EFFECT OF IRRIGATION AND NITROGEN ON TOMATO YIELD IN THE GREY TERRACE SOIL OF BANGLADESH (Pages : 1 - 4)

An experiment was conducted at Central Research Station, BARI, Joydebpur during rabi season of 2003-04 and 2004-05 to study the effect of irrigation and nitrogen on tomato (Var.BARI Tomato-9). Sixteen treatment combinations comprising 4 irrigation (IW: CPE ratios of 0.6, 0.8, 1.0 and a rainfed condition) and 4 levels of nitrogen (0, 80, 160 and 240 kg ha-1 ) were tested in a split plot design with three replications. Irrigation and nitrogen alone and in combination influenced the yield and yield contributing characters of tomato. From the response curve of average yield data of 2003-04 and 2004-05, optimum N dose was recorded to be 163.3 kg ha-1 and economic dose 182.3 kg/ha. At the same time optimum average fruit yield was recorded 50.43 t ha-1 . Total water use recorded was 15.48, 26.71, 29.10 and 31.20 cm in 2003-04 and 16.80, 27.79, 31.97 and 32.81cm in 2004-05 for rainfed condition and IW: CPE ratios of 0.6, 0.8 and 1.0, respectively. The total number of irrigation at 0.6, 0.8, and 1.0 ratio came out to be 3, 4 and 5, respectively during the rabi season of 2003-04 and 2004-05. Download
