In order to evaluate response of quantity and quality traits of forage maize to macroelements and zinc in the common agricultural and ecological systems, an experimental carried out as split plot design a randomized complete block with four replications in the village of Qara-Chai that khondab city located. The main plots included in organic and chemical fertilizer treatments at six levels: 100, 75 and 50% NPK fertilizer recommended by the laboratory, 75% NPK fertilizers 10 t/ha manure, 50% fertilizers NPK 25 t/ha manure, 40 t/ha of manure, and subplots sprayed with different concentrations of zinc sulfate in three of control (no spray), sprayed with zinc sulphate two and four per thousand. Results showed that maximum forage yield 92291 kg/ha was recorded from 40 t/ha manure that with 75% NPK fertilizers combined with application of 10 t/ha manure with forage yield equal to 88845 kg/ha was no significant difference. The foliar application of zinc at a concentration of 4 per thousand, the highest yield (87379 kg/ha) were produced. The highest protein content (12.59 %) was obtained from treatment 40 t/ha of manure. The foliar application of zinc sulfate at concentration of 4 per thousand showed that highest protein content (18.73%). foliar application of two and four per thousand zinc sulfate concentrations increased the grain yield by 8, 9 and 23.08 % compared to the control. The maximum of zinc concentration (47.13 mg/kg) was recorded from application of zincsulfate at the rate of 4 per thousand. In general, results showed that application of 75% NPK recommended combined with 10% t/ha manure along with foliar application of 4 per thousand zinc sulfate can obtain good quantitative and qualitative yield.

In order to study the effect of nitrogen fertilizers and manure on grain yield and yield components, a field experiment was conducted in the Agriculture Research Field, Babolsar, Iran, in 2012 crop season. This experiment was carried out with two factors, in a split plot arrangements using Randomized Complete Blocks Design (RCBD) with 3 replications. Manure (Cow) fertilizer (10, 20, 30 t/ha) were assigned to main plots and Nitrogen fertilizer (0, 50, 100, 150 kg/ha) were randomized in sub plots. The results indicated that the use of nitrogen fertilizer on traits such as plant height, cob diameter, number of grains per ear, grain yield, 1000- grain weight and biological yield was significance at 5% level. The highest and lowest grain yield was obtained from 150 kg N/ha and without application of nitrogen respectively. The different amounts of nitrogen fertilizer on traits such as ear length, number of rows per ear, cob length and harvest index were not significant. Manure application had not significant effect on any traits, except number of grains per ear,1000- grain weight and harvest index. Manure treatments were not significant due to de composition gradually and therefore can not release enough nutrients, especially nitrogen. The manure should be added to the soil for several consecutive years to show its effect on soil and plants. The interaction of nitrogen fertilizer and manure on ear diameter and biological yield at 5%level should significant effect. The highest grain yield was produced from 30 ton/ha farm yard manure (FYM) +100kg N/ha treatments.

In order to investigate irrigation intervals effect of irrigation intervals, manure and zeolite traits of agronomical and yield of potato varieties Agria on experiment was conducted in moradi field in 5km Arak-Farahan in 2010. The exprimental design was split plat on randomized complete block design with four replications. The treatment applied, including irrigation at three levels 6 days, 8 days and 10 days as main plot and in sub plots treated manure and zeolite four levels include: control (no use of manure and zeolite), 20 ton/ha of manure + 4 ton/ha of zeolite, 40 ton/ha manure and 8 ton/ha zeolite. The results showed that application of manure and zeolite on traits of measured at 1% level of probability was significant.with increasing of irrigation in terval from 6 to 8 day, yield reduced by 7/19 % declined. Main effects of manure and zeolite showed the highest tuber yield equivalent of 59/88 ton/ha from 20 ton/ha manure +4 ton/ha zeolite was obtained. Effect of interaction showed that the highest tuber mean total yield equivalent product 63/6 ton/ha from irrigation six days and application 20 ton/ha manure+4 ton/ha zeolite was obtained that with tretmant of irrigation interval 8 day and application along with 20 ton/ha manure+4ton/ha zeolite was not significantly.

