Abstract:
A field experiment was conducted at Agricultural College Farm, Bapatla during rabi, 2020 to study the effect of boron on growth and productivity of groundnut in coastal sandy soils. The treatments comprised of The treatments comprised of T₁ - RDF, T₂ - RDF + soil application of Borax @ 7.5 kg ha^-1, T₃ - RDF + soil application of Borax @ 10 kg ha^-1, T₄ - RDF + soil application of Borax @ 12.5 kg ha^-1, T₅ - RDF + foliar spray of Borax @ 0.1% at 45 DAS, T₆ - RDF + foliar spray of Borax @ 0.1% at 65 DAS, T₇ - RDF + foliar spray of Borax @ 0.1% @ 45 & 65 DAS, T₈ - T₂ + foliar spray of Borax @ 0.1% at 65 DAS and T₉ - T₃ + foliar spray of Borax @ 0.1% at 65 DAS. The results of the experiment revealed that available boron status of the soil was significantly improved by the application of boron. Whereas physico-chemical properties such as pH, EC, OC and CEC, and available nutrient status of N, P, K, Ca, Mg, S, Fe, Zn, Mn and Cu were not affected by the application of boron.
