A field study was conducted at Aboureihan research field of Tehran University in 2009 to find out the effect of nitrogen pellet fertilizer on the grain yield and nitrogen use efficiency of corn (Single Cross 704). The factorial design of the study comprised of randomized complete block with three replications. Factors of this experiment including: first factor was two levels of fertilizer appl...
effect of different amounts of foliar- and soil- applied n were evaluated in a factorial arrangement of rcbd with three replications at the agricultural research station of gorgan in 2004-2005 growing season. two promising lines of bread wheat, two levels of foliar application of nitrogen (0 and 5%) at tillering and booting stage, with five rates of 0, 45, 90, 135 and 180kg n/ha as urea were us...
To evaluate the effect of nitrogen slowly released from pellet, composed of manure and urea fertilizer on the Nitrogen efficiency and morphological Characteristics and grain yield of corn hybrid (S.C704), a field experiment was carried out in Aboureihan research farm of Tehran University in 2009. The factorial design of the study comprised a randomized complete block with three replications. Th...
Bush bean, long bean, mung bean, and winged bean plants were grown with N fertilizer at rates of 0, 2, 4, and 6 g N m(-2) preceding rice planting. Concurrently, rice was grown with N fertilizer at rates of 0, 4, 8, and 12 g N m(-2). No chemical fertilizer was used in the 2nd year of crop to estimate the nitrogen agronomic efficiency (NAE), nitrogen recovery efficiency (NRE), N uptake, and rice ...
In order to study the effects of terminal heat stress and nitrogen on morphophysiological characteristics, ANUE (Agronomical Nitrogen Use Efficiency) and yield of canola, an experiment was conducted at research farm of Ramin Agricultural Sciences and Natural Resources university. The experiment was arranged in split plots based on randomized complete block design with four replications. Main pl...
In order to evaluate the effect of potassium sulfate fertilizer and ascorbic acid application on yield and yield components and growth of quinoa (Chenopodium quinoa Willd.), a field experiment was carried out at 2018-2019 at Isfahan, central Iran. A factorial experiment based on a randomized complete block design with three replications was used. Experimental treatments were potassium sulfate i...
to study the effects of mycorrhiza fungi and humic substances on yield and yield components of corn (zea mays l. var. s.c. 704) under limited irrigation condition, an experiment was conducted in split plot arrangement based on rcbd in four replications at the research farm of university of tehran (karaj-iran) in 2011. the main factor consisted of three irrigation levels i.e. normal (irrigation ...
Variable rate application of fertilizer has the potential to improve nutrient use efficiency, improve economic returns, and reduce negative environmental impacts. The objective of this study was to evaluate the variable rate application of potassium fertilizer to soybean crop in a no-till system. The study was conducted on a 13-ha soybean grain field in Carambeí, State of Paraná, Brazil in a Ty...
Grain yield of bread wheat (Triticum aestivum L.) is reduced by heat stress, particularly when occurs in reproductive phase, in many countries worldwide, including Iran. In order to study the effects of different levels of nitrogen and cytokinin on wheat yield and yield components at normal and heat stress conditions in Khuzestan, Iran, this research was conducted at Ramin Agriculture and Natur...
A field micro-plot experiment using nitrogen isotope (15N) labeling was conducted to determine the effects of placement methods (broadcast and band) and N rates (60, 150 and 240 kg ha-1) on the fate of urea-15N in the wheat-soil system in Guangde County of Anhui Province, China. N fertilizer applied in bands increased grain yield by 15% compared with broadcast application. The N fertilizer appl...
