To evaluate the effect of nitrogen fertilizer amounts on grain yield of forage corn in 2012, a pilot was implemented in Islamic Azad University Agricultural Research Station, Isfahan, as a split plot in a randomized complete block design. Main plots consisted of four levels: control (no fertilization ) , 50 , 100 and 150 kg per ha nitrogen from urea source and subplots , including several varie...

in order to estimate heritability and gene action for grain yield and its related traits in lentil, six basic generations were evaluated in a randomized complete block design with three replications in a field experiment. besides seed yield per plant, plant height, pod length, and 100-seed weight, the number of pods per plant, primary branches, clusters per plant, nodes per main stem, secondary...

Thirty-seven genotypes of coriander including six check varieties were analyzed for variability, correlation, path coefficients, and genetic divergence. Genotypes grown in RBD with three replications observations recorded 13 different quantitative traits. Secondary branches per plant total oil content confirmed high values GCV PCV. Seeds umbel, test weight, exhibited heritability along GA (% me...

common vetch ) vicia sativa .l) is belong to fabaceae family and due to adaptation and tolerance to environmental stresses are considered. in this research, morphological and agronomic characteristics of 89 genotypes of common vetch ) vicia sativa .l) were evaluated in an augmented design under irrigated and drought stress conditions in research field of university of tehran at karaj in 2011. r...

considering the importance of medicinal plants growth and biological application of fertilizers with sustainable agricultural production in order to eliminate or reduce chemical input to achieve desirable and sustainable quality, an experimental research was  conducted based on a randomized complete block design with two factors of chemical nitrogen (46% urea nitrogen) at  two levels (zero, 25 ...

in order to study the effects of different levels of animal manure and bulb weights on growth criteria, yield components, seed yield and essential oil yield of caraway, an experiment was conducted as factorial based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of mashhad, during two growing seasons of 2012-2013 and 2013-...

soil salinity is a serious problem in south khouzestan province. this study was conducted in shawoor agricultural research station, north of the city of ahwaz, on silty-clay soil with 8 dsm-1 salinity during 2006 and 2007. a completely randomized block design arranged in split plots with three replications was used. the plots (planting methods) were: broadcasting + disk harrow (p1), broadcastin...
