Three-year-old citrus trees were grown in the greenhouse to study the effects of fertilizer concentration and root herbivory on plant growth and mineral concentration. In separate experiments, sour orange (Citrus aurantium L.) and Swingle citrumelo (C. paradisi Macf. Poncirus trifoliate L.) plants were treated with a complete fertilizer diluted to provide 25, 100, 200, or 400 ppm N and grown fo...

This experiment was designed to characterize the physical, chemical and microbial properties of a standard commercial horticultural, greenhouse container, bedding plant medium (Metro-Mix 360), that had been substituted with a range of increasing concentrations (0%, 5%, 10%, 25%, 50% and 100% by volume) of pig manure vermicompost and to relate these properties to plant growth responses. The grow...

Effects of NPK 15:15:15 compound fertilizer and planting season on flowering and sex expression of pumpkin were analyzed at the Teaching and Research Farm, Obafemi Awolowo University, Ile-Ife, Nigeria in year 2010. Results deciphered that day to 50% flowering, number of male and female flowers responded to season than fertilizer rates. Late season planting reached 50% flowering 5 days earlier t...

Continuous use of chemical fertilizers has deteriorated the soil health and made the use of organic matter essential to restore the soil health and productivity. The availability of organic matter is again a problem because of the increase in area under crop cultivation. Thus recycling of the available organic wastes from the existing gardens especially in perennial crops gets more importance. ...

ABSTRACT- To investigate the effects of bio-chemical and organic fertilizers on yield and seeds NPK contents of pumpkin (Cucurbita pepo var. styriaca), an experiment was conducted at the Research Farm of Kurdistan University in 2009 growing season. Treatments were included 1) control, 2) seeds inoculated with free-living N fixing bacteria (NFB), 3) seeds inoculated with phosphate-solubilizing b...

chemical fertilizers are threat in hman life and today application of biological fertilizer find more important. this study performed in order to evaluate the effects application of biofertilizers with urea fertilizer on yield, protein percentage and numbers of eyes in plant, plant height and chlorophyll spad in potato var. marphona. a factorial experiment was conducted based on randomized comp...

Revegetation efforts generally have failed to establish substantial cover on bentonite mine spoil, but certain amendments have shown promise for improving spoil as a plant growth medium. These growthpromoting improvements were at least partially the result of effects of these amendments on spoil chemistry. We undertook this study to determine the effects of selected amendments (gypsum, fertiliz...

The effects of integrated nutrient management (INM) by municipal solid waste manure (MSWM) on wheat yield were studied in rice-wheat and cotton-wheat systems. each site was used as an independent experimental unit. Two fertilizer doses (conventional and site-specific) were applied in each of three improved techniques: chemical fertilizers, and MSWM plus chemical fertilizers with and without pes...
