in order to increase grain yield, nitrogen use efficiency (nue) and nitrogen apparent recovery fraction (narf) in wheat (triticum aestivum l.), this experiment was carried out with 5 or 6 treatments and 3 or 4 replications in 14 locations at 22 different sites in iran during the 2004-05 growing season. the experiment was designed as a completely randomized block. the effect of n sources and tim...
To evaluate the effects of different levels of nitrogen (N) and salinity on yield and growth indices of tomato, a factorial experiment with a completely randomized design and three replications was performed in greenhouse conditions. Treatments included four levels of salinity (0.5, 2.5, 4.5 and 6.5 dS/m as NaCl) and four levels of N (0, 60, 120 and 240 kg/ha). The results showed that fruit yie...
In order to determine the interaction of residual nitrogen (N) and different N rates on seed and oil yield of rapeseed, an experiment was conducted at Shahrekord University, Shahrekord, Iran, in 2008-2009 growing season. The experimental design was split plots arranged in randomized complete block design with three replications. Seven treatments of residual N (217, 435 and 652 kg/ha from urea...
proper application of n fertilizer and its optimization for increasing the economic yield of rice is definitely important. in order to determine the best n application method and amount according to growth stages of hybrid rice, an experiment was carried out at experimental farm of rrii in a factorial experiment based on a randomized complete block design with 3 replications. the treatments inc...
Nitrogen (N) application management needs to be refined for low yielding environments under dryland conditions. This 3-yr study examined nitrogen fertilization management effects on corn (Zea mays L.) plant characteristics and grain yield in rain fed environment under conventional tillage system. Nitrogen fertilization management consisted of two timing methods of N application [all N at planti...
Intercropping is one of the effective components of sustainable agriculture. In order to assess the effects of nitrogen application and planting arrangement on linseed and berseem clover leaf area, light absorption and their yield an experiment was conducted as a split plot based on randomized complete block design with three replications at the Research Farm of College of Agriculture, Isfahan ...
in this research for study the effects of nitrogen fertilizer on yield and yield components of current rice cultivars was an experiment as factorial in rcbd with three replications where conducted during 2009 year in two locations (rice research institute, rasht, and rudsar, east of guilan). factors were cultivars (khazar, ali kazemi and hashemi), and nitrogen fertilizer levels (0, 30, 60, and ...
limited information is available on water and nitrogen (n) management of sugarcane (saccharum officinarum l.) in khuzestan, southwestern iran, where this crop is currently and extensively grown under heavy irrigation and n fertilization. therefore, a field experiment was conducted from september 2000 to march 2002 at the research department of karoon agro-industry in khuzestan to determine the ...
In order to investige the effect of nitrogen and Azospirillum biological fertilizers on the growth and yield of an Iranian bread wheat (Roshan cultivar) this study was carried out using a factorial experiment based on a randomized complete block design with three replications at a field in Jozan region, Isfahan, Iran in 2013. The experimental factors included Azospirillum brasilense bacterium a...
At the Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj, a field experiment was undertaken during Rabi season 2022. The soil texture experimental plot sandy loam, with pH 7.1, low organic carbon (0.28 percent), available N (225 kg/ha), P (19.50 and K (213.7 kg/ha). Rhizobium sp (20g/kg seed), PSB + (10g/kg seed 10g/kg seed) were used as bio-fertilizers, phosphorus (50 kg P2O5/ha, 6...
