the aim of this study was to assess the effects of nucleotide on intestinal microbiota of striped catfish, pangasianodon hypophthalmus . different levels of the nt (0, 0.25. 0.5, 0.75 and 1 % weight per weight, ww -1 ) were added to basal diet and then randomly allocated to triplicate groups of fish with average initial weight (1.52±0.11 g) for 10 weeks. at the end of the experiment, at least 1...
To study the response of Hashemi (local) and Gilaneh (improved) rice cultivars to the application of different sources and levels of organic fertilizers, a field experiment was conducted using a randomized complete block design with three replications in 2018-2019 and 2019-2020 cropping seasons in research field of Rice Research Institute of Iran (Rasht), Iran. Experimental treatments include p...
Grain yield in wheat (Triticum aestivum L. emend. Thell.) is highly dependent upon the number of spike-hearing tillers produced by each plant. Soil salinity can greatly decrease their number and productivity. Knowing the contribution of specific tillers is essential for breeding salt-tolerant genotypes and for developing wheat growth simulation models. Our objective was to determine the effects...
The International Crops Research Institute for the Semi-Arid Tropics conserves 335 accessions of Pennisetum glaucum subsp. monodii originated in 13 countries. In the present study, the collection was evaluated and assessed for diversity and geographical gaps. A wide variation was observed in the collection for total tillers per plant (16 to 609), productive tillers per plant (12 to 368), leaf l...
selection tolerant cultivars of wheat (as a strategic plant) under drought stress by using traits that are less affected by the environment, increases efficiencies. In this regard, in order to study some genetic parameters of physiological and agronomical traits and also genetic diversity in spring wheat cultivars under normal irrigation (control) and drought stress conditions in booting stage,...
In order to study the effect of drought stress and determination of effective traits on grain yield of wheat in normal and terminal drought stress conditions, 82 wheat genotypes were studied in two separate experiments using randomized complete block design with three replications during cropping season 2011-2012. Drought stress was applied in heading stage by limited irrigation. Set of 22...
relationship between grain yield and its component traits can improve the efficiency of breeding programs by determining appropriate selection criteria. an investigation was carried out on barnyard millet (echinochloa spp.) global germplasm collection to investigate the association among yield components and their direct and indirect effects on the grain yield of barnyard millet. the experiment...
The purpose of this study was to analyze the population density and intensity attack Brown Planthopper (Nilaparvata lugens Stall) green leafhoppers (Nephotettix virescens) on rice plants Inpara 2 variety in Bokem Village. research conducted from August October 2022 fields Village, Merauke District. Sampling carried out three with an area 20 x 40 m divided by five observation sub-plots spread di...
this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this stud...
To study the effects of plant densities and planting orientation on the seed and forage yield of sorghum, an experiment was conducted at Hossein- Abad – Shahcal village –90 kilometers south of Bam-in 2002. The experiment was a factorial with randomized complete block deisgn and three replications. The treatments were: orientation with three levels (South-North, East – West, Northeast – Southwes...
