Description An experiment was conducted during Kharif 2015 at Regional Research Station, Karnal of
CCS Haryana Agricultural University to study the effect of different applied nutrients on growth, yield
and yield attributes and uptake of nutrients by maize. The experiment comprised twelve treatments

conducted randomized block design (RBD) with three replications. Experimental soil was sandy clay
loam in texture having high pH (8.2), medium in organic matter (0.46 %), low in N (120 kg/ha), high in
P (15 kg/ha) and high K (127 kg/ha). Soil contained sufficient amount of micronutrients (Fe, Mn and
Zn). The observation were recorded on plant stand, growth parameters, days to 50 per cent tasseling
and silking, yield and yield attributing characters, uptake of nutrient by plants, quality and economics
of maize. The application of N over control (51.2 q/ha), NP over N alone (56.5 q/ha) and NPK over NP
(71.8 q/ha) significantly increased the maize yield. The application of N over control, NP over N and
NPK over NP in increased the grain yield by 10.3%, 27.0% and 25.1%, respectively. The treatments of
application of NPK with or without micronutrients (Fe, Mn and Zn) were at par in case of growth, yield
and yield attributes of maize. Maximum grain yield (73.4 q/ha) was obtained from the treatment of
NPK+S followed by the treatment of NPK+Zn (72.8 q/ha) and application of nutrients on soil test
based (71.4 q/ha) and minimum in control treatment (40.9 q/ha). Addition of micronutrients
significantly increased their uptake in maize plants compared to alone application of major nutrient (N,
P and K). Protein content (11.0 per cent) and protein yield (8.1q/ha) was found maximum in the
treatment of NPK+S. The application of N over control, NP over N alone, NPK over NP and NPKS
over NPK increased the farmer profit even after additional costs of inputs. The application of
macronutrients (NPK+S) gave maximum (net returns Rs.48705/- and B-C ratio 1.83) followed by the
treatment of NPK+Fe (net returns Rs.47410/- and B-C ratio 1.81) and minimum with control treatment
(net returns Rs.10071/- and B-C ratio 1.20).