Today, the use of organic fertilizers is increasing. The humic substances are a mixture of various organic compounds that are derived from the remains of plants and or animals.Humic acid is one of the compounds that today are widely used in research as well as commercial uses. The plant grown in soils that have enough humic substances, are less influenced by stress, will produce healthier plant and more product. Summer Savory (Satureja hortensis L.) is an annual plant that is widely cultivated. Essential oil of this plant has antimicrobial properties and inhibits the growth of some bacteria. All vegetative shoots contain essential oil which has antimicrobial, anti-oxidant and anti-fungal. In order to investigate the organic matter of humic acid in comparison to chemical fertilizer and manure, a research was carried out in years 2009-2011 for 3 years in Khojir research station a form of a randomized complete block design with six treatments and 3 replications. The treatments included humic acid, fertilizer (N100P80K100), manure (30 ton/ha), humic acid mixture with half fertilizer, humic acid mixture with 10 tons/ha of manure compared with the control. According to the results, the use of humic acid increased significantly in most of the studied traits such as root length, plant height, number of lateral branches, leaf dry weight in plant, shoot dry weight, shoot fresh weight, dry shoot yield, essential oil yield, seed yield compared to control. Chemical fertilizer with 28.88 kg, manure with 27.41 kg, humic acid with 23.34 kg, mixture of humic acid with chemical fertilizer with 22.19 kg and mixture of humic acid manure with 22.92 kg per hectare had significantly increase in essential oil yield than the control group (16.87 kg). Thus in summer savory cultivation, the humic acid consumption due to increased dry matter yield and essential oil yield, is recommended.

In order to effect nitroxin levels of nitrogen and manure application on nitrogen use efficiency and some quantitative traits in sweet corn varieties as Chase factorial experimental design based on randomized complete block with three replications in agricultural research farm in 2010، Islamic Azad University Arak was performed. Factors studied include two levels nitroxin inoculated and non inoculated with the seed، pure nitrogen at three levels 0، 50 and 100 kg ha-1 and manure at three levels 10، 20 and 30 tons ha-1 were. The results showed nitroxin on the characteristics of grain per ear، ear away from the field level، cob weight، grain yield and nitrogen use efficiency had the effect، so that the increase of grain per ear، cob weight، grain yield per hectare and nitrogen use efficiency was. Animal manure also on the characteristics of grain per ear، ear away from the field level، ear leaf area، grain hectolitre weight، grain yield per hectare and nitrogen use efficiency had the effect، so that reduces the nitrogen use efficiency and grain per ear was. Nitrogen effects on grain protein، cob weight، ear leaf area، grain yield and nitrogen use efficiency was significantly increased grain protein and grain yield per hectare was. Excess nitrogen and manure significantly reduced nitrogen use efficiency was also inoculated seed nitroxin positive effect on nitrogen use efficiency found.

In order to study effect of water deficit stress and manure onon quantitative and qualitative yield and some characteristics of physiologicalof plantago ovate a pot experiment was performed at the greenhouse of Jiroft Islamic Azad University, Iran, in 2009. For this purpose split plot design based on complete randomized block with 3 replication was used. Irrigation treatments consist of 3 level: 75%FC (mild stress), 50%FC (Medium stress) and 25%FC (Sever Stress) were main factors and manure levels (0, 10, 20, 30 and 40 ton/ha) were selected as sub factors. The results showed effect of water deficit stress and manure and also interaction effect between two factor on seed yield were significant (P<5% and p<1%). Highest seed yield (232.3 kg/ha) obtained from mild stress with using 20 ton/ha manure. This two factor had no significant on mucilage. With increasing water deficit stress RWC was decreased. The maximum RWC obtained by using 40 ton/ha. Cell membrane stability was decreased under sever stress. Thus in Jiroft it's necessary for reach high yield in plantago ovata 20 t/ha manure.
