Abstract:

A field experiment was conducted at Zonal Agricultural and Horticultural Research Station, Mudigere, Chikkamagaluru district, Karnataka to investigate the integrated nutrient management in paddy under hilly zone of Karnataka during kharif season of 2018. The experiment was laid out in Randomized Complete Block Design consisting of ten treatments and replicated thrice. The result revealed that application of 100% RDF + Glyricidia (50%) + Eupatorium (50%) + PGPR (T9) recorded significantly higher total nutrient uptake of NPK (110.81, 48.47 and 61.55 kg ha'’, respectively), yield attributing characters like number of productive tillers per hill (18.41), panicle length (22.29 cm), panicle weight (4.13 g panicle-1) and number of filled grains per panicle (128) as compared to recommended dose of fertilizers alone. Significantly higher 1000 grain weight (25.36g), grain yield(5843 kg ha-1) and straw yield (7477 kg ha-1) was recorded with application of 100% RDF + Glyricidia (50%) + Eupatorium (50%) + PGPR (T9) over other treatments. Combined application of 100 per cent recommended dose of fertilizers + glyricidia (50 %) + eupatorium (50 %) + PGPR treatment found significantly higher bacteria,  fungi  and  actinomycetes  population  (31.78  cfu  ×  105  g-1  of soil, 40.75 cfu × 103 g-1 and 15.11 cfu × 104 g-1 of soil, respectively) and it was followed by 100 per cent recommended dose of fertilizers + glyricidia (50 %) + eupatorium (50 %) (29.50 cfu × 103 g-1, 39.82 cfu × 103 g-1 and 14.70 cfu × 104 g-1 of soil, respectively).
