“…The lowest P content in tomato leaves was obtained from the application of K, P, and Ca to the saline nutrient treatment. According to Mashhady et al (1982), a considerable increase in P concentration occurs up to 6 mS/cm then decreases rapidly with increasing salinity. According to Joshi (1984), P content is lowered under NaCl and Na2SO4 salinities in the leaves of pigeonpea but not below the deficient mark.…”

The effect of salinity on the growth and yield of tomato plants and mineral composition of tomato leaves was studied. Five tomato (Lycopersicon esculentum Mill) cultivars, Pearson, Strain B, Montecarlo, Tropic, and Marikit, were grown in sand nutrient culture. The nutrient solutions applied consisted of a modified half-strength Hoagland solution with 50 mM sodium chloride (NaCl), 3 mM potassium sulphate (K 2 SO 4 ), 1.5 mM orthophosphoric acid (H 3 PO 4 ), and 10 mM calcium sulphate (CaSO4). Stem height and number of leaves of tomato plants were not found to be significantly different but leaf and stem dry weight were reduced significantly in plants irrigated with saline nutrient solution in contrast with control plants. The total yield was reduced in plants that received saline treatments, but there was no significant difference in fruit number and fruit set percentage. The fruit electrical conductivity and total soluble solids were increased in plants irrigated with saline nutrient solution. Fruit pH was not found to be significantly different among salinity treatments. Mineral composition of tomato leaves were increased by addition of potassium (K), phosphorus (P), and calcium (Ca) to the saline nutrient solution. The addition of K to the solution resulted in an increase in sodium (Na) leaf content. The amounts of K and magnesium (Mg) were not significantly different among salinity treatments. Calcium content was increased when CaSO 4 was added. Application of H 3 PO 4 resulted in the highest amount of P in tomato leaves under saline conditions. The present study revealed that application of K, P, and Ca

“…In addition, high salinity also directly affects the N absorption and utilization of plants. Mashhday et al (1982) thought that salinity significantly affected the N absorption of wheat and triticale, and the N utilization efficiency decreased gradually with increasing salinity. Paramita et al (2007) even found that the photosynthetic N-use efficiency of mangroves was significantly affected by salinity.…”

From April 2008 to November 2009, the nitrogen (N) cycle of plant-soil system in seepweed (Suaeda salsa) wetland in the intertidal zone of the Huanghe (Yellow) River estuary was studied. Results showed that soil N had significant seasonal fluctuations and vertical distribution, and the net N mineralization rates in topsoil were significantly different in growing season (p < 0.01). The N/P ratio (9.87 ± 1.23) of S. salsa was less than 14, indicating that plant growth was limited by N. The N accumulated in S. salsa litter at all times during decomposition, which was ascribed to the N immobilization by microbes from the environment. Soil organic N was the main N stock of plant-soil system, accounting for 97.35% of the total N stock. The N absorption and utilization coefficients of S. salsa were very low (0.0145 and 0.3844, respectively), while the N cycle coefficient was high (0.7108). The results of the N turnovers among compartments of S. salsa wetland showed that the N uptake amount of aboveground part and root were 7.764 g/m 2 and 4.332 g/m 2 , respectively. The N translocation amounts from aboveground part to root and from root to soil were 3.881 g/m 2 and 0.626 g/m 2 , respectively. The N translocation amount from aboveground living body to litter was 3.883 g/m 2 , the annual N return amount from litter to soil was more than 0.125(-) g/m 2 (minus represented immobilization), and the net N mineralization amount in topsoil (0-15 cm) in growing season was 1.190 g/m 2 . The assessment of N biological cycle status of S. salsa wetland indicated that N was a very important limiting factor and the ecosystem was situated in unstable and vulnerable status. The S. salsa was seemingly well adapted to the low-nutrient status and vulnerable habitat, and the N quantitative relationships determined in the compartment model might provide scientific base for us to reveal the special adaptive strategy of S. salsa to the vulnerable habitat in the following studies.

Grasses were clipped at threeleaf, heading and seed set. Yield, leaf-to-stem ratio (LSR), botanical composition (BC), crude protein (CP), phosphorus, fibre and in vitro dry matter digestibility (IVDMD) were determined. There were differences (P < 0.05) between the grasses in yield at each growth stage with smooth bromegrass and creeping foxtail having high yields and meadow bromegrass low yields at all growth stages. The BC of most target grasses was greater than 60%. Exceptions were Dahurian wild ryegrass, crested wheatgrass, tall wheatgrass and meadow bromegrass. There were few significant differences between the grasses for LSR, except that Russian and Altai wild ryegrasses and meadow bromegrass had higher LSR (P < 0.05) than the other grasses. Differences in CP, P, neutral (NDF) and acid (ADF) detergent fibres were inconsistent and small at each growth stage but CP and P declined (P < 0.05) while NDF and ADF increased (P < 0.05) with plant maturation. There were differences (P < 0.05) between years and cuts for all traits except between years for yield, BC and LSR at seed set (P > 0.05). Dry matter intake (DMI) NDF and in vivo dry matter digestibility (DMD) were determined for hay cut from each plot using sheep. The relationship between forage NDF and DMI: was used to calculate predicted DMI (PDMI) for all clipped samples. Hay IVDMD differed from DMD (P < 0.05) and the regression DMD = 1.27 IVDMD -5.75 (r 2 = 0.89; RSD = 3.21; P < 0.001) was used to adjust IVDMD to predicted in vivo digestibility estimates (PDMD). PDMD differed (P < 0.05) between the grasses only at heading and seed set. Yield of PDDM (YPDDM), yield of CP (YCP) and the sum of these and PDMI were used to rank the grasses for usefulness as hay or pasture for early or late grazing.
