EFFECT OF NITROGEN AND SULPHUR ON THE GROWTH AND YIELD OF T. AMAN RICE (BRRI dhan87)

Abstract

The experiment was conducted at the Agronomy Field Laboratory, Sher-e-Bangla Agricultural University (SAU), Sher-e-Bangla Nagar, Dhaka-1207 to study the effect of nitrogen and Sulphur on the growth and yield of T. Aman rice (BRRI Dhan 87) during the period from July, 2019 to December, 2019. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications of each treatment and Plant parameters (growth, yield and yield components) and plant analysis data were subjected to statistical analysis through computer based statistical Program STAR (Statistical Tool for Agricultural Research), developed at IRRI. Means were compared by DMRT at 5% level of probability. The experiment consisted of single factor with six treatments such as T 1 : Control (0 kg Nitrogen & 0 kg Sulphur per ha), T 2 :N 60 S 0 (60 kg Nitrogen & 0 kg Sulphur per ha), T 3 :N 90 S 0 (90 kg Nitrogen & 0 kg Sulphur per ha),T 4 :N 120 S 0 (120 kg Nitrogen & 0 kg Sulphur per ha), T 5 (0 kg Nitrogen & 12 kg Sulphur per ha), T 6 : N 60 S 12 (60 kg Nitrogen & 12 kg Sulphur per ha), T 7 :N 90 S 12 (90 kg Nitrogen & 12 kg Sulphur per ha), T 8 :N 120 S 12 (120 kg Nitrogen & 12 kg Sulphur per ha), T 9 :N 0 S 16 (0 kg Nitrogen & 16 kg Sulphur per ha), T 10 (60 kg Nitrogen & 16 kg Sulphur per ha), T 11 :N 90 S 16 (90 kg Nitrogen & 16 kg Sulphur per ha) and T 12 :N 120 S 16 (120 kg Nitrogen & 16 kg Sulphur per ha). The combination of N 120 S 12 (120 kg Nitrogen & 12 kg Sulphur per ha) showed the best result in case of, plant height, leaf length, number of effective tiller per hill, number of effective tillers per hill, panicle length (cm), number of grains per panicle, number of filled grain per panicle, 1000-grain weight (g), grain yield (t ha -1 ), straw yield (t ha ), organic matter, Nitrogen and phosphorus content in post harvest soil. So, it can be concluded that the treatment T 8 (120 kg Nitrogen & 12 kg Sulphur per ha) is the best for T. Aman rice (BRRI Dhan87) cultivation during the Aman season.
