Abstract:

To understand the performance of QPM, hybrid and composite maize to rationalized Nitrogen nutrition, a two year experiment was conducted in the rabi season of 2017-2018 and 2018-2019 at Mondouri experimental farm, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, situated at 22°56’ N latitude, 88°32’ E longitude. It was laid in split plot design with three cultivars in the main plot – HQPM4 (Quality Protein Maize), Shresta (single cross hybrid) and NAC 6004 (composite variety); the sub plots had 6 nutrient schedules in i) T1: control, ii) T2: RDF, iii) T3: RDN75 + Vermicompost @ 2 t/ha, iv) T4: T3+ Azotobactor @ 2kg/ha, v) T5: T4+ Zn, vi) T6: RDN50 + Vermicompost @ 2 t/ha + Azotobactor @ 2kg/ha + Zn. A recommended fertilizer dose of 180:80:80 kg NPK ha-1of which P, K and 20% N were applied as basal dose and remaining dose of N was applied as top dressing splits 25% at 1st top dressing at 4 leaf stage, 30% as 2nd top dressing at 8 leaf stage, 20% as 3rd top dressing at tasselling stage and 5% was top dressed at the grain filling stage. Vermicompost @ 2 tonnes/ha as per treatment were applied and ZnSO4 @ 20 kg/ha was applied in the soil 3days before sowing. Among three maize cultivars hybrid Shresta may be recommended for the eastern plains and HQPM 4 also enjoyed good production potential. It is also concluded that inorganic fertilizer N can be discounted to the extent of 25% and RDN75 + Vermicompost @ 2 t/ha + Azotobactor@ 2 kg/ha + Zn with respective economics of 1.86. The economics favoured hybrid maize, Shresta with a value of 2.1 BCR.
