 ABSTRACT

A field experiment was carried out to study the effect of nutrient levels and plant growth regulators on nutrient uptake of N, P, K and economics of pearl millet during rabi 2016 at TNAU, Coimbatore, Tamil Nadu, India. Ten treatments with nutrient levels and plant growth regulators were imposed with three replications using RBD. Growth regulators are chemical substances helps to enhance plant growth, development of for high yield and improved grain quality or facilitated harvesting. The uptake of nutrient increase in grain and stover due to higher N and P content.  Application of 125 % RDF + foliar application of NAA @ 40 ppm at 20 and 40 DAS (T7) enhanced the N uptake significantly at all the three stages of pearl millet i.e., 30 DAS, 60 DAS and at harvest (10.6, 54.6 and 70.6 kg/ha. respectively) and uptake of phosphorus i.e., 3.04, 10.25 and 15.75 kg/ha at 30 DAS, 60 DAS and at harvest respectively. Application of 125 % RDF + foliar application of NAA @ 40 ppm at 20 and 40 DAS (T7) had significantly more potassium uptake (20.3, 70.00 and 82.75 kg/ha) at 30 DAS, 60 DAS and at harvest respectively. Application of 100 % RDF + foliar application of NAA @ 40 ppm at 20 and 40 DAS (T8) recorded higher net returns ( 34,410/ha) and B:C ratio (2.0)

Key words: pearl millet, plant growth regulators, NAA, Chloromequat chloride, Nutrient uptake, Economics and B:C ratio
