摘要：The experiment was carried out at Horticulture Research Station, Mondouri, BCKV, Mohanpur, Nadia, West Bengal during the years 2014-15 and 2015-16. The cloves were planted during middle of the October in 2.0 x1.5 m plot at 20 x15 cm spacing in with three replications. Two nitrogen fixing biofertilizers (Azospirillum lipoferum and Azotobacter chrococcum), two phosphatic biofertilizers (Vesicular arbuscular mycorrhiza - Glomus fasciculatum) and phosphate solubilising bacteria (Bacillus polymixa) and one potassic solubilizer (Fraturia aurantea) were included. Biofertilizers were applied @ 6 g per plot with 250 g well rotten Farm yard manure. Three levels of recommended dose of NPK i.e., 100%, 75% and 50% were included. Two way combinations of both nitrogenous and phosphatic biofertilizers were followed in Total 12 treatments along with control. Quantitative attributes like plot yield (2.85 kg/3 m2) and projected yield (7.12 t/ha) were noticed in NPK (100%) + Azospirillium + PSB +K solubilizer. Looking to economics of various treatments, maximum net return (Rs 165,043) and B:C ratio (1.55) was obtained from NPK (100%) + Azospirillium + PSB + K solubilizer. Whereas, minimum B:C ratio (0.60) was recorded under NPK (50%) +Azotobacter + VAM + K solubilizer. These results suggested that the optimum production of garlic can be obtained with combined application of 100% NPK and biofertilizers (Azotobacter @ 5 kg/ha +PSB @ 5 kg/ha). The results also indicate the scope of reduction of 25% of inorganic fertilizer through inoculations of biofertilizers.
