In order to investigate the effect application of mycorrhizal fungus and potassium fertilizer on trait of Black Cumin (Nigella sativa) in different irrigation levels, an experiment was conducted as split factorial based on randomized complete block design (RCBD) with 3 replications during 2018-2019 in Marvdasht city. Four irrigation levels with 100, 75, 50 and 25% of field capacity were considered as the main plot and application and non-application of mycorrhizal fungus, application and non-application of potassium fertilizer as a factorial in the sub-plot. Analysis of variance indicated that the effects of irrigation, mycorrhiza, potassium, and also the interaction between irrigation and mycorrhiza on the studied traits were significant. With increasing of drought stress, plant height, number of lateral branches, number of follicles per plant, grain yield, biological yield and oil yield was decreased. The highest grain yield related to irrigation 100% of field capacity in the application of mycorrhizal (856 kg/ha) and the lowest grain yield was obtained irrigation with 25% field capacity in non-application mycorrhizal (174 kg/ha). Also, the results indicated that the application of mycorrhizal in treatment irrigation with 75% of field capacity led to an increase in traits of Black Cumin and there was no significant difference with 100% field capacity irrigation and no application of mycorrhizal treatment. In the 25% field capacity of irrigation, no significant difference was observed between the application and non-application of mycorrhizal for most traits of Black Cumin. Manuscript profile

In order to evaluate selective herbicides at different times on wild oat control in wheat field, a factorial experiment in terms of randomized complete block design (RCBD) with four replications was conducted at Marvdasht, Fars during planting seasons in 2011-12. Four selective and common herbicides (Atlantis OD (mesosulfuron-methyl and iodosulfuron-methyl-sodium), Total (metsulfuron methyl and sulfosulfuron), Topic (Clodinafop propargyl( and Puma Super (Fenoxaprop-p-ethyl) and four application times (6-8 leaf stage of wheat, early tillering, mid-tillering and early jointing stage) were considered as the first and second factors, respectively. Results showed that there was significant difference between the times of application and selective herbicides to control wild oat weeds (p > 0.05). The results of mean comparison in relation to the application times revealed that the highest and the lowest control levels of wild oat weed were in the stages of mid-tillering and early jointing, respectively. The findings in relation to the selective herbicides also showed that the highest dry weight (DW) of weeds was obtained in both of Topic and Puma Super herbicides. The lowest DW of wild oat weed was observed in both Atlantis OD and Total herbicides. The results of yield and yield components showed that the highest grain yield obtained when the herbicide was applied at mid-Tillering stage. Herbicide application at the jointing stage due to lack of proper control of weeds led to a decrease in wheat yield level. Application of Atlantis OD herbicide at 6-8 leaf stage of wheat can cause severe burning of wheat and thus may decrease its yield. In general, it is recommended that acetyl coenzyme A carboxylase family of herbicides which has a high degree of resistance to weeds not to be used. Manuscript profile

Innovations for saving water in irrigated agriculture and thereby improving water use efficiency are of paramount importance in water-scarce regions. Therefore, to see how restricted irrigation systems and different potassium and zinc fertilizer affect water use efficiency and yield of corn, an experiment was conducted in an arid area in Marvdasht, Iran in 2012. A split-Factorial experimental design was used based on a complete randomized block design with three replications. The main plots consisted of two irrigation methods: FI (full irrigation) and partial rootzoon drying (PRD). Each subplot received three rates of K fertilizer application: 0, 2.5 or 5 kg ha-1 and three rates of Zn fertilizer application: 0, 2.5 or 5 kg ha-1 .The results showed that the plots receiving the full irrigation resulted in significantly higher grain yields, 1000-kernel weight and grain number per cob than PRD treatment. However, the highest WUE and IWUE were obtained in PRD, 5 kg K ha-1 and 5 kg ZN ha-1 and the lowest one was found in the FI treatment .In general, PRD irrigation method at high level of potassium and zinc fertilizer improved WUE and decreased WU in corn to 40% in an arid region.
