Abstract:
A field experiment was conducted carried at Horticultural Experimental Field of College of Agriculture, Central Agricultural University, Imphal, Manipur during September, 2020 to January, 2021. The experiment was laid out in Randomized Block Design (RBD) with 3 replications and 7 treatments with spacing 30 x 30 cm. The treatment consists of T₁ (60:60:210kg NPK/ha), T₂ (6 tonnes of FYM/ha + Azotobacter), T₃ (6 tonnes of FYM/ha + Azospirillum), T₄ (6 tonnes of FYM/ha + Azotobacter + Azospirillum), T₅ (12 tonnes of FYM/ha + Azotobacter), T₆ (12 tonnes of FYM/ha + Azospirillum) and T₇ (12 tonnes of FYM/ha + Azotobacter + Azospirillum). The results of the experiment revealed that among the various treatments, application of T₁ (60:60:210kg NPK/ha) significantly influenced the vegetative parameters viz. Plant height (100.12 cm), number of leaves (11.67) and length of leaf (78.19 cm) which is at par with treatment T₇. However, in flowering parameters viz. number of days taken for flowering (58.05 days), longevity of intact spike (18.92 days), length of the spike (102.25 cm), fresh weight of the spike (80.81g), vase life of the cut spike (13.55 days), number of florets per spike (17.86), yield of spike per hectare (128633.3 Nos.) and corm parameters viz. diameter of the corm (6.24 cm), weight of the corm (64.66 g), number of cormels per plant (22.80) and corm yield per hectare (7.09) was found best in the treatment T₇ (12 tonnes of FYM/ha + Azotobacter + Azospirillum) which is at par with treatment T₁.
