Seasonal patterns and varietal differences in dry matter accumulation and phosphorus absorption in shoot and root of jute (Corchorus spp.)
1989
Ahad, M.A.
Proportionate mass distribution of dry matter in shoot and root and phosphorus concentration and content of five varieties of each C. capsularis and C. olitorius jute at different development stage were measured. The variety JRC-321 showed the highest percentage of dry matter accumulation (72%), concentration (1.13%) and content (80.9%) of phosphorus in shoot and root at 105 days of growth. In the pattern of P absorption (shoot+root), the major share i.e. 54-81 percent of P was found during the growth period of 75-105 days in casularis varieties and 48-68 percent in olitorius varieties of jute. The pattern of DM accumulation and P absorption during the growth period leave a scope to think about the management decision relative to timing of P application to avaid any occurence of P nutrient deficiency likely, will require a fertilizer application in advance of the critical period.
