Abstract
Abstract A field trial was conducted on clay loam soil (Typic Haplustalf) with rice (Var. IR.60 ) as the test crop to find out its rooting behaviour under submerged conditions as influenced by zinc sources. Three different zinc sources viz., zinc sulphate, zinc blended urea and zinc blended suphala were applied in different combinations. Root length density was measured at 40, 55, 70 and 85 days after transplanting at 5 cm intervals of depth upto 25 cm. The results revealed that root length density decreased with depth in all the treatments at all the stages. There was progressive increase in root length density with advancing age of the crop. Zinc sulphate applied alone and in combination with NPK had increased the root length density compared to absolute control and NPK alone in the initial stages. Zincated urea provided higher root density compared to 2incated suphala.
