The yield and yield components of pea (Pisum sativum L.) as influenced by salicylic acid

The effects of 0 M, 10(-5) M and 10(-4) M salicylic acid (SA) applied by three different modes (seed treatment, seed treatment plus foliar spray and foliar spray) in four pea (Pisilum sativum L.) varieties viz., Meteor, Climax, Greenfeast and Rondo were evaluated. Arnong the varieties the highest green pod yield of 5255 Kg ha(-1) was obtained in variety Meteor followed by variety Greenfeast (4452 Kg ha(-1)). The maximum increase in all the yield and yield components was observed in the pea plants treated with SA concentration 10(-4) M over SA 10(-5) M and SA 0 M. Moreover the increase in the yield and yield components was more pronounced in the plants that received the SA twice (seed treatment and foliar spray) at two different stages of development.
