INFLUENCE OF FIELD DEEP UREA ON NITROGEN, PHOSPHOROUS, POTASSIUM AND SULFUR UPTAKE AND YIELD PERFORMANCE OF GREEN SUPER RICE

A field experiment was conducted to investigate the Influence of field deep fertilisers on nitrogen, phosphorous, potassium and sulfur uptake and yield performance of green super rice during the period of 15th January to 16th May 2015. Soil samples were collected at a depth of 0-15 cm from the sara soil series at Jessore District in Bangladesh. The experiment was laid to fit a completely randomised design (CRD) with five treatments (constituted with organic, inorganic and mixed fertiliser along with different levels of field deep urea) each having three replications. Results indicate that the highest amount of macronutrient uptake was found in inorganic treatment (T2) with field deep urea. But mixed fertiliser (T4) with field deep urea showed nearer results with a specific advance period of yield performance of green super rice than other treatments. So, deep placement of urea is better than traditional placement. Macronutrient uptake was significantly (P <0.05) influenced by various treatments and application procedure of urea. Yield performance in the sara soil series of Jessore District will require field deep urea with mixed fertiliser (T4) to get advance production of rice with less damage to soil health than inorganic fertiliser (T2). In addition, inorganic fertilizer can give quite higher production than mixed (T4) or organic fertilizer (T3). In case of T4 the grain formation and harvesting period occurred 8-10 days before the other treatments which can be used in future if it is essential to get advance production.
