(Unpublished M.Sc. thesis). Punjab Agricultural University, Ludhiana, Punjab, India.https://krishikosh.egranth.ac.in/handle/1/5810202787The present investigation was conducted at vegetable research farm, biochemistry laboratory and soil science laboratory, Punjab Agricultural University, during rabi seasons of 2020-21 and 2021-22 to standardize the potassium and sulphur dose for growth, yield and quality of garlic. The experiment was laid in randomized complete block design and replicated thrice. Variety ‘PG-18’ was used as plant material. The experiment comprised of sixteen treatment combinations with four levels of potassium (0, 20, 40 and 60 kg K ha-1) and sulphur (0, 10, 20 and 30 kg S ha-1). Potassium and sulphur were applied as basal dose at bed preparation and all the agronomic practices were followed in accordance with package of practice. It was observed from the results that with the application of 60 kg of potassium along with 30 kg sulphur, growth parameters like, plant height (82.8 cm), bulb diameter (5.24 cm), total bulb yield(14.17 t ha-1), quality parameters like allicin (12.64 mg g-1) was recorded highest. Highest Benefit Cost ratio was also observed with same treatment combination. It was observed that highest bulb yield was in the same combination of treatments with highest nutrient uptake status. Therefore, from the results it was found that 60 kg of potassium along with 30 kg sulphur treatment was found beneficial for growth, yield and quality of garlic and it is recommended for North Indian conditions.EnglishThesis
