ALTERNATE WETTING AND DRYING IRRIGATION SYSTEM ON GROWTH AND YIELD OF HYBRID BORO RICE (Pages : 28 - 35)

An experiment was conducted at Farm of Sher-e-Bangla Agricultural University, Bangladesh from December 2011 to April 2012 to study the influence of AWD irrigation system on growth and yield of boro rice (HIRA HYBRID dhan2). The experiment consisted nine levels of irrigations (coded from T1-T9) were used. Maximum number of total tillers (26.7/hill), number of effective tillers (21.5/hill), panicle length (31.5 cm), number of grains (215.5/panicle), 1000-grains weight (24.0 g), grain yield (7.8 t/ha) and straw yield (7.5 t/ha) were found from T3 (Start irrigation when water table in the porous tube at 10 cm). Maximum concentrations of grain N (1.20%), P (0.38%), K (0.39%) and S (0.10%) were recorded from T3; similarly maximum concentrations of straw N (0.69%), P (0.20%), K (1.87%) and S (0.10%) were also from T3. Maximum pH (5.9), organic matter (1.26%) were recorded from T1 treatment and total N (0.075%), available P (19.89 mg/kg soil), exchangeable K (0.12 meq/100g soil) and available S (14.66 mg/kg soil) were recorded from T3. T6 (Start irrigation after 7 days disappearance of water) treatment was found as the worst in terms of most of the parameters.Download
