Abstract:
A field experiment was conducted to evaluate the effect of foliar nutrition and humic acid on growth and growth indices of Foxtail millet (Setaria italica L.) at Agricultural and Horticultural Research Station (AHRS) Bavikere, Tarikere taluk, Chikamagalur district, during late kharif 2020. The experiment consisted of eight treatments and three replication and laid out in RCBD design. Treatments details of experiment consist of viz., Only RDF (T₁), foliar application of 1% urea along with RDF(T₂), foliar application of 0.2% sulphate of potash along with RDF(T₃), foliar application of 0.1% humic acid along with RDF(T₄), foliar application of 1% urea, 0.2% sulphate of potash along with RDF(T₅), foliar application of 1% urea, 0.1% humic acid along with RDF(T₆), foliar application of 0.2% sulphate of potash, 0.1% humic acid along with RDF(T₇) and foliar application of 1% urea, 0.2% sulphate of potash, 0.1% humic acid along with RDF(T₈). Results indicated that, foliar application of 1% urea, 0.2% sulphate of potash and 0.1% humic acid along with RDF (T₈)recorded significantly higher leaf area (cm² plant^-1), leaf area index, leaf area duration (days), total dry matter accumulation (g/plant), absolute growth rate (g plant¹day^-1), crop growth rate (g m^-2 day^-1), relative growth rate (g g^-1 day^-1) at all the growth stages of crop.
