Journal ArticleDOI
TL;DR: The results indicate the importance of intercropping systems as a promising management practice to alleviate Fe deficiency stress and contributes to better nutrition of plants with Zn, P and K, most probably by affecting biological and chemical process in the rhizosphere.

TL;DR: It is concluded that the beneficial effect of high Ca2+ concentrations on root growth of cotton seedlings in a saline environment may be due to maintenance of K/Na-selectivity and adequate Ca status in the root.
Abstract: . The effects of NaCl salinity on germination and early seedling growth of cotton were studied. Germination was both delayed and reduced by 200 mol m−3 NaCl in the presence of a complete nutrient medium. Seedlings, 7–9 d old, were greatly reduced in fresh weight by salinity. The addition of supplemental Ca2+ (10 mol m−3 as SO42− or Cl−) to the medium did not improve germination but, to a large degree, offset the reduction in root growth caused by NaCl. Roots growing in the high salt medium without supplemental Ca2+ appeared infected by microbes. The cation specificity of the beneficial Ca2+ effect on growth was ascertained by testing additions of MgSO4 or KCl to the NaCl treatments. The contents of K4 and Ca2+ were reduced in both roots and shoots by the NaCl treatments. Supplemental Ca2+ partially offset this effect for K4 in the roots and for Ca2+ in both roots and shoots. Sodium contents were not affected by the supplemental Ca2+. It is concluded that the beneficial effect of high Ca2+ concentrations on root growth of cotton seedlings in a saline environment may be due to maintenance of K/Na-selectivity and adequate Ca status in the root.

TL;DR: Seed inoculation with Rhizobium, Bacillus subtilis and Bacillus megaterium, especially dual and triple combinations, may substitute costly NP fertilizers in chickpea production even in cold highland areas such as in Erzurum.
Abstract: Drawbacks of intensive farming practices and environmental costs of nitrogen (N) and phosphorus (P) fertilizers have renewed interest in biofertilizers. A study was conducted in order to investigate seed inoculation of chickpea with Rhizobium, N2-fixing Bacillus subtilis (OSU-142) and P-solubilizing Bacillus megaterium (M-3) in comparison to control and mineral fertilizer application in controlled environment and in field conditions in 2003 and 2004 in Erzurum (29° 55′ N and 41° 16′ E with an altitude of 1950 m), Turkey. In the controlled environment and in the field trials, single, dual, and triple inoculations with Rhizobium, OSU-142, and M-3 significantly increased all the parameters investigated (plant height, shoot, root and nodule dry weight, N%, chlorophyll content, pod number, seed yield, total biomass yield, and seed protein content) compared with the control treatment, equal to or higher than N, P, and NP treatments. In the field all the combined treatments containing Rhizobium were bet...

TL;DR: Analysis of the effects of salinity on plant growth and yield components of rice by composing 20-day periods of salinization at different growth stages indicates that the differential sensitivity at growth stages can be clearly shown when stages are well defined in the timing treatments.

TL;DR: Cadmium treatment, in general, notably enhanced the concentrations of 2-thiobarbituric acid reactive material (lipid peroxidation products) in pea fractions, presumably due to Cd-induced oxidative stress.
Abstract: Maize and pea plants were treated with 0.0 (control), 0.01 or 0.05 mM Cd in the growing medium for 11 d. Although the total Cd concentration was similar in shoot and root tissues of both species, pea plants showed more severe toxic symptoms. The fresh weight and percentage of water content of root and shoot decreased concomitantly to Cd supply. High Cd levels were found in the cell-wall fraction (Fraction I) and in Fraction IV (soluble) of maize plants, whereas Cd-treated pea accumulated more Cd in the soluble fraction. The protein concentration of Fraction IV of pea shoot and root significantly increased upon treatment with 0.05 mM Cd, whereas maize showed no effect. Furthermore, a previously not visible protein (∼12 kDa), appeared in Fraction IV of pea root grown with the highest Cd supply. Cadmium treatment, in general, notably enhanced the concentrations of 2-thiobarbituric acid reactive material (lipid peroxidation products) in pea fractions, presumably due to Cd-induced oxidative stress.
