The results showed that thepottern of available P released from SSP was fixing -releasing-fixing-steady state, while that of PAPR was shortlyfixing-slowly releasing-fixing-steady state And the PAPR . SSP and FMP were equally effective as judged by yield, Puptake by plants and extractable P in soils after crop harvesting. The PAPR used as basal fertilizer was more effectivethan that as top dressing, and its residual effect was also obvious.展开更多

A new salt-resistant Indigofera plant variety ＂Feruz-l＂ was producing by the classic methods of genetics and modem biotechnology.Agro-technology of cultivation as main and secondary culture after wheat was developed and recommended to the farmers of the country.The biotechnology of natural plant pigment indigo extraction has been developed and was recommended for using in different fields of industry： textile, pharmacy-pharmacology, perfume-cosmetic, architectural-decorative and food industry. Quantitative and qualitative HPLC （high pressure liquid chromatography） method of determination of plant natural indigo has been also developed.展开更多
