Abstract/ Executive Summary:

Higher grain yield (2.45 t ha^-1) was obtained in BRRI dhan34 than that of Kalizira (2.23 t ha-1). Fertilizer application @ 1.8g USG and other inorganic fertilizer ( full dose for T. aman+ PM at 3.5 tha^-1) gave the highest grain yield (2.85 t ha^-1) and lowest grain yield (1.52 t ha^-1) was found at control (no PM and NPKS). Grain yields were affected by the interaction of variety and nutrient management. The highest grain yield (2.88 t ha^-1) was found in BRRI dhan34 coupled with 1.8g USG and other inorganic fertilizer (full dose for T. aman) + PM at 3.5 t ha^-1 and the lowest grain yield (1.24 t ha^-1) was found in Kalizira coupled with control (noPM and NPKS). The combination of fine rice BRRI dhan34 and 1.8g USG and other inorganic fertilizer (full dose for T. aman) + PM at 3.5t ha^-1 appeared as the best treatment combination for the highest grain yield.

Objectives:

The present study was undertaken to achieve the following objectives: to evaluate the yield performance and the appropriate nutrient management for two fine rice varieties and also find out the interaction among integrated management of poultry manure, urea super granules and prilled urea on the yield of fine rice (Kalizira & BRRI dhan34).

Methodology:

The experiment was conducted at the Agronomy Field laboratory, Bangladesh Agricultural University, Mymensingh-2202 during the period from August to December, 2009. The experimental field was a medium high land with silty clay loam soil having pH value of 6.5. The study consisted of the following factors and treatments-Factor A: Varieties of fine rice such as i. Kalizira and ii. BRRI dhan34 and Factor B:Nutrient management such as T1 = Control (no PM and NPKS), T2 = PM at 7.0 t ha^-1, T3 = PM at 3.5 t ha^-1, T4 = Recommended dose of prilled urea and other inorganic fertilizers (i.e. 80, 60, 40, 10, 5 kg N, P2O5, K2O, S and ZnSO4, respectively ha^-1), T5 = Full dose of USG, T6 = 1/2 PU + PKSZn + PM at 3.5 t ha^-1, T7 = 0.9g USG + PM at 7.0 t ha^-1, T8 = 0.9g USG + PM at 3.5 t ha^-1, T9 = 1.8g USG and other inorganic fertilizer (full dose for T. aman) + PM at 7.0 t ha^-1, T10 = 1.8g USG and other inorganic fertilizer (full dose for T. aman) + PM at 3.5 t ha^-1. The experiment was laid out in a randomized complete block design with three replications. There were 60 unit plots in the experiment and the size was 4.0 m x 2.5 m. The sprouted seeds were sown in the nursery beds on 18 July 2009. Forty days aged seedlings were transplanted on 28 August 2009 in the well puddled plot. Three seedlings were transplanted in each hill with a spacing of 25 cm x 15 cm. In the experiment, chemical fertilizers were applied at the rate of 60, 40, 10 and 5 kg ha^-1 of P2O5, K2O, S and ZnSO4, respectively. The whole amount of poultry manure, TSP, MOP, gypsum and ZnSO4were applied at the time of final land preparation. USG @ 100 kg ha^-¹ was applied in the middle of 4 hills of two adjacent rows at a time at 15 DAT. Prilled urea was applied at 15, 30 and 45 DAT, respectively. Intercultural operations such as weeding, irrigation, drainage and plant protection measures were done as and when necessary. The crop was harvested plot-wise at full maturity when 90% of the grains turned into golden yellow. Hills from central 5 m2area of each plot were harvested for collecting data on grain and straw yields. The harvested crop was then bundled separately, tagged properly and brought to the threshing floor and processed as usual. Prior to harvest five hills were selected at random from each plot and carefully uprooted to collect data on yield and yield contributing characters. The collected data were analyzed statistically and the mean differences were adjudged by Duncan’s Multiple Range Test (Gomez and Gomez, 1984) using MSTAT computer program.

Achievement/Findings:

The result of the experiment revealed that the performance of BRRI dhan34 was better than that of Kalizira in terms of grain yield in the Aman season. Among the different nutrient 1.8g USG and other inorganic fertilizer (full dose for T.aman) + PM at 3.5 t ha^-1 gave better performance. It can be conducted that fine rice variety BRRI dhan34 fertilized with 1.8g USG each four alternate hills and other inorganic fertilizer (full dose for transplant aman rice) + poultry manure at 3.5 t ha^-1 gave the highest grain yield with only 55kg N ha^-1in USG form as against 80 kg N ha-1inthe form of prilled urea, which could be a profitable N-management technique.
