Abstract: An experiment on the effect of different planting dates and spacing on the growth and yield of garlic cv. Bianco was carried out at Malakandher Research Farm, NWFP Agricultural University Peshawar during the year 1995-96. Four different plant spacing i.e. 4 cm, 8 cm, 12 cm and 16 cm were kept at four different planting dates i.e 1st. November, 15th November, 30th November and 15th December. The data revealed that both planting dates and spacing significantly affected the number of days to emergence, number of days to maturity, plant height, number of leaves/plant, number of cloves/bulb, bulb size, bulb weight and yield (Kg/ha) Maximum plant height (87.66 cm), number of leaves (8.10), number of cloves/bulb (34.46) bulb size (19.71 cm), bulb weight (44.80 g) and total yield (14166.66 kg/ha) were recorded in plants that were sown on 1st. November with plant spacing of 8 cm, while minimum values were recorded for the mentioned parameters in plots sown on 15th December with plant spacing of 4 cm. Maximum number of days to emergence (12.66) and maturity (198.0) were found in plants sown on 15th December with plant spacing of 4 cm. It is suggested that garlic should be sown before the mid of November with plant spacing of 8 cm under the agro-climatic conditions of Peshawar.
