To evaluate effects of FOLIAR APPLICATION of Fe AND Zn on morphology AND yield of anise, a factorial experiment was conducted using rANDomized complete block design with three replications at the Agricultural Research Station, Urmia University, Urmia, Iran, in 2008. Treatments were Fe AND Zn APPLICATION (0, 2, 4 AND 6 g.l-1). Results showed significant effect of Fe AND Zn on the number of branches AND the stem diameter, AND the interaction of Fe AND Zn on chlorophyll content, the number of seed.plant-1, biomass yield, seed yield was also significant. The highest SPAD value (chlorophyll content) (37.9) was observed at 6 g.l-1 of Fe AND Zn, AND the lowest value (15.3) was measured at 0 gl-1 Fe AND 2 g.l-1 Zn. The highest biomass yield (2652 kg.ha-1) AND seed yield (1372 kg.ha-1) was obtained from 6 g.l-1Fe AND 4 g.l-1 of Zn AND the lowest biomass yield (716 kg.ha-1) AND seed yield (470 kg.ha-1) belonged to 0 gl-1 AND 6 g.l-1 of Fe AND Zn, respectively. Results also showed that the highest essential oil yield (50 kg.ha-1) was obtained from 6 g.l-1 Fe AND 4 g.l-1 of Zn, AND the lowest essential oil yield (18 kg.ha-1) belonged to 2 g.l-1 Fe AND Zn. Homolen AND ESTRAGOLE was largest component both with 18% essential oil measured by gas chromatography analysis. It is concluded that FOLIAR APPLICATION of Fe increased seed yield, chlorophyll content AND essential oil yield of anise AND this was enhanced by FOLIAR APPLICATION of Zn.

In order to eliminate the overlapping time of rapeseed harvesting AND rice transplantation in Guilan province, AND to provide appropriate solutions to reduce yield losses through seed loss, the present experiment was conducted as a factorial plots in a completely rANDomized blocks design with three replications at the Rice Research Institute of Iran in Rasht. The main plots in the present experiment consisted of the interaction of two ethephon FOLIAR APPLICATION factors at two levels (non-consuming AND consuming 280 gram per hectare) AND FOLIAR APPLICATION time at three levels ( podding, early grain filling, grain filling completion) AND subplot including harvesting time in three phases, physiological maturation, 10 AND 20 days after the physiological maturity. The results showed that ethephon FOLIAR APPLICATION with a mean time of 192 days reduced 8 days growth period compared to control treatment with an average time of 200 days. Also, erosion time (194. 6 days) was higher than early grain filling (196. 3 days) AND seed filling completion with 197. 1 days for early maturity traits. The effect of harvest time on number of pods per plant, one-thousAND grain weight, grain yield, oil percentage was significant. According to the results, ethephon FOLIAR APPLICATION caused 12 percent increase in grain yield AND 0. 7 percent increase in oil in later harvestings. The interaction effect of FOLIAR APPLICATION, FOLIAR APPLICATION time AND harvest time on seed yield was significant. Ethethenol soluble FOLIAR APPLICATION at the time of podding, with the lowest grain loss, was 202. 8 kilogram per hectare as the best experimental treatment.

This study was carried out for investigating the effect of amount AND timing of FOLIAR urea in increasing silage yield AND protein content of fodder, in a maize field in Neyshabour, Khorasan Razavi Province during 2011 summer crop season. A split plot design with factorial arrangement AND three replications were used. Treatments were timing of FOLIAR urea APPLICATION (a week before tasselling, mid anthesis AND early milk stage), urea levels (zero (check), five AND 7.5 g.lit-1) AND two hybrids of corn (Sc 704) AND forage sorghum (speed feed). The results indicated that the concentration of nitrogen had significant effect to increase forage protein AND silage yield (correcting by 280 g.kg-1 of dry matter). The highest forage protein concentrations for both crops AND silage yield were achieved with 7.5 g.lit-1 of urea APPLICATION, but the silage yield of sorghum was more than that of corn. The results showed that urea spraying can effectively increase the fodder nitrogen AND silage protein, respectively, with the least possible cost, AND in this respect it has an important role in providing quality AND environmental safe forage for producer AND consumer, meanwhile the adverse effects of excessive use of nitrogen fertilizer are reduced.

To study the effects of irrigation AND nitrogen treatments on rapeseed (option 500 variety), an experiment was conducted at agricultural research station of Gonbad during 2003-2005.The station is located at 5 km east of Gonbad at an altitude of 45 meters above sea level AND has Xerothermo Mediterranean climate.The experiment was carried out as factorial form in RCBD with 3 replications. Iirrigation treatments included the check (without irrigation), irrigation at flowering stage, AND irrigation at flowering stage AND seed filling stage. The nitrogen treatments consisted of the control (no N), applying N to the soil without FOLIAR APPLICATION, AND applying N to the soil with FOLIAR APPLICATION. The FOLIAR APPLICATION of urea was applied in the beginning of stem elongation AND flowering stages with 2.5% concentration. The result of the first year of experiment showed that the effects of irrigation, nitrogen, AND the interaction between the two variables were significant on grain yield. However, the effect of irrigation in the second year was not significant because of high rain fall. The two-year analysis showed that the effect of year was significant on grain yield, the number of secondary branches, AND 1000 grain weight, reflecting that the climatic conditions varied in the two years of the experiment. Irrigation at flowering AND seed filling stages together with N APPLICATION to the soil AND FOLIAR APPLICATION treatment had the highest yield (3426 kg/ha). Therefore, irrigation of canola is recommended for the seasons when there is not enough rain at flowering AND seed filling stages.

To investigate the effects of paclobutrazol (PBZ) on vegetative AND reproductive growth of Strawberry cv. Selva a factorial experiment in a completely rANDomized design with three replications was carried out in greenhouse of Agriculture College, Isfahan University of Technology. PBZ was applied in two methods, drench AND FOLIAR spray, at 0, 0.5, 1, 1.5 AND 2 mg active ingredient per plant. The results indicated that APPLICATIONs of PBZ as FOLIAR spray was more effective than soil drench on vegetative AND reproductive growth. With increasing the amount of PBZ leaf area, shoot fresh weight, whole plant fresh weight AND petiole length of treated strawberries were decreased, however fresh weight, number AND diameter of roots were not affected by PBZ. Also PBZ had no significant effect on fruit firmness, total soluble solids AND vitamin C. The interaction of PBZ AND its method of APPLICATION on characteristics including leaf area, petiole length AND diameter, total fresh weight, shoot fresh weight, leaf chlorophyll content, yield, fruit diameter AND harvest index were significant. FOLIAR APPLICATION of PBZ at the rate of 2 mg active ingredient per plant lead to maximum value of petiole diameter, leaf chlorophyll content AND harvest index. Yield (fruit/plant) was also increased (27.16%) when the plants received 1 mg active ingredient per plant PBZ through soil drench method.
