“…Its low E and high P n support this conclusion [39]. S. longistamina and U. pumila have higher Ψ and WUE with lower E, which suggests their better water relations under water-limited conditions, and their suitability for afforestation in the Qinghai Tibetan Plateau [40]. Adversely, WUE of P. cathayana is lower because of its higher P n and E. The higher g s of P. cathayana may result in higher E. It opens stomata to assimilate carbohydrates rapidly at first then closes to avoid water loss.…”

This paper measured the ecophysiological responses of Populus cathayana Rehd., Salix longistamina C. Wang et P. Y. Fu., and Ulmus pumila L. to high altitude in the Tibetan Plateau based on changes in water relations, gas exchange, and chlorophyll fluorescence. P. cathayana and U. pumila have higher survival rates than S. longistamina, but the latter has highest biomass. S. longistamina has higher water-use efficiency (WUE), lower transpiration rates (E), higher water potential (Ψ), highest light saturation point (LSP) and higher photosystem II (PSII) photochemistry efficiency (F v '/F m ') and non-photochemistry quenching (NPQ) than the other species, and is thus adapted to its habitat for afforestation. U. pumila has lower E, light compensation point (LCP), dark respiration (R d ), F v '/F m ' and electron transport rate (ETR), with higher Ψ, apparent quantum yield (AQY), net photosynthetic rate (P n ) and non-photochemical quenching (NPQ), which helps it maintain water balance and utilize weak light to survive at high altitude. Relative low WUE, Ψ, R d , NPQ, with high E, P n , F v '/F m ' and biomass, imply that P. cathayana is more suitable for shelterbelt forests than for a semi-arid habitat. These three species can adapt to high-altitude conditions by different physiological mechanisms and morphological characteristics, which can provide a theoretical basis for afforestation and forest management in the Qinghai Tibetan Plateau.

“…In experiments conducted in southeastern Poland, dry matter yield of Sida hermaphrodita depending of soil quality, nitrogen and phosphorus fertilization levels, and the year of cultivation ranged from about 2 to 17 Mg DM ha -1 [4,12,14,25]. The other hand in the experiment established in different parts of Poland yields were at a level 4-19 Mg DM ha -1 [10,[26][27]. In Lithuania the yield of Virginia mallow fluctuated between 4.7 and 7.5 Mg DM ha -1 [28].…”

“…Shoots reach a height of 200-400 cm and a diameter of 5-30 mm, they dry in autumn after the end of vegetation. Depending on field density and the method of establishing the plantation, soil and weather conditions, fertilization level, and average yields of Sida, just from the second year of cultivation, can reach 8-18 Mg (m 2 ) -1 of dry matter [3][4][5][6][7][8][9][10]. The level of obtained yields determines the economic and environmental efficiency cultivation and use of Virginia mallow biomass [11][12][13].…”

Although the domain role of agriculture is food production, a part of agricultural land has always been devoted to non-food products, mainly within the framework of emerging technologies. One of the plants that can be used for various non-food purposes is Virginia mallow (Sida hermaphrodita L. Rusby). Following this study it was found that Sida hermaphrodita yields less on poor soil and on soils of good quality, but is too heavy. This plant has best yields on good soils with proper water-air relations. Nevertheless, good yields were also obtained on poorer and medium-quality soils. This is particularly important from the standpoint of competition for land resources between production for food and non-food products. Achieving yield at 1-2 kg DM (m 2)-1 is possible in the case of plants that grow from 16 to 24 shoots for stumps with a diameter of 11-13 mm and a height of 2.2-2.6 m.

“…No matter the species or the cultivar, biomass production increased with annual rainfall. However, the extent to which precipitation affected yields depended on the species considered [28]. Generally, the RUE of warm-season grasses, such as switchgrass, is higher than cool-season grasses due to their different metabolism [49].…”

Long-Term Yield and Quality Performance of Perennial Energy Grasses (Agropyron spp.) on Marginal Land

et al. 2020

The cultivation of perennial grasses is one of the most desirable alternatives as energy feedstock, but it is difficult to achieve competitive yields under Mediterranean marginal conditions. The aim of this study was to assess the performance of three cool-season grasses (Agropyron spp.) from an agronomic and energetic point of view by comparing the dry matter (DM) yields, rain use efficiency, chemical composition, and biomass quality over an eight-year period in Spain under marginal rainfed conditions. The tall wheatgrass (Agropyron elongatum (Host) Beauv.) cultivars, Alkar (4.8 Mg DM·ha−1) and Jose (4.7 Mg DM·ha−1), achieved the highest yields. Productions below 0.5 Mg DM·ha−1 were obtained when rainfall was lower than 150 mm between March and June. The biomass obtained from the tested grasses showed relatively high contents of ash, silicon, and alkali elements. Net calorific values ranged between 16.7 and 18.5 MJ·kg−1 db. Differences in the composition among species and cultivars are not likely to affect their combustion behavior from a practical point of view. The ash content, as well as the concentrations of K, S, Na, and Cl, tended to decrease over the years. The results offered would be very useful for the implementation of this type of crop in marginal land.
