Proper disposal and recycling of different industrial waste materials have long been recognized as a prime environmental concern. The present study evaluated the effects of soil amendment of fly ash, a major industrial waste material, on soil properties, plant growth, productivity and metabolites production of safflower (Carthamus tinctorius L.). The soil was amended with varied concentrations of fly ash (0%, 5%, 10%, 25%, 50%, 75% per pot) prior to sowing under field conditions in the herbal garden of Jamia Hamdard. Sampling was conducted at different growth stages, i.e. pre-flowering, flowering and post-flowering. Our results demonstrate that fly ash concentrations up to 25% improved the physicochemical properties of the soil as compared to non-treated control resulting in increased availability to the plant of macro and micronutrients and thereby stimulating plant growth and productivity. Contents of photosynthetic pigments, sugars, protein, and nitrate reductase (NR) activity increased under 25% fly ash amendment. The highest beneficial effect was found during the flowering stage > pre-flowering > post-flowering stages. Further increase in fly ash concentration reduced the stimulated effects on the plants, exhibiting a minimum under 75% fly ash application. Thus, it was concluded that incorporation of 25% fly ash to the cultivation soil not only improves the physicochemical properties of the soil, but also contributes to better growth, yield and metabolism of safflower.

Plant growth, yield, pigment and protein content of cow-pea were increased significantly at lower levels (20 and 40%) of fly ash but reverse was true at higher levels (80 and 100%). Soil amended by 60% fly ash could cause suppression in growth and yield in respect to 40% fly ash treated cow-pea plants but former was found at par with control (fly ash untreated plants). Maximum growth occurred in plants grown in soil amended with 40% fly ash. Nitrogen content of cow-pea was suppressed progressively in increasing levels of fly ash. Moreover,  Rhizobium leguminosarum  influenced the growth and yield positively but Meloidogyne javanica caused opposite effects particularly at 20 and 40% fly ash levels. The positive effects of R. leguminosarum were marked by M. javanica at initial levels. However, at 80 and 100% fly ash levels, the positive and negative effects of R. leguminosarum and/or M. javanica did not appear as insignificant difference persist among such treatments.Key words:  Meloidogyne javanica; Rhizobium leguminosarum; Fly ash; Growth; YieldDOI: 10.3126/eco.v17i0.4098Ecoprint An International Journal of Ecology Vol. 17, 2010 Page: 17-22 Uploaded date: 28 December, 2010

A field experiment was conducted in 2013 and 2014 at the Agriculture Experimental Station of King Abdulaziz University to study the effects of water deficit treatments at different growth stages on growth, yield and IWUE on cowpea cultivars. Four water deficit treatments were applied T0 (no water deficit), T1 (at vegetative stage), T2 (at flowering and pod setting), T3 (at pod filling), T4 (at vegetative and flowering) and T5 (at flowering and pod filling). The cultivars ‘Balady’ under water deficit T1, T3 and T4 and ‘Cream7’under T1 and T2 produced the highest yield component parameters except number of pods/plant. The highest yield of dry seeds kg/ha was produced by the cultivars ‘Cream7’ under water deficit T1 and T3 and ‘Balady’ under T2. ‘Cream7’ and ‘Balady’ revealed the highest irrigation water use efficiency (IWUE) under water deficit T1, T2 and T4. High seed yield of ‘Balady and ‘Cream7’ can be obtained by applying water deficit at vegetative stage (T1).

AbstractMain conclusion The effect of elevated [CO2] on the growth of tomato plants with reduced GA content is influenced by developmental stage.The increase of carbon dioxide (CO2) in the atmosphere during the last decades has aroused interest in the function of this gas in the growth and development of plants. Despite the known association between elevated CO2 concentration ([CO2]) and plant growth, its effects in association with gibberellin (GA), plant hormone that regulates de major aspects of plant growth, are still poorly understood. Therefore, we evaluated the effect of elevated [CO2] on growth and primary metabolism in tomato plants with drastic reduction in GA content (gib-1) at two different growth stages (21 and 35 days after germination, dag). Disruption on growth, photosynthetic parameters and primary metabolism were restored when gib-1 plants were transferred to elevated [CO2] at 21 dag. Elevated [CO2] also stimulated growth and photosynthetic parameters in Wild type (WT) plants at 21 dag, however, minor changes were observed in the level of primary metabolites. At 35 dag, elevated [CO2] did not stimulate growth in WT plants and gib-1 mutants showed their characteristic stunted growth phenotype.

Rehabilitation is an important stage in mining operations for environmental conservation. However, the shortage of topsoil makesit difficult to achieve rehabilitation in open-cast coal mines. Securing topsoil by mixing soil with fly ash (FA), which is treated asan industrial waste, is expected to solve this issue in coal mines. While mixing soil with FA makes it possible to secure the topsoiland treat industrial waste simultaneously, the high alkalinity of FA and the dissolution of heavy metals from FA may inhibit plantgrowth. This study investigated the effects of FA in the topsoil on plant growth via vegetation tests with simulated topsoil mixedwith FA using Acacia mangium, a species of flowering tree: the FA mixing ratios were set to 0%, 20%, 40%, 60%, and 100%. Thegrowth of Acacia mangium was inhibited with increasing FA mixing ratio, especially from 60% to 80%. However, the growth rate ofAcacia mangium in an FA mixing ratio of 100% was nearly comparable to that in a mixing ratio of 40%. Furthermore, there wereno effects of the physical characteristics and pH conditions in the topsoil on the plant growth at any of the mixing ratios; meanwhile,the accumulated concentration of Al in the plant body increased significantly at an FA mixing ratio of 60%–80%. This suggeststhat the accumulation of Al, which inhibits plant growth, including root growth and its functions, in the plant body inhibited thegrowth of Acacia mangium. Therefore, the most important aspect in terms of rehabilitation concerning the use of FA for securingtopsoil is not the mixing ratio of FA but the amount of Al in the FA and the accumulation of Al in the plant body.
