Growth, yield, protein content, net photosynthetic rates, stomatal conductance and amino acid profiles were determined in wheat (Triticum aestivum L) plants in response to 50 ppb O3 during the growing season. This concentration is similar to the concentrations of O3 in ambient air. O3 decreased photosynthetic rates (24%) and stomatal conductance (25%), which were reflected in lower growth and yield in terms of number of grains and 100 grain weight. Scanning electron microscopy showed a collapse in the epidermal cells adjacent to stomata that led to stomatal closure and consequently reductions in stomatal conductance. The significance of O3-induced impairment of growth, yield and alteration in amino acid contents are discussed. To the best of our knowledge, this is the first study reporting impact of ozone on protein content, amino acids and yield of wheat in Saudi Arabia.

This study was to conducted to investigate the use of ethylenediurea (EDU) as a possible tool to evaluate O3 effects on wheat (Triticum aestivum L.) plants under field conditions in Jeddah. Wheat plants were expsoed to ambient O3 (AA) and the antiozonant chemical ethylenediurea (EDU) in closed fumigation chambers for the full growing season. Growth, yield and physiology were determined in response to O3 and/or EDU. EDU-treated plants had higher photosynthetic rates (24%) and stomatal conductance (25%), which were reflected in higher growth and yield in terms of number of grains. The present study revealed that EDU could be used as a promising tool to mitigate damaging effects of O3 on under field conditions. EDU protected wheat plants leading to increases in photosynthetic rates, growth and yield.

An experiment has been conducted to assess the real time utility and abundance of organic minerals in cultivation of common wheat, Triticum aestivum L. in Bundelkhand region of Uttar Pradesh with the aim of finding the effect of available soil organic minerals on various biochemicals or chemical characters including yield attributes. For the experiment, the cultivar namely RAJ-4037 which is best for dry land area and crop matures in 120 days. This variety is suitable for bakery and beverage industry, has been taken. The pre availability of manures were measured and the application of various fertilizers have been done as per the recommended dose for the cultivation. The data of various biochemical characters like Dry matter accumulation, Protein content, NPK in grain, NPK in straw, yield and biological yields have been recorded as per standard methods. The results revealed that organic minerals had a significant impact to influence the various biochemical traits such as dry matter accumulation maximum in FYM, Protein content (11.18), NPK (0.60; 0.35 and 0.36) were recorded maximum in vermin compost treatment.
