EFFECT OF NPK AND S FERTILIZER ON GROWTH AND YIELD OF WHITE JUTE ADVANCED LINE BJC-370

Abstract

A field experiment was carried out in Young Brahrnaputra and Jamuna Floodplain (AEZ-8) at research field in Central Research Station, Manikganj under Bangladesh Jute Research Institute, to study the effect of NPK and S fertilizer on growth and yield of white Jute I3JC-370. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications- The treatments used were T 1 control (0 kg NPK & S ha'). '12 (45,5,30, 10 kg ha" NPK & S respectively), T 3 (45. 10. 60, 20 kg had NPK & S respectively), T4 (45, 15, 90, 30 kg had NPK & S respectively), 15 (90. 5, 30, 10 kg ha 1 NPK & S respectively), T (90, 10, 60, 20 kg ha 1 NPK & S respectively), T7 (90, 15. 90, 30 kg ha" NPK & S respectively), T 5 (135, 5. 30, 10kg ha" NPK & S respectively), T9 (135, 10, 60, 20 kg had NPK & S respectively) and T o (135. 15, 90, 300 kg ha1 NPK & S respectively). The results indicated that the fibre yield, stick yield, green weight with leaves, plant height (PFI) and base diameter (13D) were found statistically significant. The highest plant height (3.44 m) and base diameter (10.22 mm) were recorded in the plants treated with TI) and T5 treatment respectively at 120 DAS. The highest fibre yield (3.70 t ha"), stick yield (8.14 t ha") and green weight with leaves (62.45 t/ha) was found in treatment '1's and the lowest fibre, stick and green weight with leaves yield were found in control treatment. Dry matter production of root, bark, stick and leaves at different stage were significantly varied with different treatments except 30 DAS. The yields of fibre due to ditThrent treatments ranked in the order ofT 3> T 10> To> 'lo> 1 4>17> T5> T,> T> 'I',. The N, P, K and S contents as well as their uptake by jute plants were also increased due to application of different treatments. The treatments had no significant effect on soil properties like soil pH, organic carbon, total N, available P, exchangeable K and available S. The economic analysis demonstrated that the highest net benefit of Tk. 78444 ha" was obtained in T8 treatment.
