EFFECTS OF AIR POLLUTION ON YIELD OF MUNGBEAN IN LAHORE, PAKISTAN

SHAKIL AHMED
Abstract

---

Experiments were conducted with two commonly grown mungbean varieties viz., M-28 and 6601, in open top chambers and ambient field conditions with the aim of ascertaining the effects of air pollution on yield. The 8-h daily mean ozone concentrations were 41-73 nl litre-1. A considerable reduction of 47.06% and 51.12% in seed yield for M-28 and 6601, respectively were found which are substantially more than might be predicted elsewhere. These reductions in economic yield were due to decrease in both numbers of seed per pod and individual seed weight.
