Ferula assa-foetida L. is an important industrial and medicinal plant of Iran which is mainly distributed in arid and semi-arid areas of Khorasan province in north east of the country. Gum of this plant is widely used in pharmacological industry. This plant is endangered because of more harvesting and unsustainable harvesting methods. The objective of this study was to evaluate the effects of different cutting methods (conventional, cut of crown part, concave and surface) and times of cutting (5, 10 and 13 times) on gum yield of this species in its wild habitat in Mazar region in Bajistan. The treatments were studied under a factorial experiment which was arranged in a completely randomized design with three replications. Results showed significant differences among cutting methods and times of harvesting. Yield of gum was affected by times of harvesting and the highest yield was obtained in 10 cutting times. The highest and lowest gum yields were obtained in concave method with 10 cutting times (25.24 g/plant) and superficial method with 5 cutting times (2.02 g/plant), respectively. Results showed that conventional cutting method destroys crown buds, which causes death of the plant. The highest gum yields and the best plant regeneration rates were obtained by using of concave method with 10 cutting times.

Abstract Aims Finding how straw checkerboard barrier technology, as a sustainable and environment-friendly method, may affect soil chemical properties and water status despite wind erosion control directed us to evaluate this technique as a vital component of management plans in sloping lands of semi-arid areas. We were interested to know if it could support the soil capabilities to grow pilot plants and recover some ecological services via alleviate drought stress or amendment of soil attributes.Methods In order to study soil characteristic and growth performance of winter cover crops, an experiment was carried out in 2018. Checkerboards were setup in a 1×1 m pattern with rice residues. Seeds of sainfoin (Onobrychis sativa), rye (Secale montanum) and tall wheatgrass (Agropyron sp) were sown at the checkerboards and bare ground as the control. Detailed analyses include growth characteristics, physiological attributes i.e. photosynthetic pigment contents, proline and malondialdehyde contents and relative water contents of mentioned crops and the related soil properties during the growing season were carried out in borders and centers of the straw checkerboards and bare ground.Results Soil covered with straw checkerboard barriers was the most effective for improving vegetation growth and establishing taller plants with higher biomass. Based on the physiological analyses, the rye grown in straw checkerboard plots coped well with dry conditions. Higher proline content and more efficient osmotic adjustment indicates improvements of soil water retention status, which may alleviate drought stress damages and improve cover crop performance in straw checkerboard plots. Photosynthetic pigments also showed higher contents in checkerboards for rye. Soil organic matter, total nitrogen, available phosphorus, potassium and water storage increased in checkerboards too, however, such effects vary with the crop type. Conclusions straw checkerboards could be deemed as an effective management strategy in semi-arid areas, as an important method for conserving natural resources and sustaining productivity.

Browse species are important food resources in semi-arid areas, especially during the dry season when the nutritive value of grass is at its lowest. However, browse plants often contain secondary plant compounds which limit their nutritive value. Proanthocyanidins (PAs) (also called condensed tannins) and related flavonoids are a common constituent of woody plants in tropical regions (Mangan, 1988). PAs cause a bitter and astringent taste which lowers food palatability and they also lower the digestibility of proteins and carbohydrates (Jacksonet al., 1996). PAs also interfere with current chemical methods that are used for estimating nutritive value of foods (Reed, 1995). Biological assays, especially ,in vitrotechniques, have a potential to reflect better the nutritive value of foods that contain PAs. Thein vitrogas production technique has been found to reliably predict the nutritive value of temperate forages (Makkaret al., 1996). There has been limited research on its efficacy with tropical forages. The experiment reported here was conducted to test the hypothesis that gas production of tropical browse species reflects their content of fibre, protein and/or PAs.
