ABSTRACT
One experiment was carried out on production stability of crops and fertility build-up of soil, at the farmer's field at Kalyani, Nadia, India under New Alluvial Zone of West Bengal during the years of June 2011 to June 2013, in strip plot design with two (2) main plot treatments (B0 i.e. without biofertilizer and B1 i.e. with biofertilizer) and seven (7) sub plot treatments (F1: 100% of the Recommended dose of fertilizers i.e. RDF, F2: 75% of the RDF, F3: 75% of the RDF +25% of N through FYM, F4: 75% of the RDF +25% of N through vermicompost, F5: 75% of the RDF +25% of N through neem cake, F6: 75% of the RDF +25% of N through groundnut cake and F7: 75% of the RDF +25% of N through mustard cake replicated thrice, with the broader objective of sustaining the intensive cropping system in terms of production and soil health. The treatment ascendancy was observed under the main plot treatment B1 (biofertilzer), sub-plot treatment F6 (75% RDF + 25% N through groundnut cake) in enhancing and sustaining the productivity and soil fertility. The main plot treatment B1 and sub-plot treatment F6 recorded the highest rice grain yields of 4.38 and 5.16 t ha-1 in the respectively. The equatorial bulb diameter and marketable bulb yield of onion was ascertained under the main plot treatment B1 and sub-plot treatment F6 with the corresponding values of 6.69 cm and 23.81 t ha-1 respectively. In case of greengram the treatment dominance was observed under the main plot treatment B1, sub-plot treatment F6 applied to the previous onion crop recording the values of 0.832 and 0.861 t ha-1 respectively.
Key words :
Biofertilizer, Bulb yield, Fertility build-up, Nutrient uptake, Residual greengram.
