In this study, 33 spring and winter wheat genotypes were analyzed for carotenoid content and composition. Investigated genotypes were divided into four genotype groups i.e., spelt, landraces, old cultivars and primitive wheat. The results showed a high level of variation among the genotypes in amount of carotenoids in the grain with high values (around 4 mg/Kg) especially in one of the genotype...

In this study, a fixed-site field experiment was conducted to study the influence of different combinations of tillage and straw incorporation management on carbon storage in different-sized soil aggregates and on crop yield after three years of rice-wheat rotation. Compared to conventional tillage, the percentages of >2 mm macroaggregates and water-stable macroaggregates in rice-wheat double-c...

The effect of long term conservation tillage (CT) application on soil organic carbon (SOC) concentration, and on stratification ratios (SR) of SOC, soluble organic carbon (SOCs), microbial biomass carbon (MBC) and protease activity (PA) has been studied. The SR was established dividing values of these variables at 0-5 cm depth by values at 10-25 cm depth. The results were compared with those ob...

The effect of water stress induced by NaCl or drought stress was studied on the leaves of wheat, barley, kidney bean and mung bean. After 25 days old, iso-osmotic stresses (200 mM) NaCl and PEG 6000 (180 g 1 ) were applied for 3 weeks old plants. Decreasing leaf dry weight was similar in -1 barley, kidney bean and mung bean under both stresses, while leaf dry weight of wheat decreased more unde...

Analysis of Barriers to the Creation and Development Organic Wheat Production Business Providing Solutions: A Case Growers in Markazi Province

The present study is one step towards sustainable agricultural practices. The results observed for chemical properties like pH, electrical conductivity, available nitrogen, available phosphorus, available potassium, available sulphur, zinc content, organic carbon content and organic matter of vertisol soil indicated that these properties were significantly enchanced at different stages of Soybe...

CT crop–fallow system in the central Great Plains (Shanahan et al., 1988; Halvorson, 1990; Peterson et al., Winter wheat (Triticum aestivum L.)–fallow (WF) using conven1993; Halvorson and Reule, 1994; Farahani et al., 1998). tional stubble mulch tillage (CT) is the predominant production practice in the central Great Plains and has resulted in high erosion potential Winter wheat yields in a WCF...

Yucheng City is located in northwestern Shandong Province, China, and is situated on the Huang-Huai-Hai Plain, the largest alluvial plain in China. In this study, 86 surface soil samples were collected in Yucheng City and analyzed for cation exchange capacity (CEC), soil organic matter (SOM), pH, available phosphorus (avail. P), phosphorus (P), aluminum (Al), and iron (Fe). These soils were als...

the underlying processes, capacity, and longevity of C pools in agricultural lands. One of our current challenges is to quantify the mechanisms, capacStudies have shown that increases in SOC levels are ity, and longevity of C stabilization in agricultural lands. The objectives directly linked to the return of fresh organic material of this study were to evaluate the long-term (10 yr) role of C ...

Soil aggregate stability is an important indicator for controlling soil losses and can improve soil quality, particularly in an area such as the Loess Plateau. The objective of this study was to estimate the differences in soil aggregates across six different land-use systems (grassland, apple orchard, abandoned apple orchard, cropland maize, cropland wheat, and shrub-grassland). For this purpo...
