Plant Growth-promoting Rhizobacteria: Potential Green Alternative for Plant Productivity

Use of plant growth promoting rhizobacteria (PGPR) for the benefits of agriculture is gaining worldwide importance and acceptance and appears to be the trend for the future. PGPR are bioresources which may be viewed as a novel and potential tool for providing substantial benefits to the agriculture. These beneficial, free-living bacteria enhance emergence, colonize roots, stimulate growth and e...

OVERVIEW: PART OF A SPECIAL ISSUE ON PLANT NUTRITION Plant nutrition for sustainable development and global health

†Background Plants require at least 14 mineral elements for their nutrition. These include the macronutrients nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulphur (S) and the micronutrients chlorine (Cl), boron (B), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), nickel (Ni) and molybdenum (Mo). These are generally obtained from the soil. Crop production is o...

Bromeliad-living spiders improve host plant nutrition and growth.

Although bromeliads are believed to obtain nutrients from debris deposited by animals in their rosettes, there is little evidence to support this assumption. Using stable isotope methods, we found that the Neotropical jumping spider Psecas chapoda (Salticidae), which lives strictly associated with the terrestrial bromeliad Bromelia balansae, contributed 18% of the total nitrogen of its host pla...

Effects of Near Ultraviolet and Green Radiations on Plant Growth.

Test Systems. Tagetes erecta L., Dwarf Pigmy French Marigold (Burpee 4166) was planted in soil in polyethvlene boxes; radiation treatments were started immediately. Impatiens Balsamina L.. Holsti Hybrid (Burpee 4107) and Lycopersicon esculenturit Mill., Rutgers (Burpee 5061) were similarly grown; radiation treatments were started when the seedlings were 1 cm tall. One week after planting, the s...
