Response of inorganic fertilizers and biomix inoculation on various growth parameters in pearl millet hybrids

The experiment was conducted at research area of Department of Agronomy, Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana during kharif 2016 to assess the effect of Biomix inoculation and chemical fertilizers on plant height, plant population, dry matter accumulation and number of tillers per plant. Plant population at 20 days after sowing (DAS) and at harvest revealed that various combinations of recommended dose of fertilizer (RDF) and Biomix inoculation and pearl millet hybrids did not markedly influence the plant population at both the stages of crop growth. At 40 and 60 DAS and at harvest plant height was maximum in treatment F₆ (185.1, 221.5 and 234.5 cmrespectively) which was statistically at par with F₄and F₅but significantly superior over all other treatments. Dry matter accumulation per plant was affected significantly at 20 DAS and at harvest due to various combinations of RDF and Biomix inoculation. The number of tillers per plant decreased with the advancement of crop age ie from 30 DAS to harvest. Inoculation of bacteria had synergistic and additive effects on plant growth besides reducing the cost of cultivation.
