The fiscal importance of boron (B) in agriculture, horticulture, and forestry has been past dispute for a number of many years. Even within the final 20 years, the parts the place B deficiency limits plant construction has grown with elevated stories from China, south Asia and southeast Asia. the current quantity is reflective of the becoming wisdom of the importance of low soil B with reviews from Australia, Bangladesh, Brazil, north, relevant and southern China, India, Nepal, and the North West Frontier Province of Pakistan contained herein. Boron deficiency additionally remains to be an issue for crop yield and caliber in components the place B deficiency has been identified for it slow, for instance in Germany and the united states. the matter of low soil B isn't really restricted to results on box crop yield, with papers reporting on depressed wooden yield and caliber in bushes timber (Lambert et al. ), and depressed fruit caliber (Dong et al. ; Smith et al. : Zude et al. ) additionally showing within the current quantity. Globally, Shorrocks (1997)1 estimates that ?? tonnes of B fertiliser is utilized every year in agriculture. the industrial advantages from using B fertiliser haven't been quantified yet are basically huge, immense. mockingly, the transparent financial imperatives for utilizing B fertiliser on low B soils usually are not matched by means of an identical readability of figuring out of the function and services of B in plants.

Abstract Very little literature documents the fate of flue gas desulfurization (FGD) residues under field conditions when applied at agronomic rates. The objective of this study was to document the availability of FGD residue-borne boron (B) for alfalfa (Medicago sativa) uptake when applied to marginally B deficient soils. 1 kg B ha- l , respectively) on a silt loam soil immediately prior to alfalfa seeding. Soil pH increased temporarily, but returned to background levels by the end of the first growing season.

A factorial combination of three levels of B (0, 2, and 4 kg ha- 1) and Fe (0, 10,20 kg ha- 1) were applied. Irrigation was witheld until 28 days after emergence so plants experienced an early water stress. Boron application increased all the yield components and grain yield of wheat as compared to control without the micronutrient application. Iron application increased tillers per m2 , grain weight and grain yield but had no effect on spikelets per spike and grains per spike. However, the combined application of Fe and B did not show additive effects on yield or yield components.
