Relationships of foliar carbon isotope composition (δ(13)C) with foliar C, N, P, K, Ca, Mg contents and their ratios of 219 C3 species leaf samples, obtained in August in 2004 to 2007 from 82 high altitude grassland sites on the Qinghai-Tibet Plateau China, were examined. This was done with reference to the proposition that foliar δ(13)C increases with altitude and separately for the life-form ...

The experimental study is done for technological parameters of high-melting metal arc spraying to study the influence of spraying current, spraying voltage and wire feed voltage on spraying arc and the influence of spraying current on coating temperature and analyze theoretically the distribution rules of spray gun jet speed field and temperature field and their influencing factors. The results...

Strawberries are rich in antioxidants and plant components to enhance cardiac health regulate blood sugar. This experiment investigates the effects of N fertilization foliar spraying with calcium (Ca) boron (B) on growth, chemical composition foliage, fruit yield, quality strawberry plants (Fragaria × ananassa Duch. cv. Fortuna). includes 12 treatments from combination between four fertilizers ...

Salinity stress is one of the potential threats that adversely affect productivity many cereal crops worldwide. Spraying plants with nano-Zn particles may lessen effectively such negative impacts on plants; yet its mode action still not well explored. This study was performed to evaluate effects spraying varying concentrations (0, 20, 50 and 80 mg L−1) two wheat cultivars irrigated saline water...

The interest in expanding the production of hops outside traditional cultivation regions, mainly motivated by growth craft brewery business, justifies intensification studies into its adaptation to local growing conditions. In this study, four field trials were undertaken on a twenty-year-old hop garden, over periods up three years assess effect important agro-environmental variation factors ph...

Background Humic acid (HA) is an organic that naturally present in soil matter and improves nutrient availability the mechanisms involved plant growth development. Likewise, salicylic (SA) important hormone regulation of A pot experiment was carried out to determine effects individual or combined HA SA application on yield maize (Zea mays L.) under drought stress conditions. Two hybrids, namely...

Paddy soil contaminated by cadmium (Cd) has attracted worldwide attention, while foliar spraying of zinc (Zn) could be considered a cost-effective and practical agronomic measure for reducing Cd accumulation in rice grain. However, the effects due to Zn on different cultivars, as well mechanism subsequent processes taking place are not fully understood up now. To go step ahead, field experiment...
