To investigate the effects of sodium chloride on two safflower cultivars (LRV 51/11 and LRV 51/51(padideh), four levels of salinity: 0, 4, 8 and 12 dS/m, were employed as a factorial experiment arranged in a randomized complete block design with four replication in a controlled environment of the greenhouse during 2008-2009. The desired salinity levels were developed by mixing the required amou...

Soil salinity is one of the most widespread agricultural problems which reduce the field crop productivity. Salinity disturbs the hormonal balance in plants which results in poor growth. Use of plant growth promoting rhizobacteria (PGPR) is considered an economical and environment-friendly approach to combat salinity stress. This study was carried out to investigate the effect of auxin producin...

A passive/active L/S-band (PALS) microwave aircraft instrument to measure ocean salinity and soil moisture has been built and tested. Because the L-band brightness temperatures associated with salinity changes are expected to be small, it was necessary to build a very sensitive and stable system. This new instrument has dual-frequency, dual polarization radiometer and radar sensors. The antenna...

Microwave radiometry at low frequencies (L-band: 1.4 GHz, 21 cm) is an established technique for estimating surface soil moisture and sea surface salinity with a suitable sensitivity. However, from space, large antennas (several meters) are required to achieve an adequate spatial resolution at L-band. So as to reduce the problem of putting into orbit a large filled antenna, the possibility of u...

Soil salinity is considered as one of the major challenges in coastal agriculture in Bangladesh yet geographical extent of soil salinity and nutrients status have received little or no attention. This study investigated the patterns of soil salinity, total nitrogen, phosphorous, potassium and sulfur between agricultural and fallow land along a 90 km distance from the coastline in Noakhali, Bang...

The main scientific objectives of the Soil Moisture and Ocean Salinity (SMOS) mission are to observe two crucial variables: soil moisture over land surface and sea surface salinity over oceans. The mission should also provide information on root zone soil moisture and vegetation and contribute to significant research in the field of the cryosphere SMOS is a demonstrator with broad and ambitious...

Zuo Z.Y., Li X.N., Xu C., Yang J.J., Zhu X.C., Liu S.Q., Song F.B., Liu F.L., Mao H.P. (2017): Responses of barley Albina and Xantha mutants deficient in magnesium chelatase to soil salinity. Plant Soil Environ., 63: 348–354. Soil salinity reduces the plant growth and grain yield in barley. The barley mutants Albina and Xantha, deficient in magnesium chelatase, represent a suitable model object...

SALTIRSOIL (SALTs in IRrigated SOILs) is a model for the medium to long term simulation of soil salinity in irrigated, well-drained lands. Once the algorithms were verified, the objective of our study was to validate SALTIRSOIL under one of several water quality and management scenarios in Mediterranean agriculture. Because drip and surface are the most common irrigation systems in irrigated ag...

Drought and salinity are major factors limiting agriculture in many regions in the world, and their importance is predicted to even increase in the near future in parallel with the ongoing global warming and climate changes. Soil and rhizosphere microbes are potential resources for counteracting such abiotic stresses in plants. The knowledge on the roles of root microorganisms in retaining soil...

Production of heteromorphic seeds is common in halophytes growing in arid environments with strong spatial and temporal heterogeneity. However, evidence for geographic variation (reflecting local adaptation) is almost nonexistent. Our primary aims were to compare the life history traits of two desert populations of this halophytic summer annual Suaeda corniculata subsp. mongolica and to investi...
