katoul is a new soybeam cultivar originated from a genotype named d.p.x.3589 imported from the united states of american in 1990. this genotype was examined together with other soybean genotypes and check cultivars in different preliminary and advanced yield traits in gorgan and other research stations during 1999-2002. the mean seed yield of d.p.x.3589 in all these experiments was 3333 kgha-1 ...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
Rice cultivation has been challenged by increasing food demand and water scarcity. We examined the responses of water use, grain yield, and water productivity to various modes of field water managements in Chinese double rice systems. Four treatments were studied in a long-term field experiment (1998-2015): continuous flooding (CF), flooding-midseason drying-flooding (F-D-F), flooding-midseason...
Extended Abstract Introduction and Objective: Due to the lack of micronutrient elements and the urgent need for biofortification in important and strategic plants in the nutrition of human society such as wheat, it is necessary to evaluate any strategy to optimize the quality and production of this product. This has led researchers to investigate the effect of foliar application of zinc and ir...
Abstract Eleven wheat cultivars were evaluated at 10-day intervals, beginning from anthesis, under irrigated and drought stress conditions during 2006-2007. The effects of irrigation, genotype and date of harvest were significant for most of the studied characters. Water deficit decreased pre-and post-anthesis assimilation rate, grain weight per spike, grain number per spike and 1000 grain wei...
A factorial experiment, based on RCB design, with three replications was conducted to evaluate the effects of rhizobial inoculation, urea, and weeds on soybean performance in the field. The factors under study consisted of inoculation and non-inoculation, three levels of 0, 150, and 300 kg/ha urea, and weed-control and weed-infestation. Results showed that weed-control, inoculation and urea a...
Only leaf reduction (Cultural measure), in treatment T4 [treated with removal above 15 inches (38.10 cm) from ground level], maximum yield (2185.00 kgha-1) was found resulted 21.64% more over the control. T3 [10 (25.40 cm)] and T5 [20 (50.80 gave similar response having 20 20.68% increased The lowest severity (21.38 PDI) that statistically identical to [15 a decrease trend of 58.28%, 50.26% 42....
in order to study effect of foliar application of iron and zinc on yield and yield components of autumn rapeseed (brassica napus l.) under limited irrigation an experiment was conducted at research farm of agricultural faculty of urmia university in 2009. the experiment was designed in split plot based on randomized complete block design with 3 replications. treatments were drought (irrigation ...
to study the effects of zabol wastewater treated with two kinds of fertilizer (manure and chemical fertilizer) application vs use of ordinary water on grain yield and yield components in corn (kosc704) a field experiment was conducted at the university of zabol, iran during 2007 growing season. the statistical plan selected was a split plot one of three replications. the treatments were compris...
