complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl)benzoic acid as ligand have been prepared by reacting cr(no3) and zn(no3)2 and ligand in cloroform. the cr and zn complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl) were also prepared in chloroform and aceton solutions. the uv-visible and ft-ir spectra of...
drought stress as the most important abiotic stress plays a significant role in reduction of crops yield. this study was conducted at six agricultural experimental stations (karadj, ardebil, arak, mashhad, jolgerokh and miandoab) during 2006-08 cropping seasons. experiments were carried out under normal irrigation and post-anthesis drought stress conditions using 18 wheat genotypes. experimenta...
Agricultural sector is most dependent on climate, and climate is the main determinant of time, location, production resources, and productivity of agricultural activities. The first event of zero-degree temperature in fall and its last event in spring is important for agriculture. This information is used to determine the species suitable for planting in each area. The present study seeks to id...
Weather and climate parameters and their effects on crops, is one of the most effective factors in yield increase. Agro-climatic studies could be used to determine the potential of various regions and the exploit these resources to the maximum possible extent. In this study, in order to evaluate the agricultural climate of spring canola cultivation in selected stations in Hamedan province, the ...
in sustainable agriculture, using of resistant plants is one of the best methods for integrated pest management. resistance of 140 rice promising lines against striped stem borer was evaluated in two planting date in the field under natural infections in sari agricultural science and natural resources university during 2008-2009. this study carried out as a factorial experiment in randomized co...
