A field experiment was conducted during the summer (August-November) season of 2017 at Kandahar, Afghanistan, to study the effect of phosphorus and potassium levels on growth, yield attributes and yield of greengram [Vigna radiata (L.) R. Wilczek]. The experiment was laid out in randomized block design with 10 treatment combinations consisting of 3 phosphorus levels (40, 60 and 80 kg P2O5/ha), 3 potassium levels (20, 40 and 60 kg K2O/ha) and 1 absolute control. Significantly higher plant height (43.9 cm), dry-matter accumulation (15.7 g/plant), leaf area index (1.70), number of pods/plant (22.9), pod length (7.59 cm), number of seeds/pod (7.97), 1,000-seed weight (47.6 g), grain yield (1.55 t/ha), stover yield (4.01 t/ha) and harvest index (27.80) were recorded under the application of 80 kg P2O5with 60 kg K2O/ha over rest of the treatments. The application of 80 kg P2O5 with 60 kg K2O was found better treatments for higher productivity of greengram in semi-arid region of Kandahar, Afghanistan.
