EFFECT OF WATER FROM DIFFERENT SOURCES AND ASSOCIATED SOIL ON THE GERMINATION, GROWTH AND YIELD OF ORYZA SATIVA (L.)Anitha Kumari C., G. Johnsi Christobel and Beena Lawrence
The physical, chemical and biological factors of water and soil play an important role in the growth of plant. In the present investigation limnological parameters of tap water, pond water (Site I) and pond water (Site II) and the associated soil from the different selected sites were screened. The effect of the sampled water and soil was also investigated forits role on germination, growth and yield of paddy. The physicochemical parameters profile was found to be high in pond water of site II, compared with the other water samples. The associated soil samples of control water contained less potassium, iron and manganese content, while more of nitrogen, potassium and phosphorus was recorded in soil associated with site-II pond water. The heavy metal like copper and zinc content was also found to behigh in site-II pond water associated soil. Significant reduction in the germination percentage (P = 0.0213), (P = 0.0307) root length (P = 0.0001) shoot length and yield (P = 0.0001) of Oryza sativa seedlings was noticed when grown in pond water from site IIandits associated soil. The reason of which are discussed.
