Effect of nitrogen on carbonic anhydrase activity, stomatal conductance, net photosynthetic rate and yield of mustard

Abstract

Mustard (Brassica juncea L.) cv. Rohini was grown under three levels of urea nitrogen fertilization [0, 2, and 4 g(N) pot-1]. Carbonic anhydrase activity and net photosynthetic rate in leaves of 50 d-old plants as well as yield attributes at harvest increased with increasing levels of nitrogen. Stomatal conductance was not affected, and oil content decreased.
