Abstract
The research entitled “Studies on foliar nutrition of growth enhancer on growth and yield of maize (Zea mays L.)” was conducted at Zonal Agricultural Research Station (ZARS), GKVK, University of Agricultural Sciences, Bangalore on red sandy loam soil. The experiment comprised of eleven treatments with three replications laid out in Randomized Complete Block Design. The treatments T1 to T6 includes three nutrient levels of RDF (50%, 75 % and 100 % RDF) applied to soil in combination with foliar spray of growth enhancer (GE) at 10 and 20 ml concentration and T7- urea spray - 0.5 % + 100% RDF, T8- nano N two sprays at 30 and 60 DAS + 50% RDN and 100% P & K, T9- nano N & P two sprays at 30 and 60 DAS + 50% RDNP and 100% K, T10- RDF with FYM and T11- only RDF. The results revealed that foliar nutrition of GE 20.0 ml per litre + 100 % RDF recorded significantly higher plant height (285.5 cm), leaf area (12697 cm2 plant-1 ), total dry matter (530.3 g plant-1), cob length (21.8 cm), number of rows cob-1 (16.0), number of kernels row-1 (40.3), number of kernels cob-1 (568.0), 100 kernels weight (35.9 g), kernel yield (7485 kg ha-1 ), stover yield (8556 kg ha-1), higher net returns (₹ 88,213 ha-1) and B:C ratio (2.50) compared to other treatments. However, it is found on par with GE 10.0ml per litre + 100 % RDF.
