The experiment was conducted at the research field of Regional Spices Research Centre, BARI Joydebpur, Gazipur in 2010-2011.There were four levels of potassium (0, 80,120 and 160 kg ha-1), four levels of copper (0, 2, 4 and 6 kg ha-1) and three levels of molybdenum (0, 1 and 1.5 kg ha-1). Treatment combinations were as T1: K0 Cu4 Mo1, T2: K80 Cu4 Mo1, T3: K120 Cu4 Mo1, T4: K160 Cu4 Mo1, T5: K120 Cu0 Mo1, T6: K120 Cu2 Mo1, T7: K120 Cu6 Mo1, T8: K120 Cu4 Mo0, T9: K120 Cu4 Mo1.5, T10: No K Cu Mo. The test variety was BARI rasun-1. The treatments were arranged in randomized complete design with three replications. Unit plot size was 1.2 m x 2.0 m. Garlic cloves were planted on 27 October 2011 maintaining a spacing of 15 cm x 10 cm. A blanket dose of N150P60S44Zn4B1 kg ha-1 was applied in all the experiment. The sources of N P K S Zn B were urea, TSP, MoP gypsum, zinc sulphate, and boric acid, respectively. The entire amount of cow dung, TSP, gypsum, zinc sulphate, boric acid and 1/3 each of urea and MoP were applied at final land preparation. The rest amount of urea and MoP were applied in two equal splits at 30 and 55 days after planting (DAP). The crop was harvested on 23 March 2012. Data on plant height, leaf number, neck diameter, bulb diameter, bulb length, single bulb weight, and bulb yield were recorded. The collected data were analyzed following Crop Stat program. Mean separation was made by LSD Test at 5% level of probability.

BARI Rashun-1 responded well to added potassium, molybdenum and copper fertilizer along with blanket fertilizer dose in respect of bulb yield. An amount of K120 Cu2 Mo1 kg ha-1 along with N150P60S30Zn4B1 may be suggested for the production of BARI Rashun-1 in BARI central farm, Gazipur. There was no influence of potassium, molybdenum and copper on controlling tip burn of garlic
