Growth and yield of summer Pearlmillet (Pennisetum glaucum L.) as influenced by planting density and nitrogen levels

Abstract

A field experiment was conducted during the Zaid season 2018 at the Crop Research farm of Agronomy, Naini Agricultural Institute, SHUATS, Allahabad (U.P.) to study Effect of planting density and nitrogen levels on growth and yield of kharif dual purpose pearlmillet (Pennisetum glaucum L.)”. The experiment consisted of three planting density viz., comprising 2 planting density D1, Normal distance (45 cm x 10 cm); D2, High density (22.5 cm x 10 cm) fb alternate row harvest at 45 DAS and 4 nitrogen levels (N1, N = 60 kg ha-1; N2, N = 80 kg ha-1; N3, N = 100 kg ha-1 and N4, N = 60 kg ha-1). was laid out in randomized block design with three replications. The result revealed that treatment T8 (High density planting fb alternate row harvest at 45 DAS+120 kg nitrogen ha-1) produced significantly the highest plant height at 20,40, 60, 80 DAS & Harvest (10.44 cm,31.45 cm,166.10 cm,173.36 cm 175.37 cm), At 40 DAS higher no of tillers plant-1 (2.47 no) were recorded with the treatment T8 (High density fb alternate row harvest at 45 DAS+120 kg nitrogen ha-1) at 40,60,80 DAS and harvest are non-significant, yield atributes show that T4 Normal density planting along with 120 kg Nitrogen ha-1 recorded highest ear head length, grain weight earhead-1, 1000 grain weight, grain yield and harvest index which was at par with T8 High density planting along with 120 kg Nitrogen ha-1 fb alternate row harvest at 45 DAS.
