Natural products have played a key role in drug discovery and development in modern days. Sulforaphane can be found in a wide variety of cruciferous vegetables, including cabbage, Brussels sprouts, cauliflower, broccoli, Chinese broccoli, broccoli sprouts, broccoli raab, Kohlrabi, collards, kohlrabi, mustard, turnip, kale and radish. The most important health benefits of sulforaphane is its effects again breast cancer, lung cancer cells, human liver cancer cells, gastric cancer cell lines, ovarian cancer, prostate cancer, pancreatic cancer, colon cells cancer, treatment of cancer cell senescence, anti-inflammatory properties, antineoplastic agent, reduction of placental and endothelial oxidative stress, potential in mixed granulocyte asthma, treatment of various neurological disorders, protection again skeletal muscle disease, anti-allergic and its impact against oxidative stress.

Pyrethrum is a perennial daisy grown commercially for the insecticide that is extracted from its flowers. In order to evaluate germination and seedling growth of pyrethrum under different temperature and drought stress treatments, an experiment was conducted in seed technology laboratory of Faculty of Agriculture of Islamic Azad University of Isfahan branch in 2018. During this experiment, polyethylene glycol (PEG) at 6 levels (0, -0.2, -0.4, -0.6, -0.8, -1.0 MP) and two temperature treatments (10oC and 15oC) were used. Two separate factorial trials, on the basis of absolute randomized design with three replications were used. Drought stress impact on germination percentage, mean time germination, shoot and root length, abnormal germination, germination uniformity, plumule dry and fresh weight, root dry and fresh weight and seed stamina index was significant. The influence of temperature was meaningful on germination percentage, mean time germination, shoot and root length, plumule dry weight, plumule fresh weight, root dry weight and root fresh weight. The rate of germination, germination percentage, as well as seedling growth and establishment were significantly lowered with the rise of stress levels using PEG. Control treatment and 15oC had obtained the highest germination percentage, mean time germination, shoot and root length, germination uniformity, plumule dry and fresh weight, root dry and fresh weight, and seed stamina index. Taking all traits into account, a clear understanding of the germination responses of seeds is useful in screening for tolerance of species to extreme temperatures.

An appropriate sustainable agricultural technology system is an important technical support of the promotion of sustainable agricultural development. Properly management of residues can warrant the improvement of sustainability in crop productivity. The research was conducted in 2011 at Experimental Field of Islamic Azad University, Isfahan (Khorasgan) Branch, Isfahan, Iran. A strip layout randomized complete block design with three replications was used. The experiment was related to the effects of green manures of barley, rye, triticale and clover ,two levels of farm yard manure, namely, 30 and 60 t/ha and one treatment of chemical fertilizer as a control treatment were arranged in main strip and decomposition time of manures in two levels, one and four weeks after returning. Cover crop had significant influence on stem diameter, ear height, final plant height, leaf and stem fresh weights, stem and ear dry weights, fresh forage yield, nitrate leaf and protein content. Moreover, fresh forage yield, biological yield, of leaf nitrate, nitrate of stem, protein and ash were influenced by different managements. The highest plant height, leaf, stem fresh weight, ear and, stem and ear dry weight were related barley green manure treatment. The maximum stem diameter, plant height, ear fresh weight, leaf, stem and ear dry weights were obtained in the treatment of four weeks fo residue retention. The highest biological yield and fiber percentage of forage corn were observed in the treatment of residue retention for four weeks and crop residue incorporation, respectveily. Besides, there were no signfiicant differences for these both experimental characteristics between mentioned above treatments and residue burning. The highest fresh forage yield, protein and ash percentages were achieved in residue burning treatment. In conclusion, it seems that residue burning accompained with usage of triticale as a green manure was the best choice to achieve high quality, but for obtaining the highest fresh forage yield and biological yield of forage corn, triticale plantation can be replaced by barley.
