All the parameters i.e., days to emergence, days to flowering, days to physiological maturity, number of pods per plant, number of seeds per pod, 100-seeds weight, biological yield, grain yield were significantly affected by sowing dates. Less days to emergence (6.6), less days to flowering (40) and less days to physiological maturity (75.7) were recorded. Biological yield was maximum for June 15 (6000 kg ha -1) followed by July 01(5439 kg ha -1). Number of pods per plant, number of seeds per pod, 100-seeds weight (g), grain yield (kg ha -1) got highest value of 30.2, 5.1, 4.26 and 825 respectively for July 01 sowing. Effect of the various mashbean varieties was significantly different for number of pods per plant, number of seeds per pod, biological yield and grain yield. Among these parameters highest number of pods per plant (20.6) for NARC Mash-1, higher number of seeds per pod (4.9) for NARC Mash-3, greatest biological yield (4400 kg ha -1) for NARC Mash-4 and more grain yield (557.1 kg ha -1) for NARC Mash-1. Interaction between varieties and sowing dates did not significantly affect any parameter. It may be concluded that July 01 sowing date and NARC Mash-1 variety appeared to be suitable for irrigated condition of Peshawar valley.
