Abstract
A field experiment entitled “Performance of different pearl millet hybrids as influenced by Biomix
inoculation and chemical fertilizers” was conducted during kharif 2016 at Agronomy Research Area
of CCS Haryana Agricultural University, Hisar. The experiment was conducted in split plot design
keeping three replications with the treatments consisting of six fertility management (Control, Biomix,
75 % RDF, RDF,75% RDF + Biomix and RDF + Biomix) and three hybrids ( HHB 234, HHB197 and
HHB 223).
Based on the research investigation it was found that treatment F6 (RDF + Biomix), being at par with
treatment F5 (75% RDF + Biomix ) produced better growth, yield attributes (except number of earhead
plant-1), yield, total N, P and K uptake, grain protein content and yield, gross returns, net returns and
B:C. But, phenological stages, plant population at 20 DAS and at harvest, dry matter accumulation per
plant at 40 DAS to 60 DAS, numbers of tillers plant-1 at 30 DAS and at harvest, tiller conservation
index, harvest and attraction index, K content in grain and stover of pearlmillet hybrid under various
combinations of RDF and Biomix inoculation did not differ significantly.
Among different pearl millet hybrid, significantly taller plants at all the growth stages; longer earhead,
higher dry matter accumulation, 1000 grain weight, grain yield, stover yield, biological yield, harvest
index ,attraction index, protein yield, K uptake in grain and stover ,gross returns, net return and B: C
were obtained in hybrid HHB 223. The difference between the hybrid HHB 197 and HHB 234 for
stover and biological yield were however, not significant.
Various pearlmillet hybrids did not markedly influence days taken to emergence, five leaf stage,
panicle initiation, flag leaf stage and boot stage, plant population at 20 DAS and at harvest, numbers of
tillers plant-1, number of earhead plant-1, tiller conservation index, N content in stover and N uptake in
grain and P content in grain and stover.Non significant interaction between various combinations of
RDF and Biomix inoculation and different hybrids on the grain and stover yield of pearlmillet were
observed.
