Abstract:
A field experiment was conducted during Kharif 2016 on sandy loam soil deficient in B at College of Agriculture, V. C. Farm, Mandya to study the effect of graded levels of borax (5, 10, 15 and 20 kg ha^-1) and gypsum (100 and 200 kg ha^-1) on yield, nutrient content and uptake in irrigated finger millet (Eleusine coracana L.). Significantly higher grain yield of 45.95 q ha^-1 (17.56% higher than the control) and a B:C ratio of 3.06 were also recorded at T₁₂ compared with RDF + FYM (T₁). The Ca, Mg content in grain was higher in T₁₂ (0.63 and 0.30% respectively) which received T₄ + 100 kg gypsum ha^-1 when compared to control (0.50 and 0.23% respectively). The boron concentration in grain was significantly higher (34.38 mg kg^-1) in T₅ (T₁+ 20 kg borax ha^-1) followed by 32.38 mg kg^-1 inT₁₂ (T₄ + 100 kg gypsum ha^-1) when compared to T₁ (20.49 mg kg^-1). Higher total uptake of nitrogen, phosphorous, potassium, calcium and sulphur (166.82, 28.63, 184.54, 67.48 and 30.91 kg ha^-1 kg ha¹, respectively) was observed in T₁₂ (T₄ +100 kg gypsum ha^-1) which were significantly higher than control (T₁). As a result of these findings, applying 15 kg borax ha^-1 + 100 kg gypsum ha^-1 + RDF + FYM is the optimum dose for increasing yield.
