Abstracts |
The yield and nutrient uptake of Plantago ovata were studied using dual inoculation with AM fungi (Glomus fasciculatum) and Azotobacter chroococcum. The experiment was conducted for two consecutive years, with two levels of chemical fertilizers (F1: N-P-K : 24-24-32 kg ha-1) and (F2: N-P-K : 30-30-40) kg ha-1. Inoculation with the AM fungi and Azotobacter chroococcum generated encouraging results; seed yield (1120.7 kg ha-1), husk yield (297.1 kg ha-1), plant height (40.4 cm), spike plant-1 (33.6), and 1000 seeds weight (1.793 g) were highest with treatment T12 (F2 fertilizer level+both bioinoculants) followed by treatment T9 (F1 fertilizer level+both bioinoculants), T10 (F2+A. chroococcum), T11 (F2+AM fungi), as compared to T1 (control), T2-T4 (bioinoculants) and T5-T6 (F1 and F2 fertilizer levels). The nitrogen uptake was more in Azotobacter treated plants, while higher P and K uptake was attained in AM fungi inoculated plants. The survival count of inoculated bacteria was highest on 60 days after inoculation and declined thereafter. Economic analysis revealed the net profit from seed and husk was highest in T9 using dual inoculation of microbes with 80% of recommended dose of fertilizer followed by T12 and T10. |
