Biological nitrogen fixing is an important source of nitrogen input in the natural ecological restoration of mine wastelands. The diversity of nifH genes in tailings samples under different plant communities in Yangshanchong and Tongguanshan wastelands in Tongling, was analyzed using polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) approach. The nitrogen-fixing micro...

The study was conducted in the northern Texas Rolling Plains in 1999 to define the relationship between number of cotton aphids, Aphis gossypii Glover, and resulting contamination of cotton lint by honeydew. Whole-plot treatments were three furrow irrigation management treatments: cotton grown without supplemental irrigation (dryland), irrigated cotton with last irrigation in mid August, and ir...

Comprehensive extraction coupled to NMR metabolomics was applied to the identification of active compounds from Morus alba stem bark binding to the adenosine A1 receptor. Orthogonal projection to the least square (OPLS) analysis was used to estimate which compounds significantly correlate with the activity. Based on the loading bi-plot and Y-related coefficient plot, unsaturated fatty acid sign...

In this research, effect of vermicompost and plant growth promoting rhizobacteria (PGPR) on physiological traits of lemon balm under drought stress condition was investigated in year 2012 at Karaj Research Institute of Forest and Rangelands. Experiment was conducted as split-split plot in a randomized complete block design with three replications. irrigation (normal: irrigated to field capacity...

abstract this study was conducted under cold climate condition in khorasan during 2006-2008 growing seasons to evaluation of soil fertility in wheat-based double cropping systems under different rate of nitrogen and return of crop residues. a randomized complete block design with split-split plot arrangement and three replicates was used. main plots were five crop rotations namely: wheat-wheat,...

Java cardamom is an herbal medicinal plant known as the "queen of spices." This research aims to determine influence shading and nitrogen fertilizer dose on total phenolics, flavonoids, antioxidant activity stems rhizomes. The study employed a split-plot design with two factors: level (0, 25, 50, 75%) main plot dosage (N) 0.9, 1.36 g polybag-1) subplots. Twelve months after planting, rhizome st...

During Rabi 2022, a field trial was conducted at the SHUATS Agriculture Crop Research Farm in Prayagraj. The soil experimental plot sandy loamy, with near-neutral response (pH 7.1), low organic carbon content (0.36%), available nitrogen (171.48 kg/ha), phosphorus (15.2 and had an effective soil. K (232.5 kg/ha). experiment set up randomized block design which he repeated nine treatments three t...

This study was carried out to determine the differences in yield and quality characteristics of different plant density nitrogen doses sweet corn (Zea mays L. saccharata Sturt) during 2017 2018 years. research conducted according a split-plot design with three replications Bingol University Faculty Agriculture Application Research Farm. Vega hybrid measured intra-row spacing (15, 20, 25 cm) fiv...

abstractbackground and objectives: all changes in the development stages of plants results in the change of one or more yield components and finally, the ultimate yield and manipulation of these periods means to create new possibilities for increasing yield. accordingly, planting date has a significant impact on plant growth and development during the growth season, so that any shift in plantin...
