This study was conducted to investigate the effect of organic growth Stimulator on growth and yield of rapeseed (Dalgan cultivar) under drought in university of Zabol (Chahnime) during 2017as split plot design based on RCBD with three replications. The treatments consisted of irrigation cut off levels based on the phenological growth stages (Sylvester-Bradley encoding system): I1 = control (complete irrigation), I2 = irrigation up to stage the growth rate code is 2.20 (twenty internally identified) and I3 = irrigation to stage the growth rate code is 5.9 (all pods are more than 2 cm long) and subsidiary factor consists of four levels of fertilizer : F1 = control (pure water solution), F2 = Hamoon Green 1 liter at 10 liter + calcium, F3 = Hamoon Green 1 L at 20 liter + calcium, F4 = Hamoon Green 1 liter at 30 liter + Calcium. The results showed that I2 caused a significant decrease in plant height, stem diameter, number of pods, number of seeds per pod, 1000 seed weight, grain and biological yield and oil percentage, and also F2 increased the above traits except the percentage of oil. Interaction effects showed that the highest amount of chlorophyll a, b, total, carotenoid, selenium and calcium content of grain obtained from I1F2. The highest amount of proline in I2F2 observed. The highest of these traits was obtained from F2. Generally, spraying of the organic growth stimulator can be moderates the harmful effects of drought stress in rapeseed and 27% improved seed yield.

An experiment was conducted to examine the effects of different tillage systems and fertilization on quantitative and qualitative characteristics of cumin as split randomized complete block design with three replicates in Delfan during 2016. Main plot included three different tillage system; 1( conventional (mold board plough, chisel plough and disk), 2 (minimum tillage (chisel plough and disk) and 3( zero tillage (disk) and subplots comprised eight different combinations of organic and chemical fertilizer; 1) control, i.e. without any dose of manure and fertilizers, 2) 25 kg N ha-1, 3) 10 ton vermicompost ha-1, 4) 20 ton cow manure ha-1, 5) 20 ton municipal solid waste compost ha-1, 6) 50 percent dose of chemical fertilizer (N) + 50 percent vermicompost, 7) 50 percent dose of chemical fertilizer (N) + 50 percent cow manure and 8) 50 percent dose of chemical fertilizer (N) + 50 percent compost. Results indicated that the highest grain yield (81.53 g/m-2) and biological yield (210.41 g/m-2) achieved in minimum tillage and application of cow manure, while the least quantities of these parameters was observed in zero tillage and control. In addition, the greatest essential oil percentage and yield attained in minimum tillage and application of 10 ton vermicompost, which was 25 and 28 percent greater than control. The results suggested that to improve the quantitative and qualitative characteristics of cumin application of manure and vermicompost along with minimum tillage is recommended.

To investigate the effect of nanofertilizers functionalized with two organic compounds in phosphorusreleasing and its influence on the growth parameters of bean plant, a factorial experiment was conducted based on a completely randomized design in 3 replicationsat the Agriculture Research Center of Hamadan in 2014. Fertilizer treatments including P0 (zeolite without functional group (control sample)), P1 (zeolite + AcAcEN ligand), P2 (zeolite + HED ligand) and P3 (triple super phosphate) and also twotypes of bean including the red beans (PhaseolusvulgarisL) and cowpea (Vigna unguiculataL.) were used. Results showed that in comparison with two other zeolite fertilizers,usingnanozeolite functionalized with HED ligandresulted in improving the quantitative and qualitativeparameters of bean. Compared with triple super phosphate, P2 fertilizer showed better results in the case of grain yield and plant phosphorus uptake and moreover, phosphorus leaching was lower in this fertilizer. The general results of this report is representative of the useful and effective role of nanozeolite functionalized with HED ligand in improving the growth parameters as well as qualitative and quantitative characteristics of bean plant.

In order to investigate effectsof different fertilizers on reduce negative effects of drought stress in chicory (Cichorium intybus L.), manure and poular fertilizers, Nano potassium and potassium sulfate were used on morphophysiological characteristics of chicory under drought stress. This experiment was carried out in a factorial plot based with a randomized complete block design in three replications at the Agricultural Research farm of Zabol University in 2014-2015. Water stress treatments included 60, 90 and 120 mm water evaporation from evaporate pan class assigned to the first plots and different types of fertilizers included manure and poular fertilizers were applied at 30 ton/ha, and nano potassium (27percent) and potassium sulphat were applied 10 and 150 kg. Results showed that drought stresses were decreased the growth characteristics significantly, while application of different fertilizers were decreasing the negative effects of drought on growth characteristics, especially two organic fertilizers are effective on reduce the negative effects of drought. Also, the highest plant height, flower diameter, flower number, lateral branches, flower yield and shoot yield were obtained at manure fertilizer treatments. Strong stress was showed the lowest content of chlorophyll a and b significantly, but carotenoids and anthocyanin are increases. Application of manure fertilizer improve a / b chlorophylls, and carotenoids significantly under drought stress. So the highest anthocyanin obtained at Nano potassium treatment. Different fertilizer treatments have had significant effects on antioxidant enzymes activities in comparison with control treatment.
