Effect Of Nitrogen And Phosphorus Fertilizers On The Growth Of Senna Siamea

ABSTRACT

A field study was conducted to determine the effect of application of Nitrogen and phosphorus fertilizers and mixture of both fertilizers on the growth of Senna siamea. The result showed variation in growth and response to different fertilizer (KH2Po4, KHNO3, KH2PO4 & KHNO3) application on Senna siamea. There was significant improvement on the height and girth of Senna siamea by the application of KHNO3 and KH2PO4 which resulted in taller plants. KHNO3 application significantly (P<0.05) improved the leaf, stem and root dry weight of Senna siamea than combined KH2PO4 and KHNO3. This suggests that the applications of KHNO3 and KH2PO4 can enhance the growth of some economic crops.
