Phytate is the major storage form of organic phosphorus in soils and plant seeds, and phosphorus (P) in this form is unavailable to plants or monogastric animals. In the present study, the phytase genes phyA and appA were introduced into Brassica napus cv Westar with a signal peptide sequence and CaMV 35S promoter, respectively. Three independent transgenic lines, P3 and P11 from phyA and a18 f...

After nitrogen stress, phosphorus is the second most widely occurring nutrient deficiency in cereal systems around the world. The objectives of this study were: (1) to look at the effect of changes in phosphorus use efficiency and responsiveness on grain yield and quality of triticale and durum wheat with respect to an old tall durum wheat of the early 1940s, Barrigon Yaqui. A two-year field ex...

Phosphorus (P) is a major limiting nutrient reducing crop yields especially in weathered soils of the subtropics and tropics. P exhibits poor mobility availability to plants soil. To overcome deficiency soil, phosphatic fertilizers are added. Global phosphate rock reserves finite, addition not financially ecologically sustainable. Mungbean (Vigna radiata (L.) Wilczek) important grain legume for...

• CO 2 -expanded hexane extraction had higher oil yield than conventional extraction. Extraction selectivity of was controlled by its mole fraction. selectively extracted nonpolar neutral lipids. suppressed the polar phospholipids. is used to extract phosphorus-free bio-oil from rice bran, which constitutes main byproduct milling process, containing approximately 20–25 wt% oil. Optimal conditio...

BACKGROUND Numerous strategies have evolved recently for the generation of genetically modified or synthetic microalgae and cyanobacteria designed for production of ethanol, biodiesel and other fuels. In spite of their obvious attractiveness there are still a number of challenges that can affect their economic viability: the high costs associated with (1) harvesting, which can account for up to...

Fertilization, as one of many important field management practices, can increase crop yields. However, whether different levels fertilization will affect the response wheat yields to inter-annual climate variations and long-term trends is not clear. In this study, 35-year were used investigate responses yield under treatments. The first difference method was de-trend variables stepwise regressi...

This study adapted precision agriculture technologies to commonly used field-scale strip trials and compared fixed and variable phosphorus (P) fertilization for corn (Zea mays L.) and soybean [Glycine max (L.) Merr.]. Differential global positioning receivers, yield monitors, and grid soil sampling were used. Variablerate fertilization reduced considerably the total amount of P fertilizer appli...
