Growth of Groundnut (Arachis hypogaea L.) and its Yield as Influenced by Foliar Spray of Boron along with Rhizobium Inoculation

A field experiment was conducted on groundnut for two kharif seasons during 2009 and 2010 at crop research farm of SHIATS, Allahabad to find out the effect of foliar spray of boron in combination of rhizobium inoculation on growth and yield of groundnut. Inoculation with rhizobium along with application of boron as foliar spray at flowering and pod formation stage had significant and positive effect on growth and yield of groundnut with increased plant height, number of branches, plant dry weight, number of pods/plant, 100 pod weight, seed index and pod yield. Excess spray of boron foliar nutrition led to decrease in the above mentioned parameters.
