The present research work was undertaken from 2013 to 2016 to evaluate the efficacy of different phosphorus (P) rates and planting geometry for the successful garlic production under saline environment. The experimental design was split-plot with three repeats. Three planting geometry (10cm x 20cm, 15cm x 20cm and 20cm x 20cm) and four phosphorus levels i.e. (i) control (no phosphorus), (ii) P (60 kg ha-1) recommended dose (RD), (iii) 125% P of RD (75 kg ha-1) and (iv) 150% P of RD (90 kg ha-1) were used. Observations included were; plant height, bulb mass, bulb diameter, cloves bulb-1 and bulb yield. Data revealed that phosphorus @ 125% of RD with planting geometry 15cm x 20cm recorded maximum yield and yield attributes with higher economic returns, therefor, under saline-sodic conditions it is proposed as a most cost-effective management practice for garlic cultivation.
