Due to the lack of scientific knowledge for the use of substrate and best fertilizing method in the growth of Araucaria excelsa, it is crucially important to find the most appropriate planting substrate and fertilizing method. The effect of conventional fertilizing method and the application of Fe nanofertilizer were studied on the growth of A. excelsa in which six fertilizing methods and three...

The effect of foliar spray of different chemicals on the sorghum cultivar KH-333 in four type nutrient medium viz; normal pH, high pH, high bicarbonate (10 mM) and, high pH (8.0) &high bicarbonate (10 mM) on biochemical parameters and the recovery of iron chlorosis in fodder sorghum was examined. The effect of iron chlorosis and sulphydryl compounds on the antioxidant enzymes and active iron co...

Siderophore facilitates iron availability in soil, but its assistance in iron transportation to different plant parts is not reported till date. Therefore, it is worthwhile to study the effect of siderophore produced by Pseudomonas for iron acquisition in the presence and absence of iron. To study these effects, two siderophore-producing Pseudomonas aeruginosa strains RSP5 and RSP8 were selecte...

Phaseolus vulgaris plants, 3, 8, 11, and 13 days old, were inoculated with 0, 2,000, 4,000, or 8,000 second-stage Meloidogyne incognita larvae and maintained under controlled conditions. The photosynthetic rate and the shoot and root concentration of K, Ca, Mn, Fe, Cu, and Zn were determined by destructive assay at 1-27-day intervals and by nondestructive assay of leaves, stems, and roots at 27...

Many metal transporters in plants are promiscuous, accommodating multiple divalent cations including some which are toxic to humans. Previous attempts to increase the iron (Fe) and zinc (Zn) content of rice endosperm by overexpressing different metal transporters have therefore led unintentionally to the accumulation of copper (Cu), manganese (Mn) and cadmium (Cd). Unlike other metal transporte...
