Abstract
A field experiment was conducted during kharif-2017 at Agricultural College and Research Institute, Madurai in a factorial randomized block design. The present research was designed by nine treatment combinations considering three dates of sowing D1: II fortnight of June, D2 : I fortnight of July and D3 : II fortnight of July and three nitrogen levels N1: RDN (80 kg ha-1), N2 : 75% RDN (60 kg ha-1) and N3 : 125% RDN (100 kg ha-1) to study the growth and yield components of pearlmillet grown with variety CO (Cu) 10. The crop sown on I fortnight of July with 125 % RDN recorded maximum growth parameters, yield components and recorded significantly highest grain yield. The lowest was recorded in crop sown on II fortnight of July with application of 75% RDN.
