The experimental design was carried out in a randomized complete block with a factorial arrangement of treatments in three replications. Main plots included four different levels of density (6, 8, 10 and 12 plants per meter) and sub-factors included zeolite application (0, 10, 20 and 30 t/h). The obtained results showed that the effect of compression at a rate of stem diameter, number of rows per corn, number of seeds per row, 1000-seed weight, biological yield, electrical conduction and the extinction coefficient at the level of 5% on plant height and seed yield was significant. In addition, the results showed that effect of zeolite on biological yield, chlorophyll b and total chlorophyll at the level of 1% and on the number of seeds per row, 1000-seed weight and extinction coefficient at the level of 5% was significant. Comparison of the results suggests that the use of zeolite with different densities of 20 t/ha with a density of 8 plants per square meter would be the highest yield and yield components.

A 5‐year‐old female Holstein cow with a raised mass at the base of right ear was referred. On gross examination, the mass was approximately 13.00 × 10.00 × 7.00 cm in size. Finally, complete surgical removal was selected. The mass was encapsulated and the dermis was expanded by spindle‐shaped to polygonal neoplastic cells. These cells were arranged in interwoven pattern. Mitotic figures were infrequent. Masson's trichrome demonstrated the positive and blue staining of collagen. Immunohistochemically, the sections were uniformly positive for Vimentin and negative for Desmin, SMA and GFAP. A well‐differentiated fibrosarcoma was diagnosed based on histopathological features. Surgical excision is the treatment of choice for this neoplasm. In the present case, surgery was also performed successfully and no new gr...

The first factor was drought stress including lack of drought stress, irrigation cut in podding stage and irrigation cut in grain filling stage as the main plot and the second factor was vermicompost including non-consumption, vermicompost with cattle litter, vermicompost with cattle and equine litter, as well as vermicompost with cattle, poultry and equine litter as sub plot. Based on the results of analysis of variance, the main effect of drought stress and grain yield vermicompost, biological yield, protein yield, proline and cell membrane stability was significant at one percent probability level. Additionally, drought stress was significantly effective on pro...

Occurrence of gypsum in studied soils related to weathering the parent material and climatic conditions. In all pedons were observed secondary gypsum in small crystalline with diameters of a few millimeters and in different forms. Gypsum content showed an increase with depth in middle of all pedons and then its content decrease in lower horizons. The XRD diffractograms indicate the presence of chlorite, smectite, illite, palygorskite and kaolinite as the major clay minerals in these soils. Chlorite, illite and kaolinite can be originated from parent material. The amount of smectite in the clay fraction increased with depth except in pedon 5 and as for smectite, palygorskite showed an increasing trend with depth in the pedons 2, 4. Probably inheritance and transformation from illite are the main ways for existence of smectite. Neoformation of palygorskite is believed to be the main mechanisms for the occurrence of this mineral in the studied soils.
