The present study aimed at investigating the effect of different levels of nitrogen on yield and yield components of bread and durum wheat. To this end the experiment was conducted in 2010-2011 in south west of Iran as split plots based on randomized complete block design with three replications. Main plot included four levels of nitrogen 60, 120, 180, 240 kg.ha-1 and the sub plot included four...
Mechanized forest harvest operations induce changes in soil physical properties, which have the potefitial to impzct soil sustai~ability and forest productivity. The assessment of soil compaction and its spatial variability has been determined previously through the identification and tabulation of visual soil disturbance classes and soil physical changes associated with each disturbailce class...
Genetic variation of 300 genotypes of durum wheat comprising CIMMYT/ICARDA and Iranian germplasm was evaluated in 1999-2000 at Researh Farm of College of Agriculture, Isfahan University of Technology located at Lavark, NaJaf-Abad. Days to heading, days to maturity, plant height, spike length, grain weight per spike, number of grain per spike, number of spikes per m2, 1000-grain weight, test wei...
saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
the aim of this experiment was the study of dry matter and nitrogen (n) accumulation, remobilization and harvest index in different wheat cultivars. five bread wheat cultivars (darya, kuhdasht, shiroudi, tajan and zagros) and two durum wheat cultivars (arya and dena) were studied under optimum growth conditions during 2008-2009 at research field of gorgan university of agricultural sciences and...
Abstract: This research was conducted to investigate the effect of sowing date on growth and yield of five rapeseed (Brassica napus L.) cultivars. The experimental design consisted of four randomized complete blocks (CRDB) in a split-plot arrangement. Four convetional sowing dates (11 September, 27 September, 12 October and 27 October) as main plots and five rapeseed cultivars (RGS00...
This experiment was conducted at Debre Zeit and Akaki during 2004-2005 cropping season on F2-derived F4 bulk families of three crosses, viz, DZ-01-974 x DZ-01-2786, DZ-01-974 x DZ-Cr-37 and Alba x Kaye Murri. To estimate the correlations and path coefficients between yield and yield components, 63 F4 families were taken randomly from each of the three crosses. The 189 F4 families, five parents ...
in order to investigate the effects of cattle manure, benefit fungi of trichoderma species and psudomunas spp. bacteria on seedling emergence parameters, growth and yield of wheat (triticum aestivum l.) a pot experiment was carried out in factorial (23) arrangement based on a randomized complete design with three replications. the treatments were three levels of cattle manure (10, 20 and 30 t.h...
effects of morph physiological characteristics on yield and yield components of corn grain were investigated. an experiment was conducted in the experimental field of abourayhan campus, university of tehran. the experimental design was a block in split plot arrangement with four replications. planting dates were as main factor with three levels (4th, 14th and 25th june) and four varieties (sing...
