Effect of salinity water irrigation on maize growth in northwest region


 ABSTRACT:
Because of the scarcity of water resources and serious environment, it becomes much more emergence to develop the water saving agriculture. Drip irrigation and straw mulch both at home and abroad were wide studied. However, How to utilize saline water reasonably, scientificly, efficiently and safely has always been a core problem in farmland irrigation using saline water. Based on the relative research about salinity water irrigation, this paper studied on the effect of different salinity water irrigation and soil salt contents on maize growth in a plastic bucket experiment in Yonggu village, Ningxia shizuishan city of Ningxia located in Yellow River Irrigation district. The main results are as follows, showed that the salinity water had much greater effect on maize emergence rate than that of soil initial salt content. With the increase of irrigation water salinity and soil initial salt content, the maize height all decreased. Under the same soil saline content, the mineralization of water had much greater effect on maize emergence rate than that of soil initial salt content, moreover, with the increase of saline content, the difference become more obviously. Though the salinity water can reduce the production of maize, it is still be helpful to the growth of maize comparing to no irrigation.

Quantitative analysis of civetone and normuscone in secretion from Viverricula indica and in aromatic remedies by gas chromatography-mass spectrometry

Image
ABSTRACT : The quantitation of civetone and normuscone in small Indian civet (Viverricula indica Desmarest) secretion cultivated in Thailand was analyzed by gas chromatography- mass spectrometry (GC-MS). Three main chemical constituents of small Indian civet secretion were civetone, dihydrocivetone and normuscone. The contents of chemical constituents were different between male and female secretion. Civetone (23.6 ± 1.5 µg/mg of secretion) was a major chemical constituent in the female secretion while normuscone (52.1 ± 5.9 µg/mg of secretion) was a major in the male secretion. Both civetone and normuscone were found in civet fur but not in the feces. Aromatic remedies which claimed to use the small Indian civet secretion as an ingredient showed both civetone and normuscone. Linearity range of civetone was 0-50 µg/ml with a correlation coefficient of 0.9717, and of normuscone was 0-80 µg/ml with a correlation coefficient of 0.9965. The average recoveries were 97.3-98.0% in sec...

Antimicrobial activity of aqueous, ethanolic, methanolic, cyclohexanic extracts and essential oil of Nigella sativa seeds

Image
  ABSTRACT : Most of the bacterial pathogens are resistant to existing synthetic antibacterial agents demanding an increasing effort to seek effective phytochemicals as antibacterial agents against such pathogens. Nigella sativa L. (black cumin) seeds play an important role in folk medicine and some of its major constituents are reported to be pharmacologically active. In this present work, Nigellasativa seed extracts were obtained using maceration extraction by various solvents (water, ethanol, methanol, and cyclohexan). The antibacterial and antifungal effects of different extracts and essential oil of seeds were investigated by the agar diffusion method against two gram positive (Bacillus subtilis CIP52.62 ,Staphylococcus aureus CIP4.83) and three gram negative strains of bacteria (Escherichia coli CIP53.126 ,Pseudomonas aeroginosa CIP82.118, Salmonella abony CIP80.39) and one strain of fungi (Candida albicans CIP48.72). All the extracts and essential oil showed varying d...

Analysis of total phenols,total tannins and screening of phytocomponents in Indigofera aspalathoides (Shivanar Vembu) Vahl EX DC

Image
ABSTRACT: The plant Indigofera aspalathoides is popularly known as Sivanar vembu in Tamil belongs to the family fabaceae. The stem is traditionally used for various skin disorders and cancer. In the traditional medicinal system, the leaves, flowers and tender shoot are said to be cooling and demulcent, they are used in the form of decoction for leprosy and cancer affections. Qualitative and quantitative Phytocomponents test were screened in Indigofera aspalathoides. The total content of some important phytochemical constituents like phenols, tannins of Indigofera aspalathoides by studied using spectrophotometric methods. The results showed that the plant is rich in phenols (47.38±1.532) compare than Tannins (34.59±1.788).  Further details Home page URL : http://www.jocpr.com/ For more details PDF Link :  http://www.jocpr.com/articles/analysis-of-total-phenolstotal-tannins-and-screening-of-phytocomponents-in-indigofera-aspalathoides-shivanar-vembu-vahl.pdf
